I have a rails app which works as an api, here my controller:

class CarController < ApplicationController
  def create
    @car = Car.new(params[:car])
    if @car.save
      render json: @car, status: :created, location: @car
    else
      render json: @car.errors, status: :unprocessable_entity
    end
  end
end

I want to "call" this create function from my angular app, here my angular factory

angular_app.factory('api', function($http) {
    $http.defaults.headers.common['X-CSRF-Token'] = $('meta[name=csrf-token]').attr('content');
    $http.defaults.headers.post["Content-Type"] = "application/x-www-form-urlencoded";

    return {
   //car looks like {owner:'Andres', year:'2014', ....} with every field of Car model
            SaveCar: function(car) {
                return $http.post('/car/', {car:car}).then(function(result) {
                    return result;
                })
            }
        }
});

The problem is that in my create car function I get someting like this:

{"{\"car\":{\"owner\":\"andres\",\"year\":\"2014\",....}}"=>nil, "action"=>"create", "controller"=>"car"}

just an string, and it should be:

{"car" => {"owner"=>"andres", "year":"2014", ....}, "action"=>"create", "controller"=>"task"}

What is my mistake here? I tried to use JSON.parse but didn't work.

Maybe problem in strong parameters. So instead of params[:car] use params.require(:car).permit!. But it throw another error in this case. All seems ok. Except there is no routes for this request. –  zishe May 27 '14 at 23:33
    
@zishe tried that and got ActionController::ParameterMissing (param is missing or the value is empty: car): –  Andres May 27 '14 at 23:36
    
Perhaps that car in angular part is a string, not object. log it. –  zishe May 27 '14 at 23:39
    
string? I created as follow: var car = {owner:"Andres", year:"2014", ....} –  Andres May 27 '14 at 23:41

Got it:

def create
    @car = Car.new(JSON.parse(request.body.read)['car'])

    if @car.save
        render json: @car, status: :created, location: @car
    else
        render json: @car.errors, status: :unprocessable_entity
    end
end

It works, but I don't really know what request.body.read does. Feel free to edit it and explain(remember, I'm starting with ruby)
