如何创建用户配置文件更新视图/表单?

Question

我试图更新用户配置文件，但我不能得到我在这里做什么错误。

#forms.py
class AddStudentUserForm(forms.ModelForm):
class Meta:
model = User
fields = ["username", "first_name", "last_name"]
class AddStudentStaffForm(forms.ModelForm):
class Meta:
model = Staff
fields = ["gender", "dob", "mob", "img"]
#views.py
def editProfile(request, user, id):
if request.POST:
staffform = AddStudentStaffForm(request.POST or None, request.FILES or None, instance=request.user.staff_profile)
userform = AddStudentUserForm(data=request.POST, instance=request.user)
if staffform.is_valid():
staffform.save()
if userform.is_valid():
userform.save()
return redirect(profile,user)
return render(request, 'edit.html')
#models.py
class Staff(models.Model):
Male = 'Male'
Female = 'Female'
Other = 'Other'
GENDER_CHOICE = (
(Male, 'Male'),
(Female, 'Female'),
(Other, 'Other')
)
id = models.AutoField(primary_key=True)
admin = models.OneToOneField(User, related_name='staff_profile', on_delete=models.CASCADE)
gender = models.CharField(max_length=10, choices=GENDER_CHOICE, default=Male)
dob = models.DateField(auto_now_add=False, blank=True, null=True, default=None)
mob = models.IntegerField(blank=True, null=True, default=None)
img = models.ImageField(upload_to='staff/', blank="True", null="True")
objects = models.Manager()
@receiver(post_save, sender=User)
def create_user_profile(sender, instance, created, **kwargs):
if created:
Staff.objects.create(user=instance)
@receiver(post_save, sender=User)
def save_user_profile(sender, instance, **kwargs):
instance.staff_profile.save()
def __str__(self):
return self.gender

我开始创建一个学生管理系统项目。但是我在开发它的过程中遇到了一些困难。我试了很多方法来解决这些问题，但由于我无法解决。

这里，如果我想更新Staff模型字段，如性别，dob, mob，它将成功更新，但当我试图更新用户模型字段，如username, first_name, last_name时，它将不更新。我认为if userform.is_valid():条件不能运行，但是我不明白我在这里犯了什么错误。

你可以调试为什么表单是无效的，试试下面的代码:

if userform.is_valid():
userform.save()
return redirect(profile,user)
else:
print userform.errors #To see the form errors in the console.
