Duplicating record isn't duplicating image Posted: 31 Jul 2016 07:52 AM PDT I'm trying to duplicate my record and using the amoeba gem. Everything copies fine except for the image (which is uploader via carrierwave) For the image I tried doing a customized setting in amoeba like this: amoeba do customize(lamba { |original_object, new_object| new_object.photo = original_object.photo }) but that just returned the path of the image still which when loading is looking in the individual record id.

Rails: Accept optional nested Image; allow to add later if nil Posted: 31 Jul 2016 07:09 AM PDT I have a simple Article model associated with an Image model. The relationship is currently one-to-one (might change later but is fine for now). Everything works fine when I create an Article from scratch and add an Image to it. Here's the catch: I would like the Image to be optional at creation, but also I would retain the option to add an Image at a later stage. However, I am not sure how to handle that through the edit action. I have tried this: def edit @article = Article.find(params[:id]) if @article.image.nil? @article.image = Image.new end render 'articles/edit' end ... which results in: ActiveRecord::RecordNotSaved in Admin::ArticlesController#edit Failed to save the new associated image. The form currently looks like this: <%= f.fields_for :image do |image| %> <div class="form-group"> <%= image.label :image, "Article image" %><br/> <%= image_tag(@article.image.path.thumb.url) %> <%= image.file_field :path %> </div> <div class="form-group"> <%= image.label :caption %> <%= image.text_field :caption, class: 'form-control' %> </div> <div class="form-group"> <%= image.label :credits %> <%= image.text_field :credits, class: 'form-control' %> </div> <% end %> How can I accomplish optional nested images that can be added through the edit form later on? Thanks!

.html.erb set div doesn't work correctly Posted: 31 Jul 2016 03:45 AM PDT I just created a scaffold in rails and list all stories in index page, and _stories.html.erb is partial which was rendered in index.html.erb I want each story div has a red background for example: .storyCell{ background-color:red; height:100px; } _stories.html.erb <tbody> <% @stories.each do |story| %> <div class="storyCell"> <tr> <td><%= story.content %></td> <td><%= story.finished %></td> <td><%= link_to 'Show', story %></td> <td><%= link_to 'Edit', edit_story_path(story) %></td> <td><%= link_to 'Destroy', story, method: :delete, data: { confirm: 'Are you sure?' } %></td> </tr> </div> <% end %> </tbody> But the result is the red div all in top of the story model properties. Thank you!

How to use Google::Auth::Stores::FileTokenStore.new for Google Calendar API Posted: 31 Jul 2016 03:44 AM PDT I'm trying to access the Google Calendar API from my Rails app. The official guide is rather scarce, but I think I get most parts except for Google::Auth::Stores::FileTokenStore.new - what's the purpose of this and how should I use it in a traditional Rails app?

How to upload videos (resumably) to Vimeo from a Rails 5 app? Posted: 31 Jul 2016 05:31 AM PDT I am trying to upload videos to my Vimeo account from my RoR 5 application using the Vimeo API and the option "Resumable HTTP PUT uploads": https://developer.vimeo.com/api/upload/videos#resumable-http-put-uploads For this I'm using Paperclip to upload the video to my application and then I want to do a multipart PUT request to send the file with the Content-Length and Content-Type headers as the API documentation specifies, but I don't have an idea how to send the video file via PUT request, any help?

Grab current users "admin" attribute from database Posted: 31 Jul 2016 02:18 AM PDT I have a Users model that has a field which is admin. This field is a boolean. I only want a user who is an admin (admin field = true) to be able to create a "Season." How on earth would I do this on rails? I don't even know where to start. I assume that in my application controller I could define "current_user_admin" and in my view use "current_user_admin?" to show the "create season" link. But what do I do in the model? I do have current_user defined as such in my application_controller: @current_user ||=User.find_by id: session[:user_id] if session[:user_id] Am I going down the right path? Any guidance is appreciated!

Rails 5: How to send and process large files (200Mb) via Rails API? Posted: 31 Jul 2016 01:44 AM PDT I'm looking for the general concept, but every tip can be useful. The client (mobile) has to send a large file to Rails API. It's a some text file with raw data. How can the Rails API get the large file from client? Should it be done by HTTP request, websockets? Should the files be sent in chunks?

