| Rails: DRYing up before_action Posted: 15 Mar 2016 06:53 AM PDT I have a few controllers: class First < ApplicationController before_action: do_this before_action: do_this_too end class Second < ApplicationController before_action: do_this before_action: do_this_too end class Third < ApplicationController end
Two of the controllers have the same before_action's method. How do I dry up this code so that the First and Second class use the before_action in one location but not the Third class? I am thinking of some kind of class inheritance solution. Any ideas? In my real world example I have more classes with multiple identical before_actions on each? |
| private_pub with Puma on heroku Posted: 15 Mar 2016 06:42 AM PDT I'm trying to deploy my production app on Heroku. I'm using both private_pub and Puma in my app. I wanted to start both using this procfile : web: bundle exec puma -C config/puma.rb web: bundle exec rackup private_pub.ru -s thin -p $PORT -E production
But it fails, it seems like you can have only one web process running at a time on Heroku apps. Is there a way to initialize both ? |

| How to create controller spec to test unauthorized access, redirect and message Posted: 15 Mar 2016 06:27 AM PDT I am trying to create controller specs, in this case for a user who is not authorized to access this resource. I need to detect the status, location of redirect, and message from Devise/ Cancan. After much hacking away, I came up with this. context 'with unauthorized user' do describe 'GET #index' do subject { xhr :get, :index, {} } it { subject; response.status.should eq 401 } #successfully detects unauthorized it { should redirect_to new_user_session_path } #Expected response to be a <redirect>, but was <401> it 'redirects' do get :index, {} expect(response).to redirect_to(new_user_session_path) #successfully detects redirect # how to get the Devise message? end end end
Could someone please help me to understand what is happening here. - What is the difference between
xhr :get, :index and get :index, {}. - What is the difference between
subject; response.status.should eq 401 and `response.status.should eq 401' - How to I get the message from the response?

| Why assert_select is not accepting parameters rails 4.2? Posted: 15 Mar 2016 06:05 AM PDT I am working on rails integration tests, someone wrote tests that were passing at that time but now they are giving warning here is the line of code i was working on assert_select "a[href=/monster_xml_users/#{user_xml.id}][data-method=delete]", I18n.t('revoke_access')
But now it is giving warning Invalid CSS selector, Assertion not run But if i write it alternatively like this assert_select "a", I18n.t('revoke_access') assert_select "a" do assert_select "[href=?]","/monster_xml_users/#{user_xml.id}" assert_select "[data-method=?]", "delete" end
Then it gives no warning and tests pass and it is correct. But i am unable to figure out why previous assertion is failing now ? Has assert_select syntax is changed now in Rails 4.2 ? |

| How to pass currently signed in user id to resolve block in ui-router state? (AngularJS) Posted: 15 Mar 2016 05:50 AM PDT I'm trying to pass the currently signed-in user to the resolve block of a 'user' state (I'm using ui-router), so upon sign-in, user will be in url of .../users/:id. Other routes are nested inside :user route, so this seems the most logical path to me (I may be wrong). I'm using angular_devise here so i should be able to extract the :id from from API via Auth, but I'm running into some trouble. (Included other possible relevant files below.) App.js $stateProvder .state('users', { url: '/users/{id}', templateUrl: 'home/_home.html', controller: 'MainCtrl', resolve: { userPromise: ['$stateParams', 'users', 'Auth', function($stateParams, users, Auth) { return users.get( Auth.currentUser().then(function (user) { return user.id; }) ); }] } })
Users.js .factory('users', ['$http', function($http) { var u = { userArray: [] }; u.get = function(id) { return $http.get('/users/' + id + '.json').then(function(res) { console.log('request: ', res.data); angular.copy(res.data, u.userArray); }); }; return u; }]);
Users_controller.rb class UsersController < ApplicationController def show @user = User.find(params[:id]) authorize @user respond_with @user end end
NavCtrl.js .controller('NavCtrl', [ '$scope', 'Auth', function($scope, Auth) { $scope.signedIn = Auth.isAuthenticated; $scope.logout = Auth.logout; Auth.currentUser().then(function (user) { $scope.user = user; }); $scope.$on('devise:new-registration', function (e, user) { $scope.user = user; }); $scope.$on('devise:login', function (e, user) { $scope.user = user; }); $scope.$on('devise:logout', function (e, user) { $scope.user = {}; }); }]) ;
FYI. $http request is being sent to a rails backend. I would be very grateful if anyone can advise what i might be doing wrong. |

