I found bug in migrations.
I had Model2 with FK to other Model1 and unique_key (model1, ...)
Then I changed Model2 - removed FK to Model1, created FK to Model3 and
changed unique_key on (model3, ...)
It resulted as follows:
{{{
migrations.RemoveField(
model_name='model1',
name='model1',
),
migrations.AlterUniqueTogether(
name='model1',
unique_together=set([('model3', 'day', 'comment')]),
),
}}}
Applying migrations raised django.core.exceptions.FieldDoesNotExist
It was corrected when I interchanged operations
{{{
migrations.AlterUniqueTogether(
name='model1',
unique_together=set([('model3', 'day', 'comment')]),
),
migrations.RemoveField(
model_name='model1',
name='model1',
),
}}}
