如何在Django的扩展用户创建表单中保存自定义添加的字段

Question

I am pretty new to Django and i made a custom signup form by extending the UserCreationForms in Django.

class SignUpForm(UserCreationForm): #This class will be used in views of account to make sigupform
user_type = forms.CharField(required=True,widget=forms.Select(choices=usertypes))
email = forms.CharField(max_length=254, required=True, widget=forms.EmailInput())
class Meta:
    model = User
    fields = ['username', 'user_type','email','password1','password2']
def save(self,commit=True):
    user = super(SignUpForm, self).save(commit=False)
    user.user_type = self.cleaned_data['user_type']
    print('Flag3')
    if commit:
        user.save()
    return user

It is working fine with the view :

def signup(request):
if request.method == 'POST':
    form = SignUpForm(request.POST)
    print('Flag0')
    if form.is_valid():
        user = form.save()
        if user.user_type == 'Seller' or user.user_type=='seller':
            print('Flag1')
            auth_login(request, user)
            print('Flag2')
            print(user.user_type)
            group = Group.objects.get(name='Seller')
            print(group.name)
            print('Flag3')
            user.groups.add(group)
            return redirect('get_seller')
        if user.user_type == 'Customer' or user.user_type=='customer':
            print('Flag1')
            auth_login(request, user)
            print('Flag2')
            print(user.user_type)
            group = Group.objects.get(name='Customer')
            print(group.name)
            print('Flag3')
            user.groups.add(group)
            return redirect('home')
else:
    form = SignUpForm()
return render(request, 'signup.html', {'form': form})

I added flags because is was checking the progress of the form.

The problem that i am facing is that i want to save the custom field that made user_type .

I don't know how to save the custom field or if it is being saved how to get the value.

Update:I printed the user.user_type . By : def save(self,commit=True): user = super(SignUpForm, self).save(commit=False) user.user_type = self.cleaned_data['user_type'] print(user.user_type)

Django's User Model does not have user_type field. If you want user_type field to be part of Django's User Model. Then use AbstractUser model and create a custom user model.

from django.contrib.auth.models import AbstractUser

class CustomUser(AbstractUser):
    user_type = models.CharField(max_lenght=20, choices=usertypes)

Now use this custom model, while create a your form.
