     45You are trying to add a non-nullable field 'id' to browsertest without a default; we can't do that (the database needs something to populate existing rows).
     46Please select a fix:
     47 1) Provide a one-off default now (will be set on all existing rows with a null value for this column)
     48 2) Quit, and let me add a default in models.py
     49Select an option: 1
     50Please enter the default value now, as valid Python
     51The datetime and django.utils.timezone modules are available, so you can do e.g. timezone.now
     52Type 'exit' to exit this prompt
     53>>> 1
