| How do I use a before_action type callback in ActiveRecord Models Posted: 30 Sep 2016 07:53 AM PDT I have a database model that doesn't actually have any data since all my User informatio is stored on a third party authentication service. I want to be able to use the Model like a regular one, so upon load, I fetch all the information from the API and store it in an instance variable. How do I setup a before_action like callback for my model? Is there a Ruby way to do this? class Auth0User < ApplicationRecord before_action set_instance_variables validates :auth0_id, presence: true, uniqueness: true def info(key = nil) key.nil? ? @user : @user[key.to_s] end private def set_instance_variables @user ||= auth0_api.user auth0_id end def auth0_api Auth0Client.new( client_id: Rails.application.secrets.auth0_client_id, token: Rails.application.secrets.auth0_management_jwt, domain: Rails.application.secrets.auth0_domain, api_version: 2 ) end end

| Rails app instances & memory usage Posted: 30 Sep 2016 07:35 AM PDT Is the memory usage for number of Rails app instances linear? I have a rails app on heroku that normally runs on a a couple dynos with 2 app instances per. We've been offered a free month of a Performance-L dyno so I've been playing around with the web concurrency a little bit. I noticed that initially moving from 2 to 4 seemed to double the memory usage. But as I continued to increase the app instances, the increase in memory slowed. Currently I have 40 app instances running on this 14GB machine and am only using about 6GB. Is it simply a matter of not enough traffic for them all to be initialized? What else is at play here and what are my limitations to how many instances I can run on this Performance-L Dyno? |
| Devise Ajax session for confirmable user Posted: 30 Sep 2016 07:34 AM PDT I have an ajax form for users sign up. I have problem when i try to login user which isn't confirmed. It never reach's create action from session controller if i enter valid username and password, if i write wrong password for user, i get inside create action and return good response from invalid_login_attempt method. Sessions controller: class SessionsController < Devise::SessionsController def create debugger resource = Bbp::User.find_for_database_authentication(email: params[:user][:email]) return invalid_login_attempt unless resource return invalid_login_attempt unless resource.valid_password?(params[:user][:password]) return confirmation_needed if resource.confirmed_at.nil? if resource.valid_password?(params[:user][:password]) sign_in :user, resource return render nothing: true end invalid_login_attempt end protected def invalid_login_attempt render json: "Wrong username or password", status: 401 end def confirmation_needed render json: "You need to confirm your email before you can continue", status: 401 end end
And my form is: <h2>Sign in</h2> <div class="message-success-field user-sign-in-row"></div> <%= form_for(resource, as: resource_name, url: '/admin.json',html: {id: 'new_user_session'}, remote: true ) do |f| %> <div class="form-group"> <%= f.email_field :email, class: "form-control", placeholder: "Email", autofocus: true %> </div><!-- form-group --> <div class="form-group"> <%= f.password_field :password, class: "form-control", placeholder: "Password #{'(' + @minimum_password_length.to_s + ' characters minimum)' if @minimum_password_length}", autocomplete: "off" %> </div><!-- form-group --> <% if devise_mapping.recoverable? %> <small><%= link_to "Forgot your password?", new_password_path(resource_name) %></small><br /> <% end %> <% if devise_mapping.rememberable? %> <div class="field"> <%= f.check_box :remember_me %> <%= f.label :remember_me %> </div> <% end %> <%= f.button "Sign in", class: "form-control btn btn-success" %> <p>Or connect via Facebook</p> <%= link_to "Sign in with facebook", "/auth/facebook", class: "form-control btn btn-primary" %> <% end %> <script> $(document).ready(function() { $('#new_user_session') .bind('ajax:success', function(response, evt, data, status, xhr) { $('div.user-sign-in-row').empty() $('div.user-sign-in-row').append("You are successfully logged in") }) .bind("ajax:error", function(evt, xhr, status, error) { $('div.user-sign-in-row').empty() $('div.user-sign-in-row').append(xhr.responseText) }); }); </script>
I think this happens because somewhere before create, devise checks if user is comfirmable, but i can't find where is that. I also set that sessions controller respond to html and json. What can be issue? |
| Better? design software to build a modules/plans architecture Posted: 30 Sep 2016 07:25 AM PDT It is very common today found systems with sign plans, like Free Plan, Hobby Plan, etc. It's seems easy to build, just add some extra validation in the plan that you did sign. But, how to build a maintainable software for each plan? Write IFs and ELSEs on models, controllers & views? Using RoR, I think the better way is using modules. Like, you are the Free Plan, so add the Plans::Free in controllers and models to do specifics validations. I cannot think a better idea to excludes the IFs ELSEs. Is there a better design? Of course is there, but which? |

