在关联时使用class_name时的accepts_nested_attributes_for

以下是代码:

User.rb

class User < ActiveRecord::Base
    # So we can reference the user's Client information with user.as_client
    has_one :as_client, :class_name => 'ClientAccount'
    accepts_nested_attributes_for :as_client
end

form.html.erb

<%= f.label :first_name %>
<%= f.text_field :first_name %>

<%= f.fields_for :as_client do |c| %>
  <%= c.label :website %>
  <%= c.text_field :website %>
<%= end %>

现在,当我提交表单时,这就是发送的内容:

{"user"=>{"first_name"=>"Name", "as_client_attributes"=> "website"=>"http://website.com"}}, "commit"=>"Update User"}

我收到了这个错误:

Can't mass-assign protected attributes: as_client_attributes

我该如何使这项工作?谢谢!

您需要在用户模型中添加attr_accessible :as_client_attributes,以便通过accepts_nested_attributes_for批量分配属性。
