python - How to disable migrations for specific Django 1.7 apps? -

how disable migrations specific apps in django>=1.7?

i'm trying upgrade django 1.6 1.7, , made trivial changes django's auth app change labels, design flaw in django>=1.7 treats attributes part of database schema, triggering new migration. moreover, running manage.py makemigration myapp generates migration other apps touching myapp, though i'm not explicitly trying create migration auth, it's forcing me so, , see no way turn off.

this creating havoc, since have dozen apps touch auth, causing django create on dozen pointless migrations.

i tried creating custom auth migration directory using migration_modules, doesn't seem work. app relies on auth throws error like:

valueerror: lookup failed model referenced field helpdesk.queue.group: auth.group 

if try migrate auth. how fix this? ideally, simplest solution "turn off" migrations auth, since i'm not making changes it.

edit: custom migration django forces me generate:

class migration(migrations.migration):      dependencies = [         ('admin', '0001_initial'),         ('auth', '0001_initial'),     ]      operations = [         migrations.createmodel(             name='logentry',             fields=[             ],             options={                 'ordering': ('-action_time',),                 'verbose_name': 'log entry',                 'proxy': true,                 'verbose_name_plural': 'log entries',             },             bases=('admin.logentry',),         ),         migrations.alterfield(             model_name='permission',             name='name',             field=models.charfield(max_length=500, verbose_name='name'),             preserve_default=true,         ),         migrations.alterfield(             model_name='user',             name='username',             field=models.charfield(help_text='required. 30 characters or fewer. letters, digits , @/./+/-/_ only.', unique=true, max_length=75, verbose_name='username', validators=[django.core.validators.regexvalidator('^[\\w.@+-]+$', 'enter valid username.', 'invalid')]),             preserve_default=true,         ),     ] 

my custom changes make username , email fields same length (because 2 same in system), change default validator validate them both email address. i've been using these changes since django 1.3. presumably, they're problem i'm no longer using south , have re-generate migrations.

and looks can't use migration_modules generate custom migration folder, because have other apps depend on auth's 0001_initial migration, like:

class migration(migrations.migration):      dependencies = [         migrations.swappable_dependency(settings.auth_user_model),     ] 

so if override migration_modules like:

migration_modules = {     'auth': 'myoverrides.auth_migrations', } 

that migration disappears, throwing error.

it's bit of hack, modified settings.py check sys.argv "makemigrations" , remove conflicting apps, unmanaged, installed_apps list. allowed me generate custom auth migration. e.g.

if 'makemigrations' in sys.argv     installed_apps.remove('conflicting_third_party_app')
