python3 dumpdata 'ers_database.c3rs' > test_mapper.json
CommandError: Unknown model: ers_database.c3rs

also, ers_database has its own

Database router in use, both utilize the router and use the same app_label. Migrations work.

'python3 dumpdata ers_database' produces a zero-length file though there is data in the database.

Database type is postgresql

I'm not sure this is a supported configuration of models. Can you provide a sample app for better clarity?

Please see #25127 for a documentation request about how to define models in multiple modules which may be relevant.

I'll attempt to put together a representative case.

Thanks for the reference link.

I was able to reproduce the issue in sample I ginned up, which mimics the same db architecture and module/submodule layout as the system I encountered the problem on. However, in the process of working with my sample, I came to realize that the dumpdata command works with the app_labels of the models and that using dumpdata app_label.ModelClassName

(where the model is in the of the submodule) works just fine and that I was doing it wrong on the original system.

When I ran into difficulties I was trying to do a dumpdata app_label.subapp_label

which dumpdata reasonably considered to be a class
and dumpdata app_label.subapp_label.ModelClassName'

which it considered to be an app

Please close as not a bug.