Why does have_selector "#MyId" fail when match /id=\"MyId\"/ passes? Posted: 31 Jul 2016 02:23 AM PDT I have a rails helper that generates a form #helpers/my_helper.rb def build_form form_for object, url: object_path, method: :post do |f| html = f.text_input :field html += f.submit html.html_safe end end And tests for this helper #spec/helpers/my_helper_spec.rb describe MyHelper do it { expect( helper.my_helper ).to have_selector "form[action='#{objects_path}'][method='post']" } # PASSES it { expect( helper.my_helper ).to have_selector "#object_field" } #FAILS - but this should pass it { expect( helper.my_helper ).to match /id=\"object_field\"/ } # PASSES end I am still learning rspec, so this may be an obvious question. Why are these tests failing when using have_selector on the inputs. And yet have_selector correctly passes on the form tag, and match passes on the input ID.

jQuery.event.props is undefined Posted: 31 Jul 2016 01:08 AM PDT I'm using jquery.event.move to create move events on touch devices. The script is throwing an error on line 580. 570 // Make jQuery copy touch event properties over to the jQuery event 571 // object, if they are not already listed. But only do the ones we 572 // really need. IE7/8 do not have Array#indexOf(), but nor do they 573 // have touch events, so let's assume we can ignore them. 574 if (typeof Array.prototype.indexOf === 'function') { 575 (function(jQuery, undefined){ 576 var props = ["changedTouches", "targetTouches"], 577 l = props.length; 578 579 while (l--) { 580 if (jQuery.event.props.indexOf(props[l]) === -1) { 581 jQuery.event.props.push(props[l]); 582 } 583 } 584 })(jQuery); 585 }; When it gets to line 580 it throws Uncaught TypeError: Cannot read property 'indexOf' of undefined The way I understand it is that jQuery.event.props is undefined? Shouldn't this array be present by default in jquery? I've "installed" jQuery in my rails app as a gem (jquery-rails 4.1.1) Any idea what I could do?

Unable to permit additional parameters in device#accept invitation Posted: 31 Jul 2016 12:58 AM PDT I'm unable to permit additional parameters in "invite#accept".

But in the method "accept_resource" there're still only 3 old parameters accepted, other didn't come through, although they present on a form. class MyInvitationsController < Devise::InvitationsController before_filter :configure_permitted_parameters, if: :devise_controller? before_filter :update_sanitized_params, only: [:edit, :update] def edit puts "edit...." super end private def accept_resource puts "accept_resource..." resource = resource_class.accept_invitation!(update_resource_params) # but it still permits only :password, :password_confirmation and :invitation_token resource end protected def configure_permitted_parameters puts "configure_permitted_parameters..." devise_parameter_sanitizer.permit(:sign_up, keys: [:aaa, :bbb, :ccc, :password, :password_confirmation, :invitation_token]) end def update_sanitized_params puts "update_sanitized_params..." devise_parameter_sanitizer.permit(:sign_up, keys: [:aaa, :bbb, :ccc, :password, :password_confirmation, :invitation_token]) How to fix that? devise devise 4.2, devise_invitable 1.6

Updating Heroku database without deleting anything Posted: 31 Jul 2016 12:46 AM PDT I have my project in production right now using Heroku, but I want to add more tables and such to my rails database and than push it to Heroku. And I also plan on upgrading to Rails 5. Are there any general rules that I should or shouldn't be doing so that my existing databases of Users does not accidentally get deleted? Also, i noticed that Heroku has a 'backup' feature. Does this backup feature save a copy of all my Users information (email, name, pw, ect) which I can restore back at any certain time in case the unthinkable happens?

