I have the following model:

```
class Site(models.Model):
    """
    Model for a site entry
    @author: Leonardo Pessoa
    @since: 05/09/2016 
    """
    from decimal import Decimal

    consolidated_financials     = models.BooleanField(blank=True)
    type                        = models.ForeignKey(Type)
    tier1_business              = models.ForeignKey(Business, limit_choices_to = {'tier': 1}, related_name='%(class)s_tier1')

```

Note that the `consolidated_financials` field has now the `blank=True` statement.
This was newly included. When I ran makemigrations, it didn't get the change, but when I add to `finance_manager_sso` it worked normally.

Is there a restriction with the Boolean field specifically?

Thanks
