基于Django类的DeleteView示例 [英] Example of Django Class-Based DeleteView

问题描述

有没有人知道或可以任何人制作一个简单的Django类的通用DeleteView示例？我想对DeleteView进行子类化，并确保当前登录的用户在删除对象之前拥有该对象的所有权。任何帮助将非常感谢。谢谢你提前。

解决方案

这是一个简单的例子：

<$ p来自django.views.generic导入的$ p> 从django.http导入DeleteView
导入Http404

class MyDeleteView（DeleteView）：
def get_object（self， queryset = None）
Hook保证对象由request.user拥有。
obj = super（MyDeleteView，self）.get_object（）
如果不是obj。所有者== self.request.user：
raise Http404
return obj


注意事项：

• DeleteView 不会在 GET 请求;这是您提供确认模板的机会（您可以在 template_name 类属性中提供名称），其中包含是我确定按钮，其中 POST 到此视图


• 您可能希望向404发送错误消息？在这种情况下，请重写 delete 方法，在 get_object 调用后检查权限，并返回自定义响应。 li>
  
• 不要忘记提供与（可选择定制的） success_url 类属性匹配的模板，以便用户可以确认对象具有已被删除。

Does anyone know of or can anyone please produce a simple example of Django's class-based generic DeleteView? I want to subclass DeleteView and ensure that the currently logged-in user has ownership of the object before it's deleted. Any help would be very much appreciated. Thank you in advance.

解决方案

Here's a simple one:

from django.views.generic import DeleteView
from django.http import Http404

class MyDeleteView(DeleteView):
    def get_object(self, queryset=None):
        """ Hook to ensure object is owned by request.user. """
        obj = super(MyDeleteView, self).get_object()
        if not obj.owner == self.request.user:
            raise Http404
        return obj

Caveats:

• The DeleteView won't delete on GET requests; this is your opportunity to provide a confirmation template (you can provide the name in the template_name class attribute) with a "Yes I'm sure" button which POSTs to this view
• You may prefer an error message to a 404? In this case, override the delete method instead, check permissions after the get_object call and return a customised response.
• Don't forget to provide a template which matches the (optionally customisable) success_url class attribute so that the user can confirm that the object has been deleted.
