Redmine

In task for migrate projects from Trac v0.8.x to redmine, I get following error:

Migrating components........
Migrating milestones.rake aborted!
undefined method `description' for #<TracMigrate::TracMilestone:0xb7026590>

For resolved this problem, I create a patch that fix this error.

      class TracMilestone < ActiveRecord::Base
        set_table_name :milestone

        def due
          if read_attribute(:due) && read_attribute(:due) > 0
            Time.at(read_attribute(:due)).to_date
          else
            nil
          end
        end

        def description
          return read_attribute(:descr) if has_attribute?(:descr) # Only Trac v0.8.x
          read_attribute(:description)
        end
      end

It's work.
