在Django源代码中,post()方法对DeletionMixin做了什么?

我正在学习Django,并试图理解它 DeleteView 来自第一校长。

在 source code 对于 DeletionMixin 两者都有一个共同点 delete 方法和步骤 post 方法:

class DeletionMixin:
    """Provide the ability to delete objects."""
    success_url = None

    def delete(self, request, *args, **kwargs):
        """
        Call the delete() method on the fetched object and then redirect to the
        success URL.
        """
        self.object = self.get_object()
        success_url = self.get_success_url()
        self.object.delete()
        return HttpResponseRedirect(success_url)

    # Add support for browsers which only accept GET and POST for now.
    def post(self, request, *args, **kwargs):
        return self.delete(request, *args, **kwargs) 

这两种方法的区别是什么?它们在什么时候被调用?

是吗 delete() 方法仅在 request.GET ?

如果 删除() 方法也定义在 models.Model 类执行不同的操作,重写 删除mixin 在视野里还是别的什么?

例如:

class MyModel(models.Model):
    def delete(self):
        ...
        return

你能帮我理解一下在什么时候发生的事情的逻辑“工作流程”吗 删除视图 被称为。

相关类结构如下:

class BaseDeleteView(DeletionMixin, BaseDetailView):
    pass


class DeleteView(SingleObjectTemplateResponseMixin, BaseDeleteView):
    template_name_suffix = '_confirm_delete'
