How do I get RSpec and Cucumber tests to run in an app using both Mongoid and ActiveRecord? Posted: 30 Dec 2016 07:25 AM PST My team's project is a Rails 4.2 app using Mongoid 4. A new feature we are adding requires us to read data from a Postgres DB and use those records in the app through an intermediary object. In other words, our app will play with ActiveModel objects (non-persisted) that contain a mix of data from Mongoid models and ActiveRecord models, and thus can do all the normal cool Rails stuff with Controllers and Views, etc. (We think it's clever.) The intention right now is that we will never write to the SQL tables, just read. Any new data stored will be in mongodb. For my development environment, the first steps seemed pretty straight-forward: I added pg to the gemfile I added require "active_record/railtie" to application.rb I made my new models in the normal ActiveRecord way (although since I was working with an existing database, I changed the class names to something more meaningful and set the table names accordingly) I added a database.yml file (we didn't need one with mongoid) with all the correct postgres info I created the schema.rb file using rake db:schema:dump. That took a while to figure out I needed it, but I got there. Using the rails console, I was able to prove to myself that I could search/find objects in both databases. So far so good. When I first fired up the rspec tests, there were tons of failures related to validation errors because "records already existed with that name". Long investigation story short, I fixed by setting all DatabaseCleaner calls to be DatabaseCleaner[:mongoid], and that got rspec passing again. (I still have no idea what was actually happening behind the scenes.) BUT, Cucumber (feature) tests? I can't even get them started. It keeps saying: Migrations are pending. To resolve this issue, run: bin/rake db:migrate RAILS_ENV=test No! All those migrations we have are for MONGO. There are no SQL/ActiveRecord migrations. Not surprisingly, that rake fails: rake aborted! ArgumentError: wrong number of arguments (2 for 0). I tried this series of commands: rake db:drop RAILS_ENV=test rake db:create RAILS_ENV=test rake db:schema:load RAILS_ENV=test but cucumber still gives the same migration pending error. So I'm stuck! I haven't found anyone doing what we're trying to do. I know there HAS to be someone, I just haven't found the right search terms, apparently. The worst part of all this is I had no intention of even using an ActiveRecord test database at all, I was simply going to mock those records in my tests. How can I tell the app, "I only need ActiveRecord for runtime, not testing. Stop looking at the migrations, ActiveRecord, those aren't for you!" I have run out of ideas and words to search with. I've been trying to solve this problem for a couple of days now and have tried SO many different things, please forgive me if I've left some of those out here. Any assistance would be greatly appreciated.

Unexplicable InvalidURIError after controller testing Posted: 30 Dec 2016 07:03 AM PST I was testing my Rails 5.0 application with the following code: test "destroy should require logged-in user" do assert_no_difference 'AtpSelection.count' do delete :destroy, params: { id: atp_selections(:selection_1) } end assert_redirected_to login_url end but the test kept failing: ERROR["test_destroy_should_require_logged-in_user", AtpSelectionsControllerTest, 1.9559332270000596] test_destroy_should_require_logged-in_user#AtpSelectionsControllerTest (1.96s) URI::InvalidURIError: URI::InvalidURIError: bad URI(is not URI?): http://www.example.com:80destroy So, in order for the test to pass, I had to change my code using instead the following code: test "destroy should require logged-in user" do assert_no_difference 'AtpSelection.count' do delete atp_selection_path(atp_selections(:selection_1)) end assert_redirected_to login_url end I have no idea why I could not make the test pass calling delete directly on the controller action :destroy. I made this same choice in other tests I created before for other controllers and they succeed without raising errors.

