dumpdata and "managed" flag on models

[ijstokes]

Should "dumpdata" process models which are flagged with "managed = False"? My sense is no it shouldn't, and if so the attached patch (against latest SVN) will correct this.

It looks like there is some "exclude" mechanism which can be used to skip certain models, but I don't see how to invoke that from the command line. Perhaps it is an undocumented feature.

Patch to add checking of model._meta.managed to decide whether model should be dumped

This is a duplicate of #13816.

The documentation for managed (​http://docs.djangoproject.com/en/1.3/ref/models/options/#managed) explicitly states its only effect is on creation/deletion of tables; I don't understand where the idea that dumpdata would pay some special attention to managed=False models and ignore those comes from?

--exclude is also documented for dumpdata: ​http://docs.djangoproject.com/en/1.3/ref/django-admin/#dumpdata-appname-appname-appname-model, though the formatting where some options have headers and others do not perhaps is obscuring its existence (and that may be worthy of a ticket). In any case, it is a documented command line flag. Description of what it supports, exactly, is both in the doc and in the manage.py help dumpdata output, so I don't understand where the idea it is some undocumented internal feature came from either.
