Redmine

Hi,

Similarly to "Closed Date" field that was added recently, I need to record other key dates for tracking. For this I would need:

• "DateTime" Custom fields (as in: http://www.redmine.org/issues/11044)
• Trigger mechanism (eg on State change, update field)

I did not find existing solutions for these 2 items, so I have considered:

• Using a Custom field type "String" to record date times with a fixed predefined format (eg: 2013/09/01 16:41 UTC), quite easy in Ruby:
  dnow=DateTime.now
dnow.strftime("%Y-%m-%d %H-%M-%S UTC")
• For triggers, I thought I could add a method in issue.rb update(), but can't get it to work.
  2 problems: How to get the former state ? How to update the custom field ? I tried this:http://stackoverflow.com/questions/16958500/creating-and-populating-redmine-custom-fields-by-ruby-code but no luck my field is never updated (and I have big troubles understanding the code)

Did anyone code successfully such a mechanism ?

Thanks
