自定义Django表单脆皮

问题描述

我有一张注册表，我在用脆皮。我想让输入字段看起来更好，所以我想向每个输入字段添加一个类，但是站点仅使用该类呈现第一个输入字段。 （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>

解决方法

from django import forms
from django.contrib.auth.models import User
from django.contrib.auth.forms import UserCreationForm
from crispy_forms.helper import FormHelper
from crispy_forms.layout import Layout,Submit,Row,Column



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

    class Meta:
        model = User
        fields = ['username','email','password1','password2']
        
    
    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',Column('password1',Column('password2',css_class='form-row'
            )
        )