What i wrong with my html.erb file? Posted: 30 Dec 2016 07:08 AM PST from the code below, I get the following error: /home/ubuntu/workspace/portfolio/app/views/projects/_project_form.html.erb:36: syntax error, unexpected keyword_ensure, expecting end-of-input because it is a syntax error, I am guessing I wont need to provide other details but if you guys need me to post more feel free to ask. <%= form_for @project do |f| %> <% if @project.errors.any? %> <div id="error_explanation"> <h2> <%= "#{pluralize(@project.errors.count, "error")} prohibited this project from being saved:" %> </h2> <ul> <% @project.errors.full_messages.each do |msg| %> <li> <%= msg %> </li> <% end %> </ul> </div> <% end %> <div class="field"> <%= f.label :client %> <p> <%= @project.client.name %> </p> <%= f.hidden_field:note_id, value: @project.client.id %> <% end %> </div> <div class="field"> <%= f.label :project_description %> <%= f.text_area :project_description %> </div> <div class="field"> <%= f.label :project_timescale %> <%= f.text_field :project_timescale %> </div> <div class="actions"> <%= f.submit 'Save' %> </div> <% end %>

Database configuration errors while deploying Rails app to Heroku Posted: 30 Dec 2016 06:55 AM PST I'm using Rails 4.2.3 I received the classic "sqlite not supported" error initially, and then removed all references to sqlite. Now I'm getting: remote: Cleaning up the bundler cache. remote: -----> Detecting rake tasks remote: -----> Preparing app for Rails asset pipeline remote: Running: rake assets:precompile remote: rake aborted! remote: URI::InvalidURIError: bad URI(is not URI?): ://user:pass@127.0.0.1/dbname My database.yml looks like this: production: url: <%= ENV['CLEARDB_DATABASE_URL'] %> I've also tried: production: url: <%= ENV['DATABASE_URL'] %> production: encoding: utf8 pool: 15

How can i call model method in Rails 5 with ajax? Posted: 30 Dec 2016 06:53 AM PST I've a Task model in Rails with this method def notify(user) Task.where(assignee: user).where(notified: false).count end that returns the number of particular tasks. I need to call it via Ajax, how can i do it? I know that i could use it in a controller method and call Ajax to controller (i know how to do this) but then the controller method would be attainable via url.

When is touch_record (belongs_to.rb) called? Posted: 30 Dec 2016 07:38 AM PST In this method from belongs_to.rb, def self.touch_record(o, foreign_key, name, touch) I am trying to get the 'o' class. I try : bundle show activerecord then open 'thepathgivenbymyfirstcommand' and put a 'binding.pry' in the method Finally, I moved into a rails project (with belongs_to association already created) and try to update/destroy as they said here :":touch If true, the associated object will be touched (the updated_at/on attributes set to now) when this record is either saved or destroyed. If you specify a symbol, that attribute will be updated with the current time in addition to the updated_at/on attribute." but nothing happened, I never stop at the "binding.pry" to get the 'o' variable class. Do you have any advice ?

Sass::Engine.new Rails | Compiled css file has code from the scss.erb template file causing the css file to have errors Posted: 30 Dec 2016 06:31 AM PST I have made use of the Sass engine in rails to produce a custom css file for each element a user can add to the site. This is my generate css code def generate_css Sass::Engine.new(asset_source, { syntax: :scss, cache: false, read_cache: false, style: :compressed }).render end The template file it uses is just a list of variables and a sass if statement to check which mix-in to use. This when compiled seems to keep around 22 lines of code from the template file. This isn't a major problem as the css file still renders in the browser fine but it is annoying knowing I have incorrect/ erroneous files. Any ideas on how to trim/remove reformat the final compiled css?

Using Cassandra in Rails App Posted: 30 Dec 2016 05:42 AM PST I have a couple of questions about working with Ruby on Rails and Cassandra. I have a PostgreSQL database and a Cassandra database separate from my Rails application. I would like to access Cassandra to make some queries through my Rails application. What is the recommended way of Cassandra integration into a Rails app ? Is there any reference implementation? Regards,

Rails navbar conditional and getting No route matches in root_path Posted: 30 Dec 2016 05:46 AM PST Hello I want to show the search form inside the navbar only in the index page of products and the show page of the product. The thing is that it is showing on both the index page and the show page but when I click home to go to the root_path I get the following error: No route matches {:action=>"show", :controller=>"products"} missing required keys: [:id] How can I avoid that? This is my code in the application.html.erb: <% if current_page?(products_path) || (product_path) %> <div class="col-sm-3 col-md-3 pull-right"> <form class="navbar-form" role="search"> <div class="input-group"> <input type="text" class="form-control" placeholder="Search" name="search_term" id="search_term"> <div class="input-group-btn"> <button class="btn btn-default" type="submit"><i class="glyphicon glyphicon-search"></i></button> </div> </div> </form> </div> <% end %>

