传递用户，请求表单 [英] Passing a user, request to forms

问题描述

我如何将用户对象或请求传递给我的表单以进行验证?

How would I pass a user object or a request to my form for validation?

例如，我希望能够做这样的事情 --

For example, I want to be able to do something like this --

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.

推荐答案

只需将其传入构造函数并将其存储为实例变量即可:

Just pass it into the constructor and store it as an instance variable:

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
        ...

在您看来:

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

如果使用基于类的视图(本例中为 CreateView):

And if using a class-based view (a CreateView in this example):

class MyCreateView(CreateView):

    ... 

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