如何從Django中的UserCreationForm中刪除用戶名字段

Question

我希望我的用戶注冊頁面顯示電子郵件和密碼字段，而不是用戶名。 我創建了這個注冊表：

class RegisterForm(UserCreationForm):
    email = forms.EmailField(label = "Email")
    #fullname = forms.CharField(label = "First name")

    class Meta:
        model = User
        fields = ("email", )

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

但用戶名仍然顯示。 我需要覆蓋其他內容嗎？

Answer 1

您可以從表單的字段中彈出用戶名，如下所示：

class RegisterForm(UserCreationForm):

    def __init__(self, *args, **kwargs): 
        super(RegisterForm, self).__init__(*args, **kwargs) 
        # remove username
        self.fields.pop('username')
    ...

但是之后你需要在保存之前填寫一些隨機用戶名：

from random import choice
from string import letters
...

class RegisterForm(UserCreationForm):
...
    def save(self):
        random = ''.join([choice(letters) for i in xrange(30)])
        self.instance.username = random
        return super(RegisterForm, self).save()

當您以這種方式破解它時還需要考慮其他因素，例如確保您的LoginForm稍后在需要時提取用戶名：

class LoginForm(AuthenticationForm):

    email = forms.EmailField(label=_("E-mail"), max_length=75)

    def __init__(self, *args, **kwargs): 
        super(LoginForm, self).__init__(*args, **kwargs) 
        self.fields['email'].required = True 
        # remove username
        self.fields.pop('username')

    def clean(self):
        user = User.objects.get(email=self.cleaned_data.get('email'))
        self.cleaned_data['username'] = user.username
        return super(LoginForm, self).clean()

將該字段添加到Meta類的排除：

class RegisterForm(UserCreationForm):
    email = forms.EmailField(label = "Email")
    #fullname = forms.CharField(label = "First name")

    class Meta:
        model = User
        exclude = ['username',]
