Advanced Ticket Workflow

Notice: This plugin is unmaintained and available for adoption.


This plugin provides a number of advanced operations to customise ticket workflows. They are an enhancement to the operations as part of the customizeable workflow of the Trac core system.

Currently provided operations are:

  • set_owner_to_reporter
  • set_owner_to_component_owner
  • set_owner_to_field
  • set_owner_to_previous
  • set_status_to_previous
  • set_field_to_author
  • reset_milestone
  • clear_fields
  • run_external
  • triage
  • xref

The meaning behind each of these operations is explained below.

The plugin can be installed in the same way as other plugins. The simplest is to create an egg as follows:

$ python bdist_egg

and copy the .egg file from the dist directory to your Trac environment's plugins directory.

Then enable the plugin in your trac.ini file:

advancedworkflow.* = enabled

Add the individual controller to the workflow controller list. For example, when using the operation set_owner_to_reporter, the TicketWorkflowOpOwnerReporter must be appended to the workflow controller list:

workflow = ConfigurableTicketWorkflow,TicketWorkflowOpOwnerReporter

The controller name is unique for each workflow operation and they can be found listed in parentheses after the operation name in the configuration section below. A controller must be added to the list for each workflow operation that is used.

And use the operation in your custom workflow:

needinfo = * -> needinfo = Need info
needinfo.operations = set_owner_to_reporter


The following are examples of custom workflow operations together with their controller name:

  • set_owner_to_reporter (TicketWorkflowOpOwnerReporter)

Sets the owner to the ticket reporter.

<someaction>.operations = set_owner_to_reporter
  • set_owner_to_component_owner (TicketWorkflowOpOwnerComponent)

Sets the owner to the ticket's component owner.

<someaction>.operations = set_owner_to_component_owner
  • set_owner_to_field (TicketWorkflowOpOwnerField)

Sets the owner to the value of a ticket field.

<someaction>.operations = set_owner_to_field
<someaction>.set_owner_to_field = mycustomfield
  • set_owner_to_previous (TicketWorkflowOpOwnerPrevious)

Sets the owner to the previous owner. If there is no previous owner, the owner will be deleted.

<someaction>.operations = set_owner_to_previous
  • set_status_to_previous (TicketWorkflowOpStatusPrevious)

Sets the status to the previous status. If there is no previous status, this is a no-op.

<someaction>.operations = set_status_to_previous
  • set_field_to_author (TicketWorkflowOpFieldAuthor)

Sets the value of a ticket field to the current user.

<someaction>.operations = set_field_to_author
<someaction>.set_field_to_author = myfield
  • reset_milestone (TicketWorkflowOpResetMilestone)

Will reset the milestone of a ticket if the milestone has been completed. This is useful for "reopen" actions.

<someaction>.operations = reset_milestone
  • clear_field (TicketWorkflowOpFieldsClear)

Clear the value of the ticket field(s).

<someaction>.operations = clear_fields
<someaction>.clear_fields = myfield_one, myfield_two
  • run_external (TicketWorkflowOpRunExternal)

Runs an external script <tracenv>/hooks/<someaction> passing the ticket number and the username as parameters. Security warning: If you have account registration available, your hook script must treat the username as user input.

<someaction>.operations = run_external
<someaction>.run_external = Hint to tell the user.
  • triage (TicketWorkflowOpTriage)

Sets the next status based on mapping the value of a field to a status value. For example, this can be used for a "triage" action that splits a workflow based on the ticket type:

<someaction> = somestatus -> *
<someaction>.operations = triage
<someaction>.triage_field = type
<someaction>.triage_split = defect->new_defect,task->new_task,enhancement->new_enhancement

The most common request is to use a different workflow based on the ticket type. Let's simplify that case slightly for the sake of this example and assume that there are only two ticket types, defect and enhancement. We'll say that defects require a qa step, but enhancements do not:

accept = new -> * = Accept ticket into workflow
accept.operations = triage
accept.triage_field = type
accept.triage_split = defect->new_defect,enhancement->new_enhancement

resolve_enh = new_enhancement -> closed = resolve
resolve_enh.operations = set_resolution

submittotest = new_defect -> qa = Submit to Test

resolve_def = qa -> closed = resolve
resolve_def.operations = set_resolution
  • xref (TicketWorkflowOpXRef)

Adds a comment to the ticket specified in the text field. Enter either the bare ticket number or '#' + ticket number. The format of the comment to be added to the other ticket is given as a Python string with a single %s in it. That format string defaults to 'Ticket %s is related to this ticket'.

Also adds a comment to the local ticket. The format of the comment for the local ticket can be specified with .xref_local; it defaults to 'Ticket %s was marked as related to this ticket'. This functionality can be disabled by setting .xref_local to an empty value.

Note that the implementation of this operation is not robust.

;displays as "closed as duplicate of [_________]"
dup = * -> closed = close
dup.operations = set_resolution,xref
dup.set_resolution = duplicate
dup.xref = Ticket %s has been marked as a duplicate of this ticket.
dup.xref_local = Closed as duplicate of %s.