Rails: how to check CSS or JS code code from a string? Posted: 30 Dec 2016 05:34 AM PST In a code string I have stored a piece of code, can be CSS, SASS, SCSS, JavaScript or CoffeeScript. I need to check if the syntax is correct. Currently I found a ugly hack which works. Do you know a better solution? def check_js if language == 'coffee' CoffeeScript.compile code else Uglifier.compile code end rescue ExecJS::RuntimeError => e errors.add :code, e.message end def check_css if language == 'css' Sass::CSS.new(code).render else Sass.compile code, syntax: language.to_sym end rescue Sass::SyntaxError => e errors.add :code, e.message end

FriendlyID for child Posted: 30 Dec 2016 05:32 AM PST I have a Project model that belongs to a User. A User has_many Projects. I have setup FriendlyID according to the gem instructions for User model, however it is not working in this scenario. <%= link_to gravatar_for(project.user, size: 50), project.user %> The above creates a link with the numerical ID of the user (project.user) instead of a friendly URL (i.e. http://localhost:3000/users/102 instead of what I want, http://localhost:3000/users/*random-gen-string*). User.rb file: class User < ApplicationRecord extend FriendlyId friendly_id :generated_slug, use: :slugged def generated_slug require 'securerandom' @random_slug ||= persisted? ? friendly_id : SecureRandom.hex(15) end I think the problem is that project.user is set in the projects_controller.rb to the user ID (via current_user.projects.build...). If I could somehow access the Friendly ID for User in the projects_controller.rb I may be able to save it in the database and access it like project.user_friendly_id. Not sure.. Relevant code in projects_controller: def create @project = current_user.projects.build(project_params) # code end What is the best way to go about making the above link link to the Friendly ID and not the user (i.e. http://localhost:3000/users/*random-gen-string* is what I want instead of http://localhost:3000/users/102)?

Posted: 30 Dec 2016 04:44 AM PST What needs to be changed in the below queries?. i want all those employees whose date_of_leaving is null or the date_of_leaving is in between the past 60 days or the date_of_leaving is greater than or equal to the Date.today or current date. employees = @company.employees.where('date_of_leaving BETWEEN ?

Rails, how to use a block in where statement Posted: 30 Dec 2016 06:33 AM PST Taken from this stackoverflow-question, one can use a block for a query, like this: Consumer.find do |c| c.id == 3 end I want to do the same with a "where" query, for example: mainCustomers = Customer.where do |c| c.id == c.main end When I do this, I get something like this: => #<ActiveRecord::QueryMethods::WhereChain:0x0055a057444560 @scope=#<ActiveRecord::Relation I can't use ActiveRecord methods, for example: irb(main):013:0> mainCustomers.last NoMethodError: undefined method `last' for #<ActiveRecord::QueryMethods::WhereChain:0x0055a057444560> or irb(main):014:0> mainCustomers.count NoMethodError: undefined method `count' for #<ActiveRecord::QueryMethods::WhereChain:0x0055a057444560> What is the correct way for using blocks in a where statement?

Adding a scope to ruby gem validation of uniqueness Posted: 30 Dec 2016 04:32 AM PST acts-as-taggable-on gem has a built-in uniqueness validation: validates_uniqueness_of :name, if: :validates_name_uniqueness? def validates_name_uniqueness? true end How do I add a scope to this validation?

