Top 3 hosted CI (continuous integration) for Rails apps

Here's my summary of top 3 hosted solutions for Rails continuous integration are:

- https://semaphoreapp.com/features
- https://www.circleci.com/
- Tddium

Tddium looks very configurable and gives power to the commandline, eg. run builds from local console on branches. $15/mth for 10 worker hours.

CircleCI had good reviews and sounded like it runs builds really fast. Like Tddium, it's configurable via a yaml file. No official price plans on website but responded via twitter that theirs plans starts from $19.

Semaphore selling point's their "simple stupid" approach to CI. Oauth via Github, add collaborators and boom. Runs are every git push and at a price of $14/mth, it seemed the cheapest of 'em lot.

My vote is for Semaphore since it's the cheapest and simplest to use for a small project.

Update all associations of a Rails model

  @msg_thread.messages.update_all(status: 'read')

Ember.js gotcha - require handlebar.js

Require handlebar.js BEFORE ember.js

# in rails
//= require handlebars
//= require ember

Scope javascript variable in coffeescript so it's available in browser

App = Foo.bar

window.App = App

Rails scaffold only the controller resource

rails g scaffold_controller users

Customizing devise views & controllers

I find myself repeating and googling this far too many times...

# Generate the devise views
rails g devise:views

# Add customize views resource to route
devise_for :users, controllers: { registrations: "users/registrations" }

# Move views to new resource folder
git mv app/views/devise/registrations/ app/views/users/

# Add new custom devise controller
class Users::RegistrationsController < Devise::SessionsController

  def new
    @user = User.new
  end

  def create
    ...
  end

end

Cannot customize default devise views

DO NOT use Devise to generate scoped views.

rails generate devise:views users

Just use

rails generate devise:views
