I was just looking into this issue today, as the version of Tastypie provided in Ubuntu Xenial 16.04 (0.12.0) does not work with the version of Django supplied (v1.8).
The 'commit_on_success' bug has now been fixed in Tastypie so the package source version should ideally be updated to at least v0.12.2 (See http://django-tastypie.readthedocs.io/en/latest/release_notes/v0.12.2.html). This also drops Python 2.6 support, so there is the option of dropping the python2 package or leaving it orphaned at the current release.
