django-registration アプリを使用しています。そしてforms.pyに次のコードがあります
from django.contrib.auth.forms import UserCreationForm
from registration.forms import RegistrationFormUniqueEmail
from django import forms
from django.contrib.auth.models import User
from accounts.models import UserProfile
from pprint import pprint

fields = ("fullname", "email", )

super(UserRegistrationForm, self).__init__(*args, **kwargs)
del self.fields['username']

user = super(UserRegistrationForm, self).save(commit=False)
user.userprofile.full_name = self.cleaned_data["fullname"]
user.email = self.cleaned_data["email"]
if commit:
user.save()
return user
私はDjango-registraionアプリのクラスRegistrationFormUniqueEmailから継承したので、saveメソッドを呼び出すuser = super(UserRegistrationForm, self).save(commit=False)と、save属性が存在しないと言います。私は実際に からの継承でこのコードを書きましたUserCreationForm。次のRegistrationFormUniqueEmailのSuperClassのコメントを読みました。
"""
Form for registering a new user account.
Validates that the requested username is not already in use, and
requires the password to be entered twice to catch typos.
Subclasses should feel free to add any additional validation they
need, but should avoid defining a ``save()`` method -- the actual
saving of collected user data is delegated to the active
registration backend.
"""
これらのコメントは、別の保存方法を定義しないように求めていますが、私はそうする必要があります。保存メソッドを定義し、親保存メソッドを呼び出して追加のフィールドを定義する方法はありますか? 以下は、django-registration アプリの forms.py のコードです。
