rails after_create 未更新父模型

Question

使用从此解决方案获得的相同方法：

Use both Account and User tables with Devise

我正在尝试在保存用户后更新帐户模型上的 owner_id 列：

账户模型

class Account < ActiveRecord::Base
  has_many :users
  has_secure_token

  accepts_nested_attributes_for :users

  validates :name, :presence => true
end

用户模型

class User < ActiveRecord::Base

  after_create :set_account_owner_id
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable

  belongs_to  :account

  validates :name, :presence => true

  protected

  def set_account_owner_id
    self.account.owner_id = self.id
    self.account.save
  end

end

账户管理员

class AccountsController < ApplicationController

  def new
    # Create a new Account and then update owner_id with User profile id
    @account = Account.new
    @account.users.build
  end

  def create
    @account = Account.new(account_params)
    if @account.save
      flash[:success] = "Account successfully created!"
      redirect_to accounts_path
    else
      render 'new'
    end
  end

  private

  def account_params
    params.require(:account).permit(:name, :token, :token_flag, :owner_id, users_attributes: [:name, :email, :password, :password_confirmation, :role])
  end

end

Rspec 测试

RSpec.describe Account, type: :model do
  it "should create an Account and a User through accepts_nested_attributes_for" do
    @accountuser = {
      :name => "My App Name",
      :users_attributes => [{
          :name     => "John Doe",
          :email    => "jdoe@email.com",
          :password => "password",
          :password_confirmation => "password",
          :role => "dev",
        }]
      }

    account = Account.create!(@accountuser)
    account.owner_id.should == account.users[0].id
  end
end

测试失败并出现以下错误：

1) Account should create an Account and a User through accepts_nested_attributes_for
     Failure/Error: account.owner_id.should == account.users[0].id
       expected: 1
            got: nil (using ==)

在阅读其他线程时，我认为问题是由于我没有在 after_create 中调用 'save'，但是，我一直得到相同的结果。

如有任何见解，我们将不胜感激。

在 after_create 回调中，不保证您会有一个记录 ID。请改用 after_commit on: create。

所以，不要调用 after_create :set_account_owner_id，而是调用：

after_commit :set_account_owner_id, on: :create

此外，如果您使用 after_commit 测试代码，请记住添加 test_after_commit gem。来自 after_commit doc:

Note that transactional fixtures do not play well with this feature. Please use the test_after_commit gem to have these hooks fired in tests.
