Question

I’ve recently migrated from Trav 0.12 to Redmine 1.4.0.
After migrating data from Rrac to Redmine I get this error:

I am new to ruby, can anyone help me?

Note: here is very similar problem described. In my case I use MySQL database instead.

Patch to migrate_from_trac.rake

class ::Time
    class << self
      alias :real_at :at
      alias :real_now :now
      # Fixing import for trac 0.12
      def at(time)
        d = nil
        if time > 10000000000 then
            d = real_at(time / 1000000, time % 1000000)
        else
            d = real_at(time) 
        end
        d
      end
      def now
        real_now - @fake_diff.to_i
      end
      def fake(time)
        time = 0 if time.nil?
        @fake_diff = real_now - time
        res = yield
        @fake_diff = 0
       res
      end
    end
  end
