----------------------------+----------------------------
I'm having a problem with migrations. They are being created by
makemigrations even after no change has been made. I'm in my 57th
migration so I can't create a simple way to reproduce the problem.
My model is this:
{{{#!python
class Layer3d(Process):
last_modified = models.DateTimeField(auto_now=True)
info = models.TextField(verbose_name=_('layer info'),
default='{}')
class Layer3dProjection(models.Model, Layer3dProjectionMixin):
name = models.CharField(verbose_name=_('name'), max_length=40,
default='', validators=[name_regex], unique=True)
llist = models.ForeignKey(LayerList, verbose_name=_('layer list'))
layer3d = models.ForeignKey(Layer3d)
distance = models.FloatField(default=-1)
last_modified = models.DateTimeField(auto_now=True)
class Meta:
unique_together = (('llist', 'name'),)
ordering = ['name']
}}}
This migration is being created, time after time, without modifying any
model.
{{{#!python
# -*- coding: utf-8 -*-
# Generated by Django 1.9.7 on 2016-08-09 00:50
from __future__ import unicode_literals
from django.db import migrations, models
import django.db.models.deletion
The migration being created is this.
class Migration(migrations.Migration):
dependencies = [
('studies', '0057_auto_20160809_0047'),
]
operations = [
migrations.AlterField(
model_name='layer3dprojection',
name='layer3d',
field=models.ForeignKey(on_delete=django.db.models.deletion.CASCADE,
to='studies.Layer3d'),
),
]
}}}
