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

问题描述

有谁知道或可以请任何人制作 Django 基于类的通用 DeleteView 的简单示例?我想继承 DeleteView 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.任何帮助将不胜感激.提前致谢.

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.

推荐答案

这是一个简单的方案:

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

注意事项:

• DeleteView 不会删除 GET 请求；这是您提供带有是的，我确定"按钮的确认模板(您可以在 template_name 类属性中提供名称)的机会，该按钮POSTs 到此查看
• 与 404 相比，您可能更喜欢错误消息?在这种情况下，改写 delete 方法，在 get_object 调用后检查权限并返回自定义响应.
• 不要忘记提供与(可选可自定义)success_url 类属性匹配的模板，以便用户可以确认对象已被删除.

• 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.
