Rails store data JSONP

Say if I did a simple scaffold like rails g scaffold user name:string . How would I go through the controller and make the data as jsonp rather than json

EDIT: See Ashley Williams Answer!

JSONP is just wrapping the JSON object in a function call. So something like this

UsersController:

def index
  @callback_func_name = params[:callback]
  @users = User.all
end

View named index.js.erb:

<%= @callback_func_name %>(<%= @users.to_json %>)

Then the request you issue is:

http://localhost.com:3000/users.js?callback=myfunction

The details might not be exactly right, but this should get you most of the way there, let me know if you have any questions.

Rails 3 actually allows you to pass a callback option to render now:

def index
  render json: @users.to_json, callback: params[:callback]
end

Which would be available at:

http://0.0.0.0:3000/users.json?callback=foobar