Turbolinks not ignoring page in Rails app Posted: 31 Jul 2016 12:09 AM PDT The front page view ('Welcome/index.html.erb') : https://github.com/bfbachmann/Blog/blob/master/app/views/welcome/index.html.erb Rails Version: 4.2.6 The overarching problem: I am trying to get my THREE.js model to show up properly inside my rails app. Everything works fine when I load the page by typing its URL into the search bar in my browser or if I hit reload or 'command' + R (on Windows its 'ctrl' + 'R') on my keyboard. I have a feeling this is because Turbolinks is not fired when these actions are performed. This leaves my model in the state it should be in as shown below. HOWEVER... when I click one of the links in the navbar (blog, projects, about etc.) and then return to the home page by clicking the house icon either the rotation speed of the model doubles, or the model is duplicated. If the model is duplicated one copy stands still while the other rotates at its regular speed as shown below. Broken Version Screenshot What I've Tried I have a strong feeling Turbolinks is to blame for this. So I tried to get Turbolinks to ignore that page by adding 'data-no-turbolink' to the body of that page... it didn't work. In fact I think Turbolinks was not even ignoring the page because it still loaded much faster when I clicked the home page link than when I re-entered the page's URL. I tried adding a callback that would stop all the javascript responsible for the front page from running when the user navigates away from the page. This can be found in the view I linked at the top. I know this callback gets fired because I tested it. That also doesn't solve the problem. Finally, I should also mention that I am using the JQuery-Turbolinks gem to resolve conflicts between the two. Any help would be much appreciated. I have been trying to solve this problem for weeks. Edit: I forgot to mention that I have read that Turbolinks has problems with inline javascript... this could be causing that problem. Edit: It appears my javascript is being run every time I load ANY page on my site even though it is inline javascript. I can't understand why.

Error after removing column in database Posted: 31 Jul 2016 07:11 AM PDT I removed a column named assignment from my assignments database and encountered the following error: assignments_controller.rb: class AssignmentsController < ApplicationController before_action :authenticate_user! before_action :set_assignment, only: [:show, :edit, :update, :destroy] # GET /assignments # GET /assignments.json def index @assignments = Assignment.all end def mylist @assignments = Assignment.where(user_id: current_user.id).find_each end # def bidders # @bids = Bid.where(bidders_params).find_each # #@bidders = User.where(user.id => @bids.user_id).find_each # @bids.each do |bid| # @bidders = User.where(user.id => bid.user_id).find_each # end # end # def bidders # idders_ids = Bid.where(bidders_params).pluck(:user_id) # @bidders = User.where(id: bidders_ids) # end # GET /assignments/1 # GET /assignments/1.json def show end # GET /assignments/new def new @assignment = Assignment.new end # GET /assignments/1/edit def edit end # POST /assignments # POST /assignments.json def create @assignment = Assignment.new(assignment_params) respond_to do |format| if @assignment.save format.html { redirect_to @assignment, notice: 'Assignment was successfully created.' } format.json { render :show, status: :created, location: @assignment } else format.html { render :new } format.json { render json: @assignment.errors, status: :unprocessable_entity } end end end # PATCH/PUT /assignments/1 # PATCH/PUT /assignments/1.json def update respond_to do |format| if @assignment.update(assignment_params) format.html { redirect_to @assignment, notice: 'Assignment was successfully updated.' } format.json { render :show, status: :ok, location: @assignment } else format.html { render :edit } format.json { render json: @assignment.errors, status: :unprocessable_entity } end end end # DELETE /assignments/1 # DELETE /assignments/1.json def destroy @assignment.destroy respond_to do |format| format.html { redirect_to assignments_url, notice: 'Assignment was successfully destroyed.' } format.json { head :no_content } end end private # Use callbacks to share common setup or constraints between actions. def set_assignment @assignment = Assignment.find(params[:id]) end # Never trust parameters from the scary internet, only allow the white list through. def assignment_params params.require(:assignment).permit(:education_id, :subject_id, :gender_prefer, :timeslot, :duration, :budget, :budget_unit, :assignment_info, :user_id, :region_id) end def bidders_params params.permit(:assignment_id) end end I'm well aware that it could be because of the .require(:assignment) in: params.require(:assignment).permit(:education_id, :subject_id, :gender_prefer, :timeslot, :duration, :budget, :budget_unit, :assignment_info, :user_id, :region_id) I've tried changing that line to: params.permit(:education_id, :subject_id, :gender_prefer, :timeslot, :duration, :budget, :budget_unit, :assignment_info, :user_id, :region_id) but to no avail. Please help me on this matter. Thanks in advance!

