Redmine

This seems to be a problem triggered by running redmine in a subpath. To make redmine run in the subpath "/redmine", two things were done:

1. The line Redmine::Utils::relative_url_root = "/redmine" was added as last line of config/environment.rb
2. The workaround described here was used.

This adds the prefix "/redmine" to all links, but it misses the "Remove relation" link. However, even after adding the prefix, redmine can't route the DELETE-request: ActionController::RoutingError (No route matches [DELETE] "/redmine/relations/123456").

Hope this helps in fixing it.

This may be considered as resolved.

The problem was that routes to relations are shallow routes and the variable :shallow_path was not set accordingly. It would be nice if redmine would work in subdirectories again. Using a reverse proxy sadly is no option, because some paths are hardcoded into JS, which makes them hard to adjust.

I've posted an attempt of a solution here, but that is probably not the best way of resolving the issue.

According to http://stackoverflow.com/questions/6422677/rails-routes-with-scope-locale-and-shallow-nested-resources, you should be able to specify :shallow_path only once with your scope (not tested):

scope :path => "redmine", :shallow_path => "redmine" do
  ...
end

IIRC, there was no need to change the routes with Rails 2 for running in a suburi.
