Re: How to generate a unique 9 digit random id for every registered user?

Note that above solution doesn't guarantee unique id. As it is a problem of any pseudorandom generator.

So it is possible (but unlikely) that insertion fails.

class MyModel(models.Model):
    code = models.CharField(
        max_length=9, default=generate_random_code, db_index=True
    )

Hi, please try the code above.

Hello,

My model consists of user details such as username and his id which is auto-generated by DB(indexing). 

Apart from this, I need to assign a random unique 9 digit number for every user.

The reason for assigning a random number to a registered user is to search a particular user using his permanent random id which we have generated.

Solutions with the model description will be very helpful.

Thank you!
