Get user/author who last changed Assignee field

[-]

Hi all,

Our team utilizes Scriptrunner and JMWE plugins. I want to create a custom scripted field that stores the user/author that last changed the value of the Assignee field.

Referencing this community post from a couple years ago:https://community.atlassian.com/t5/Jira-questions/How-to-get-previous-changed-custom-field-data/qaq-p/829463

I figured this might be a step in the right direction:

import com.atlassian.jira.component.ComponentAccessor

def changeHistoryManager = com.atlassian.jira.component.ComponentAccessor.getChangeHistoryManager()
def old = changeHistoryManager.getChangeItemsForField(issue, 'Assignee')
return old.fromString

However, this doesn't seem to return anything. It only returns 'Anonymous' when tested on an issue in which a user (JohnD) manually changed the value of Assignee. I want this to be able to return the user who last changed the Assignee field.

Is this possible?

Hi @Ian Balas 

You can get a timePerfomed value.

Below is a scriptrunner library example used to build a past assignees panel

import com.atlassian.jira.avatar.AvatarService
import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.config.properties.APKeys
import com.atlassian.jira.issue.Issue
import groovy.xml.MarkupBuilder

import java.time.format.DateTimeFormatter
import static com.atlassian.jira.issue.IssueFieldConstants.ASSIGNEE

// the upper limited on the assignees to be displayed
final int historyDepth = 15
List<String> fields = new ArrayList<String>()
fields.add(ASSIGNEE)

def issue = context.issue as Issue
def counter = 0
List<Issue> issues = new ArrayList<Issue>()
issues.add(issue)

def baseUrl = ComponentAccessor.applicationProperties.getString(APKeys.JIRA_BASEURL)
def avatarService = ComponentAccessor.getComponent(AvatarService)
def loggedInUser = ComponentAccessor.jiraAuthenticationContext.loggedInUser

new MarkupBuilder(writer).table {
ComponentAccessor.changeHistoryManager.getChangeItemsWithFieldsForIssues(issues, fields).reverseEach {
def changeItems = it.changeItems

if (changeItems && !changeItems.isEmpty()) {
//if (changeItems.field.first() == ASSIGNEE && changeItems.newstring.first() && counter < historyDepth) {
def user = ComponentAccessor.userManager.getUserByName(changeItems.newvalue[0] as String)
def format = DateTimeFormatter.ofPattern("dd/MMM/yyyy")
def date = it.timePerformed.toLocalDateTime().toLocalDate()
if (user) {
tr {
td(
style: "width: 90px;", date.format(format)
)
td(
class: "jira-user-name user-hover jira-user-avatar jira-user-avatar-small",
rel : "admin", "id": "project-vignette_admin",
style: "margin: 1px 0px 1px 0px; height: 24px;",
href : "$baseUrl/secure/ViewProfile.jspa?name=$user.name"
) {
span(
class: "aui-avatar aui-avatar-small"
) {
span(
class: "aui-avatar-inner"
) {
img(
src: avatarService.getAvatarURL(loggedInUser, user),
alt: user.name
)
}
}
}
td(
user.displayName
)
}
}
}
counter++
// }
}
}
