Django没有属性＆＃39; HiddenInput＆＃39;

Question

我在以下代码中收到错误module 'django.forms.forms' has no attribute 'HiddenInput'：

from django.forms import ModelForm, forms

from comments.models import Comment


class CommentForm(ModelForm):
    class Meta:
        model = Comment
        fields = ['video', 'text']
        widgets = {'video': forms.HiddenInput(),
                   'text': forms.TextArea()}

有谁知道造成这种情况的原因是什么？我在文档中查了一下，HiddenInput（）应该有效（https://docs.djangoproject.com/en/2.0/ref/forms/widgets/）。

Answer 1

您导入错误，请将导入更改为：

from django import forms

并更新表单的基类：

class CommentForm(forms.ModelForm):
    class Meta:
        model = Comment
        fields = ['video', 'text']
        widgets = {'video': forms.HiddenInput(),
                   'text': forms.Textarea()}

Answer 2

继承forms.ModelForm

class CommentForm(forms.ModelForm):
    class Meta:
        model = Comment
        fields = ('video', 'text')
        widgets = {'video': forms.HiddenInput(),
                    'text': forms.Textarea() }