How to get posts with votes between two numbers? - Rails Posted: 30 Jul 2016 08:00 AM PDT I tried this, but it didn't work, it returns all posts Post.where(' -1 < cached_votes_score < 10') although Post.where(' cached_votes_score < 10') works, any thoughts on this?

Nested resource under users, I want only the current_user to be able to access Posted: 30 Jul 2016 07:43 AM PDT I have the following under my routes.rb: resources :users do resources :submitted_terms, only: [:index, :create, :show] end I only want the current_user (the logged in user) to be able to see their own submitted_terms in terms of the index and show views. They shouldn't be able to see anybody else's index and show views and other people shouldn't be able to see theirs. I think I know how to implement this but it feels sort of messy to me. Any thoughts?

Specificity issues with bootstrap Posted: 30 Jul 2016 07:38 AM PDT Why do I need !important for the margin:0 to show? @import "bootstrap-sprockets"; @import "bootstrap"; .alert { margin: 0 !important; } and *= require_tree . *= require_self

Rails App behind Wordpress using fastcgi_intercept_errors Posted: 30 Jul 2016 06:54 AM PDT I'm starting a migration of a WordPress website to a rails application. The migration needs to be done gradually over the next few months, so I'll need to be able to run both sites in parallel. Using fastcgi_intercept_errors on a test environment I've managed to get any 404 errors returned by WordPress to forward on to the Rails application using the following configuration: server { listen 80 default_server; listen [::]:80 default_server ipv6only=on; server_name mydomain.com; root /var/www/html/wordpress; index index.php index.html error_page 500 502 503 504 404 @rails; location / { try_files $uri $uri/ /index.php?$args; recursive_error_pages on; error_page 404 = @rails; } location ~ \.php$ { fastcgi_pass unix:/run/php/php7.0-fpm.sock; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_intercept_errors on; include fastcgi_params; error_page 404 = @rails; } location @rails{ passenger_enabled on; passenger_user stephen; rails_env development; root /home/user/rails_app/app/public; } } The problem now comes when the rails app references any /assets links they always forward back into the rails app and always load the root location of the application. Is there any way to fix this so that assets will also be treated as part of the rails application?

In Rails, Ajax sorting can't' keep up with User moving items around in my list Posted: 30 Jul 2016 06:56 AM PDT In my rails app I've made a list that allows the user to sort records by click/drag/dropping them to reorder. After each reorder I run the update action and pass along the old_index and new_index of the item moved and reorder the entire list. The application works as would expected as long as I don't reorder items at a very fast pace. My question is how can I improve the design I have to account for a quick paced sorting by the user and reflect those changes accurately? Also I'm trying to prevent the user from having to click a "Save" button -- however if it is necessary then I can implement that. update action def update if @list_item.present? # update the modified item, and then update all items after that are affected old_index = params[:old_rank].to_i new_index = params[:sequence_rank].to_i @list_item.update(sequence_rank: new_index) # update the moved item # move element down and shift others up if old_index < new_index @list.list_items.where('sequence_rank <= (?) AND list_items.id \ <> (?) AND sequence_rank > (?)', new_index, @list_item.id, 0) .each_with_index do |item,index| item.update(sequence_rank: item.sequence_rank-1) end # move element up and shift elements down else @list.list_items.where('sequence_rank >= (?) AND list_items.id \ <> (?) AND sequence_rank < (?)', new_index, @list_item.id, old_index+1) .each_with_index do |item,index| item.update(sequence_rank: item.sequence_rank+1) end end end render nothing: true end Also I'm using the following gem: https://github.com/scttdavs/sortable-rails

