Re: handling IntegrityError: Duplicate entry in UserCreationForm

Hi Sachin,

If you have added the unique=True later and migrated the existing table, I would also suggest you to first clean up  the NULL and duplicate entries using a script or even from shell.

After doing that you can use 

  try: 

     # your code here

  except IntegrityError: 

     #create variables here to send user error message

One more pointer - try checking for the user input( X.object.filter method) in the unique fields in database before performing .save

hi Sachin,

Please use django's form clean method in order to validate your phone_num field.

You can also override the django's clean method by using your own clean_phone_field method.
Please refer the link:-

https://docs.djangoproject.com/en/dev/ref/forms/validation/

I am sure that a small googling on overriding the clean method in django form class will defiantly help you.

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 ??
