I’ve an improvement proposal: It would be cool if it also read and transformed the following custom ticket fields from ticket_custom (don’t remember what Trac plugin provides them): * estimatedhours: the esimated number of hours a task will take to complete * totalhours: number of hours spend so far on the ticket implementation/resolution * blockedby: comma separated numbers of tickets that block this one (a similar attribute from another extension is “dependencies”)

I’d implement those ehnancements myself but don’t know Ruby.

I cleaned up your comments :-) You should get a GitHub account and fork that script. It'd be awesome and useful for everyone.</p> Radek: Thanks for trying it out!

Just a few remarks (I never used Ruby before): 1)With @milestone_task.start = Date.today, you can easily get end date before start date and gantty-0.1.8 didn’t like it.

2) Empty timepoint causes division by zero in @milestone_task.percent_complete = ((uncompleted_tickets.count.to_f / all_tickets.count.to_f) * 100).to_i

so I fixed it like this:

if all_tickets.count.to_i != 0 @milestone_task.percent_complete = ((uncompleted_tickets.count.to_f / all_tickets.count.to_f) * 100).to_i else @milestone_task.percent_complete = 0 end