scroll bar with Lazy Highcharts Posted: 30 Jul 2016 05:30 AM PDT Hi I am relatively new to rails and I am trying to implement a horizontal scrollbar using the lazy highcharts gem. So far I am having trouble getting the scrollbar to work, any suggestions on what I am doing wrong/leaving out? Controller: @logsChart = LazyHighCharts::HighChart.new('graph') do |f| f.series(:name=>'Session 2',:data=> [0, 20, 3, 5, 4, 10, 12 ]) f.series(:name=>'Session 1',:data=>[1, 3, 4, 3, 3, 5,4,-46,2,3,2,1,5,6,7,3,2,4,3,5,7] ) f.title({ :text=>"Load per Session"}) f.xAxis( min: 0, max:12, labels: {overflow: 'justify'}) f.scrollbar(enabled: true) f.options[:chart][:defaultSeriesType] = "column" f.plot_options({:column=>{:stacking=>"percent"}}) end View: <%= high_chart("my_id", @logsChart) %> Gemfile: gem 'lazy_high_charts', '1.5.0' gem 'highstock-rails' application.js: //= require highcharts //= require exporting //= require highcharts/highcharts //= require highcharts/highcharts-more //= require highcharts/highstock

How do I display all attributes from a rails select statement? Posted: 30 Jul 2016 06:36 AM PDT Please would it be possible to know how to display the :user_id, :player_id and :amount attributes together in a hash from the below code? At the moment the array created returns player_id as the key and amount as the value {1695=>100, 1714=>200} whereas I need something like {1695=>{:user_id,100}? The code in the controller is as follows: @duplicates = Bid.select(:player_id, :user_id, :amount).group(:player_id).having("count(*) > 1").maximum(:amount) The code in the view: <div class="col-sm-3" style="background-color:white;"> <%= @duplicates %><br> </div>

How can I use the normal radio buttons in react? Posted: 30 Jul 2016 03:53 AM PDT I am developing a webapp which uses materializecss, react along with ruby on rails.

Rails 4 - 2 word model names Posted: 30 Jul 2016 03:43 AM PDT I'm using rails 4 with pundit and with statesman. In each case, my pundit policy and my statesman model files don't work where the model name attached to them has two words. For example, I have a model called organisation_request.rb I have setup a pundit OrganisationRequestPolicy (in the same way I have set up every other pundit policy that applies to a model with a single word model name) and a state_tranistions file OrganisationRequestTransition (organisation_request_transition). The pundit/statesman files don't work. The only difference I can see is that the model name has two words. Is there a special convention for working with two word model names with these gems?

Capistrano deployed the app but its not opening in browser Posted: 30 Jul 2016 02:56 AM PDT I've a rails app that I'm trying to upload to a Digital Ocean (DO)'s droplet using capistrano, nginx and puma. I followed the tutorial in this link https://www.digitalocean.com/community/tutorials/deploying-a-rails-app-on-ubuntu-14-04-with-capistrano-nginx-and-puma and got the deployment part of the app to work. I didn't change much in my configuration files else than app name or changing server name in nginx.conf file to my droplet's ip. On deployment puma server starts. The trace messages are following: Execute puma:start 04:35 puma:start using conf file /home/root/apps/lixerr/shared/puma.rb 01 /usr/local/rvm/bin/rvm default do bundle exec puma -C /home/root/apps/lixerr/shared/puma.rb --daemon 01 RVM used your Gemfile for selecting Ruby, it is all fine - Heroku does that too, 01 01 you can ignore these warnings with 'rvm rvmrc warning ignore /home/root/apps/lixerr/current/Gemfile'. 01 01 To ignore the warning for all files run 'rvm rvmrc warning ignore allGemfiles'. 01 01 01 01 Puma starting in single mode... 01 01 * Version 3.6.0 (ruby 2.3.0-p0), codename: Sleepy Sunday Serenity 01 01 * Min threads: 4, max threads: 16 01 01 * Environment: production 01 01 * Daemonizing... 01 ✔ 01 root@138.68.3.74 1.441s I checked the log files on my droplet, puma starts w/o showing any error messages. Moreever I also symlinked the nginx.conf to the sites-enabled directory and sites-available directory using: sudo ln -nfs "/home/deploy/apps/appname/current/config/nginx.conf" "/etc/nginx/sites-enabled/appname" which they have mentioned at the end of the tutorial. Nginx is installed on droplet and I did not forget restarting it after creating the link. Still whenever I try to connect to droplet using its ip at http://138.68.3.74/ I get the following error in chrome: This site can't be reached 138.68.3.74 refused to connect. ERR_CONNECTION_REFUSED I've been working on it since last day and can't get it to work. I've no idea what am I missing. EDIT 1: The log files of nginx in /var/log/nginx directory show nothing at all.

