为什么不保存此表格？

Question

下面的代码现在是一个简单的帐户注册，当我提交此表单时，它会将我重定向到主页，这意味着我的表单有效并且可以运行，但是当我查看“管理”页面时，我看到该帐户尚未注册，我没有错。因此，我在这里可以了解到我的代码已经可以运行了，但是尚未保存。那么，如何通过FormView保存成员？在此先感谢

因为FormView不是save()表格。它可以用于任何形式，而不仅限于ModelForm。并非每个Form都有save()方法。

FormView在form_valid()中的唯一操作是重定向到成功URL。您必须告诉自己在验证表单有效之后要做什么：

def form_valid(self, form):
    form.save()
    return super().form_valid(form)

您可以看到FormView here的内部工作原理。

您可以使用CreateView代替FormView。这样可以为您节省开支。
