Working With Rails

Json Request

The plugin adds a MIME parser that parses requests with the content type application/json, and maps them to a request parameter using the controller name as guidance.

class ItemsController < ApplicationController 

def show
  respond_to do |format|
    format.json :json=>@item
    format.xml  :xml=>@item
  end
end

def update
  @item.update_attributes! params[:item]
  show
end

end

It works the same way whether you feed it an XML document, JSON object, or URL-encoded parameters.

Since the JSON object is not annotated, it figures out the parameter name based on the controller name, in this case ItemsController becomes item. If you prefer a different name, add this line to your controller:

json_request :itemz

The json_request method adds a filter and can take the only and except options, if you need to limit it to specific actions.
