I cann't creat new table in sqlite3 from django - django-models

Question

When I added new string in models.py his tables did't create in sqlite3. What I do wrong, again :)
python manage.py makemigrations
python manage.py migrate - I did!
It's happend, when I don't input templates information after messege:
Please enter the default value now as valid Python.
The datetime and django.utils.timezone module are available so you can do e.g. timezone.now.
I imputed just 1 and enter. After thet it broke.
If you need different information give me know, please.

WARNINGS:
meetups.Meetup.participant: (fields.W340) null has no effect on ManyToManyField.
You are trying to add a non-nullable field 'dates' to meetup without a default; we can't do that (the database needs something to populate existing rows).
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 let me add a default in models.py
Select an option: 1
Please enter the default value now, as valid Python
