Return json at create new row at database in Ruby On Rails

Question

Hi everyone i am making an app with a backend in rails, i need to create a user from an ajax request and the server have to return a json object with the new user saved.

This is my code of rails

class UsersController < ApplicationController

   def nuevo_usuario
      @u = User.new(params[:user])
      @u.save       
      respond_to do |format|
          format.json { render :json => @u }
      end
    end

end

And this is the code of javascript

$.post("http://0.0.0.0:3000/users/nuevo_usuario.json", $("#resgistro-form").serialize(), function(data){});

And the server respond with this

Started POST "/users/nuevo_usuario.json" for 127.0.0.1 at 2013-06-14 10:17:22 -0500
Processing by UsersController#nuevo_usuario as JSON
  Parameters: {"user"=>{"user"=>"prueba", "mail"=>"prueba@gmail.com", "password"=>"[FILTERED]"}}

I don't receive the json object that i send with rails.

Are you looking at only the log file? That won't include the actual response body.

I look for the response body with firebug and is empty, i start to think that is something about the crossdomain ajax request – kentverger Jun 14 '13 at 15:40

Add "respond_to :json"

So that it is something like:

class UsersController < ApplicationController
       respond_to :json

   def nuevo_usuario
      @u = User.new(params[:user])
      @u.save       
      respond_to do |format|
          format.json { render :json => @u.as_json }
      end
    end

end

i add respond_to :json before the nuevo_usuario method and didn't work, i also try with removing respond_to code block and replace it with respond_with function that i found here http://stackoverflow.com/questions/8200929/how-to-convert-this-respond-to-options-to-use-rails-3-version but dont work :( – kentverger Jun 14 '13 at 15:58

I upload my code to heroku and complied the app with phongap and it works fine, i think that the problem was crossdomain and crossbrowser ajax request
