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

1. Adding a SIL Post Function

We will assume that you already have a project and a workflow associated with it in your Jira installation. If you don't, please refer to Jira documentation on how to do that.

Now create a draft for the workflow and go to 'Create' transition.

Let's add a new post function. Under the "Post-functions" tab, click "Add" and choose "(k) SIL™ Post-function".

2. Writing the code

After you have added the post function, you are now ready to write the actual code. Immediately after the addition of the post function, you will be presented with our friendly user interface . Now give your program an appropriate name. This will be used as a base for the name of the file where the program will be saved. See Writing Conditions Validators and Post Functions for more examples.

For assigning the issue preserving the user load, you should write 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;

That's it! Click the "Add" button and you're ready to test your program.

3. Testing 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.

4. Assigning 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);
}
