Question

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“立即创建我的商店”框。如果他检查，则显示一个表格，他可以填写表格。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。

感谢您的帮助

更新：这是我的代码

Answer 1

您可以使用accepts_nested_attributes_for和嵌套模型执行此操作。

简单结帐

<强>更新

将商店属性添加到表单（使用fields_for =＆gt; accepts_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：create_shop_now，将其添加到您的表单中。 if：create_shop_now被选中，显示商店表单字段。用户可以填写字段。 user将表单提交给create动作。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

<强> UPDATE2

删除模型中的after_initialize挂钩，并将注册#new action更新为以下内容：

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