What is causing the 500 (Internal Server Error) error?

Question

Ruby on Rails

I am writing a small CRUD application using Rails/Angular.
WHEN I try to create or update data, 500 (Internal Server Error) pops up
, I use gem 'inherited_resources' so as not to write all the actions myself!
this is my controller

class ProductsController < InheritedResources::Base
  respond_to :json
end

But when all the actions in the controller are written manually, everything works!!!
What could be the reason???

Answer 1

added the following to the controller

private
    def permitted_params
      params.permit(:product => [:name, :description, :price])
    end

and everything worked
