Expression

Jira expression:

issue?.parent ? issue?.parent.created.toCalendarDate().toString() : ""

Details

1. What does the expression do?

This expression retrieves the creation date of the parent of the current work item. If the current work item does not have a parent, it returns an empty string.

2. Step-by-step breakdown

Let’s break it down:

  • issue?.parent: This checks if the current work item has a parent.

  • ? ... : ...: This is a conditional (ternary) operator. It works like "if ... then ... else ...".

    • If issue?.parent exists (the work item has a parent), then:

      • issue?.parent.created: Gets the creation date of the parent.

      • .toCalendarDate(): Converts the creation date to a calendar date format (removing the time part).

      • .toString(): Converts the date to a readable text format.

    • If issue?.parent does not exist (no parent epic), then:

      • "": Returns an empty string.

3. Examples

  • If a work item has a parent epic created on January 10, 2024, the expression will display: 10/Jan/24.

  • If a work item does not have a parent epic, the expression will be displayed as “None”.

4. Real-life use cases

  • Reporting: You want to show when the parent of each work item was created, for tracking or reporting purposes.

  • Custom fields: You need a custom field in Jira that automatically displays the creation date of the parent for each work item.

  • Filtering: You want to filter or sort work items based on the creation date of their parent.
