Active Record doesn't update collection when there is joins and includes in query Posted: 19 Nov 2016 07:14 AM PST Hello I've a problem with my query. There are my models below: class Owner has_many :busiensses has_many :adverts end class Business belongs_to :owner end class Advert belongs_to :owner end When I make this query everything is okay and it returns right collection full of needed objects: Owner.joins(:adverts).includes(:businesses) .where(businesses: {owner_id: nil}) But when I add to query update it raises error Owner.joins(:adverts).includes(:businesses) .where(businesses: {owner_id: nil}) .update_all(status: 'sth') Error: ActiveRecord::StatementInvalid: PG::UndefinedTable: ERROR: missing FROM-clause entry for table "businesses" Where is the problem? I bet this error from SQL and it raised when you forget add sth to FROM statement and that sth needed in further conditions, but where in AR i forgot to add it?

Ember Js-Receiving Image From User Posted: 19 Nov 2016 06:57 AM PST In rails, since we can upload images with a form using gems like paperclip and carrierwave, and then resize them, how do i do same thing while using rails only for backend to an Ember Js app? TL;DR is, i have an Ember+Rails app.How do i receive image from user and resize it later?

Ruby on Rails foreign key field cannot be null Posted: 19 Nov 2016 06:32 AM PST I have a Rails application where there is a User model and a Role model. Role can be either Superuser, Admin or User. My Users table migration looks like this: class CreateUsers < ActiveRecord::Migration[5.0] def change create_table :users do |t| t.string :first_name t.string :last_name t.string :username t.string :email t.string :password t.string :password_digest t.boolean :banned t.references :role, foreign_key: true t.timestamps end end end Whenever I go to create my user using HTTP POST, I keep getting the error: Role must exist Which is Rails telling me the field role for my User model cannot be null. So I thought, well, I want my user created through HTTP POST to default to "User" role, so I have this in my User model: class User < ApplicationRecord belongs_to :role has_secure_password # validates :role, allow_nil: true before_validation do self.banned = false # Users created through HTTP POST request should always # default to 'User' role. # Rails console created users will be explicitly set # to 'Superuser' or 'Admin' roles. self.role = Role.find_by({title: 'User'}) puts "User model set role fired!" end end This fixes the errors but now I have a problem. When an admin user tries to change an existing user's role from "User" to "Admin", the before_validation method always fires, forever overwriting my POST params to specify new role for user. In effect, I can never change the role of any users. Am I doing something wrong? Surely there's a way to create a user without any roles assigned at the start and then set the role later... I've been scratching my head for hours.

How to group by first created_at? Posted: 19 Nov 2016 05:53 AM PST I have a model called Posts which are created by Users. Each post has a created_at attribute. I'd like to figure out how many users posted for the very first time on each date from a start-date to an end-date. I'm trying to get a result like this: 1/1/2016: 15 posted for the first time 2/1/2016: 4 posted for the first time 3/1/2016: 0 posted for the first time ... What's the best way to do this efficiently with ActiveRecord? :)

Rails - How can I avoid using the database while performing a detect method? Posted: 19 Nov 2016 06:55 AM PST When performing detect on a int array, it works: @number = [1,2,3,4,5,6,7].detect{|n| n == 4} Variable @number becomes 4. But when I do something like this: @categories = Category.all @current_category = @categories.detect{|cat| cat.id == params[:category]} The program outputs Category Load (0.2ms) SELECT "categories".* FROM "categories" Which means it's using the database to find it. However, the element I'm trying to find is already in the collection @categories, I just want to find it to assign it to a variable. Of course another solution would be to implement a linear search algorithm, but I just want to keep the code as clean as possible. How can I avoid using the database for this search? EDIT: I just realized that this could be lazy fetching. Because before detect, I never use @categories, so it does the query when I do detect. Could this be true?

