我想在 Devise 的用户注册中添加一个商店。

让我解释一下：在注册页面上，用户可以选中一个框“立即创建我的商店”。如果他检查，就会显示一个表格供他填写。然后他提交表单，User + Shop 创建。我想知道控制器“UsersController”中的最佳方法，以及模型和视图。

谢谢您的帮助

您可以使用 Accepts_nested_attributes_for 和嵌套模型来执行此操作。

简单结帐

更新：

将商店属性添加到表单（使用 fields_for => accept_nested_attributes_for），隐藏这些表单字段。在您的用户模型中创建一个 attr_accessor，例如名为 :create_shop_now，将其添加到您的表单中。如果 :create_shop_now 被选中，则显示商店表单字段..用户可以填写这些字段。用户将表单提交给创建操作。创建操作可能如下所示：

def create
  build_resource

  if !params[:user][:create_show_now]
    params[:user].delete(:shops_attributes)
  end

  if resource.save
    if resource.active_for_authentication?
      set_flash_message :notice, :signed_up if is_navigational_format?
      sign_up(resource_name, resource)
      respond_with resource, :location => after_sign_up_path_for(resource)
    else
      set_flash_message :notice, :"signed_up_but_#{resource.inactive_message}" if is_navigational_format?
      expire_session_data_after_sign_in!
      respond_with resource, :location => after_inactive_sign_up_path_for(resource)
    end
  else
    clean_up_passwords resource
    respond_with resource
  end
end

更新2

删除模型中的 after_initialize 钩子并将您的 registrations#new 操作更新为以下内容：

def new
  resource = build_resource({})
  resource.shops.build
  respond_with resource
end