Two levels of nested attributes and strong parameters Posted: 30 Dec 2016 03:21 AM PST I've ported a Rails app from Rails 3 to Rails 4 and most things work now, except for a problem with two levels of nested attributes: I have ProductGroups, Variants and Prices. Each ProductGroup has one or more variants. One of them is the master variant. Each variant has many prices (one for each region). I have a controller that updates ProductGroups. When the ProductGroup is updated, the master variant is updated at the same time. And prices in the master variant are also updated. Here's a test that describes what's expected to happend: test "should update master variant" do login_as accounts(:johnny_admin) p = ProductGroup.find product_groups(:toothbrush).id assert_equal "10123", p.artno assert_equal "10123", p.master_variant.artno puts(p.master_variant.prices.to_a.to_s) post :update, id: product_groups(:toothbrush), p: 'setup', product_group: { master_variant_attributes: { artno: "20222", supplier_artno: "1010", prices_attributes: { "0": { price: "55", id: prices(:toothbrush_price_se).id } } } } assert_response :redirect assert_redirected_to edit_admin_product_group_path(p, :p => 'setup') p = ProductGroup.find product_groups(:toothbrush).id assert_equal "20222", p.artno assert_equal "20222", p.master_variant.artno assert_equal "1010", p.master_variant.supplier_artno price = Prices.find prices(:toothbrush_price_se).id assert_equal 55, price.price end But it fails with this error: # Running: .......[#<Price id: 510149407, variant_id: 630858089, region_id: 102782309, price: #<BigDecimal:55d2732f50a8,'0.95E2',9(18)>, created_at: "2016-12-30 11:14:28", updated_at: "2016-12-30 11:14:28">, #<Price id: 524805804, variant_id: 630858089, region_id: 960235695, price: #<BigDecimal:55d27339c510,'0.1E2',9(18)>, created_at: "2016-12-30 11:14:28", updated_at: "2016-12-30 11:14:28">] E Finished in 1.279989s, 6.2501 runs/s, 20.3127 assertions/s. 1) Error: Admin::ProductGroupsControllerTest#test_should_update_master_variant: ActiveRecord::RecordNotFound: Couldn't find Price with ID=510149407 for Variant with ID= app/controllers/admin/product_groups_controller.rb:150:in `update' test/functional/admin/product_groups_controller_test.rb:103:in `block in <class:ProductGroupsControllerTest>' As you can see in the debug output, there is a price with ID 510149407 for that variant.

Any hints would be much appreciated!

Error: Postgres database import in docker container Posted: 30 Dec 2016 05:49 AM PST I'm running a ruby on rails application in docker container. I want to create and then restore the database dump in postgres container. But I'm Below is what I've done so far: 1) Added bash script in /docker-entrypoint-initdb.d folder. Script is just to create database: psql -U docker -d postgres -c 'create database dbname;' RESULT: Database created but rails server exited with code 0. Error: web_1 exited with code 0 2) Added script to be executed before docker-compose up. # Run docker db container echo "Running db container" docker-compose run -d db # Sleep for 10 sec so that container have time to run echo "Sleep for 10 sec" sleep 10 echo 'Copying db_dump.gz to db container' docker cp db_dump/db_dump.gz $(docker-compose ps -q db):/ # Create database `dbname` echo 'Creating database `dbname`' docker exec -i $(docker-compose ps -q db) psql -U docker -d postgres -c 'create database dbname;' echo 'importing database `dbname`' docker exec -i $(docker-compose ps -q db) bash -c "gunzip -c /db_dump.gz | psql -U postgres dbname" RESULT: Database created and restored data.

But getting an error: web_1 exited with code 0. I'm confused why I'm getting this error (in first and third approach), seems to be something is messed up in docker-compose file.

How to password protect Munin directory? Posted: 30 Dec 2016 03:19 AM PST I followed Munin, apache and how to password protect munin and have added .htaccess file in /var/www/munin with this code AuthType Basic AuthName "My Protected Area" AuthUserFile /var/www/munin/.htpasswd Require valid-user I have also generated .htpasswd file with apache utils has it has the username and md5 password. Now after reloading and restarting apache, I can still see example.com/munin content.

Can you suggest me what I am missing out or if there is any other way using which I can password protect munin content ?

How obtain connect with OAuth 2 using Postman? Posted: 30 Dec 2016 03:22 AM PST My API uses the devise_token_auth (omniauth) gem for authentication in the Rails 5 backend. The frontend are using ng-token-auth (Angular 1.x). I have all the API requests in Postman. I did the security implementation and I need authenticate Postman with every request. Devise_token_auth uses authentication with OAuth 2 and I am having difficulty to implementing this authentication. For this type of authentication, using Postman, what is the process needed to obtain the connection?

