It looks `makemigrations` is unable to generate migrations for a model
that contains `CharField` with `blank=False` or with default value (which
is `blank=False`).
I did manage to replicate it on Django 1.9, 1.10, 1.10.8, 1.11, 1.11.4,
1.11.5.
The issue can be reproduced using the following steps:
1. Create an app with `models.py` like this one:
{{{
from django.db import models
class ExternalResourcePage(models.Model):
# authors = models.CharField(max_length=256)
publication_date = models.DateField()
show_on_website = models.BooleanField(default=True)
}}}
2. Run the `makemigrations` command. It will generate an initial migration
file.
3. Uncomment the `authors` field.
4. Run the `makemigrations` command again. It will not generate a new
migration file and will not give you any output. Exit code is `0`.
`makemigrations` works fine with `authors =
models.CharField(max_length=256, blank=True)`
Expected result: `makemigrations` creates a migration file or fails with a
traceback in case of any exceptions.
