Django：表单未保存到数据库

Question

我在这里看到过类似类型的问题，但我仍然无法解决我的问题。当我在视图中保存 PhotographerProfileForm 时，表单会正确呈现，但在单击更新/提交后实际上并没有保存任何内容。

也没有显示错误。

我现在拥有的是预先填充的字段，我希望能够将这些字段保存在数据库中，但没有任何反应，目前您只能从管理面板更新它。

    location = models.CharField(max_length=200)
    bio = models.TextField(max_length=500)

    def __str__(self):
        return self.user.username

User.profile = property(lambda u: PhotographerProfile.objects.get_or_create(user=u)[0])

在处理表单之前，您在视图的第三行返回。删除该行。
