The way of writing Rabl templates is very clearly described in their repo. -Add Rabl to your Gemfile before requiring gon - because gon checks Rabl constant - - `Gemfile` - - ``` ruby - gem 'rabl' - ... - gem 'gon' - ``` - Profit of using Rabl with gon: 1. You can clean your controllers now! 2. Work with database objects and collections clearly and easyly 3. All power of Rabl 4. You can still be lazy and don't use common way to transfer data in js 5. And so on -For using gon with Rabl you need to create new Rabl template and map gon -to it. -For example you have model Post with attributes :title and :body. -You want to get all your posts in your js as an Array. -That's what you need to do: +[Instruction](https://github.com/gazay/gon/wiki/Usage-with-rabl) for +usage gon with Rabl. - 1. Create Rabl template. You can choose spepicific directory but better - use default directory for action. - - `app/views/posts/index.json.rabl` - - ``` rabl - collection @posts => 'posts' - attributes :id, :title, :body - ``` - - 2. If you create template in default directory for action, you just write in this action: - - `app/controllers/posts_controller.rb#index` - - ``` ruby - def index - # some controller logic - @posts = Post.all # Rabl works with instance variables of controller - - gon.rabl - # some controller logic - end - ``` - - But if you choose some specific category - you need to map this template to gon. - - `app/controllers/posts_controller.rb#index` - - ``` ruby - def index - # some controller logic - @posts = Post.all # Rabl works with instance variables of controller - - gon.rabl :template => 'app/goners/posts/index.rabl' - # some controller logic - end - ``` - - Thats it! Now you will get in your js gon.posts variable which is Array of - post objects with attributes :id, :title and :body. - -In javascript file for view of this action write call to your variable: - -``` js -alert(gon.posts) -alert(gon.posts[0]) -alert(gon.posts[0].post.body) -``` - -P.s. If you didn't put include_gon tag in your html head area - it -wouldn't work. You can read about this in common usage above. - -### Some tips of usage Rabl with gon: - -If you don't use alias in Rabl template: - -``` rabl -collection @posts -.... -``` - -instead of using that: - -``` rabl -collection @posts => 'alias' -.... -``` - -Rabl will return you an array and gon by default will put it to variable -gon.rabl - -Two ways how you can change it - using aliases or you can add alias to -gon mapping method: - -``` ruby -# your controller stuff here - -gon.rabl :as => 'alias' -``` - ## Usage with Jbuilder Use gon with [Jbuilder](https://github.com/rails/jbuilder) as with [Rabl](https://guthub.com/nesquena/rabl): - 0.

Create Jbuilder template. - - `app/views/posts/index.json.jbuilder` - - ``` jbuilder - json.posts @posts, :id, :title, :body - ``` - - 2. In your controller you should just call 'gon.jbuilder' - if your template in - default directory for action.
