How to Automatically create Sub - task using script runner post function?

[Chander Korshika]

Can someone help me in modifying below sample custom script that you can use in order to create a number of subtasks .My requirement is to create as per the value of customfield.

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.MutableIssue
import com.atlassian.jira.issue.customfields.manager.OptionsManager

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

Issue parentIssue = issue

if (parentIssue.getIssueTypeObject().getName() == 'Sub-task')
 return

if (parentIssue.getIssueTypeObject().name != 'Feature')
 return

def summariesList = ["Summary 1", "Summary 2", "Summary 3"]

// code in order to create the values to update a CascadingSelect custom field
def cascadingSelect = ComponentAccessor.customFieldManager.getCustomFieldObjectByName("CascadingSelect")
def fieldConfig = cascadingSelect?.getRelevantConfig(parentIssue)
def listOfOptions = ComponentAccessor.getComponent(OptionsManager).getOptions(fieldConfig)
def parentOption = listOfOptions?.find {it.value == "AAA"}
def childOption = parentOption?.getChildOptions()?.find {it.value == "A2"}

def mapWithValues = [:]
mapWithValues.put(null, parentOption)
mapWithValues.put('1', childOption)

summariesList.each {
 MutableIssue newSubTask = issueFactory.getIssue()
 newSubTask.setAssigneeId(parentIssue.assigneeId)
 newSubTask.setSummary(it)
 newSubTask.setParentObject(parentIssue)
 newSubTask.setProjectObject(parentIssue.getProjectObject())
 newSubTask.setIssueTypeId(constantManager.getAllIssueTypeObjects().find{
 it.getName() == "Sub-task"
 }.id)
 // Add any other fields you want for the newly created sub task
 newSubTask.setCustomFieldValue(cascadingSelect, mapWithValues)

 def newIssueParams = ["issue" : newSubTask] as Map<String,Object>
 
 //for JIRA v6.*
 issueManager.createIssueObject(user.directoryUser, newIssueParams)
 subTaskManager.createSubTaskIssueLink(parentIssue, newSubTask, user.directoryUser)
 // for JIRA v7.*
 issueManager.createIssueObject(user, newIssueParams)
 subTaskManager.createSubTaskIssueLink(parentIssue, newSubTask, user)

 log.info "Issue with summary ${newSubTask.summary} created"
}
