Modules	Replace existing link when a link that uses a different link type is added to the same issue (on-change rule)

Use Case

This workflow prevents you from having two different link types for the same issue, which can create a conflict in your process.

Modules

This on-change rule checks the list of linked issues for a link to an issue that is added as a link when the issue is updated. If the new link is duplicated by a link to the same issue with a different link type, the link is replaced with the link specified in the update.

Replace existing link when a link that uses a different link type is added to the same issue

        const entities = require('@jetbrains/youtrack-scripting-api/entities');

        function hasAddedLinks(links) {
          return links && links.added && links.added.isNotEmpty();
        }

        exports.rule = entities.Issue.onChange({
          title: 'Replace existing link when a link that uses a different link type is added to the same issue',
          action: (ctx) => {
            const issue = ctx.issue;

            const relatesTo = issue.links['relates to'];

            const duplicates = issue.links.duplicates;
            const isDuplicated = issue.links['is duplicated by'];

            const dependsOn = issue.links['depends on'];
            const isRequiredFor = issue.links['is required for'];

            const subtasks = issue.links['subtask of'];
            const parent = issue.links['parent for'];

            const allLinks = [duplicates, isDuplicated, relatesTo, dependsOn, subtasks, isRequiredFor, parent];

            function cleanup(target) {
              if (hasAddedLinks(target)) {
                target.forEach(function(issue) {
                  allLinks.filter(function(link) {
                    return link && link !== target;
                  }).forEach(function(links) {
                    links.delete(issue);
                  });
                });
              }
            }

            if (hasAddedLinks(duplicates) || hasAddedLinks(relatesTo) || hasAddedLinks(dependsOn) || hasAddedLinks(subtasks)) {
              cleanup(duplicates);
              cleanup(relatesTo);
              cleanup(subtasks);
              cleanup(dependsOn);
            }
          }
        });
