How to pass request to django form?

How to pass request to django form?

I am creating a django update profile form where user could change profile email. I want to check if email in form belongs to logged user if not then I want to check if this email is used by others users before setting it as new users email.

Here is my code and this self.request.user.email doesn't work:

def clean_email(self):
        email = self.cleaned_data.get("email")
        owns_email = (email != self.request.user.email)
        if User.objects.filter(email__icontains=email).exists() and owns_email:
            raise forms.ValidationError("This email aldready registered.")
        return email

So maybe there is better solution to solve my problem?

Since you are using a cbv, you can use the get_form_kwargs function from the FormMixin.

It could look something like this:

class UserProfileUpdateView(UpdateView):
...
    def get_form_kwargs(self):
    '''This goes in the Update view'''
        kwargs = super(UserProfileUpdateView, self).get_form_kwargs() #put your view name in the super
        user = self.request.user

        if user:
            kwargs['user'] = user

        return kwargs

Then your form class would look something like this, based on your above code:

class UserProfileUpdateForm:
...
    def __init__(self, *args, **kwargs):
        if kwargs.get('user'):
            self.user = kwargs.pop('user', None)
        super(UserProfileUpdateForm, self).__init__(*args,**kwargs)

    def clean_email(self):
        email = self.cleaned_data.get("email")
        owns_email = (email != self.user.email)
        if User.objects.filter(email__icontains=email).exists() and owns_email:
            raise forms.ValidationError("This email already registered.")
        return email

The form doesn't have the Request object. You need to manually pass the currently logged in user in the constructor. Your form should look something like this:

class UserProfileForm(forms.Form):
    user = None

    def __init__(self, *args, **kwargs):
        self.user = kwargs.pop('user')
        super(UserProfileForm, self).__init__(*args, **kwargs)

    ...
    def clean_email(self):
        email = self.cleaned_data['email']
        owns_email = (email != self.user.email)
        if User.objects.filter(email__icontains=email).exists() and owns_email:
            raise forms.ValidationError('This email already registered.')
        return email
    ...

Instantiating the form in the view:

def edit_profile(request):
    form = UserProfileForm(user=request.user)
    ...
