I'm having problems with a migration after cleaning up an oddity with a
date field and I'm not sure how to fix it. Any advice appreciated.
I made this change to a date field:
- start_date = models.DateField(db_index=True, default=False,
- help_text="The date enrollment can begin
this Season.")
+ start_date = models.DateField(db_index=True, help_text="The date
enrollment can begin this Season.")
I'm not sure how a default of False ever made it, but I ran across it and
fixed it.
This is the migration that was created:
class Migration(migrations.Migration):
dependencies = [
('district', '0012_auto_20160622_1741'),
]
operations = [
migrations.AlterField(
model_name='season',
name='start_date',
field=models.DateField(help_text=b'The date enrollment can
begin this Season.', db_index=True),
),
]
This is the error I get trying to run the migration:
