如何将devise与rails 4一起用于在第二个模型上存储数据？

Question

There are some similar questions but not clear answer. I want to use devise I was able to add more fields and store them on the user table. If I want to collect data during the signup process that belong to another table is it possible to do it through devise controller or do I have to write my own one ?

Answer 1

You have to use your own. Override the registrations controller and add it to your routes to point your devise registration to your new registrations controller.

# app/controllers/registrations_controller.rb
class RegistrationsController < Devise::RegistrationsController
  def new
    super
  end

  def create
    # add custom create logic here
    # Strip the fields out of the resource params and save them to 
    # another model then you can call super to have the method behave as it normal:
    super
  end

  def update
    super
  end
end 

Then add it to your routes

# app/config/routes.rb
devise_for :users, :controllers => {:registrations => "registrations"}

Depending on how you're structuring your form you might need to add the extra fields to the devise model (typically User ) - you can use attr_accessor :field_name to do this if you must
