Description (last modified by Tim Graham)

I removed the null=True as suggested in django 1.8 warnings from my M2M field in the model.

django migrations created the following:

class Migration(migrations.Migration):

[...]
    operations = [
        migrations.AlterField(model_name='project', name='my_field', field=models.ManyToManyField(related_name='in_charge_projects', verbose_name='label', to='account.Employee', blank=True),
        ),
[...]
]

I get the following error:

"django.core.exceptions.FieldDoesNotExist: Project_my_field has no field named None"

Can not reproduce this locally.
Please provide a test project, where this error will exists.