Rails getting data from another table Posted: 19 Nov 2016 05:02 AM PST app/models/road.rb class Road < ActiveRecord::Base has_many :segments end app/models/segment.rb class Segment < ActiveRecord::Base belongs_to :road end app/controllers/welcome_controller.rb @segments = Segment.joins(:road).select("segments.id, segments.name, segments.road_id, roads.name AS roadname, ST_AsGeoJson(segments.geom) AS segment_geom") app/views/welcome/index.html.erb <script> <% @segments.each do |segment| %> var segment<%= segment.id %> = new L.geoJson((<%= segment.segment_geom.to_s.html_safe %>), {style: statesegmentStyle}) .bindPopup('id: <%= segment.id %><br>road_name: <%= roadname %>').addTo(segments); <% end %> <script> when reload the page I get this: undefined local variable or method `roadname' for #<#<Class:0x00000003a14ef8>:0x007f7ea4628d90>

Ecommerce store customization using Spree Posted: 19 Nov 2016 04:57 AM PST I am building an ecommerce store using Spreecommerce to sell some merchandise. In addition to the "shop" where I have all the products listed, I also need a way for users to pay for the conferences that I'll be hosting. So, if a user clicks on "Participate" on one of the conference in conferences page, they are redirected to the cart page with that conference added in their cart. I need to understand the best way to acheive something like this. Should I create "conferences" as products and give them some special taxonomy so that they are not visible in the listings page? What is the best approach to do this? Should I create a separate conferences model and integrate it with cart?

Multiple select in administrate Posted: 19 Nov 2016 04:31 AM PST Since administrate does not yet have support for multiple selects. Has anyone created a custom multiple select? Preferably one that works like the HasMany select.

Rendering HTML instead of JSON: Ruby on Rails Posted: 19 Nov 2016 07:49 AM PST I have an API that I am trying to call from a method within my application. Even though I am calling the API using the json format, and I am setting the respond_to to JSON, it still renders as HTML. This is the method in the controller: def index @moviedetails = Moviedetail.all respond_to :json end This is the API call from the method def self.searchHighestRating() url="https://ruby-rsudding.c9users.io/moviedetails.json" response = HTTParty.get(url) responsebody = JSON.parse(response.body) return responsebody end Any thoughts around how I could resolve this?

OAuth with a non-gemified strategy service provider Posted: 19 Nov 2016 03:06 AM PST So I am building an application where users can login with a service provider that does not provide a gemified OAuth strategy. They provide me the necessary steps (and corresponding URLs) necessary to authenticate the user (here). However, I am not sure what is the best approach to include it in a rails application. I've already done user authentication with Facebook (with the gemified OAuth strategy provided by facebook) and it was very straightforward. Although, this is different. I'v also tried to write a OAuth strategy by I am not sure what to write on client options (Facebook example here). Can anyone help me? thanks

Very slow Sprockets in Rails 4 development environment: what's wrong? Posted: 19 Nov 2016 02:39 AM PST I've been banging my head over this for some time. Our project has grown to a reasonable size: approx. 250 JS files and 50 SASS files. Not too excessive, I would say. Still, Sprockets is taking a very long time to render all the assets. Even on simple page reloads, where I would expect to see some benefits of caching, it takes seconds to 10, 20, 30 and sometimes more seconds to serve all assets. And that's on a decent MacBook Pro with SSD. Here's a flamegraph of one of the simplest pages: the login page. That takes about 12 seconds to load. The "real" application pages are much worse: Setting config.assets.debug = false helps some, but at the same time, I would really love to keep it set to true for easier debugging. Does anyone have any suggestions of how to make this more workable?

Rails "Get" Url to query Mongo DB Posted: 19 Nov 2016 02:39 AM PST There are a controller and a Model both named by 'Article'. and I want to query the data in Mongo DB by passing the argument in the url. e.g. http://localhost:3000/articles/?category.newsCat=UNCATEGORISED By the above, I'd like the rails to show the Articles by category.newsCat=UNCATEGORISED. Thanks.

