Question

我正在使用Rails 5.2.2。我正在尝试通过devise使用嵌套属性。我创建了关联，迁移和视图。

这是我的路线。rb：

Rails.application.routes.draw do
  devise_for :users
  resources :companies, :has_many => :users
  get 'welcome/index'
  root "welcome#index"
end

User.rb：

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

  belongs_to :company
  accepts_nested_attributes_for :company

end

Company.rb：

class Company < ApplicationRecord
    has_many :users
end

我的自定义设计参数引起关注：

module DevisePermitter
    extend ActiveSupport::Concern

    included do 
        before_action :permitted_devise_parameters, if: :devise_controller?

    end



    def permitted_devise_parameters
        devise_parameter_sanitizer.permit(:sign_up, keys: [:name,:gsm,:role,:company_id,company_attributes:[:name,:tax_no,:city]])
        devise_parameter_sanitizer.permit(:account_update, keys: [:name,:gsm,:id_no,:profile_picture,:socials])
    end
end

当我单击提交按钮时，它将返回相同的sign_up页面，而不记录值。这是服务器响应：

Started GET "/users/sign_up?utf8_SHORTENED-HERE" for 127.0.0.1 at 2018-12-26 10:32:51 +0300

  Rendered devise/registrations/new.html.erb within layouts/devise1 (3.4ms)
Completed 200 OK in 19ms (Views: 17.7ms | ActiveRecord: 0.0ms)

当我尝试使用Rails控制台保存数据时，它会起作用：

User.create!({"email"=>"asd@yandex.com", "password"=>"[FILTERED]", "password_confirmation"=>"[FILTERED]", "company_attributes"=>{"name"=>"asdasd", "tax_no"=>"asdasd", "city"=>"asdasd"}, "name"=>"asdasd asd", "gsm"=>"313121", "role"=>"asdasd"})

我正在传递某些东西，但是我找不到它。

Answer 1

在/app/controllers/application_controller.rb

中尝试类似的操作

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

    protected
    def permitted_devise_parameters
        devise_parameter_sanitizer.permit(:sign_up, keys: [:name,:gsm,:role,:company_id,company_attributes:[:name,:tax_no,:city]])
        devise_parameter_sanitizer.permit(:account_update, keys: [:name,:gsm,:id_no,:profile_picture,:socials])
    end
end

并注释掉DevisePermitter中的代码，看看会发生什么

Answer 2

我发现了问题。问题出在我看来，form_for标记未在表单元素中生成action =“ \ users”和method =“ post”。

通过创建有效的form_for标签来解决。

Answer 3

从allowed_devise_parameters方法中删除company_id。

def permitted_devise_parameters
    devise_parameter_sanitizer.permit(:sign_up, keys: [:name,:gsm,:role, company_attributes:[:name,:tax_no,:city]])
    devise_parameter_sanitizer.permit(:account_update, keys: [:name,:gsm,:id_no,:profile_picture,:socials])
end

Rails提交按钮未保存数据
