Update/Set/Edit Assignee field - value from custom field

[Rafal Unit4Teta]

Hi,

I try update assignee field on postfunction. I read several topics, but I have a problem still.

My code:

import com.atlassian.jira.component.ComponentAccessor
import org.apache.log4j.Level
import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.CustomFieldManager
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.fields.CustomField
import com.atlassian.fugue.Option
import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.ModifiedValue
import com.atlassian.jira.issue.MutableIssue
import com.atlassian.jira.issue.util.DefaultIssueChangeHolder
import com.onresolve.scriptrunner.runner.customisers.PluginModule
import com.onresolve.scriptrunner.runner.customisers.WithPlugin
import com.atlassian.jira.user.ApplicationUser
import com.atlassian.jira.issue.fields.layout.field.FieldLayoutItem
import com.atlassian.jira.issue.comments.CommentManager
import com.atlassian.jira.ComponentManager
import com.atlassian.jira.util.ImportUtils
import com.atlassian.jira.user.util.UserManager
import com.atlassian.crowd.embedded.api.User


log.setLevel(Level.DEBUG)
//Grab necessary Components
def cfm = ComponentAccessor.getCustomFieldManager()
def optionsManager = ComponentAccessor.getOptionsManager()
def userManager = ComponentAccessor.getUserManager()
def issueService = ComponentAccessor.getIssueService()

def RealizujacyCf = cfm.getCustomFieldObject(11701L)
log.info("RealizujacyCf: " + RealizujacyCf)
def RealizujacyValue = issue.getCustomFieldValue(RealizujacyCf)
log.info("RealizujacyValue: " + RealizujacyValue)
def ClassOfField = RealizujacyValue.getClass()
log.info("ClassOfField: " + ClassOfField)
def ArreySize = RealizujacyValue.size()
log.info("ArreySize: " + ArreySize)


def Realizujacy = issue.getCustomFieldValue(RealizujacyCf).get(0).getName()
log.info("Realizujacy: " + Realizujacy)
def cfWlasciciel = cfm.getCustomFieldObject(11100L)


def user = userManager.getUserByName(Realizujacy); 
def validateAssignResult = issueService.validateAssign(user, issue.id, issue.reporterId)
log.info("validateAssignResult: " + validateAssignResult)
//issueService.assign(user, validateAssignResult)

log.info("user: " + user)

//issue.store();

This line return the name of user, ex.: anowak(anowak),

def user = userManager.getUserByName(Realizujacy);

Now, I'd like to update assignee filed with value of "user ".

Without this line:

issueService.assign(user, validateAssignResult)

I have this result:

2019-03-26 16:27:39,829 INFO [workflow.ScriptWorkflowFunction]: RealizujacyCf: Realizujący
2019-03-26 16:27:39,830 INFO [workflow.ScriptWorkflowFunction]: RealizujacyValue: [anowak(anowak)]

2019-03-26 16:27:39,830 INFO [workflow.ScriptWorkflowFunction]: validateAssignResult: com.atlassian.jira.bc.issue.IssueService$AssignValidationResult@330196c2

But with this line:

issueService.assign(user, validateAssignResult)

I have this result:

Hi,

You are not using the correct method. I would advise to use : 

issue.setAssignee(user)

Thank you very much.

Right code looks like:

import com.atlassian.jira.component.ComponentAccessor
import org.apache.log4j.Level
import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.CustomFieldManager
import com.atlassian.jira.issue.Issue

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.ModifiedValue
import com.atlassian.jira.issue.MutableIssue
import com.atlassian.jira.issue.util.DefaultIssueChangeHolder
import com.onresolve.scriptrunner.runner.customisers.PluginModule
import com.onresolve.scriptrunner.runner.customisers.WithPlugin

def RealizujacyCf = cfm.getCustomFieldObject(11701L)
log.info("RealizujacyCf: " + RealizujacyCf)
def RealizujacyValue = issue.getCustomFieldValue(RealizujacyCf)
log.info("RealizujacyValue: " + RealizujacyValue)
def ClassOfField = RealizujacyValue.getClass()
log.info("ClassOfField: " + ClassOfField)
def ArreySize = RealizujacyValue.size()
log.info("ArreySize: " + ArreySize)

log.info("Realizujacy: " + Realizujacy)
def cfWlasciciel = cfm.getCustomFieldObject(11100L)


def user = userManager.getUserByName(Realizujacy);
log.info("user: " + user)
def validateAssignResult = issueService.validateAssign(user, issue.id, issue.reporterId)
log.info("validateAssignResult: " + validateAssignResult)
issue.setAssignee(user)

//issueService.assign(user, validateAssignResult)
//issue.store();
