django - "Conflicting models in application..." with external database tables -

i have project number of applications accesses both local mysql database 100s of tables, , several external mysql , ms-sql server databases many more tables. of external tables defined in models using "managed=false" meta data.

i upgraded django 1.6 1.7 following instructions in release notes , other hints, etc. stackoveflow.

everything seems working again exception of of applications access remote database tables. here example message:

runtimeerror: conflicting 'bugview_deferred_description_disposition_divisioaf59cb28117de5eb6ddfea0476dab601' models in application 'nvbugsdw': <class 'bug_metrics.models_bugs.bugview_deferred_description_disposition_divisioaf59cb28117de5eb6ddfea0476dab601'> , <class 'bug_metrics.models_bugs.bugview_deferred_description_disposition_divisioaf59cb28117de5eb6ddfea0476dab601'>. 

the table bugview defined in file names models_bugs.py follows:

class bugview(models.model): bugid            = models.bigintegerfield(primary_key=true) module           = models.charfield(max_length=128, null=false) requester        = models.charfield(max_length=128, null=false) qaengineer       = models.charfield(max_length=128, null=false) engineer         = models.charfield(max_length=128, null=false) requestdate      = models.datetimefield(null=false) modifieddate     = models.datetimefield(null=false) priority         = models.charfield(max_length=50, null=false) severity         = models.charfield(max_length=50, null=false) disposition      = models.charfield(max_length=64, null=false) bugaction        = models.charfield(max_length=64, null=false) origin           = models.charfield(max_length=64, null=false) geographicorigin = models.charfield(max_length=128, null=false) division         = models.charfield(max_length=64, null=false) synopsis         = models.charfield(max_length=256, null=false) description      = models.charfield(max_length=1024, null=false) bugtype          = models.charfield(max_length=50, null=false) originalbugid    = models.bigintegerfield()  class meta:     app_label = 'nvbugsdw'     managed   = false     db_table  = 'bugview' 

in views.py file class imported like:

from .models_bugs import bugview 

i tried

from models_bugs import bugview bug_metrics.models_bugs import bugview 

"bug_metrics" application name.

i followed of suggestions posted on https://code.djangoproject.com/ticket/22280 no effect.

i'm @ loss @ point. suggestions?

also, may not related, in trying debug issue (by dumping sys.path in manage.py), noticed code in manage.py executed twice when run command

./manage.py runserver --nothreading 0.0.0.0:8081 

my sys.path is:

/opt/graphic_tools/gtools /usr/local/lib/python2.7/dist-packages/south-0.8.4-py2.7.egg /usr/lib/python2.7 /usr/lib/python2.7/plat-linux2 /usr/lib/python2.7/lib-tk /usr/lib/python2.7/lib-old /usr/lib/python2.7/lib-dynload /usr/local/lib/python2.7/dist-packages /usr/lib/python2.7/dist-packages /usr/lib/python2.7/dist-packages/pil /usr/lib/python2.7/dist-packages/gst-0.10 /usr/lib/python2.7/dist-packages/gtk-2.0 /usr/lib/pymodules/python2.7 /usr/lib/python2.7/dist-packages/ubuntu-sso-client /usr/lib/python2.7/dist-packages/ubuntuone-client /usr/lib/python2.7/dist-packages/ubuntuone-control-panel /usr/lib/python2.7/dist-packages/ubuntuone-couch /usr/lib/python2.7/dist-packages/ubuntuone-installer /usr/lib/python2.7/dist-packages/ubuntuone-storage-protocol 

"/opt/graphic_tools/gtools" project directory. not contain init.py file , contain of application sub-directories including "gtools" sub-directory.

one suggestion. did try synchronize 'remote' databases after upgrading new version of django? maybe not synced?

i assume have like: databases = {

'default': {some credentials},

'remote_db_name1': {some credentials},

'remote_db_name2': {some credentials}, ...

}

you can run

./manage.py migrate --database=remote_db_name1

./manage.py migrate --database=remote_db_name2

etc. (also, assume ran 'makemigrations' app before.)

the reason default migrate operates on 'default' db, others skipped.