Ruby on Rails
Cron: Whenever
I set up environment variables for DB name, DB password and DB host. I am sure those variables show up with env command. But I cannot use them in rails codes or yaml files like <%= ENV["DB_NAME"] %>. They are nil. When I put DB name in database.yml directly, it works. There are logs saying "No database selected" something like that.

| double polymorphic association with same tables? any idea on how to preload them? Posted: 30 Sep 2016 06:33 AM PDT I have CallSession table. it has polymorphic associations: class CallSession < ActiveRecord::Base belongs_to :callable, polymorphic: true belongs_to :calleeable, polymorphic: true end
CallSession has callable_type,callable_id,calleeable_type and calleeable_id. the members of callable assoc are Doctor table and Consumer table, and calleeable assoc has Doctor and Consumer table. (yeah the same tables) now, I need to query CallSession where its callable Email is different from its calleeable Email (Both Doctor and Consumer has Email,both can be callable or calleeable). One email can be used for both Doctor and Consumer object. any idea on how to query it in one Scope with preloads to avoid N+1? thanks in advance! at worst I will store the callable.email and calleeable.email in new columns. |

| Rails on Elastic Beanstalk, Can't do a load balancer health check Posted: 30 Sep 2016 05:55 AM PDT I am running a rails app on elastic beanstalk, my problem is that I cannot use the load balancer health check, as it checks via http, not https. I have config.force_ssl set to true, and don't really want to change it, since it means I have 100% ssl coverage, HSTS, and secure cookies. I have setup a controller to check at /health and can access this via curl. There seems to be a contradiction between what is shown in elastic beanstalk (EC2 Instance Health Check), where I can only change the path and some timings, and the health check in the load balancer in EC2, where I can change the ping protocol, port and path to what I want, but this seems to have no effect other than causing a 503 error. Ping Protocol: https Ping Port: 443 Ping Path: /health
The load balancer has ports 80 and 443 open but redirects from 80 to 443 due to force_ssl. Does anyone know of the correct settings to get around this, as I won't be able to scale the application without it? Thank you Eamon |

| How to create an association between two models with form choice field using Active Admin, Paperclip in Rails 5.0.1 Posted: 30 Sep 2016 05:52 AM PDT Scenario I am building a similar App like AirBnB but the difference is that only the Admin can add new Apartments, Rooms, Houses etc. Therefore I created an Admin Panel with the activeadmin gem. I am now adding the image upload system into activeadmin so I am using the paperclip gem. I have two models "room" and "photo". The photo model has an "image" column. The room model has an "listing_name" column. room.rb (app/models) class Room < ApplicationRecord has_many :photos end
photo.rb (app/models) class Photo < ApplicationRecord belongs_to :room has_attached_file :image, styles: { medium: "300x300>", thumb: "100x100>" } validates_attachment_content_type :image, content_type: /\Aimage\/.*\z/ end
If I am not putting a custom form inside "photo.rb (app/admin)" I can associate the image to a room by default. But I can't upload a picture! This looks like this: 
So I changed the "photo.rb (app/admin)" file into this: photo.rb (app/admin) ActiveAdmin.register Photo do permit_params :image form :html => {:multipart => true} do |f| f.inputs "Project Details" do f.input :image, :required => false, :as => :file end f.actions end show do |ad| attributes_table do row :image do image_tag(ad.image.url(:thumb)) end end end end
With this form I can upload a picture into the image column but I can't associate it to a room and the edit view does not give me a preview of a picture as the show view does: 
Questions: How can I have a preview of the image in the admin edit view? How can build a form to associate an image to a room by choosing the listing_name of the room? Something like this:

