传递用户,请求表单

Question

如何将用户对象或请求传递给表单进行验证？

例如,我希望能够做到这样的事情 -

class Form(forms.Form):
    ...
    def clean(self)
        user = request.user   # how to get request.user here?
        user = User           # how to pass the actual User object?

谢谢.

只需将其传递给构造函数并将其存储为实例变量:

class MyForm(forms.Form):
    def __init__(self, *args, **kwargs):
        self.request = kwargs.pop("request")
        super(MyForm, self).__init__(*args, **kwargs)

    def clean(self):
        print self.request.user
        ...

在你看来:

form = MyForm(..., request=request)

如果使用基于类的视图(在此示例中为CreateView):

class MyCreateView(CreateView):

    ... 

    def get_form_kwargs(self):
        kwargs = super(MyCreateView, self).get_form_kwargs()
        kwargs.update({'request': self.request})
        return kwargs
