Question

我正在创建一个包含用户和帐户的应用程序。我的问题是我首先创建了用户模型和身份验证功能，但后来意识到我需要让用户属于帐户。

如果我在路线http://lvh.me:3000/signup注册用户，它将创建新用户，发送激活电子邮件并激活用户。除了没有创建Account之外，效果很好。但现在，我需要在混合中添加account。如果我在我的新路线http://lvh.me:3000/accounts/new注册，它将创建帐户和用户，但我需要发送激活电子邮件，以便我可以实际激活用户。我似乎无法让我的Account控制器在@user.send_activation_email内的create操作中触发UserController - 请参阅下面的代码。我知道下面的方式不是正确的方法，但是我碰到了一堵砖墙，不知道从哪里开始。

user.rb

class User < ApplicationRecord
  has_many :memberships
  has_many :accounts, through: :memberships
  accepts_nested_attributes_for :accounts
  ...
   # Sends activation email.
  def send_activation_email
    UserMailer.account_activation(self).deliver_now
  end
  ...

account.rb

class Account < ActiveRecord::Base
  belongs_to :owner, class_name: 'User'
  accepts_nested_attributes_for :owner

  has_many :memberships
  has_many :users, through: :memberships
end

accounts_controller.rb

class AccountsController < ApplicationController

  def new
    @account = Account.new
    @account.build_owner
  end

  def create
    @account = Account.new(account_params)
    if @account.save
      @user.send_activation_email
      flash[:info] = 'Please check your email to activate your account.' # Use this for registered users
      # flash[:info] = 'Please have user check their email to activate their account.' # Use this for admin created users
      redirect_to root_url
    else
      flash.now[:alert] = 'Sorry, your account could not be created.'
      render :new
    end
  end

  private

  def account_params
    params.require(:account).permit(:organization, owner_attributes: [:name, :email, :password, :password_confirmation])
  end
end

users_controller.rb

class UsersController < ApplicationController
   ...
    def create
    @user = User.new(user_params)
    if @user.save
      @user.send_activation_email
      flash[:info] = 'Please check your email to activate your account.' # Use this for registered users
      # flash[:info] = 'Please have user check their email to activate their account.' # Use this for admin created users
      redirect_to root_url
    else
      render 'new'
    end
  end
  ...
  def user_params
    params.require(:user).permit(:name, :email, :password, :password_confirmation, accounts_attributes: [:organization])
  end
  ...

如果您需要在注册流程中创建两个模型，则在单个控制器中执行单个操作，以触发注册流并创建两个记录。

您可以通过多种方式实现此目的，例如让Users#signup操作创建用户和事务中的帐户，或者您可以将该逻辑移出控制器并进入模型层并提供User.signup方法，可以明确地或在after_create回调中创建帐户。

无论哪种方式，此处的修复方法是简化和统一您的注册流程，而不是将其拆分为多个控制器。如果您有某种需要用户在步骤之间执行某些操作的多步注册，您只需要这样做。
