Re: It is impossible to add a non-nullable field 'details1' to feature without specifying a default. This is because the database needs something to populate existing rows.

Enter 1 then ' ' rather. Sorry 😓

You are seen that error probably because you modified your models after adding some items to database already. When prompted with the error, enter 2, then ' ' an empty string.

Am new in django and have been getting errors in migrations, i need help
when i try to do migrations it keeps telling me this

Please select a fix:
 1) Provide a one-off default now (will be set on all existing rows with a null value for this column)
 2) Quit and manually define a default value in models.py.
Thank you  in advance
from django.db import models

# Create your models here.


class feature(models.Model) :
   
    name = models.CharField(max_length=100)
    extra = models.CharField(max_length=100)
    details1 = models.CharField(max_length=500)
   
class art(models.Model):
   
    name = models.CharField(max_length=100)
    details = models.CharField(max_length=500)