Here is the users_controller: def create @user = User.create(user_params) respond_to do |format| if @user.save format.html { redirect_to users_path } format.json { head :no_content } else format.html { render :new } format.json { render @user.errors, status: :unprocessable_entity } end end end def edit end def update respond_to do |format| if @user.update(user_params) format.html { redirect_to users_path } format.json { head :no_content } else format.html { render :edit } format.json { render @user.errors, status: :unprocessable_entity } end end end and this is my form : <%= form_for @user do |f| %> # Here go fields for username, email and password <p> <%= f.label "Set as administrator" %> <br /> <%= f.hidden_field :admin, '' %> # I also tried with <%= f.hidden_field :admin, false %> <%= f.check_box :admin, checked = true %> # Or <%= f.check_box :admin, data: { switch: true } %> </p> <% end %> But any of these options returns me the following: NoMethodError in Multiflora::Users#edit undefined method `merge' for "":String What have I done wrong?

Rails 4 - Mini_Magick doesn't work with images - don't see any resized pictures Posted: 30 Jul 2016 05:33 AM PDT I'm using Rails 4 + Carrierwave + Mini_Magick for image processing. In my catalog all thumbnails are not displayed - "version :thumb" don't work. In rails server log I see many routing errors like that: Started GET "/uploads/item_image/image/57/thumb_testfile2.jpg" for ::1 at 2016-07-30 12:01:56 +0300 ActionController::RoutingError (No route matches [GET] "/uploads/item_image/image/57/thumb_testfile2.jpg"): When I change view partial from ... = image_tag item.item_images.first.image.thumb.url to ... = image_tag item.item_images.first.image.url fullsize images appear for all items! How to fix that? UPDATE Mini_magick works only for pictures uploaded through form_for. When I upload items through my import-script - thumbs not generate code from my import script: folder="tmp/c_pics/" path=folder + filename new_image=ItemImage.new new_image.image = Rails.root.join(path).open new_image.save! curr_item.item_images << new_image curr_item.save!

Rendering another controllers action as a partial from another view in Rails Posted: 30 Jul 2016 07:28 AM PDT I am trying to render a partial (e.g in controllerA) from another controller (e.g controllerB), in my view. The partial is rendering correctly with static content but when trying to access an instance variable, it fails. The instance variable is instantiated by an action in controllerB but this action is never called when simply rendering the partial. Is there a way to call an action before rendering the partial?

PG::InsufficientPrivilege: ERROR: must be owner of database Posted: 30 Jul 2016 01:36 AM PDT Good morning! Faced with the problem that when you run the tests, swears that the error with the database owner, but just before given privileges to the user at the database with the tests, please tell me where to dig. The test itself takes place, but before it pops up this error, username and database match the settings in the database.yml I found a similar article, but I have another error, and this decision does not apply: ActiveRecord::StatementInvalid: PG::Error: ERROR: must be owner of database Error Code: PG :: InsufficientPrivilege: ERROR: must be owner of database test System: Rails: 5.0.0 Ruby: 2.3.1 PSQL: 9.5.3

String.gsub in Ruby messing up the replacement? Posted: 30 Jul 2016 04:22 AM PDT This is a very unusual issue for me coming from JS background. I'm simply trying to replace a part of the page with external content on the fly. Here is the source.html: <!DOCTYPE html> <html> <head> <%= foobar %> </head> <body> This is body </body> </html> And a replacement string inject.js: var REGEXP = /^\'$/i; var foo = 1; Finally a ruby code that spits the output file by combining both. pageContent = File.read('./source.html') jsContent = File.read('./inject.js'); output = pageContent.gsub("<%= foobar %>", jsContent) File.open('./dest.html', "w+") do |f| f.write(output) end However, I get the messed up dest.html which is happening because of \' in inject.js. <!DOCTYPE html> <html> <head> var REGEXP = /^ </head> <body> This is body </body> </html>$/i; var foo = 1; </head> <body> This is body </body> </html> How do I get rid of this naive issue?

