python - 如何解决属性错误'QueryDict'对象没有属性'company'？

问题描述

我想让一个用户可以创建另一个用户。我为此创建了一个表格。一开始它工作得很好，但后来我改变了一些东西，现在它不工作了，表单没有保存。我试图找出错误在哪里，但我找不到。我该如何解决？

注意：comp_name是一个隐藏字段，所以用户不应该看到它

/signup/ 'QueryDict' 对象的 AttributeError 没有属性 'company'

视图.py

    if request.method == 'POST':
        form = SignUpForm(request.POST)
        if form.is_valid():

            user = form.save()
            user.refresh_from_db()  # load the profile instance created by the signal
            user.is_active = False
            rank_form = RankForm(instance=user, user=request.user)
            rank_form.save()
            if form.cleaned_data['password1'] != "":
                user.set_password(form.cleaned_data['password1'])
