Djangoユーザー登録フォームKeyError

Question

空のRegisterFormをリクエストすると、私はKeyErrorを取得します。サイトのリンクをクリックすると、GETリクエストが登録メソッドに送信され、form1 = RegisterForm（）行が起動すると思います。私はRegisterFormクラスに何か問題があると信じていますが、それが何であるか把握することはできません。 UserモデルとUserCreationFormを使用しています。どんな助けでも大歓迎です。

KeyError例外で/プロファイル/午後/ u'usernameを登録

Answer 1

のコメントが正しいと非常に有用でした！私は、「ユーザー名」にRegisterFormの「電子メール」フィールドの名前を変更するために必要な：

class RegisterForm(UserCreationForm): 
username = forms.EmailField(label = "Email") 
first_name = forms.CharField(label = "First name") 
last_name = forms.CharField(label = "Last name") 

class Meta: 
    model = User 
    fields = ("username", "first_name", "last_name") 

def clean_email(self): 
    username = self.cleaned_data['email'] 
    if User.objects.filter(email=email).exists(): 
     raise forms.ValidationError('Email already in use.') 
    return username 

def save(self, commit=True): 
    user = super(RegisterForm, self).save(commit=False) 
    user.username = self.cleaned_data["email"] 
    if commit: 
     user.save() 
    return user 

Answer 2

（あなたのケースusername中）USERNAME_FIELDは、フォームフィールドでない場合は、this issueどこUserCreationFormクラッシュに遭遇してきました。

この問題はDjango 1.10にのみ影響し、Djangoの以前のバージョンには影響しません。今後のDjango 1.10.1リリースで修正される予定です。
