我是Django的新手，我收到了标题中写的错误。我谷歌它，但我找不到任何东西。实际上我想做的只是添加“评论”到我的博客网站。我添加我的代码如下。谢谢你 我的档案：

答案 0 :(得分：12)
您需要删除'body '字段末尾的空格，您应该'body'，如下所示：
class CommentForm(forms.ModelForm):
class Meta:
model = Comment
fields = ('name', 'email', 'body')
答案 1 :(得分：4)
如果表单的字段中包含editable=False的模型字段，也会出现相同的错误。删除模型字段上的editable属性可修复错误。
答案 2 :(得分：0)
删除“ body”中的空格 它看起来像这样
class CommentForm(forms.ModelForm):
class Meta:
model = Comment
fields = ('name', 'email', 'body')
答案 3 :(得分：0)
我浪费了很多时间，因为我不小心在模型的字段定义后面加上了一个逗号
答案 4 :(得分：0)
我刚刚遇到了这个问题的一个变体，其中表单中字段名称的拼写与模型中的拼写相同。我仍然收到错误。
我像这样声明了模型字段：
body = BooleanField(name="The comment's body text")
错误是在我想说name的地方说了verbose_name。
因此，模型中确实没有名为 body 的字段，就像错误消息声称的那样，而现在该字段被称为更长的时间。
