I don't know if this is intended behavior, but having a simple model as:
{{{
class Foo(models.Model):
bar = models.SlugField()
}}}
Simple changes, that do have no impact on the database representation,
result in new migrations. For instance:
{{{
class Foo(models.Model):
bar = models.SlugField(editable=False)
}}}
results in:
{{{
# -*- coding: utf-8 -*-
from __future__ import unicode_literals
from django.db import models, migrations
class Migration(migrations.Migration):
dependencies = [
('testapp', '0001_initial'),
]
operations = [
migrations.AlterField(
model_name='foo',
name='bar',
field=models.SlugField(editable=False),
),
]
}}}
And further:
{{{
class Foo(models.Model):
bar = models.SlugField(
editable=False,
choices=[
('baz', 'Baz'),
('test', 'Test'),
]
)
}}}
Results in:
{{{
# -*- coding: utf-8 -*-
from __future__ import unicode_literals
from django.db import models, migrations
class Migration(migrations.Migration):
dependencies = [
('testapp', '0002_auto_20140614_2237'),
]
operations = [
migrations.AlterField(
model_name='foo',
name='bar',
field=models.SlugField(editable=False, choices=[('baz',
'Baz'), ('test', 'Test')]),
),
]
}}}
It is as if the detector does "too much" detecting. But again there might
well be a good reason for this. Just thought it would be a good thing to
address :)
