added a patch

Estimation and Time Tracking

Demo Site | User Manual | Open Tickets | new ticket


This is a plugin that adds (aspires to add) estimation and time tracking to Trac.

This basically adds CustomFields and CustomReports and an interface for filling the dynamic variables for the report. (requires javascript).

Supported Versions

Currently this has been tested on:

  • Python >=2.3
  • Trac >= .10
  • DB, should support all three major free backends
    • sqlite3 >= 3.2.3
    • MySql
    • PostgreSQL
  • Genshi
    • for trac 11 you need a Genshi >= 5
    • for trac 12 you need a Genshi >= 6 (Trac installs this automatically)

Getting the Plugin

Download the source using Svn at:

Download the zipped source :

When downloading these files the extention is lost, or the filename corrupted. 
  a simple rename to seems to resolve it the contents are intact

Browse the source using Trac:

In the repository there is a script folder 0.12/0.11 that contains some various python files that I have written to perform billing queries across an entire directory of tracs and email the results to a specified address. As is these are written to work in my setup and some paths at the top of each file will probably need to be changed. These are mostly included because I wrote them for myself and thought others might want to perform similar tasks. (See: script help)


Installation Help

  1. Install the plugin (either for a single project, or globally). See the details on how to install a trac plugin at: TracPlugins
  2. Be sure that the plugin is enabled. Add "timingandestimationplugin.* = enabled" to trac.ini (in the [components] subheading).
    • Alternatively, this can be enabled in the Web Admin section of the website as well
  3. Run $ trac-admin /path/to/projenv upgrade
    • You should get a message like this:
      Timing and Estimation needs an upgrade
      Upgrading Database
      Creating bill_date table
      Upgrading fields
      Upgrading reports
      Upgrading usermanual
      Done Upgrading
      Upgrade done.
  4. Reload/restart your HTTPD / other webserver / Tracd. That's it.

Post Installation Configuration Options


By default, the TimingAndEstimationPlugin's four components will all be active. However, you can disable some of the components if you want to. (The easiest way to do this is to ensure you have the trac:WebAdmin plugin installed.)

The plugin's components are:

  1. TimeTrackingSetupParticipant
    Required component.
  2. TimeTrackingTicketObserver
    Ensures that the "Total Hours" values are updated when a user edits a ticket's "Add Hours to Ticket" field. You would not normally want to disable this component.
  3. TicketWebUiAddon
  4. TimingEstimationAndBillingPage

Permissions (Trac>=11 only)