| Form not updating Database with Select Tag Ruby Posted: 15 Mar 2016 05:51 AM PDT I have recently added a new column to my table in the database called "sport". I am trying to update the value in the column using a select_tag in a form however everytime I have tried the data has not updated. The rest of the form is currently working and updating correctly. The select tag is currently implemented like this inside my view. <%= f.label :sport %> <%= select_tag(:sport, options_for_select([['Basketball', 1], ['NRL', 2], ['Super Rugby', 3], ['AFL', 4], ['eSports', 5], ['Ice Hockey', 6], ['Horse Racing', 7], ['Tennis', 8], ['NFL', 9] ]))%>
:sport is declared as an integer within the table. The controller currently looks like this: class BetsController < ApplicationController def new @bet = Bet.new end def create @bets = Bet.new(bet_params) if @bets.save flash[:success] = 'Bet Successfull Logged.' redirect_to new_bet_path else flash[:danger] = 'Error, Bet has not been logged.

| Rails logger level changes to ERROR abruptly Posted: 15 Mar 2016 04:53 AM PDT I am experiencing very strange behavior with my Rails logs. Wherein the logger level automatically/abruptly changes to ERROR(:error. logger level code 3) instead of whatever it was supposed to be (:debug or :info). Here in this image the log level is as expected. Debug or level 0 
But within few minutes(at most 2 minutes) the logger level changes to 3(3 stands for ERROR) 
I came across a github issue which explains Rails logger is not thread safe, I am using passenger in thread mode as opposed to process which it was previously. Could this be a reason for such behavior ? What could be other possibilities, that changes the logger level from 0 to 3 ? |

| Rails admin panel loading slow Posted: 15 Mar 2016 04:23 AM PDT I am currently working on rails project with Mongoid ORM. I am using Rails admin gem for data handling at server side. Rails version is 4.1.7, Ruby is 2.1.5. Problem is it takes lot of time to load when admin panel is loaded the first time. I checked the logs of rails.

| Image change between view templates stopping onclick dropdown menu? Posted: 15 Mar 2016 04:49 AM PDT I placed an onclick dropdown menu in my top navigation bar. In the top navigation bar, I wanted to change this image in my new.html.erb view template: <li class="navigation-bar-right"> <span class="create"> <%= link_to image_tag("createpost.svg"),new_post_url, method: :get %> </span> </li>

| Creating rails new app takes too long Posted: 15 Mar 2016 04:40 AM PDT I'm new to Ror and I'm facing a problem while creating new rails app by using this command: $ rails new test_app it takes so long to execute it in bundle install process Ps.

| Use cookies.signed[:user_id] in capybara tests Posted: 15 Mar 2016 04:28 AM PDT I have this code to authenticate channel subscribers: module ApplicationCable class Connection < ActionCable::Connection::Base identified_by :current_user def connect self.current_user = find_verified_user end protected def find_verified_user if current_user = User.find_by(id: cookies.signed[:user_id]) current_user else reject_unauthorized_connection end end end end
And everything works fine. The problem is in feature tests. When I run this test: require 'rails_helper' feature 'Chat room' do scenario "send one message" do user = create(:user) login_as(user, :scope => :user) expect { fill_in 'message', with: 'hello friend' click_button 'Send' byebug }.to change(Message, :count).by(1) expect(current_path).to eq root_path expect(page).to have_content 'hello friend' end end
The test log, says that the "An unauthorized connection attempt was rejected". Since the cookie is empty, it is not able to authenticate. So how can I set the cookies in capybara tests? I tried something do this cookies.signed[:user_id] = user.id in the test but it does not work. How can I set the cookie like this cookies.signed[:user_id] = user.id in tests? |
| Generating PDF out of HTML template using flying_ruby_saucer gem in rails Posted: 15 Mar 2016 05:26 AM PDT My requirement is I am generating PDF out of the pre-rendered HTML template. This template is a multi-lingual page and uses custom fonts from our clients. Following approaches tried: I used wicked_pdf (internally uses wkhtmltopdf-binary) gem to achieve this, but the issues I face are: font kerning arent proper as every other character get overlapped on other. The same font appears proper on actual PDF. I included all CSSes directly into the HEAD -> STYLE, tried various tricks by setting letter-spacing, etc. but nothing worked. So, now using flying_ruby_saucer. Font kerning looks proper. But neither characters from Arabic OR HINDI is printed on PDF nor custom font is picked up. I have declared custom font as: @font-face { font-family: 'My Font'; src: url('http://localhost:3000/assets/MyFont.ttf'); } body{ font-family:"My Font"; }
But this doesnot work either as PDF generated shows default font family. Non-ascii characters arent printed too. Could anyone please help me fixing this (include foreign characters as well as include custom fonts)? Thanks. |