Sengrid modifies links inside email and they dont redirect to correct page Posted: 19 Nov 2016 02:17 AM PST I have a rails app running in production with sengrid. At one point in my app I am sending an email with a confirmation link which redirects to a specific confirmation page : %a.button.button-custom.button-blue{href: confirm_votes_path(@vote.confirmation_token, only_path: false) However in production, Sengrid seems to modify the link inside my mails. I get something like : href="https://u3881616.ct.sendgrid.net/wf/click?upn=pVistOUxWTXmIPFqqAw0AnJt-2BbCLbreZ3xbCIcCjU0qXsxlkph8Wd3VafON-2FVyJfT0PWClbesX-2F2oOjnxeXwwaDA80aCKixoULvRGUX7PgDg59Vde4HU6spxlzuqyUUF_e4qGN2gUHpERWs59wU8LHyeuQCdWWdC4Yjpw10HvUcUonj0ZfIp-2FiYACT83qOqsHMBnkJGcBsjpIoSUjVySxVhEtqCz7myXFB-2B7uTWKruQbH-2BG7-2FI2-2BFdmXC6nbf-2FFpgyNUivvir0Upib8e5r8YJY3caF-2BpKD-2FscuINwBQkM7n008mEGADo5w5w5fejlzhopGHvJegbSRePJ-2BBu3b3olUhP2q-2BX4lyJAYvegG4xnDPU-3D" and the link redirects to the base url of my website and not the good confirmation url like it does locally.

Ruby on Rails: Checkbox gets unchecked when trying to edit a post Posted: 19 Nov 2016 05:25 AM PST When i create a new post (passengerride), it is successfully storing multiple value in database. But, when i try to edit the post (passengerride), the checkboxes are getting unchecked. This is my form: apps/views/passengerrides/_form.html.erb: <%= form_for @passengerride do |f| %> ...... <div class="form-group "> <div class="control-label col-sm-2 requiredField"> <%= f.label :okwithgender, 'Driver should be:' %> <span class="asteriskField">*</span> </div> <div class="col-sm-8"> <div class=" "> <div class="checkbox"> <label class="checkbox"><input id="okwithgender" type="checkbox" value="Male" name="passengerride[okwithgender][]">Male</label> </div> <div class="checkbox"> <label class="checkbox"><input id="okwithgender" type="checkbox" value="Female" name="passengerride[okwithgender][]">Female</label> </div> <div class="checkbox"> <label class="checkbox"><input id="okwithgender" type="checkbox" value="Other" name="passengerride[okwithgender][]">Other</label> </div> <div class="checkbox"> <label class="checkbox"><input id="okwithgender" type="checkbox" value="Any Gender" name="passengerride[okwithgender][]">Any Gender</label> </div> </div> </div> </div> .... <% end %> app/controllers/passengerrides_controllers: def passengerride_params params[:passengerride][:okwithgender] = params[:passengerride][:okwithgender].join(', ') params.require(:passengerride).permit(:origin, :destination ... :okwithgender) end I guess using this <%= f.check_box ... %> will solve the problem, but i'm not sure how to write something equivalent to <input id="okwithgender" type="checkbox" value="Male" name="passengerride[okwithgender][]">

Why is this not the same code Posted: 19 Nov 2016 01:54 AM PST In my test I assure that two controller methods are called in a seperate helper class: controller.expects(:sign_in).with(user).returns(:ok) controller.expects(:redirect_to).returns(:ok) When my write my helper class like, that, the tests work as aspected and succeed: def call @controller = context.controller controller.sign_in user controller.redirect_to remove_from_url(url) end But when I change it to: def call @controller = context.controller controller do sign_in user redirect_to remove_from_url(url) end end Then the tests fail, as message I get: expected exactly once, not yet invoked ... Why does this code not do the same?Thanks 1) controller.sign_in user controller.redirect_to remove_from_url(url) 2) controller do sign_in user redirect_to remove_from_url(url) end