Create Wistia model in Ruby on Rails Posted: 30 Dec 2016 03:40 AM PST I am building currently an web app where the admin will be able to post a title with a description and a link / embedded form of Wistia Video Player. Currently my setup is: Welcome Page Dashboard Page with Dashboard Controller (here only the admin will be able to post, edit things, all other users can only watch/comment) How do i create a model for this? Normally i would create a model like this: rails g model Video title:string description:text But how do i implement the Wistia Video Player, so that everytime the Admin creates a new post, he will be able to link/embedded a new video?

Rails: Accessing image files after being uploaded Posted: 30 Dec 2016 02:56 AM PST I am writing a Ruby on Rails 5 app. I just learned how to upload an image without using paperclip,carrierwave, or refile. I have used refile in the past but for this app, I wanted to learn how to do it with out those third party gems. And it was not that difficult to do. I have successfully uploaded a file. My problem is accessing the image afterwards! I thought this would be rather simple. But NO! I have image files being uploaded to "/public/images/page/image.jpg" I have added "/public/images/page" to the assets path in app/initializers/assets.rb I have tried straight img tag like this: <img class="pic left" src="/public/images/page/mars01.jpg" alt="Mars01" /> I get a "(No route matches [GET] "/public/images/page/mars01.jpg")" error. I have tried: <%= image_tag "/public/images/page/#{@page.image}", class: 'pic left' %> basically the same as tag, get same results. Also tried: <img class="pic left" src='<%= image_path "#{@page.image}" %>' /> still get routing error, but only looking in "/images" directory. I am still in development mode, so I thought that image_path would be the correct path. What is the correct way of accessing an image, that was just uploaded to a directory outside of the asset pipeline? That will work in development or production env? I really thought this would be straight forward.

Rails 4 after_commit nested conditions issue Posted: 30 Dec 2016 04:34 AM PST I would like to trigger the same function for after_commit on both update and create BUT I would like to apply a particular condition only for update. For now, my only solution was to duplicate the function and make two different after_commit like this: after_commit :my_method_on_update, on: :update, if: ->(foo) { foo.previous_changes.key?(:bar) } after_commit :my_method_on_destroy, on: :destroy def my_method_on_update # stuff end def my_method_on_destroy # same stuff here end Of course it works but it doesn't make the code DRY at all. I'm sure there is a better solution but I haven't found any relevant examples on the official rails doc What I'd like is something like this: after_commit :my_method, on: :update, if: ->(foo) { foo.previous_changes.key?(:bar) }, on: destroy def my_method # stuff end But there is an error with twice the declaration of on.

Active Admin Installation Error Posted: 30 Dec 2016 04:41 AM PST I created a sample application in RubyonRails and tried to use Active Admin gem. Added the below lines to Gem file: gem 'activeadmin' gem 'sass-rails' gem "meta_search", '>= 1.1.0.pre' Then ran the following command rails generate active_admin:install but got the below error: Running via Spring preloader in process 1726 Expected string default value for '--jbuilder'; got true (boolean) Expected string default value for '--helper'; got true (boolean) Expected string default value for '--assets'; got true (boolean) Could not find generator 'active_admin:install'. Maybe you meant 'active_record:model', 'active_record:migration' or 'integration_test' Run `rails generate --help` for more options.

Posted: 30 Dec 2016 02:25 AM PST I have been following this simple tutorial for sending mail using ActionMailer. http://guides.rubyonrails.org/action_mailer_basics.html The configuration i am using in development.rb file is as follows: config.action_mailer.delivery_method = :smtp config.action_mailer.smtp_settings = { :address => 'smtp.mailgun.org', :domain => 'sandbox1b1a6a9b09cb4df4b1e7489ad0747f6d.mailgun.org', :port => 587, :user_name => 'postmaster@sandbox1b1a6a9b09cb4df4b1e7489ad0747f6d.mailgun.org', :password => 'validpassword', :authentication => 'plain' } config.action_mailer.raise_delivery_errors = true config.action_mailer.perform_deliveries = true I have also tested with gmail smtp but with no success. The above configuration is for mailgun smtp. I send email through the terminal and the following message is printed in console. But the email is never received by the recipient. I am doubtful whether i have missed an important configuration for cloud 9 that is not letting me send emails. I appreciate any help! Thanks!
