ScriptRunner: How to update a custom field if Description changed? Edited

[Michael Voronkov]

Goal: identify all stories where Description field changed after certain date.

My thinking:

• Create a custom field (number) and update counter each time Description is updated
• Have ScriptRunner update the custom field on each Description update event
• Use JQL and generate report (the easy part)

STEP 1: Created custom field

  "id": "customfield_16800",
    "name": "DescriptionChange",
    "custom": true,
    "orderable": true,
    "navigable": true,
    "searchable": true,
    "clauseNames": [
      "cf[16800]",
      "DescriptionChange"
    ],
    "schema": {
      "type": "number",
      "custom": "com.atlassian.jira.plugin.system.customfieldtypes:float",
      "customId": 16800
    }

STEP 2: created Custom Listener (All Projects, "All Issue Events")

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.ModifiedValue
import com.atlassian.jira.issue.util.DefaultIssueChangeHolder

Issue issue = event.issue
def customFieldManager = ComponentAccessor.getCustomFieldManager()
def change = event?.getChangeLog()?.getRelated("ChildChangeItem").find {it.field == "Description"}

if (change)
{
    def tgtField = customFieldManager.getCustomFieldObjects(issue).find {it.name == "DescriptionChange"}
    def changeHolder = new DefaultIssueChangeHolder()
    tgtField.updateValue(null, issue, new ModifiedValue(issue.getCustomFieldValue(tgtField), 1), changeHolder)
}
else return

The script doesn not update Description field.  I am new to ScriptRunner and need some help with the script.

Thanks in advance!

You could do this entirely with a scripted field. This is a variation of this example in the docs here.

You'll need the following script below:

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.IssueFieldConstants

def changeHistoryManager = ComponentAccessor.getChangeHistoryManager()

def changeItems = changeHistoryManager.getChangeItemsForField(issue, IssueFieldConstants.DESCRIPTION)

if (changeItems) {
    def changeItem = changeItems.last()

    return new Date(changeItem.getCreated().time)
}

null

 You'll need to set your template and searcher to:

Template: Date Time picker
Searcher: Date Time Range picker

Then it should be just a case of crafting the right JQL to search on that field.

For your information ScriptRunner provides a number of JQL functions for comparing dates here. If you happen to have a more complex requirement in the future.

Hope this helps.

Hi Adam, thank you for the feedback.  During implementation of this functionality our requirement got refined into the following: Only track Description field changes during Active Sprint.  Should not track any changes before or after Active Sprint.

Here's the code for that:

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.event.issue.IssueEvent
import com.atlassian.jira.issue.ModifiedValue
import com.atlassian.jira.issue.util.DefaultIssueChangeHolder
import org.ofbiz.core.entity.GenericValue
import com.atlassian.core.util.map.EasyMap

def changeHistoryManager = ComponentAccessor.getChangeHistoryManager()
def event = (IssueEvent)event
def issue = event.issue
def customFieldManager = ComponentAccessor.getCustomFieldManager()

def sprintField = customFieldManager.getCustomFieldObjects(issue).find {it.name == "Sprint"}
if (sprintField)
{
    def state = issue.getCustomFieldValue(sprintField)?.state?.first().toString()
    if (state == "ACTIVE")
    {
        List<GenericValue> changeItems = null;
        try {
            GenericValue changeLog = event.getChangeLog()
            Map map = EasyMap.build("group", changeLog.get("id"))    
            changeItems = changeLog.getDelegator().findByAnd("ChangeItem", map)
            if(changeItems == null) {
                log.warn("nothing found")
            }
            for(GenericValue changeVal : changeItems) {
                String field = changeVal.getString("field")

                if (field == "description") {
                    log.warn("Detected change to description field")
                    def tgtField = customFieldManager.getCustomFieldObjects(issue).find {it.name == "DescriptionChange"}
                    log.warn("tgtField " + tgtField)
                    def changeHolder = new DefaultIssueChangeHolder()
                    Double num = (Double)(issue.getCustomFieldValue(tgtField))
                    if(num == null) {
                        num = 0;
                    }
                    log.warn("num " + num)
                    tgtField.updateValue(null, issue, new ModifiedValue(num, num + 1), changeHolder)
                }
            }
        } catch(Exception e) {

        }
    }
    else {return}
}
else {return}
