Problem¶

pulpcore defines functional tests to verify filtering publications by repository_version, distributions, and pulp_created (see
https://github.com/pulp/pulpcore/blob/master/pulpcore/tests/functional/api/using_plugin/test_crd_publications.py#L93-L132).

Funnily enough, PublicationViewset defines no filters, but the tests pass. That's because DRF simply ignores the filter parameters in this case and returns all publications. Since there is a single publication overall in these tests, this result isn't any different from the result a proper filter implementation would return.

Solution¶

1. Decide which filters to actually implement (proposal: at least repository_version (NB it has already been noted in #5665 that this does not work))
2. Implement these filters
3. Include negative test cases
