Rails Devise-向关联模型注册用户 [英] Rails Devise - Register User with Associated Model

问题描述

我在此主题上遇到了一些SO问题，但似乎都过时了或仅仅是不好的编码习惯。

I've come across a few SO questions on this topic, but all seem out of date or simply bad coding practice.

问题：我正在向用户注册，这是结帐流程的一部分。我想在用户注册时收集用户的地址。我有一个用户模型和一个地址模型。我似乎无法弄清楚如何正确地覆盖Devise的注册控制器以允许其他参数。

Problem: I am signing up a user as part of a checkout flow. I want to collect the user's address when they sign up. I have a user model and an address model. I can't seem to figure out how to properly override Devise's registration's controller to allow the additional params.

这就是我开始的目的：

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable

  has_many :orders
  has_many :addresses, :dependent => :destroy

  accepts_nested_attributes_for :addresses

end

我也有我的地址模型：

class Address < ActiveRecord::Base
  belongs_to :state
  belongs_to :user
end

...在routes.rb中：

...in routes.rb:

   devise_for :users, controllers: {registrations: 'registrations'}

最后，我试图覆盖设计注册的控制者：

And finally, my attempt at overriding the devise registration's controller:

class RegistrationsController < Devise::RegistrationsController

  before_filter :configure_permitted_parameters

  # GET /users/sign_up
  def new

    # Override Devise default behaviour and create a profile as well
    build_resource({})
    resource.build_address
    respond_with self.resource
  end

  protected

  def configure_permitted_parameters
    devise_parameter_sanitizer.for(:sign_up) { |u|
      u.permit(:email, :password, :password_confirmation, :address_attributes => [:address, :address2, :city, :state_id, :zip_code])
    }
  end
end

推荐答案

在您的application_controller.rb中

In your application_controller.rb

class ApplicationController < ActionController::Base
before_action :configure_strong_params, if: :devise_controller?

  def configure_strong_params
  devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:username, :name, 
    :addresses_attributes => [:address, :address2, :city, :state_id, :zip_code]) }
  end
end

现在，您可以在注册表格中使用address_attributes&设计注册参数将接受这一点。

Now in your registration form you can use address_attributes & devise signup params will accept this.

现在要停止从过滤器链中恢复，请在您的 registrations_controller.rb 文件中尝试此操作

Now to rescue from the filter chain halted, please try this in your registrations_controller.rb file

class RegistrationsController < Devise::RegistrationsController
 skip_before_filter :require_no_authentication, only: :create
 #other codes 
end
