Redmine

Currently, there are at least two places where links to the different objects are generated:

• the link_to_OBJECT methods in application_helper.rb
• the huge case statement in parse_redmine_links in application_helper.rb

Both of these places use independent code. This code should be merged into a consistent view. Today, both link types differ at least in its class attributes which makes themeing harder.

The attached patch fixes this for the link_to_attachment and the link_to_revision methods.
