Django中的样式ModelForms不起作用

Question

我想在Django中使用UserCreationForm，但我需要在其中嵌入Bootstrap Classes，所以我决定覆盖它，不幸的是它不适用于样式化！

这是我的代码

forms.py

class UserCreationForm(forms.ModelForm):
"""
A form that creates a user, with no privileges, from the given username and
password.
"""
error_messages = {
    'password_mismatch': ("The two password fields didn't match."),
}
username = forms.CharField(label=("Password"),
    widget=forms.TextInput(attrs={'class': 'form-control input-lg', 'placeholder':'First Name',}))
password1 = forms.CharField(label=("Password"),
    widget=forms.PasswordInput(attrs={'class': 'form-control input-lg', 'placeholder':'First Name',}))
password2 = forms.CharField(label=("Password confirmation"),
    widget=forms.PasswordInput(attrs={'class': 'form-control input-lg', 'placeholder':'First Name',}),
    help_text=("Enter the same password as above, for verification."))

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

def clean_password2(self):
    password1 = self.cleaned_data.get("password1")
    password2 = self.cleaned_data.get("password2")
    if password1 and password2 and password1 != password2:
        raise forms.ValidationError(
            self.error_messages['password_mismatch'],
            code='password_mismatch',
        )
    return password2

def save(self, commit=True):
    user = super(UserCreationForm, self).save(commit=False)
    user.set_password(self.cleaned_data["password1"])
    if commit:
        user.save()
    return user

template.html

<div class="container makemargs"><div class="row"><h3 class="col-sm-offset-3 col-sm-6">Signup</h3></div><div class="row"><div class="col-sm-offset-1 col-sm-2"></div><div class="col-sm-6"><form id="signupForm" action="" method="POST" accept-charset="utf-8" class="form" role="form">{% csrf_token %}         {{form}}<button id="submitBtn" class="btn btn-block signup-btn" type="submit" disabled>Create my account</button></form></div></div></div></div>

感谢@hansTheFranz和他的answer 我刚刚使用了这个神奇的工具Widget Tweaks而且效果很好。

我必须使用append_attr而不是add_class。
