ScriptRunner for Jira (Server)

You might find Smart Checklist integration with ScripRunner useful for updating checklists using automated scripts. 

Basic Case

However, if the issue has no checklist set yet - it's possible to initiate initial rendering by pushing value to the custom field.

1. Setup "Checklists" custom field. Check instructions here "Checklists" Custom Field
2.  

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

def customFieldManager = ComponentAccessor.getCustomFieldManager()
def issueManager = ComponentAccessor.getIssueManager()

def issue = issueManager.getIssueObject("PROJ-7")
def changeHolder = new DefaultIssueChangeHolder()
def String myval = "- ToDo List\n+ Checked\nx Skipped\n~ In Progress\n# Another ToDo List\n- Unchecked\n> Quote line 1 https://rw.rw\\n> Quote line 2\n> Quote line 3\n"

// a text field
def textCf = customFieldManager.getCustomFieldObjectByName("Checklists")
textCf.updateValue(null, issue, new ModifiedValue(issue.getCustomFieldValue(textCf), myval),changeHolder)

Result

Update/append checklist with post function during a workflow status change.

This could be achieved by updating Issue Property with the key com.railsware.SmartChecklist.checklist using REST API Endpoints https://scriptrunner.adaptavist.com/5.6.8/jira/rest-endpoints.html

Set Checklist depending on Custom Field Value after Issue Creation

If you want the specific Checklist appended to your newly created ticket depending on the other Custom field value - you can easily do it by adding Script Runner Post Function to your Create Ticket workflow transition.

Check it out!

Assume that you have a custom field named "Environment" with 2 values: Production/Staging. So you expect that while adding a new issue - you'll have a proper checklist assigned

Result

Here's an implementation flow

1. Go To Workflow Editor
   
2. Choose "Script Post Function" Script Runner
   

3. Choose "Custom Script Post Function"

   

4. Add inline Script
   

5. Variables checklistProd and checklistStage used for keeping the proper value of the checklist (in text format)

   ScriptRunner

   import com.atlassian.jira.component.ComponentAccessor
   import com.atlassian.jira.issue.ModifiedValue
   import com.atlassian.jira.issue.util.DefaultIssueChangeHolder
   import org.apache.log4j.Level
   
   log.setLevel(Level.DEBUG)
   
   //Grab necessary Components
   def cfm = ComponentAccessor.getCustomFieldManager()
   def optionsManager = ComponentAccessor.getOptionsManager()
   
   def cfEnv = cfm.getCustomFieldObjectByName("Environment")
   def cfEnvtValue = issue.getCustomFieldValue(cfEnv)
   def cfEnvValueString = cfEnvtValue.toString()
   def changeHolder = new DefaultIssueChangeHolder()
   
   def checklistProd = "- ToDo List\n+ Checked\nx Skipped\n~ In Progress\n# Another ToDo List\n- Unchecked\n> Quote line 1 https://rw.rw\\n> Quote line 2\n> Quote line 3\n"
   def checklistStage = "- Uno\n+ Dos\nx Tres\n~ Quatro\n"
   
   
   log.info("checklistProd: " + checklistProd)
   log.info("checklistStage: " + checklistStage)
   log.info("Environment"+ cfEnvValueString)
   
   
   if (cfEnvValueString == "Production") {
   	//Set custom text field
   	def cfClient = cfm.getCustomFieldObjectByName("Checklists")
   	issue.setCustomFieldValue(cfClient,checklistProd)
   } else if (cfEnvValueString == "Staging") {
   	//Set custom text field
   	def cfClient = cfm.getCustomFieldObjectByName("Checklists")
   	issue.setCustomFieldValue(cfClient,checklistStage)
   }
   
   

6. Save the script. IMPORTANT! Make the Post Function is placed as a #1 Step!
