| Rails dropdown menu - assign parameter for path from the user's selection Posted: 18 Dec 2016 08:12 AM PST I want this form to appear as a dropdown list: <%= form_tag job_index_path do %> <%= select_tag "area", options_for_select(@areas.collect { |area| [ area.name, area.name ] }), :onchange => "this.form.submit();" %> <% end %>
The desired outcome is that when the form is submitted it will take the 'area' that the user select and add it as a params[:area] option for the following route: get ':area' => 'job#index', :as => 'job_index'
For example, if the list that has three options: London, Dublin, Paris. When the user selects 'Dublin', the form submits and assigns params[:area] to be 'Dublin'. It then goes to the URL localhost:3000/Dublin. However, I can't figure out how to add the :area parameter to the form path once the user makes their suggestion. I'm sure its probably a very easy thing to do, but I can't seem to figure it out. Any help is greatly appreciated :) |
| How to change the default routing of a model at root in rails? Posted: 18 Dec 2016 08:07 AM PST I am trying to change the controller and action of users model in routing.rb when pointed at /users url. Here is how I tried to change it: resources :users, only: :show do get 'favorites' => 'routers#client' get 'tours' => 'routers#client' get 'offers' => 'routers#client' get 'open_houses' => 'routers#client' get 'searches' end get 'users/:id' => 'routers#client'
The favorties, tours, offers and open_houses route to routers_controller client action when url such as /users/:id/favorites etc are called. But when calling the /user/:id, it doesn't map to routers controller. How should I change the index route to this controller? |

| Error with routing and headers in Ruby on Rails Posted: 18 Dec 2016 07:52 AM PST I'm with the following problem: I'm trying to create a route with a default format type as JSON: Rails.application.routes.draw do namespace :api, path: '/', constraints: { subdomain: 'api' } do namespace :v1 do resources :pessoas_fisicas, defaults: { format: 'json' } end end end
When I access the URL http://api.sistema-controle-contas.com:3000/v1/pessoas_fisicas, it shows the expected result, a JSON output. The controller that I'm using for this code is: def index @pessoas_fisicas = PessoaFisica.all respond_to do |format| format.json { render json: @pessoas_fisicas, status: 200 } format.xml { render xml: @pessoas_fisicas, status: 200 } end end
But It always return a JSON file, even if I send a header asking for a XML like this: $ curl -IH 'Accept: application/xml' 'http://api.sistema-controle-contas.com:3000/v1/pessoas_fisicas'
It returns: HTTP/1.1 200 OK X-Frame-Options: SAMEORIGIN X-XSS-Protection: 1; mode=block X-Content-Type-Options: nosniff Content-Type: application/json; charset=utf-8
If I took off the 'defaults: { format: 'json' }' from the route, the curl request return the XML expected. However, the application stops to work as it does not know the format that is needed to show. And on the Browser I got: "status": 406, "error": "Not Acceptable", "exception": "#<ActionController::UnknownFormat: ActionController::UnknownFormat>"
Could someone help with this, please? |

| Image_tag and turbolink Posted: 18 Dec 2016 06:15 AM PST I started my journey with Rails and Ruby a couple of days ago and so far it is going well and I'm loving it! Though, I do have a minor concern that I cannot find a solution to. I've had a minor sneak peek on turbolink and how that is embedded with Rails. But, my question (problem?) is that whenever I import/include an image (which is located in app/assets/image) with Rails image_tag(...), that image is reloaded whenever I redirect to another page. But if I use <img src="..." whereas the src is an extern link (image fetched from another page) it is not being re-fetched (meaning, it's cached when I redirect to another page). So my question is: is there a special way to apply turbolink to image_tag? Thanks. |

