Redmine › Project Alias

ApplicationController uses the find_project method, which in turn uses Project.find, to find projects. For some reason, this way Redmine succeeds to find aliased projects on my local installation, but fails to do this on the server.

This caused multiple exceptions, e.g., when Redmine tried to access .wiki of null. Therefore, in ApplicationController#find_project method I replaced find with the patched find_by_identifier:

  # Find project of id params[:id]
  def find_project
    @project = Project.find_by_identifier(params[:id]) # <-- here
  rescue ActiveRecord::RecordNotFound
    render_404
  end

But, this is a temporary fix, that should be reverted!

Even so, Redmine still randomly fails to find the project and gives 403:

There are also other issues like:
