Question

我有一个用户和帐户模型，其中包含 has_one 关联和嵌套属性。
我的问题是，当通过Devise注册用户时，不会创建帐户，也不会在日志中生成错误。我正在使用Rails 3.2和Devise 2.0.4。

user.rb

class User
  include Mongoid::Document

  has_one :account, :inverse_of => :user

  accepts_nested_attributes_for :account

  field :name
  validates_presence_of :name
  validates_uniqueness_of :name, :email, :case_sensitive => false
  attr_accessible :name, :email, :password, :password_confirmation, :remember_me, :account_attributes

  devise :database_authenticatable, :registerable,
     :recoverable, :rememberable, :trackable, :validatable
  ...
end

account.rb

class Account
  include Mongoid::Document

  belongs_to :user, :inverse_of => :account

  field :name

  validates_presence_of :user
  attr_accessible :name, :user_id

end

registration_controller.rb

class RegistrationsController < Devise::RegistrationsController
  def new
    resource = build_resource({})
    resource.build_account
    respond_with resource
  end
end

查看

<h2>Sign up</h2>

<%= form_for(resource, :as => resource_name, :url => registration_path(resource_name)) do |f| %>
  <%= devise_error_messages! %>

  <%= f.fields_for :account do |account_form| %>
    <div><%= account_form.label 'Company' %>
    <%= account_form.text_field :name %></div>
  <% end %>
...

这是我的控制台输出

如您所见，我看不到有关创建帐户的任何信息。还验证了通过查看MongoDB没有创建帐户集合。我错过了什么？提前感谢您的帮助。

解决了这个问题我需要打开：自动保存

has_one :account, :inverse_of => :user, :autosave => true

mongoid docs指出了这个问题。

请注意：如果您不想在更新时手动保存关系，则需要为neighbor_nested_attributes_for使用的关系关联启用：autosave选项。

使用嵌套属性设计注册不会创建关联
