Question

我正在尝试在表单中使用taggit，但我收到了这条消息：

'unicode' object has no attribute 'set'

表示save_m2m方法。这是我的代码。

if form.is_valid():
            response = form.save(commit=False)
            #response = super(ReviewForm, self).save(commit=False)
            response.user = user
            response.tag = form.cleaned_data['tag']
            response.product = product
            response.review_text = form.cleaned_data['review_text']
            response.created = time.strftime("%c")
            response.updated = time.strftime("%c")
            response.save()
            form.save_m2m()

我正在关注taggit docs：

Answer 1

我对django-taggit不太熟悉，但在ReviewForm中尝试更改

tag = forms.CharField( ...

类似

tags = TagField()

或使用

  'tags': TagWidget()

请参阅django - django-taggit form和Django-Taggit in Edit Form

save_m2m'unicode'对象没有属性'set'
