| 106 | | For actions that should be available in all states, `*` may be used in place of the state. The obvious example is the `leave` action: |
| 107 | | {{{ |
| 108 | | leave = * -> * |
| 109 | | leave.operations = leave_status |
| 110 | | leave.default = 1 |
| 111 | | }}} |
| 112 | | This also shows the use of the `.default` attribute. This value is expected to be an integer, and the order in which the actions are displayed is determined by this value. The action with the highest `.default` value is listed first, and is selected by default. The rest of the actions are listed in order of decreasing `.default` values. |
| 113 | | If not specified for an action, `.default` is 0. The value may be negative. |
| 114 | | |
| 115 | | There are a couple of hard-coded constraints to the workflow. In particular, tickets are created with status `new`, and tickets are expected to have a `closed` state. Further, the default reports/queries treat any state other than `closed` as an open state. |
| 116 | | |
| 117 | | While creating or modifying a ticket workflow, `contrib/workflow/workflow_parser.py` may be useful. It can create `.dot` files that [http://www.graphviz.org GraphViz] understands to provide a visual description of the workflow. |
| 118 | | |
| 119 | | This can be done as follows (your install path may be different). |

| | 112 | |
| | 113 | The special `_reset` action is added by default for tickets that are in states that are no longer defined. This allows tickets to be individually "repaired" after the workflow is changed, although it's recommended that the administrator perform the action by batch modifying the affected tickets. By default the `_reset` action is available to users with the `TICKET_ADMIN` permission and reset tickets are put in the //new// state. The default `_reset` action is equivalent to the following `[ticket-workflow]` action definition: |
| | 114 | {{{#!ini |
| | 115 | _reset = -> new |
| | 116 | _reset.name = reset |
| | 117 | _reset.operations = reset_workflow |
| | 118 | _reset.permissions = TICKET_ADMIN |
| | 119 | _reset.default = 0 |
| | 120 | }}} |
| | 121 | |
| | 122 | Since [trac:milestone:1.0.3] the `_reset` action can be customized by redefining the implicit action. For example, to allow anyone with `TICKET_MODIFY` to perform the `_reset` action, the workflow action would need to be defined: |
| | 123 | {{{#!ini |
| | 124 | _reset = -> new |
| | 125 | _reset.name = reset |
| | 126 | _reset.operations = reset_workflow |
| | 127 | _reset.permissions = TICKET_MODIFY |
| | 128 | _reset.default = 0 |
| | 129 | }}} |

| | 131 | == Workflow Visualization |
| | 132 | |
| | 133 | Workflows can be visualized by rendering them on the wiki using the [WikiMacros#Workflow-macro Workflow macro]. |
| | 134 | |
| | 135 | Workflows can also be visualized using the `contrib/workflow/workflow_parser.py` script. The script outputs `.dot` files that [http://www.graphviz.org GraphViz] understands. The script can be used as follows (your install path may be different): |
| | 136 | {{{#!sh |
| 124 | | And then open up the resulting `trac.pdf` file created by the script (it will be in the same directory as the `trac.ini` file). |
| 125 | | |
| 126 | | An online copy of the workflow parser is available at http://foss.wush.net/cgi-bin/visual-workflow.pl |
| 127 | | |
| 128 | | After you have changed a workflow, you need to restart apache for the changes to take effect. This is important, because the changes will still show up when you run your script, but all the old workflow steps will still be there until the server is restarted. |
| | 140 | And then open up the resulting `trac.pdf` file created by the script. It will be in the same directory as the `trac.ini` file. |
| | 141 | |
| | 142 | After you have changed a workflow, you need to restart your webserver for the changes to take effect. |
| 239 | | If you add additional states to your workflow, you may want to customize your milestone progress bars as well. See [TracIni#milestone-groups-section TracIni]. |

| 242 | | |
| 243 | | New enhancement ideas for the workflow system should be filed as enhancement tickets against the `ticket system` component. If desired, add a single-line link to that ticket here. Also look at the [http://trac-hacks.org/wiki/AdvancedTicketWorkflowPlugin AdvancedTicketWorkflowPlugin] as it provides experimental operations. |
| 244 | | |
| 245 | | If you have a response to the comments below, create an enhancement ticket, and replace the description below with a link to the ticket. |
| 246 | | |
| 247 | | * the "operation" could be on the nodes, possible operations are: |
| 248 | | * '''preops''': automatic, before entering the state/activity |
| 249 | | * '''postops''': automatic, when leaving the state/activity |
| 250 | | * '''actions''': can be chosen by the owner in the list at the bottom, and/or drop-down/pop-up together with the default actions of leaving the node on one of the arrows. |
| 251 | | ''This appears to add complexity without adding functionality; please provide a detailed example where these additions allow something currently impossible to implement.'' |
| 252 | | |
| 253 | | * operations could be anything: sum up the time used for the activity, or just write some statistical fields like |
| 254 | | ''A workflow plugin can add an arbitrary workflow operation, so this is already possible.'' |
| 255 | | |
| 256 | | * set_actor should be an operation allowing to set the owner, e.g. as a "preop": |
| 257 | | * either to a role, a person |
| 258 | | * entered fix at define time, or at run time, e.g. out of a field, or select. |
| 259 | | ''This is either duplicating the existing `set_owner` operation, or needs to be clarified.'' |
| 260 | | |
| 261 | | * Actions should be selectable based on the ticket type (different Workflows for different tickets) |
| 262 | | ''Look into the [http://trac-hacks.org/wiki/AdvancedTicketWorkflowPlugin AdvancedTicketWorkflowPlugin]'s `triage` operation.'' |
| 263 | | |
| 264 | | * I'd wish to have an option to perform automatic status changes. In my case, I do not want to start with "new", but with "assigned". So tickets in state "new" should automatically go into state "assigned". Or is there already a way to do this and I just missed it? |
| 265 | | ''Have a look at [http://trac-hacks.org/wiki/TicketCreationStatusPlugin TicketCreationStatusPlugin] and [http://trac-hacks.org/wiki/TicketConditionalCreationStatusPlugin TicketConditionalCreationStatusPlugin]'' |
| 266 | | |
| 267 | | * I added a 'testing' state. A tester can close the ticket or reject it. I'd like the transition from testing to rejected to set the owner to the person that put the ticket in 'testing'. The [http://trac-hacks.org/wiki/AdvancedTicketWorkflowPlugin AdvancedTicketWorkflowPlugin] is close with set_owner_to_field, but we need something like set_field_to_owner. |
| 268 | | |
| 269 | | * I'd like to track the time a ticket is in each state, adding up 'disjoints' intervals in the same state. |
| | 253 | If you add additional states to your workflow, you may want to customize your milestone progress bars as well. See [TracIni#milestone-groups-section TracIni]. |
