Hi
How To set init data for form_class in djangoformmutation ? I try to use django auth forms PasswordChangeForm and this form need 'user' instance in init. So djangoformmutation crash in init_subclass_with_meta execution

DjangoFormMuation has a method: def get_form_kwargs(cls, root, info, **input) ; this is what you want to override, have it return a dictionary with the desired keyword arguments to be passed to the form init.

You can do something like this:

from django.contrib.auth.forms import PasswordChangeForm
from graphene_django.forms.mutation import DjangoFormMutation


class MyPasswordChangeForm(PasswordChangeForm):
    def __init__(self, *args, **kwargs):
        user = kwargs.pop('user', None)
        super().__init__(user, *args, **kwargs)


class ChangePassword(DjangoFormMutation):
    class Meta:
        form_class = MyPasswordChangeForm

    @classmethod
    def get_form_kwargs(cls, root, info, **mutation_input):
        return {**super().get_form_kwargs(root, info, **mutation_input), 'user': info.context.user}
