Python 为什么BaseDeleteView抛出一个属性错误，说对象没有属性render\u to\u响应？

我正在尝试实现BaseDeleteview，但获取此错误消息->“DeletePostView”对象没有“render_to_response”属性，我没有使用DeleteView，主要是因为它需要一个确认模板，我使用bootraps的模式（如弹出窗口）进行确认

我在这里发现了很多类似的问题->

回溯错误：

因为

BaseDeleteView

有一个

get

方法，它的主体中会调用另一个名为

self.render\u to\u response（context）

的方法。此方法将来自名为

TemplateResponseMixin

的内置mixin，由于您使用了

BaseDeleteView

，因此此方法不存在，它将引发错误。因此，您应该覆盖以下视图的

get

方法：

def get(self, request, *args, **kwargs):
    self.object = self.get_object()
    context = self.get_context_data(object=self.object)
    return self.render_to_response(context)

类似于此或您需要的任何类型：

from django.shortcuts import render

# override get method of your DeletePostView
def get(self, request, *args, **kwargs):
    self.object = self.get_object()
    context = self.get_context_data(object=self.object)
    return render(request, 'your_template.html', context=context)

---

或者，您可以在

DeletePostView

父视图中添加

SingleObjectTemplateResponseMixin

（即来自django.views.generic import SingleObjectTemplateResponseMixin）以将此功能添加到视图中，并覆盖任何自定义它的方法（与

DeleteView

相同）.

您是否发布或获取删除端点？这是一个get请求@iriYes，您是对的，但我的目标是避免最终被调用的确认模板，无论我使用哪种方法。所以，使用了某种技巧来避免模板。基本上，在模板中，我创建了一个表单，其属性仅为button，并使用POST请求调用DeletePostView。这解决了我的问题。另外，我从DeleteView继承了DeletePostView。

from django.shortcuts import render

# override get method of your DeletePostView
def get(self, request, *args, **kwargs):
    self.object = self.get_object()
    context = self.get_context_data(object=self.object)
    return render(request, 'your_template.html', context=context)
