Sums specified field in Roadmap and Milestone stats

Notice: This plugin is unmaintained and available for adoption.


This plugin combines the fields for the roadmap and milestone views. This is a complement to the Sum Fields plugin, which sums fields in a query or report. These plugins are useful when assessing progress based on "points" or "ideal days" of effort instead of ticket count.

This plugin now also provides a Google Visualization API data source that can populate a burndown chart on milestone pages such as provided by the Trac Visualization plugin. See more details below.

This plugin was inspired by the CustomRoadmapPlugin but overcomes its limitation of requiring a patch. Additionally, this plugin allows for any field to be used to define a group, not just the default status field. Lastly, this plugin was designed to be backward compatible with the default ticket count behavior, so that you can utilise as much or as little of its enhancements as required.

The plugin also provides a Google Visualization API data source at /sumstats/query that can populate a burndown chart. See below for an example.

You can check out SumStatsPlugin from here using Subversion, or browse the source with Trac.

Installation and Configuration

  1. Install the plugin, after downloading and unzipping:
    cd sumstatsplugin/0.12
    sudo python install

See TracPlugins for more installation details and options. You will likely need to restart Trac's web server after installation.

  1. Enable the plugin in your trac.ini file:
    sumstats.* = enabled

You can alternatively use the Trac Web Admin GUI.

  1. Replace the DefaultTicketGroupStatsProvider with this plugin's new SumTicketGroupStatsProvider in trac.ini:
    stats_provider = SumTicketGroupStatsProvider
    stats_provider = SumTicketGroupStatsProvider
  1. (Optional) Configure the main sumstats section in trac.ini:
    field = effort
    label = effort
    drilldown_label = Ticket effort
    filter = type!=epic
    query_args = col=summary,col=type,col=effort

The optional field option specifies which field to sum. The optional drilldown_label and label options are used to define the TicketGroupStats object. The optional filter is a list of additional global filters for all groups (if specified it's currently limited to standard fields only). The optional query_args is a convenient, comma-delimited list that gets appended to each group's query_args. See the examples below for more details.

  1. (Optional) Install the Google Visualization API Python gviz client library if using as a data source, see below.


Combining resolution and phase fields

Here is a sample trac.ini file that combines a custom phase field with a standard resolution field:

closed = fixed
closed.field = resolution
closed.label = fixed
closed.order = 1
closed.overall_completion = true

readying = *
readying.field = phase
readying.order = 2
readying.color = YellowGreen

implementation = implementation
implementation.field = phase
implementation.order = 3
implementation.color = Yellow

waiting = waiting
waiting.field = phase
waiting.order = 4
waiting.color = White

scoping = sizing,definition
scoping.field = phase
scoping.order = 5
scoping.color = Red

This plugin maintains the same syntax and semantics as the DefaultTicketGroupStatsProvider to support backwards compatibility and ease of transition. If the .field option is omitted, then the status field is presumed. Note that a .color option is required for each group (except for any default closed or new group you have). The "catch all" * value is also supported, although there are currently no checks for duplicate "catch all" or otherwise redundant group definitions.

Burndown chart data source

This plugin also provides a Google Visualization API data source using the Python Gviz client library (which must be installed separately) that can populate a daily, agile-style burndown chart. Being a standard Google Visualization API data source, it can be accessed and visualized anywhere. However, it can also display burndown charts on Trac milestone pages by using the Trac Visualization plugin, for example:

The data source reuses the filter option set in the [sumstats] section. See step 4 of the Configuration section above for more details. No additional configuration is required to enable the burndown data source. However, it currently makes the following assumptions:

  • "done" means closed as fixed
  • if a sum field is provided, then it's assumed to be a custom field (not a standard field)
  • if the milestone cannot be extracted from the referrer url, then the current milestone is assumed.

The data is accessed at:


The above request returns a data table (in JSON response format) of up to 4 columns:

  • day - the day
  • total - the total sum or count for the day (both marked as fixed and not closed)
  • todo - the remaining (i.e., not closed) sum or count for the day
  • done - the completed (i.e., closed as fixed) sum or count for the day

The default response includes the day, todo and done fields in that order. To change which fields are returned and/or their order, eg to display the data in alternatively configured charts, you can add a (partial) query, ie the tq portion below:

http://<your-trac-domain>/sumstats/query?tq=select total,done

Only the select phrase is used at this time to specify which columns to return and their order. The day field is always the first column and should be omitted from the select phrase. You may need to urlencode the tq value.

Let me know if you need additional flexibility in the query and I'll consider adding it. For example, ways to specify the milestone explicitly, a different timeframe grouping than daily, etc.
