-------------------------------------+-------------------------------------
Currently, when using `dumpdata` to export application data, users often
need to manually exclude Django-managed models such as content types,
permissions, admin logs, and sessions.

For example:

{{{
python manage.py dumpdata \
--exclude contenttypes \
--exclude auth.Permission \
--exclude admin.LogEntry \
--exclude sessions.Session
}}}

This is repetitive and easy to get wrong, especially across projects with
different INSTALLED_APPS.

Some of this data is environment-specific or regenerated by Django through
migrations and post-migrate handlers. Including it in fixtures can cause
conflicts or unwanted records when loading data into another database.

I would like to propose adding a convenience option to dumpdata, for
example:


{{{
python manage.py dumpdata --exclude-system
}}}

or possibly:


{{{
python manage.py dumpdata --exclude-internal

}}}

This option would exclude a predefined set of Django-managed/internal
models from serialization.

Possible candidates could include:



{{{
- contenttypes.ContentType
- auth.Permission
- admin.LogEntry
- sessions.Session
}}}


The exact list and option name can be discussed.

This would be backwards-compatible because the behavior would only apply
when the option is explicitly provided. Existing dumpdata behavior would
remain unchanged.

Comment:

Thanks for raising the issue, however, I think that since the list of
excluded models is likely to vary from project to project, I would
recommend to simply create a custom management command that meets your
requirements. With AI, such a command can be created trivially and you
won't be bound to Django's slow release cycle.
