This project has fallen out of date and I don't intend to maintain it. I strongly recomment people move to ember-cli-based architectures as this is the future of ember. I have a couple of ember-cli based apps with companion Rails/Devise apps you can look at crambear/crambear-api and emblog/emblog-server.
Ember Rails Devise Demo
This app is working example of using Ember with Rails and Devise.
The running app can be viewed at: http://emrailsdevise.herokuapp.com/
For a more full-featured Ember example app using Ember, Rails and Devise, see Crambear, an Ember flashcards app.
- User Login and Registration using Devise
- Illustrates basic usages of Ember components like routes, controllers, and templates.
Currently runs on Ember.js 1.0
To run the app:
(clone or fork the project) $ bundle install $ bundle exec rake db:create $ bundle exec rake db:migrate $ bundle exec rake db:seed #will create a test user, or just register a new one from the app $ export ERD_SECRET_KEY_BASE='generate-a-secret-key' #used in initializers/config/secret_token.rb $ rails server
Basic Architecture of an Ember App
In traditional Rails apps, pretty much every user click results in an HTTP request. The server processes the request, and generate an HTML page, which it returns to the client. This happens even for tasks the client has the data to handle, such as sorting a list on the page.
In the Ember/Rails world, Ember handles client interactions and page display. Rails may serve the initial page, as done here (also can be done by an HTTP server like nginx). Then it waits for AJAX requests and responds with JSON, often using a gem such as Active Model Serializers.
Under this architecture, the Rails components which pertain directly with the client are:
- a bare-bones layout (views/layouts/application.html) which includes the Ember client and css
- a blank root page (here view/home/index)
- a root controller (here HomeController)
- routes defined in routes.rb
- serializers, here using the active_model_serializer gem for packaging (in the app/serializers directory)
Devise with AJAX
When using Devise with AJAX you must add:
respond_to :html, :json
to the appropriate Rails controller(s). In this app, its been added to ApplicationController. More here.
There are a couple of capybara-webkit tests up. The first tests a registration-logout-login cycle. Was going to separate these out, but the standalone login test doesn't work for some reason (even though works in development). Appreciate if anyone can figure this out.
The tests here are for reference to show how to set up Konacha and far from comprehensive.
Setup is easy:
- Add the gem to your gemfile (and run bundle install)
- Write some tests
- Run the task: bundle exec rake konacha:serve. This will startup up a server running, by default" on port 3500.
- Go to localhost:3500 to see test results
See the Konacha github page for detailed info.
Most immediately, validations and tests are sparse. Plan to add features as time goes by.