| While integration testing, ActionController::ParameterMissing appears, despite logs to the contrary Posted: 30 Sep 2016 05:26 AM PDT I have installed Rails using the instructions from https://gorails.com/setup/ubuntu/16.04 on an Ubuntu 16.04 amd64 server. I used 'rbenv' rather than any of the other options. I created a new application named 'testapp'. I then executed: $ rails generate scaffold Test name:string age:integer
Then, I executed: $ bin/rails generate integration_test tests_post
I modified test/integration/tests_post_test.rb to read as follows: require 'test_helper' class TestsPostTest < ActionDispatch::IntegrationTest test "can create an item" do get "/tests/new" assert_response :success post "/tests", params: { test: { name: 'Micky Mouse', age: 120 } } assert_response :redirect follow_redirect! assert_response :success end end
And then I executed: rake test
This gives me the following error: Run options: --seed 24994 # Running: .......E Finished in 0.247049s, 32.3822 runs/s, 56.6689 assertions/s. 1) Error: TestsPostTest#test_can_create_an_item: ActionController::ParameterMissing: param is missing or the value is empty: test app/controllers/tests_controller.rb:72:in `test_params' app/controllers/tests_controller.rb:27:in `create' test/integration/tests_post_test.rb:8:in `block in <class:TestsPostTest>' 8 runs, 14 assertions, 0 failures, 1 errors, 0 skips
Yet, the relevant logging shows the following: -------------------------------------- TestsPostTest: test_can_create_an_item -------------------------------------- Started GET "/tests/new" for 127.0.0.1 at 2016-09-30 07:50:18 -0400 Processing by TestsController#new as HTML Rendered tests/_form.html.erb (13.6ms) Rendered tests/new.html.erb within layouts/application (16.4ms) Completed 200 OK in 170ms (Views: 161.1ms | ActiveRecord: 0.0ms) Started POST "/tests" for 127.0.0.1 at 2016-09-30 07:50:19 -0400 Processing by TestsController#create as HTML Parameters: {"params"=>{"test"=>{"name"=>"Mickey Mouse", "age"=>"120"}}} Completed 400 Bad Request in 0ms (ActiveRecord: 0.0ms)
In development and in production, this gives no errors, only in test. I keep looking over examples I've seen online in other projects, but I don't see that I'm doing anything particularly out of the ordinary here.

| More efficient to update or rebuild Rails 2.3.X app? Posted: 30 Sep 2016 04:32 AM PDT I have a Rails 2.3.X app. I plan to hire a developer to either update the site to current Rails standards or rebuild the site. In general, is there a way to evaluate whether it's more cost-effective to update versus rebuild? My preference is to update. |
| Safe way to allow Rails code review? Posted: 30 Sep 2016 04:29 AM PDT I have someone interested in purchasing my Rails app (2.3.18). It requires updating (obviously), and now it's a question of the cost of updating versus rebuilding from scratch. If the buyer wants to have third-party developer review the code to determine this effort and estimate costs, is there a way to allow this developer access without losing control or granting unsafe access? |
| How to filter the range using Axlsx with filters on some columns Posted: 30 Sep 2016 04:07 AM PDT I am generating a spreadsheet using Axlsx gem. My data table has more than 10 columns but I have to add filters to first 5 columns only. sheet.auto_filter = "A5:E20"
The problem is that these filters works only on 5 columns not on the whole table which has 10 columns. So for example when I sort the table by the first column only cells in these first 5 columns are sorted and the other cells are not touched. Is there a way to have filters on some columns but makes filtering working on the whole table? |

| How to Embed a PowerBI Tile in a Rails app? (and apply filter to it) Posted: 30 Sep 2016 03:35 AM PDT I'm struggling with this since a week... I have tried so many things, read so many documentations (walkthrougsh), I can't find any solutions and I have lost the clarity. I really need your help. I have created a simple Rails app. I have a Power BI account and a Azure account. I'm using an example set of data on PowerBI (Retail Analysis Sample). I want my users to signin on my app (through devise), then access to some pages and see embedded PowerBI Tiles (or report, or dashboard maybe). Then I want them to be able to filter the results. A client-side example is https://microsoft.github.io/PowerBI-JavaScript/demo/filters.html. I want to be able to do the same. I'm lost with all the client id, secret, ressource uri, ressource url, ... What solution/walkthrough must I use?
Thank you so much for your time Fro |

| Supporting two incompatible gem versions for a dependency Posted: 30 Sep 2016 04:03 AM PDT I have a gem that I use which currently depends on the google-api-client v 0.8x, I'd like to update the gem to support google-api-client v 0.9x. The Auth between those two is completely different and incompatible. Is there a way to know which version of the gem dependency is intalled and act accordingly? So I can add the support for those people who for whatever reason have upgraded the API client whilst continuing to allow people still on the older version to use it. |
