Deploy fails with nasty PGError if no blurbs have been added

[cwoodcox]

I was setting up an install in a new app today, and I admittedly got the steps a little out of order, but it was a little weird to have to tail the logs on the copycopter server to figure it out...

Started POST "/api/v2/projects/[snip]/deploys" for 127.0.0.1 at 2012-11-12 18:34:10 +0000
Processing by Api::V2::DeploysController#create as */*
  Parameters: {"project_id"=>"[snip]"}
Completed 500 Internal Server Error in 5ms

ActiveRecord::StatementInvalid (PG::Error: ERROR:  syntax error at or near ")"
LINE 11:       AND localizations.id IN ();
                                        ^
:       UPDATE localizations
        SET published_version_id = latest_version.id,
        published_content = latest_version.content,
        updated_at = '2012-11-12 18:34:10.075543'
      FROM (
                SELECT DISTINCT ON (localization_id) localization_id, id, content
        FROM versions ORDER BY localization_id DESC, id DESC

        ) AS latest_version
      WHERE latest_version.localization_id = localizations.id
      AND localizations.id IN ();
):
  app/models/localization.rb:56:in `publish'
  app/models/project.rb:50:in `deploy!'
  app/controllers/api/v2/deploys_controller.rb:3:in `create'

Once I added a blurb to a view in the project and loaded the page, the deploy rake task worked fine, but a 500 error made me sad. I'll fix it a little later when I've got more time, but if anyone wants to take a stab at it, by all means! 😄