jQuery script for making checkbox appear based on if selected category contains true boolean Posted: 19 Nov 2016 12:47 AM PST I am trying to check if there is a boolean value of true within the subcategory I select in a dropdown which in turn would make a checkbox appear. In my form partial to create a new post I have to select a Category and a SubCategory accordingly. My SubCategories are seeded like so SubCategory.where(name: 'DB', service_type: true, category_id: 1_category.id).first_or_create. The current javascript I am trying to make work is $(document).ready(function () { $("#service-select").hide(); $('#subcategory-select').change(function () { var subcatServ = $(this).val(); $('#service-select').hide(); if (subcatServ === "Persons") { $('#service-select').show(); } }); }); #select-service is where the checkbox and #subcategory-select is the selected subcategory. I currently use this JS to make SubCategories and the associated ID appear and be saved when I select their parent Category: $(document).ready(function() { var subcat; subcat = $('#subcategory-select').html(); return $('#category-select').change(function() { var cat, options; cat = jQuery('#category-select').children('option').filter(':selected').text(); options = $(subcat).filter("optgroup[label='" + cat + "']").html(); if (options) { return $('#subcategory-select').html(options); } else { return $('#subcategory-select').empty(); } }); }); HTML: <%= form_for @post do |f| %> .... .... <p> <%= f.label :category_id%> <%= f.collection_select(:category_id, Category.all, :id, :name, { prompt: 'Select a category' }, { id: 'category-select' }) %> </p> <p> <%= f.label :subcategory_id%> <%= f.grouped_collection_select :subcategory_id, Category.all, :sub_categories, :name, :id, :name, { prompt: 'Select a sub category' }, { id: 'subcategory-select' } %> </p> <p> <%= f.label "checkbox"%> <%= f.check_box :serivce_type, id:'service_select' %> <!--work on--> <p> <%end%> I'm unsure on how to do this and have thought about and researched how for ~30mins, any help would be appreciated.

how pass url helper in model with :locale parameter? Posted: 19 Nov 2016 01:11 AM PST I need pass in charge attributes in model contract_url(contract) I have following code in model CheckoutService: delegate :url_helpers, to: 'Rails.application.routes' def contract_url(cont) url_helpers.contract_url(cont) end In charge_attributes i need set url for attribute secureUrl, for example: charge_attributes { secureReturnUrl: contract_url(contract) } I get an error: ActionController::UrlGenerationError: No route matches {:action=>"show", :controller=>"contracts", :locale=>#<Contract id: 13, ..} missing required keys: [:id] rake routes: contract GET (/:locale)/contracts/:id(.:format) contracts#show {:locale=>/en|fr/} PATCH (/:locale)/contracts/:id(.:format) If i call this url helper in controller or view work correct.

Rails: form_for with json: undefined method to_model for Hash Posted: 19 Nov 2016 07:24 AM PST Converted my site to use redis so a JSON array is sent to my views instead of an ActiveRecord array. Made all the necessary conversions like model.attribute to model['attribute']. However, can't figure out getting my form_for to work. User can make a prediction on a game. The same _form.html.erb is used to create or update the prediction. The error I get, undefined method 'to_model' for #<Hash:0x007ff28d5f19c8> occurs on both of these lines: _form.html.erb <%= form_for [game, (prediction || Prediction.new)], remote: true do |f| %> ... <%= link_to "Delete", [game, prediction], method: :delete, remote: true, class: 'btn btn-xs btn-danger' if prediction.present? %> Any ideas? If you need more info, read below: The link and partial: # index.html.erb @games.each do |game| ... <%= prediction_form_link(@predictions, game) %> <%= render partial: 'predictions/form', locals: { game: game, prediction: prediction_for(@predictions, game) } %> Basically, load partial with form and pass in game and prediction, but also determine whether prediction already exists to be updated instead of created: def prediction_for(predictions, game) predictions["#{game['id']}"].first if predictions["#{game['id']}"].present? end def prediction_form_link(predictions, game) if prediction = prediction_for(predictions, game) ... # code that displays what this button looks like. Partial is loaded in a modal. Thank you.

I got this test case here: test "user show - cannot show other user's info" do get user_path(@sarah), headers: user_authenticated_header(@jim) assert_raises(Pundit::NotAuthorizedError) end I ran my test, all the other ones passed, except this one which says: Error: UsersControllerTest#test_user_show_-_cannot_show_other_user's_info: Pundit::NotAuthorizedError: not allowed to show? Am I writing the assert_raise exception correctly? Why is my test not passing? It seems like once the error is raised, the next line in my test is not ran anymore.
