Set assignee based on field value

[Callum Carlile _Automation Consultants_]

I need to insert a post function into a workflow that says if a custom field value is <200, set the assignee to Person A, and if the value is greater than or equal to 200, set the assignee to Person B.

I have scriptrunner, please may someone help me with this script!

Hi @Fazila Ashraf, thanks for your reply.

In that code;

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

String userName;

switch(ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName("fieldname").toString()){
    case "1": userName = "user1";break;
    case "2": userName = "user2";break;
    case "3": userName = "user3";break;    
}

issue.setAssignee(ComponentAccessor.getUserManager().getUserByName(userName))

I am not sure where/how to define the different cases. I think i should be using the statements 

if (number >= 200)

and

if (number < 200)

somewhere in the code, but I am unsure how to incorporate this. I'm afraid I am very new to ScriptRunner and groovy, any help would be hugely appreciated!

Yes, you should be using an 'If .. else" statement for your use case

I have got the following code:

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.MutableIssue
import com.atlassian.jira.issue.CustomFieldManager
import com.atlassian.jira.user.util.UserManager
import com.atlassian.jira.issue.IssueManager
import com.atlassian.jira.issue.MutableIssue
import com.atlassian.jira.event.type.EventDispatchOption

def number = ComponentAccessor.getCustomFieldManager().getCustomFieldObject("customfield_10202").getValue(issue)
if ((int) number >= 200){
 issue.setAssignee(ComponentAccessor.getUserManager().getUserByName("francismiers")) 
}
else{
 issue.setAssignee(ComponentAccessor.getUserManager().getUserByName("charlotteflowerdew"))
}

log.error(number)

The error from the log says: "Cannot invoke method getValue() on null object".

I'm sure this is a minor detail I have got wrong, but like i said i am new to groovy so any advice would be apprieciated.

For anyone else interested, the code below worked for me:

import com.atlassian.jira.component.ComponentAccessor

log.info(issue)

def customFieldManager = ComponentAccessor.getCustomFieldManager()
def customField = customFieldManager.getCustomFieldObjectByName("Value (£)")

def number = customField.getValue(issue)

if ((int) number >= 200){
 issue.setAssignee(ComponentAccessor.getUserManager().getUserByName("Username A")) 
}
else{
 issue.setAssignee(ComponentAccessor.getUserManager().getUserByName("Username B"))
}