| What is the proper way to make an increment function work? Posted: 18 Dec 2016 04:57 AM PST I'm creating a website that let people read short stories in several chapters. For this, I nested a chapter scaffold inside a novel scaffold, and linked (novel has_many :chapters, chapters belongs_to :novel) them both together. However I'm trying to get the chapter's number inside the URL (instead of the id, which never decreases). Setting the chapter as is is not a problem, but I'd like to automate the chapter number without my users needing to add it themselves. To do so, I figured that all I needed was to get how many chapter the current novel had by checking self.class.where(:novel_id => @novel).count. At this point, I have no issues, however it gets complicated when I try to increment this number, I get the error: undefined method 'anoter_one' for 0:Fixnum Here is my "another_one" function inside my model (I tried some things) def another_one @number = self.class.where(:novel => @novel).count.to_i @number.increment end
Here is the controller def create @novel = Novel.find(params[:novel_id]) @chapter = Chapter.new(chapter_params) @chapter.chapter_number.another_one @chapter.novel = @novel if @chapter.save redirect_to novel_chapter_path(@novel, @chapter), notice: 'Chapter was successfully created.' else render :new end end
What am I doing wrong ? Thank you in advance |

| Configuring strong parameters for dynamic keys Posted: 18 Dec 2016 03:50 AM PST I'm attempting to provide a form that allows an admin to edit all values of a particular model Submission, almost as though it was a spreadsheet. Submission is comprised of one string field :domain. The problem is that I can't figure out how to deal with strong params within this context. I've found similar examples of dealing with dynamic keys like this one but I can't quite figure out how to apply them to my parameter structure. I think I'm just not clear enough on how tap works. Here's an example of my parameters: {"3"=>{"domain"=>"domain3"}, "2"=>{"domain"=>"domain2"}, "1"=>{"domain"=>"domain1"}
In case it helps, here's the form I'm using: <%= form_tag update_multiple_submissions_path, method: :put do %> <table data-toggle="table" data-sort-name = "domain" data-sort-order = "desc"> <thead> <th data-field="domain" data-sortable="true">Domain</th> </thead> <tbody> <% @submissions.each do |submission| %> <%= simple_fields_for "submissions[]", submission, defaults: {label: false} do |f| %> <tr> <td><%= submission.domain %><%= f.input :domain %></td> </tr> <% end %> <% end %> </tbody> <table> <%= submit_tag "Save" %> <% end %>
And in case you're curious, here's the update_multiple method from my controller. If this looks familiar, I got the outline from a railscast, which was very effective in rails3 before strong params was (were?) ubiquitous. def update_multiple logger.debug "update_multiple #{submission_params}" @submissions = Submission.update(submission_params[:submissions].keys, params[:submissions].values) flash[:notice] = "Updated Submissions" redirect_to review_submissions_path end
This works very well if I bypass strong prams altogether using params.permit! but, of course, this is an unacceptable solution. Thanks for any help! |
| "Expected string default value for `--jbuilder`; got true (boolean)" error in a new rails project Posted: 18 Dec 2016 05:48 AM PST I am starting a new project, and have done this meany times now. However, this is the first time I have run into this issue! I created the app as normal rails new myapp -d postgresql I've created the DB using rails db:create and ran the site rails s. It all works, and I see the Rails welcome/holding page. Now I start to create my models, rails g model user for example. And I get this! Expected string default value for `--jbuilder`; got true (boolean) invoke active_record The name 'User' is either already used in your application or reserved by Ruby on Rails. Please choose an alternative and run this generator again.
Ok that's fair enough, I understand the error message. So I thought I would try to create a different model. When I run rails g model testing, and I get... Running via Spring preloader in process 31815 Expected string default value for '--jbuilder'; got true (boolean) invoke active_record create db/migrate/20161217171019_create_testings.rb create app/models/testing.rb invoke test_unit create test/models/testing_test.rb create test/fixtures/testings.yml
Has anyone else had this issue and if so any ideas why? I have tried running bundle install and bundle update with no luck. I have also tried setting the thor version as mentioned in this post I am using Rails 5.0.0.1 and Ruby 2.3.1. I noticed this has only just started happening since I did an update to macOS to 10.12.1 I am not sure if they are related. Update So I started to test this out. And I created a couple of different projects 'rails new testapppg' and 'rails new testapp-pg'. On both of apps I changed the thor gem gem 'thor', '0.19.1'. I then went on to run bundle update, and create the DB. Now both of these projects created the test models when running rails g model sample Cool! So that is the fix. So I went back and recreated my pxl-insight app, updated the thor gem, created the DB. Now when I went to create the model I get the errors again!? So my next question is does Rails cache project names? which is why the new projects worked fine, but the one with the previously used name causes the error? |

