Question

我有一个名为UserInfo的模型。

class UserInfo(models.Model):
    username = models.CharField(max_length=240 , default = "" , blank = False , null = False)
    first_name = models.CharField(max_length=240 , default = "" , blank = False , null = False)
    last_name = models.CharField(max_length=240 , default="" , blank = False , null = False)
    address = models.CharField(max_length=500 , default="" , blank = False , null = False)
    email = models.CharField(max_length=240 , default="" , blank = False , null = False)
    phoneNumber = models.CharField(max_length=240 , default="" , blank = False , null = False)
    pincode = models.CharField(max_length=240 , default="" , blank = False , null = False)

我还有UserInfoForm这些字段。

class UserInfoForm(forms.ModelForm):
    class Meta:
        model = UserInfo
        fields = []
        for field in UserInfo._meta.get_fields(): #automatically update fields from userinfo model
            fields.append(field.name)
        exclude = ['username']

想要的是迭代在UserInfo模型的字段上，并使用UserInfoForm中的数据进行更新，而不是将其全部硬编码。

我试过这个：

obj = UserInfo.objects.get(email = request.user.email)
if obj.username == request.user.username: #basically a test to see if the same person is updating his profile, or is someone else using this email id
    for field in UserInfo._meta.get_fields():

        fieldname = field.name
        fieldvalue = form.cleaned_data.get(fieldname) 

        obj.field = fieldvalue #doesn't work
    obj.save()

但这不起作用。此代码完全没有显示错误，但数据库仍未更新。请建议一种方法，以便我可以为用户更新信息，迭代字段。

迭代模型字段并在Django中更新它们
