Django Password Reset Confirm error (custom user model); update - django

Question

I am not that experienced writing Python/Back-end, but trying to improve. In development/localserver I am trying to create a password reset form... but I got the following error when accessing the link from the forgot password email - and before that the password was not saving:
init() missing 1 required positional argument: 'user'
forms.py (almost copy/paste from Django's form; minor changes)
class ResetPasswordForm(SetPasswordForm):
error_messages = {
'password_mismatch': static_textLanguage['page_user_passwordReset_alert_passwordNotMatch'],
'password_empty': static_textLanguage['global_alert_mandatoryField'],
'minimum_length': static_textLanguage['global_alert_minCharacters_password'],
}
new_password1 = forms.CharField(
required=False,
widget=forms.PasswordInput(attrs={
'id': 'page_userPasswordReset_content_form_input_passwordA',
'maxlength': '25',
'class': 'global_component_input_box'
}),
)
new_password2 = forms.CharField(
required = False,
widget=forms.PasswordInput(attrs={
'id': 'page_userPasswordReset_content_form_input_passwordB',
'maxlength': '25',
'class': 'global_component_input_box'
}),
)
def __init__(self, user, *args, **kwargs):
self.user = user
super(ResetPasswordForm, self).__init__(user, *args, **kwargs)
def clean_new_password1(self):
password1 = self.cleaned_data.get('new_password1')
if password1 == '' or password1 is None:
raise forms.ValidationError(self.error_messages['password_empty'], code='password_field_empty')
elif len(password1) < 8:
raise forms.ValidationError(self.error_messages['minimum_length'], code='password_too_short')
return password1
def clean_new_password2(self):
password1 = self.cleaned_data.get('new_password1')
password2 = self.cleaned_data.get('new_password2')
if password2 == '' or password2 is None:
raise forms.ValidationError(self.error_messages['password_empty'], code='password_field_empty')
if password1 and password2:
if password1 != password2:
raise ValidationError(self.error_messages['password_mismatch'], code='password_mismatch')
password_validation.validate_password(password2, self.user)
return password2
def save(self, commit=True):
password = self.cleaned_data["new_password1"]
self.user.set_password(password)
if commit:
self.user.save()
return self.user

Answer 1

The error most likely happens because you defined user as positional argument (def __init__(self, user, *args, **kwargs):), but you pass the variable as a keyword argument (kwargs['user'] = self.user).
Instead of your code:
class ResetPasswordForm(SetPasswordForm):
...
def __init__(self, user, *args, **kwargs):
self.user = user
...
try changing it to this (so that the ResetPasswordForm looks for the user inside kwargs):
class ResetPasswordForm(SetPasswordForm):
...
def __init__(self, *args, **kwargs):
self.user = kwargs['user']
...