| Using Ransack in rails for searching companies and associated categories Posted: 18 Dec 2016 12:17 AM PST I have a search feature in my app where I search for a company and the results are companies fitting the name and the associated primary_categories for all of those companies. I'm using ransack to grab the relevant companies. Companies and PrimaryCategories have a has_many_and_belongs_to_many association. I'm refactoring the code to grab relevant primary categories from returned companies. Below is the method before the changes. def search @q = Company.ransack(name_cont: params[:q][:name], keywords_name_cont: params[:q][:name], m: 'or') @companies = @q.result.uniq @q2 = PrimaryCategory.ransack(name_cont: params[:q][:name]) @categories = @q2.result.uniq @search_term = params[:q][:name] end
On the search results page, I can retrieve the company but the primary categories are blank since I'm being returned an empty array object. I'm looking for a clean way to extract the associated primary_categories from the returned companies I've re-written the above method to include an array object. def search @q = Company.ransack(name_cont: params[:q][:name], keywords_name_cont: params[:q][:name], m: 'or') @companies = @q.result.uniq @categories = [] @search_categories = @companies.each {|co| @categories << co.primary_categories} @categories.flatten!.uniq @search_term = params[:q][:name] end
This works but I want to know if I can get the same result using ransack. Is there a more efficient way to grab the associated objects using ransack instead of creating a separate categories array? |

The Renters model is working fine and similar code I have to make a new Renter is working so I am not sure what is wrong. |
| Rails 3: how to check if very large migration is running properly Posted: 18 Dec 2016 03:04 AM PST I want to update all of a column in a table with over 2.2 million rows where the attribute is set to null. There is a Users table and a Posts table. Even though there is a column for num_posts in User, only about 70,000 users have that number populated; otherwise I have to query the db like so: @num_posts = @user.posts.count
I need to use a migration to update the attributes and I'm not sure whether or not it's running properly. Here is my migration file: class UpdateNilPostCountInUsers < ActiveRecord::Migration def up nil_count = User.select(:id).where("num_posts IS NULL") nil_count.each do |user| user.update_attribute :num_posts, user.posts.count end end def down end end
In my console, I ran a query on the first 10 rows where num_posts was null, and then used puts for each user.posts.count . The total time was 85.3ms for 10 rows, for an avg of 8.53ms. 8.53ms*2.2million rows is about 5.25 hours, and that's without updating any attributes. How do I know if my migration is running as expected? Is there a way to log to the console %complete? I really don't want to wait 5+ hours to find out it didn't do anything. Much appreciated. |

| TurboLinks with Angular Posted: 17 Dec 2016 11:27 PM PST I'm running Angular 1.6 along with TurboLinks 5. For the most part, things are working well. I disabled TurboLinks cache and am manually bootstrapping Angular per some of the suggestions on this post: Using angularjs with turbolinks I have run into one issue though where I have an $interval running within a service. When changing pages via TurboLinks, Angular bootstraps again and the service creates a new interval, but the old one continues to run! Every time a page change event occurs, a new interval is created and they keep piling on top of each other. I tried destroying the angular app when a TurboLinks link is clicked (using the code below), but that seems to cause the whole Angular app to quit working. I also can't seem to get a reference to the older interval after a page reload. var app = angular.module('app', []); // Bootstrap Angular on TurboLinks Page Loads document.addEventListener('turbolinks:load', function() { console.log('Bootstrap Angular'); angular.bootstrap(document.body, ['app']); }); // Destroy the app before leaving -- Breaks angular on subsequent pages document.addEventListener('turbolinks:click', function() { console.log('Destroy Angular'); var $rootScope = app.run(['$rootScope', function($rootScope) { $rootScope.$destroy(); }]); });
Without the $rootScope.$destroy() on the turbolinks:click event, everything else appears to be working as expected. I know I could fire off an event here and kill the interval in the service, but ideally I'd like some way where this is automatically handled and ensured nothing is accidentally carried over between TurboLinks requests. Any ideas? |

