Abstract Design Goal

My goal in writing this plugin was to use as much of the existing structure as possible (therefore not needing to add extra structure that might make maintainability difficult). The largest downside I have found to this is that there is no way to attach more permissions to anything.

Custom Ticket Fields

In adhering to our design goal, rather than creating a new ticket interface, I create some custom fields and a small daemon to watch over them.

Fields:

• Hours to Add This field functions as a time tracker. When you add hours to it , those hours get added to the total hours field. The person who made the change is there fore credited with the hours spent on it.
• Total Hours This field is the total number of hours that have been added to the project. This has been made uneditable by including javascript which replaces the input box with a span containing its value
  • Reports might not agree with each other if this is manually edited (which is possible if you disable javascript).
• Is this billable? An extra flag on tickets so that they can be marked as billable / not billable.
• Estimated Hours a field that contains the estimated amount of work

Future Fields

• Ticket Rate The ability to attach a cost per hour or total amount to an individual ticket

Billing / Management Page / Time Reports

This page provide a small interface for querying the tickets and adding a bill date at the current time. This interface mostly just gives you links that match the interface to open any of the give reports, providing it the correct set of input parameters

The direct url is '/Billing'.

No Permissions Branch

The 'Management' button should be in the main title bar. It is possible that if you are viewing at a low resolution, it was pushed off the edge of the screen. Also if you are not logged in with report_view permissions, it will not show that button.

Permissions Branch

The 'Time Reports' button should be in the main title bar. Whether or not you see this will be based on whether your user has TIME_VIEW permissions.

Set Bill Date

This button will add now as a bill date. This is mostly to make it easier to select the last time you billed.

Reports

Report Types

We provide a few different reports for querying different types of data:

• Billing Reports Currently the billing reports are the only time based reports, and are therefore useful for getting an estimate what tickets had times (and totals), and which developers spent their time where.
  • Ticket Work Summary
  • Milestone Work Summary
  • Developer Work Summary
• Ticket/Hour? Reports These reports are useful for reviewing estimates on a large scale or getting an idea of the project at large. These reports currently ignore the time.
  • Ticket Hours
  • Ticket Hours with Description
  • Ticket Hours Grouped By Component
  • Ticket Hours Grouped By Component with Description
  • Ticket Hours Grouped By Milestone
  • Ticket Hours Grouped By Milestone with Description

Adding More Reports

To add reports to the Management screen sections, you must run the following sql against your trac database Remember to fill in the @reportID of the report you want to insert, and to select the insert statement for the section of your choice.

• INSERT INTO custom_report (id, uuid, maingroup, subgroup, version, ordering) VALUES (@reportID , @uuid, 'Timing and Estimation Plugin', 'Billing Reports', 1, 0);
• INSERT INTO custom_report (id, uuid, maingroup, subgroup, version, ordering) VALUES (@reportID , @uuid, 'Timing and Estimation Plugin', 'Ticket/Hour Reports', 1, 0);

NB: @uuid is a globally uninque identifier created via a tool such as uuidgen on Linux or various ​online tools. It is used in this plugin to provide programatic reference to specific reports such that they can be upgraded successfully on future revisions of the plugin

Removing a Report

To remove reports from the Management page, run the following query. Remember to fill in the @reportID of the report you want to modify.

• To remove for this version of the plugin (will be over written in future plugin upgrades)
  • UPDATE custom_report SET maingroup='x'||maingroup WHERE report = @reportID;
• To remove permanently (wont be over written in future plugin upgrades)
  • UPDATE custom_report SET version=9999, maingroup='x'||maingroup WHERE report = @reportID;

NB: The 'x' part is not important - you just need to make the column read something other than 'Timing and Estimation Plugin'.

TAKE NOTE

The reports can only be called from the Management Page. They will not work from the Trac View Tickets page. (Due to the custom variables that need values).

Permissions Branch

Recently a branch of this plugin was sponsored by ​Obsidian Software so that it would support per field permissions.

This is accomplished with Genshi 5 stream filters in trac 11. This code draws from the ​BlackMagicTicketTweaksPlugin

Configuration

There is a new trac.ini configuration section which is filled in by default as follows.

[field settings] # per field permissions

# a list of all the fields to apply permissions to
fields = billable, totalhours, hours, estimatedhours, internal

# a bunch of:
# field.permission = PERMISSION:consequence
#
#  If PERMISSION=ALWAYS, then the consequence always occurs
#    eg: billable.permission = ALWAYS:hide 
#        will always result in billable being hidden, irrespective of user permissions    
#
# where consequence is one of: hide, remove, disable
#    hide - replaces with hidden input
#    remove - removes element
#    disable - removes input in favor of text
billable.permission = TIME_VIEW:hide, TIME_RECORD:disable
totalhours.permission = TIME_VIEW:remove, TIME_RECORD:disable
hours.permission = TIME_VIEW:remove, TIME_RECORD:disable
estimatedhours.permission = TIME_RECORD:disable
internal.permission = TIME_RECORD:hide

It also adds an "Internal" checkbox which allows you to set a ticket as internal. For this policy to work correctly you need to add a line to the trac section of the config telling it which permission policies to use. (The setup will attempt to put this line of configuration in place. ) The permission that looks at currently is 'TIME_ADMIN'. To change that group set the internalgroup of the ticket section in the trac.ini as follows:

[ticket]
internalgroup = TRAC_ADMIN #or whatever group / permission you want

[trac]
permission_policies = InternalTicketsPolicy, DefaultPermissionPolicy, LegacyAttachmentPolicy
