自定义 Django 表单（脆皮）

Question

我有注册表，我用的是crispy。我想让输入字段看起来更好，所以我想为每个输入字段添加一个 class，但该站点只呈现带有 class 的第一个输入字段。（这是我的第一个 Django 项目，所以我对此很陌生）

这是我的 forms.py 文件：

from django import forms
from django.contrib.auth.models import User
from django.contrib.auth.forms import UserCreationForm



class UserRegisterForm(UserCreationForm):
email = forms.EmailField()

class Meta:
    model = User
    fields = ['username', 'email', 'password1', 'password2']
    widgets = {
        'username': forms.TextInput(attrs={'class': 'form-control input'}),

        'email': forms.EmailInput(attrs={'class': 'form-control input'}),

        'password1': forms.PasswordInput(attrs={'class': 'form-control input'}),

        'password2': forms.PasswordInput(attrs={'class': 'form-control input'}),

        

    }

这是模板：

<div class="sign-up">
   

<form class="form" method="POST">
    {% csrf_token %} 
    <fieldset class="form-group">
        <legend class="border-bottom mb-4, sign-up__header">Join Today</legend>
        {{ form|crispy }}
    </fieldset>
    <div class="form-group">
        <button class="btn btn-outline-info" type="submit">Sign up</button>
    </div>
</form>

</div>

    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.helper = FormHelper()
        self.helper.layout = Layout(
            Row(
                Column('username', css_class='form-group col-md-3 mb-0 input'),
                Column('email', css_class='form-group col-md-3 mb-0 input'),
                Column('password1', css_class='form-group col-md-3 mb-0 input'),
                Column('password2', css_class='form-group col-md-3 mb-0 input'),
                css_class='form-row'
            )
        )
