mysql - 如果用户创建，Rails 会创建记录

Question

如果新用户注册，会自动为他创建一个 job_app 状态。整个数据库位于mysql上，我与用户模型中的问题没有任何关系(仅验证和has_one)问题是job_apps中带有user_id的新记录= current_user.user_id 不会创建(我真的不知道该怎么做)。

class UsersController < ApplicationController
    include job_apps_helper
    def new
        @users = User.new
    end

    def create
        @user = User.new(user_params)
        if @user.save 
            session[:user_id] = @user.id 
            current_user = @user.id

            redirect_to '/status' 
        else 
            redirect_to '/signup' 
        end 
    end
    private
        def user_params
        params.require(:user).permit(:first_name, :last_name, :email, :PESEL, :phone, :cv, :password)
        end
end


class JobAppsController < ApplicationController
    before_action :require_user, only: [:index]
    before_action :require_emp, only: [:empl]
    #def new 
    #   @job_app = job_app.new
    #end

    def index 
        @users = User.includes(:job_apps)
        end
        def empl
            @users = User.all.where(:user_type => 'candidate')
        end

    end
class JobApp < ActiveRecord::Base
    belongs_to :user dependent: :create, :destroy
    enum status: [ :waiting, :accepted , :refused  ]
    def accept 
        self.update(status: 1)
    end
    def refuse
        self.update(status: 2)
    end
    end
end

我的路线:

root 'stat_page#home'
    get 'status' => 'job_apps#index'
    get 'stat_emp' => 'job_apps#empl'
    get 'login' => 'sessions#new'
    post 'login' => 'sessions#create'
    delete 'logout' => 'sessions#destroy'
    get 'logout' => 'sessions#destroy'
    get 'signup' => 'users#new'
    resources :users

您应该使用 callback在您的用户模型上。

class User < ActiveRecord::Base
  after_save :create_job_app

  def create_job_app
    JobApp.create(status: 0, user_id: self.id)
  end
end
