为什么这个表格不保存？

Question

下面的代码是一个简单的帐户注册现在，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使用，但是当我检查我的管理页面时，我看到该帐户是没有注册，我没有收到任何错误。因此我可以在这里了解到我的代码已经在工作但尚未保存。那么，如何通过FormView保存成员呢？提前致谢

Answer 1

因为 FormView 没有 save() 表格。它旨在用于任何形式，而不仅仅是 ModelForms。并非每个 Form 都有 save() 方法。

FormView 在 form_valid() 中做的唯一一件事就是重定向到成功 url。你必须自己告诉它在验证表单有效后你要做什么：

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 而不是 FormView。那将为您省钱。
