Description (last modified by )
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"
