Fix upload redirections when project has moved
Previously if a user attempted to click on a link to an attachment for a
renamed project (e.g. https://gitlab-org/gitlab-ce/uploads/123.png
),
Rails would redirect the user to an erroneous URL
(e.g. https://gitlab-org/gitlab-foss/uploads/123.png.png
). Notice the
redirect URL contains a redundant extension.
It turns out Rails 5 parses the extension of a route as the format (https://github.com/rails/rails/issues/28901#issuecomment-297747521), and the URL generator appends the format to the redirected route.
To fix this, we need to disable the format path parameter and explicitly
set the format to nil
. If we do not set the format to nil
, the URL
generator will append a query string (e.g ?format=png
), which would
still work but not necessary.
