Assign an issue preserving the user load

Problem

You want to assign new issues to the user with the least number of tasks to balance the workload across the team.

Solution

This recipe assumes that you already have a project and a workflow associated with it in your Jira installation. If not, go to the Jira documentation to find out how to do this.

Add a SIL post function

Create a draft workflow.
Go to the Create transition.
On the Post Functions tab, select the Add checkbox.
Select (k) SIL Post-function and click Add.

For more information on configuring workflows, go to the Atlassian documentation.

Write the code

After the you’ve added the post function, the user interface is displayed.

Enter a name for your program. This is used in the name of the file where the program is saved. For more examples, go to Writing Conditions Validators and Post Functions.

To assign an issue while also maintaining the user load, enter the following code.

string[] prjMembers = projectMembers(project);
string minUser;
number minIssues = -1;
number issuesNumber = -1;
string query = "project = " + project + " AND status in ('Open', 'In Progress', 'Reopened') AND assignee = ";
string jql;
 
for (string user in prjMembers) {
  jql = query + user;
  issuesNumber = arraySize(selectIssues(jql));
  if ((minIssues == -1) || (issuesNumber < minIssues)) {
    minIssues = issuesNumber;
    minUser = user;
  }
}
 
assignee = minUser;

Click Add.

It is recommended that you move all SIL™ Post Functions after all other post functions. You can do that by repeatedly clicking "Move Down" until it is at the very bottom of the post functions list.

Test the code

Next, activate your draft workflow by publishing it.

To test the post function, create a new issue. Fill the required fields and click "Create" button. The issue will be assigned to the user with the least number of tasks.

Assign an issue randomly to project users (example)

Recently we encountered one case where we needed the issue to be assigned randomly to project users.

For assigning the issue randomly, you should use the random function and write the following code:

string[] prjMembers = projectMembers(project);
number n = arraySize(prjMembers);
 
if (n > 0) {
 assignee = arrayGetElement(prjMembers, random(n));
} else {
 assignee = projectPM(project);
}
