Re: handling IntegrityError: Duplicate entry in UserCreationForm

hey guys, got the solution:

for each field to validate, I wrote a validate function:

code snippet:

def clean_<field>:
    try:
        UserProfile.objects.get(phone_num=self.cleaned_data['<field>'])
    except UserProfile.DoesNotExist:
        return self.cleaned_data["<field>"]
    raise forms.ValidationError(("FIELD VALUE already exist"))

@ Kelly: thank you very much for pointing me to django's source code.

Yes I got that validation done and applied the same code for validation. Below is the snippet :

   profile.serial_num = self.cleaned_data['phone_num']
        try:
            profile._default_manager.get(phone_num=profile.serial_num)
        except UserProfile.DoesNotExist:
            profile.serial_num = profile.phone_num
    raise forms.ValidationError("Phone number already exist")

@ all

Now the next problem is, similar snippet appears in

/site-packages/django/contrib/auth/forms.py

throws an error in the template form itself, but my code only shows up error in django's traceback, how can I bring it to front ?

so that as soon as one fills phone number field it and press submit, it should say 'Phone number already exist'.

m I doing wrong in using UserCreationForm ? or UserProfile. I m using user.get_profile() for profile fields.

If you ever want to know how the UserCreationForm works, the source is always available not only on your machine but also on

Hello,

I m extending my auth user model to add addition entries like phone numbers and emp_id. In the model I m marking both the fields as unique=True.
Form generation is using UserCreationForm. But whenever I try to save same phone number or emp_id it throws

IntegrityError: (1062, "Duplicate entry '447' for key 'phone_num'")

How to handle this error and show it to user during form input?

Also how do the same UserCreationForm validates duplicate entry for username etc ??