| Rails 5 - Acts as Taggable On with predefined tags Posted: 17 Dec 2016 11:20 PM PST I'm trying to use the acts as taggable on gem with my rails 5 app. I have a model called Proposal, which I'm trying to tag with predefined tags from my Randd::Fields model. In my proposal.rb, I have: class Proposal < ApplicationRecord acts_as_taggable acts_as_taggable_on :randd_maturities, :randd_fields, :randd_purposes, :randd_activities
In my proposal controller, I have whitelisted the randd_fields_list attribute: params.require(:proposal).permit(:title, :randd_fields_list) In my Randd::Fields table, I have one record saved: Randd::Field.all Randd::Field Load (0.5ms) SELECT "randd_fields".* FROM "randd_fields" => #<ActiveRecord::Relation [#<Randd::Field id: 1, created_at: "2016-11-26 08:38:11", updated_at: "2016-11-26 08:38:11", anz_reference: "test ref", title: "test title">]>
In the console, I'm trying to add the predefined Randd::Field.title to the proposal: Proposal.first.randd_field_list.add(Randd::Field.find_by(id: 1).title) But - then when I try: Proposal.first.randd_field_list, I get: p.randd_field_list ActsAsTaggableOn::Tagging Load (0.7ms) SELECT "taggings".* FROM "taggings" WHERE "taggings"."taggable_id" = $1 AND "taggings"."taggable_type" = $2 [["taggable_id", 17], ["taggable_type", "Proposal"]] ActsAsTaggableOn::Tag Load (0.9ms) SELECT "tags".* FROM "tags" INNER JOIN "taggings" ON "tags"."id" = "taggings"."tag_id" WHERE "taggings"."taggable_id" = $1 AND "taggings"."taggable_type" = $2 AND (taggings.context = 'randd_fields' AND taggings.tagger_id IS NULL) [["taggable_id", 17], ["taggable_type", "Proposal"]] => []
So - that hasn't worked. How do I make the randd_field_list update with my defined tags in the Randd::Field table? |

| What is the correct syntax for @pin in the new method? Posted: 18 Dec 2016 04:14 AM PST I know that the correct syntax for @pin in create method is @pin = current_user.pins.build(pin_params), but I'm just not 100% sure which syntax to use in new method since it is just for initialization.
is it? def new @pin = Pin.new end
or is it? def new @pin = current_user.pins.build end

