面对django形式的问题

Question

我在django表格中面临一些问题。问题是即使我把这段代码＆＃34; attrs = {＆＃39; class＆＃39;：＆＃39; form-control＆＃39;}＆＃34;但是当进入site和inspect-element时，html并没有包含这个类

它显示了这个......

anything

因为你可以看到它没有呈现出来＆＃39;：＆＃39; form-control＆＃39;

我可能做错了，请告诉我如何解决这个问题???

forms.py，view.py和.html文件代码如下所示

forms.py

anything.

contact.html

<input id="id_name" maxlength="100" name="name" type="text" required="">

views.py

from django import forms
from .models import ContactUs


class ContactUsForm(forms.ModelForm):
    name = forms.CharField(required=True, widget=forms.TextInput(attrs={'class': 'form-control'})),
    email = forms.EmailField(required=True),
    subject = forms.CharField(required=True),
    message = forms.CharField(
        required=True,
        widget=forms.Textarea(attrs={'class': 'form-control'})
    ),
    class Meta:
        model = ContactUs
        fields = ['name', 'email', 'subject', 'message']

只需更新您的forms.py类，如下所示，它将添加表单字段属性。

forms.py

class ContactUsForm(forms.ModelForm):
    def __init__(self, *args, **kwargs):
        super(ContactUsForm, self).__init__(*args, **kwargs)
        self.fields['description'].widget = forms.TextInput(attrs={'class': 'form-control'})
        self.fields['message'].widget = forms.Textarea(attrs={'class': 'form-control'})

    name = forms.CharField(required=True)
    email = forms.EmailField(required=True)
    subject = forms.CharField(required=True)
    message = forms.CharField(required=True)
    class Meta:
        model = ContactUs
        fields = ['name', 'email', 'subject', 'message']
