Setting up RABL on Sinatra is easy. In fact it's as easy as 1..2..3
Install the gem
$ gem install sinatra
Set up your sinatra app to support RABL:
# app.rb require 'rubygems' require 'sinatra' require 'rabl' require 'active_support/core_ext' require 'active_support/inflector' require 'builder' # Register RABL Rabl.register! # Render RABL get "/" do @foo = # ... rabl :foo, :format => "json" # or render :rabl, :foo, :format => "json" # or Rabl::Renderer.json(@foo, 'path/foo/index', view_path: 'app/views') end
Note that if your view templates are stored anywhere other than the
views directory, you must tell Sinatra and/or RABL. If you are rendering your templates with
Rabl::Renderer.json(...), you need to set the RABL
view_paths config variable. If you are using either
render :rabl... or
rabl ..., you need to change the Sinatra
views setting, or pass in a
views local variable. Remember too that in the latter case the location of your template must be a symbol, not a string, e.g.
rabl :'foos/index', :format => "json"
Now just add a template of type .rabl to match the template referenced in your route to be rendered. For instance, in this case the name of the template is
# views/foo.json.rabl object @foo # Declarations here
And you're done! Now that's what I call easy.
