Question

我想从django自定义UserCreationForm。我做了以下

class myUserCreationForm(UserCreationForm):


    class Meta:
        model=User
        fields = ('username', 'password1', 'password2')
        widgets = {
            'username':TextInput(attrs={'class':'form-control'}),
            'password':TextInput(attrs={'class':'form-control'}),
            'password2':TextInput(attrs={'class':'form-control'}),
}

但它不起作用。渲染模板时创建输入框没有附加表单控件类。可能有什么不对？

Answer 1

在遇到同样的问题时，我偶然发现了这一点。您可以在myUserCreationForm类上覆盖init方法来设置表单的属性。

class myUserCreationForm(UserCreationForm):

class Meta:
    model=User
    fields = ('username', 'password1', 'password2')

def __init__(self, *args, **kwargs):
    super(myUserCreationForm, self).__init__(*args, **kwargs)

    self.fields['username'].widget.attrs['class'] = 'form-control'
    self.fields['password1'].widget.attrs['class'] = 'form-control'
    self.fields['password2'].widget.attrs['class'] = 'form-control'

Answer 2

您需要从sctratch创建表单，它不应该扩展UserCreationForm。 UserCreationForm在其中明确定义了用户名字段以及其他一些字段。你可以看一下here。

Answer 3

您应该覆盖Meta类以上的字段。这对我有用：

class CustomCreateUserForm(UserCreationForm):

username = forms.RegexField(
    label=_("Login"), max_length=30, regex=r"^[\w.@+-]+$",
    help_text=_("Required. 30 characters or fewer. Letters, digits and "
                "@/./+/-/_ only."),
    error_messages={
        'invalid': _("This value may contain only letters, numbers and "
                     "@/./+/-/_ characters.")},
    widget=TextInput(attrs={'class': 'form-control',
                            'required': 'true',
                            'placeholder': 'Login'
    })
)

password1 = forms.CharField(
    label=_("Password"),
    widget=forms.PasswordInput(attrs={'class': 'form-control',
                                      'required': 'true',

    })
)
password2 = forms.CharField(
    label=_("Password confirmation"),
    widget=forms.PasswordInput(attrs={'class': 'form-control',
                                      'type': 'password',
                                      'required': 'true',
    }),
    help_text=_("Enter the same password as above, for verification.")
)

first_name = forms.CharField(
    label=_("Name"),
    widget=forms.TextInput(attrs={'class': 'form-control',
                                  'type': 'text',
                                  'required': 'true',
    }),
    help_text=_("Enter user first and last name.")
)

email = forms.CharField(
    label=_("Email"),
    widget=forms.TextInput(attrs={'class': 'form-control',
                                  'type': 'email',
                                  'placeholder': 'Email address',
                                  'required': 'true'
    })
)

class Meta:
        model = User

Answer 4

class myUserCreationForm(UserCreationForm):

    password1 = forms.CharField(
        label='Password',
        widget=forms.PasswordInput(attrs={'class': 'form-control'})
    )
    password2 = forms.CharField(
        label='Password',
        widget=forms.PasswordInput(attrs={'class': 'form-control'})
    )

    class Meta:
        model = User
        fields = ('username', 'password1', 'password2')
        widgets = {
            'username': TextInput(attrs={'class': 'form-control'}),
            # 'password': TextInput(attrs={'class': 'form-control'}),   # Remove This Line
            # 'password2': TextInput(attrs={'class': 'form-control'}),  # Remove This Line
        }
