Python 位于/ads/ad/2/comment的值错误

我试图添加评论到一个用户发布的广告。当我按下“注释”按钮时，它显示的是注释。 这是我的型号。py

这是我的视图。py

最后是我的模板ad_detail.html

您应该在此处使用

ModelForm

而不是

Form

class CommentForm(forms.ModelForm):
    comment = forms.CharField(required=True, max_length=500, min_length=3, strip=True)

    class Meta:
        model = Comment
        fields = ['text']
在您的
CommentCreateView
中，您的所有者收到了
请求
，这就是您显示该错误的原因。因此：

comment = Comment(text=request.POST['comment'], owner=request.user, ad=ad)

您的imgur图像未显示。@BiploveLamichhane我已更新图像链接。谢谢你的回复。
