= Bug 509252 =
After landing the fix for bug 340662 (https://code.edge.launchpad.net/~adiroiban/launchpad/bug-340662-take-2/+merge/17598) the POTemplateSubsetNavigation will render the AdminPOTemplateSubset useless.

We should clean the security.py.

AdminPOTemplateSubset was added to fix bug 497438

== Proposed fix ==

Remove unused classed from security.py and refactor 

== Pre-implementation notes ==

Talking with Henning we decide not to include security checking code in the model. This is why the logic of showing translations of a series was spitted between the model and the view and the security checks were done in multiple places.

This restriction lead to a strange implementation where the check was done both in the view and the model and it was a source of confusion.

I merged this logic in a browser helper function and now the security check is only done once.

== Implementation details ==

These changes renders the AdminDistroSeriesLanguage class from security.py useless, so I have also removed it.

== Tests ==
lp-test -t distroseries-translations -t distroseries-views

== Demo and Q/A ==
Make sure you are a member of Ubuntu Translation Coordinators team (ubuntu-l10n-coordinator).
https://launchpad.dev/~ubuntu-l10n-coordinator

Go to the translation page for a distribution and hide translations for this series
ie: https://translations.launchpad.dev/ubuntu/hoary/+admin

Next go to the distribution series +template page
https://translations.launchpad.dev/ubuntu/hoary/+templates

You should see the Administer page for Evolution templates, including disabled-template .

As a member of Ubuntu Translation Coordinators team you should be able to administer them, just like for a normal series.

Login as a normal user you should see a page informing that the translations are currently closed
