steps to reproduce: 1. Compare https://addons.mozilla.org/en-US/firefox/addon/little-flowers/ vs. https://addons-dev.allizom.org/en-US/firefox/addon/little-flowers/ 2. Notice the theme owner name in both links observed behavior: In prod, theme owner name is a link which loads the user profile page. On -dev it is not a link. Please investigate

I think this is just a matter of enabling the `personas-migration-completed` waffle switch in prod. I don't think the owner of Little Flowers was ever migrated on -dev but was on prod. Clouser, did we fully migrate all the users on -dev?

I don't think so, and either way it's test data - no telling what is going on. I don't think this is valid unless we do a fresh dump from prod.

None of the themes on dev have the owner names enabled. This cannot be an issue related to specific test data.

The Takeaway: There's no bug to speak of, and all the user links will magically appear everywhere on theme pages when we push to production. The Excuse: We ran the user migration script on prod. The user exists on prod at (https://addons.mozilla.org/en-US/firefox/user/bluszcz/) but does not exist on -dev (https://addons-dev.allizom.org/en-US/firefox/user/bluszcz/). Notice how the "by bluszcz" is not a link but "Artist: bluszcz" is a link: http://f.cl.ly/items/1S2V1i0H34030E0W0y1x/Screen%20Shot%202013-04-04%20at%2012.10.43%20AM.png https://github.com/mozilla/zamboni/blob/master/apps/addons/models.py#L1744 Once we push to production and `personas-migration-completed` is enabled, you'll see author links everywhere for themes. This was an oversight on our part, but both of them should be links only when the `personas-migration-completed` switch is enabled. Because the user does not exist on -dev that's why you see both a blank byline and text instead of a link for the artist name, respectively: http://f.cl.ly/items/3y3d3n1J2B0c3F210q38/Screen%20Shot%202013-04-04%20at%2012.12.27%20AM.png My sincere apologies for overcomplicating this, and I hope my explanation actually isn't any more confusing than the bug in question here.
