Automatic subtask creation

[Marat]

Hi

I need to create several subtasks when creating a issue.
The number of subtasks depends on the filled in custom fields when creating a issue.
The user in the custom field must become a performer in subtasks

I saw in the scriptranner the possibility of creating subtasks, but it is difficult for me to figure out how to do what I described above.

pls Help)

You certainly will want an addon. Scriptrunner, Powerscripts, Automation for Jira all are good. I currently use the last one in this list and it is pretty easy to use. It is less "scripty". Bob Swift is coming out with one that focuses on "drag and drop" automation so that may be worth a look as well. It is best to assess you needs now and in the future, read the marketplace overviews and ultimately trial a few.

[Antoine Berry]

To add to what Jack said, if you choose scriptrunner or already have it, here is a snippet that creates subtasks. You would have to create a custom script postfunction. 

import com.atlassian.jira.component.ComponentAccessor

def constantManager = ComponentAccessor.getConstantsManager()
def issueManager = ComponentAccessor.getIssueManager()
def issueFactory = ComponentAccessor.getIssueFactory()
def subTaskManager = ComponentAccessor.getSubTaskManager()
def userManager = ComponentAccessor.getUserManager()

def numberOfSubtasksId = 11001
def numberOfSubtasks = customFieldManager.getCustomFieldObject(numberOfSubtasksId)
def numberOfSubtasksValue = issue.getCustomFieldValue(numberOfSubtasks)

def performerId = 11002
def performer = customFieldManager.getCustomFieldObject(performerId)
def performerValue = issue.getCustomFieldValue(performer)

for (int i=1; i<=numberOfSubtasksValue; i++){
MutableIssue newSubTask = issueFactory.getIssue()
newSubTask.setReporter(issue.reporter)
newSubTask.setAssignee(performerValue?.getKey())
newSubTask.setSummary("Subtask n°" + i)
newSubTask.setParentObject(issue)
newSubTask.setProjectObject(issue.getProjectObject())
newSubTask.setIssueTypeId(constantManager.getAllIssueTypeObjects().find{it.getName() == "Sub-task"}.id)
newSubTask.setDescription("Description for Subtask n°" + i)
Map<String,Object> newIssueParams = ["issue" : newSubTask] as Map<String,Object>
issueManager.createIssueObject(issue.reporter, newIssueParams)
subTaskManager.createSubTaskIssueLink(issue, newSubTask, issue.reporter)
}

Assuming numberOfSubtasks is a Number field and performer is a User picker (single).

Yes, we already have scriptrunner.
I have several custom fields "Person 1 - n "(User picker (single)) When a issue is created, it is necessary that subtasks are created depending on the filled "Person" fields and each Person becomes an executor in a subtask.

[Antoine Berry]

How do you know how many subtasks you want to create ?

[Marat]

That is the problem.
if three fields were filled
Person1
Person2
Person3
then there should be three subtasks
for Person 1-3.

[Antoine Berry]

Then you can use this (10001,10002,10003 being the custom field ids).

import com.atlassian.jira.component.ComponentAccessor

def constantManager = ComponentAccessor.getConstantsManager()
def issueManager = ComponentAccessor.getIssueManager()
def issueFactory = ComponentAccessor.getIssueFactory()
def subTaskManager = ComponentAccessor.getSubTaskManager()

def personFieldsIds = [10001,10002,10003]

for (int personFieldsId:personFieldsIds){
def person = customFieldManager.getCustomFieldObject(personFieldsId)
def personValue = issue.getCustomFieldValue(person)
if (personValue){
MutableIssue newSubTask = issueFactory.getIssue()
newSubTask.setReporter(issue.reporter)
newSubTask.setAssignee(personValue?.getKey())
newSubTask.setSummary("Subtask for " + personValue?.getDisplayName())
newSubTask.setParentObject(issue)
newSubTask.setProjectObject(issue.getProjectObject())
newSubTask.setIssueTypeId(constantManager.getAllIssueTypeObjects().find{it.getName() == "Sub-task"}.id)
newSubTask.setDescription("Description for " + personValue?.getDisplayName())
Map<String,Object> newIssueParams = ["issue" : newSubTask] as Map<String,Object>
issueManager.createIssueObject(issue.reporter, newIssueParams)
subTaskManager.createSubTaskIssueLink(issue, newSubTask, issue.reporter)
}
}

 Also you could use a multi user field instead of three single ones.

This script does not work for me. The validator accepted it, but subtasks are not created. What am I doing wrong ? Maybe affairs in the Jira version? My version v6.3.10

[Antoine Berry]

That might be because of the version indeed, I am working on 7.6. Could you please take a look into the logs and paste the error here ?

Please add

@Antoine Berry  any idea?

[Antoine Berry]

Hi @Marat , sorry I was out of office.

Please add : 

def customFieldManager = ComponentAccessor.getCustomFieldManager()

Antoine

[Marat]

Thank you for continuing to answer me))

That didn't help either

[Antoine Berry]

Please save as is, these warnings appear beacuse we did not specify the class of the object, but it should not be a problem at execution time.

[Antoine Berry]

Is your field a single user picker ? 

Can you add 

log.error("personValue : " + personValue)
log.error("personValue class : " + personValue.getClass())

before the setAssignee line and paste the logs again ?

Please replace setAssignee line with : 

newSubTask.setAssignee(personValue)

 or 

newSubTask.setAssigneeId(personValue?.getKey())

[Antoine Berry]

So first option seems to work for Assignee, the error is not the same. Where are you calling this script ? It seems that issue object is null.

[Marat]

The script is written in the post function when creating a issue.

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

def constantManager = ComponentAccessor.getConstantsManager()
def issueManager = ComponentAccessor.getIssueManager()
def issueFactory = ComponentAccessor.getIssueFactory()
def subTaskManager = ComponentAccessor.getSubTaskManager()
def customFieldManager = ComponentAccessor.getCustomFieldManager()

def personFieldsIds = [14098,14099]

for (int personFieldsId:personFieldsIds){
def person = customFieldManager.getCustomFieldObject(personFieldsId)
def personValue = issue.getCustomFieldValue(person)
if (personValue){
MutableIssue newSubTask = issueFactory.getIssue()
newSubTask.setReporter(issue.reporter)
log.error("personValue : " + personValue)
log.error("personValue class : " + personValue.getClass())
newSubTask.setAssigneeId(personValue?.getKey())
newSubTask.setSummary("Subtask for " + personValue?.getDisplayName())
newSubTask.setParentObject(issue)
newSubTask.setProjectObject(issue.getProjectObject())
newSubTask.setIssueTypeId(constantManager.getAllIssueTypeObjects().find{it.getName() == "Sub-task"}.id)
newSubTask.setDescription("Description for " + personValue?.getDisplayName())
Map<String,Object> newIssueParams = ["issue" : newSubTask] as Map<String,Object>
issueManager.createIssueObject(issue.reporter, newIssueParams)
subTaskManager.createSubTaskIssueLink(issue, newSubTask, issue.reporter)
}
}

Can you please provide a screenshot of your transition post functions ? The script post function should be after the "Creates the issue originally.".

Antoine

[Marat]

Moved script post function after the "Creates the issue originally." and got a new error))
