推荐答案

Ber 的答案 - 将其存储在 threadlocals - 是一个非常糟糕的主意.绝对没有理由这样做.

The answer by Ber - storing it in threadlocals - is a very bad idea. There's absolutely no reason to do it this way.

更好的方法是覆盖表单的 __init__ 方法以采用额外的关键字参数 request.这会将请求存储在表单中，在需要它的地方，以及您可以在干净的方法中从哪里访问它.

A much better way is to override the form's __init__ method to take an extra keyword argument, request. This stores the request in the form, where it's required, and from where you can access it in your clean method.

class MyForm(forms.Form):

    def __init__(self, *args, **kwargs):
        self.request = kwargs.pop('request', None)
        super(MyForm, self).__init__(*args, **kwargs)


    def clean(self):
        ... access the request object via self.request ...

在您看来:

myform = MyForm(request.POST, request=request)