Rails will_paginate with named scope for associations > 0 Posted: 30 Jul 2016 01:30 AM PDT Similar to will_paginate with named_scopes but not getting an error - rather unexpected results. Rails version 4. If I have a scope in a Foo model (where a user has_many: foos) - models/foo.rb: belongs_to :user scope :hasCars, -> { joins(:cars) } And now try use the scope with will_paginate (in the controller): @foos = auser.foos.hasCars.paginate(:page=>1,:per_page=>20) Then the view duplicates each foo by the number of cars they have in the :through ownership association - so for foo 1 - 4 of a given user: foo1.cars.size # =>1 foo2.cars.size # =>4 foo3.cars.size # =>0 foo4.cars.size # =>2 View: foo1 foo2 foo2 foo2 foo2 foo4 foo4 Works as expected without the paginate and paginate works fine without the scope. The association of Foo to cars is :through => :ownership. I guess it's to do with the way the scope is created using a join and how that join is passed to will_paginate. This is the query I see in the logs: SELECT "".* FROM "foos" INNER JOIN "ownership" ON "ownership"."foo_id" = "foos"."id" INNER JOIN "cars" ON "car"."id" = "ownership"."car_id" WHERE "foos"."user_id" = ? [["user_id", 1]] This should return the correct number of rows. But then for each car owned by Foo, I see a query cars from cars where foo_id = X being duplicated, am guessing from a query generated by will_paginate Is there a better way to create the scope? Or should will_paginate be set up differently? Or could this be a will_paginate bug? I have tried using joins(:ownership) too in the scope - same behaviour.

Make a copy of tenant in apartment gem Posted: 30 Jul 2016 01:21 AM PDT I am using apartment gem with PostgreSQL and I need to make a copy of already existing tenant with data. One way which I can think of one way is to collect all data from the tenant and then switch tenant and start creating record below is a small demonstration.models are the list of models to be copied over. Apartment::Tenant.switch!('destination') models.each do |modal| eval("@#{modal.downcase} = #{modal}.all.collect{ |p| p.to_dh }") end Apartment::Tenant.switch!('target') models.each do |modal| eval("@#{modal.downcase}.each{ |p| #{modal}.create(p[:attributes], :without_protection => true) rescue p[:id]}") end models.each do |modal| ActiveRecord::Base.connection.reset_pk_sequence!(eval("#{modal}.table_name")) end Any help will be greatly appreciated.

Struggling to optimize rails WHERE NOT IN query in Rails Posted: 30 Jul 2016 06:38 AM PDT Here's the query as it is in rails: User.limit(20). where.not(id: to_skip, number_of_photos: 0). where(age: @user.seeking_age_min..@user.seeking_age_max). tagged_with(@user.seeking_traits, on: :trait, any: true). tagged_with(@user.seeking_gender, on: :trait, any: true).ids And here's the output of EXPLAIN ANALYZE. Note the id <> ALL(...) part is shortened. There are around 10K ids in it.

It seems like there's something wrong with Index Scan using users_pkey on users where the index scan is taking a very long time. Even though there's an index on age, number_of_photos and the id: add_index "users", ["age"], name: "index_users_on_age", using: :btree add_index "users", ["number_of_photos"], name: "index_users_on_number_of_photos", using: :btree to_skip is an array of user ids to not skip. A user has many skips. Each skip has a partner_id. So to fetch to_skip I'm doing: to_skip = @user.skips.pluck(:partner_id) I tried to isolate the query to just: sql = User.limit(20). where.not(id: to_skip, number_of_photos: 0). where(age: @user.seeking_age_min..@user.seeking_age_max).to_sql And still getting the same problem with the explain analyze. Again, list of user ids is snipped: Limit (cost=0.00..435.34 rows=20 width=1698) (actual time=0.219..4.844 rows=20 loops=1) -> Seq Scan on users (cost=0.00..819629.38 rows=37655 width=1698) (actual time=0.217..4.838 rows=20 loops=1) Filter: ((id IS NOT NULL) AND (number_of_photos <> 0) AND (age >= 18) AND (age <= 99) AND (id <> ALL ('{7066,7065,...,15624,23254}'::integer[]))) Rows Removed by Filter: 6 Total runtime: 5.044 ms Complete version here. Any thoughts on how I can optimize this query in rails + postgres?
