A small example using rails-backbone gem
Created a new rails application called blog.
rails new blog
Edit your Gemfile and add
gem 'rails-backbone'
Install the gem and generate scaffolding.
bundle install
rails g backbone:install
rails g scaffold Post title:string content:string
rake db:migrate
rails g backbone:scaffold Post title:string content:string
You now have installed the backbone-rails gem, setup a default directory structure for your frontend backbone code. Then you generated the usual rails server side crud scaffolding and finally generated backbone.js code to provide a simple single page crud app. You have one last step:
Edit your posts index view app/views/posts/index.html.erb with the following contents:
<div id="posts"></div>
<script type="text/javascript">
$(function() {
// Blog is the app name
window.router = new Blog.Routers.PostsRouter({posts: <%= @posts.to_json.html_safe -%>});
Backbone.history.start();
});
</script>
If you prefer haml, this is equivalent to inserting the following code into app/views/posts/index.html.haml:
#posts
:javascript
$(function() {
// Blog is the app name
window.router = new Blog.Routers.PostsRouter({posts: #{@posts.to_json.html_safe}});
Backbone.history.start();
});
Now start your server rails s and browse to localhost:3000/posts
You should now have a fully functioning single page crud app for Post models.
####With Rails 4:#### If you are using the default Rails 4 scaffold generators, you will need to adjust the default JSON show view (IE, 'show.json') to render the 'id' attribute.
default rails generated show.json.jbuilder
json.extract! @post, :title, :content, :created_at, :updated_at
Change it to add id attribute as well
json.extract! @post, :id, :title, :content, :created_at, :updated_at
Without adjusting the JSON show view, you will be redirected to a "undefined" url after creating an object.