| How to get an item's rank in an ActiveRecord collection, with ties? Posted: 17 Dec 2016 09:29 PM PST I've got a collection of @players, ordered by total_points. I'm trying to figure out what position a specific @player is ranked in the collection of @players. Example: there are 5 players, here are their total_points: - Player 1: 20 points
- Player 2: 20 points
- Player 3: 15 points
- Player 4: 15 points
- Player 5: 15 points
Given that we measure ties like this: - Player 1: Tied for 1st
- Player 2: Tied for 1st
- Player 3: Tied for 3rd
- Player 4: Tied for 3rd
- Player 5: Tied for 3rd
What's the easiest way to only show Player 4's rank? Is this possible without iterating through the entire collection? I have an idea of how I would print out the entire list by checking if the previous iterator's total_score is the same, but I don't need to display the whole list, just the rank for the current player. In my app, there are going to be close to a thousand players, so I'm trying to find a method that will be fast to calculate. EDIT: Here's what I've come up with based on @max's answer: @grouped_players = Player.all.reorder(total_points: :desc).group(:total_points).count our_rank = 0 tied = false @grouped_players.each do |points, count| if points > @player.total_points our_rank += count end if points == @player.total_points our_rank += 1 if count > 1 tied = true end break end end puts our_rank puts tied
Anyone have a more elegant solution? |
| Rails query for a social network feed Posted: 18 Dec 2016 02:33 AM PST The architecture of the model is simple. class User < ActiveRecord::Base has_many :hunts, dependent: :destroy has_many :user_hunts, dependent: :destroy end class Hunt < ApplicationRecord belongs_to :user has_many :user_hunts, dependent: :destroy end class UserHunt < ApplicationRecord belongs_to :user belongs_to :hunt end
User can create hunts . Other Users can see these hunts in their feed. They can either accept it or reject it. This would create a row in UserHunt with hunt_id and user_id. So what I want is a result of Hunt which satisfy these onditions.
Hunt is not his own (hunt.user_id != id)User has not seen the hunt before ( This is the part which I am finding difficult to implement) After lot of trials this is what I came up with. Hunt.left_outer_joins(:user_hunts) .where('user_hunts.user_id != ? OR user_hunts.user_id is null AND hunts.user_id != ?',id,id)
But this has a problem of selecting hunts which other users have subscribed. This is a common scenario in websites I believe. But I was not able to find any solution here. Thanks in advance. |

| Rails 5 - Rake task to import data from CSV file Posted: 17 Dec 2016 10:41 PM PST I am trying to follow the GoRails tutorial for importing data from a csv file. In my rails app, I have saved the file as for_codes.csv. In my lib/tasks folder, I have made a file called: import.rake In my input.rake file, I have: require 'csv' namespace :import do desc "import research fields from csv" task rannd_fields: :environment do filename = File.join Rails.root, 'for_codes.csv' counter = 0 CSV.foreach(filename, headers: true) do | row | p row ["anz_reference"] for_code = Randd::Field.create(:anz_reference: row["anz_reference"], title: title) counter += 1 if randd_field.persisted? end puts "Imported #{counter} field codes" end end
When I then try this in the console, with: bundle exec rake import:randd_fields
I get an error that says: NameError: undefined local variable or method `randd_fields' for main:Object
The model I'm trying to make records on is called: class Randd::Field < ApplicationRecord
The table in the database is called: randd_fields
Can anyone see what I need to do to rake this task? |

I have no idea what this means. All I did was download a jekyll theme here: http://chalk.nielsenramon.com, change a few things in _config.yml (Just the twitter/github and profile usernames) and run jekyll serve command in my cmd. This is the error message that shows up. I haven't done jekyll very long, so I apologize |
| Rails Strong Params not recognizing params sent through Ajax Post Posted: 17 Dec 2016 06:52 PM PST Hello I am trying to sent the following params from the front end to my backend rails controller where I have strong params set up My ajax call looks like this $("#send").click(function() { var message = $("#message").val(); var listing_id = $("#listing_id").val(); d = { 'message': message, 'listing_id': listing_id, 'status': "pending" }; $.ajax({ type: "POST", url: "/crecits", data: d }); });
This is sending in the following parameter to the controller Parameters: {"message"=>"Hello world", "listing_id"=>"1", "status"=>"some status"}
And then my controller that handles this looks like this class CrecitsController < ApplicationController .. def create @crecit = current_user.crecits.new(crecits_params) respond_to do |format| if @crecit.save format.html { redirect_to @crecit, notice: 'Request Sent' } else format.html { redirect_to listings_path, notice: 'your request can not be sent' } end end end private def crecits_params params.require(:crecit).permit(:user_id, :status, :listing_id, :message) end .. end
