Subtask inherits parent task values

When creating a subtask in Redmine you may want it to automatically inherit certain values from the parent task. Here I will explain step by step how to achieve this.

What details to inherit

Let's assume we want the child task to inherit

• subject
• description
• version

from the parent task.

Install View customize plugin

If you follow these Redmine Pills you have already noticed that I use View customize plugin for many purposes. This is one of my favourite Redmine plugins. It is my Swiss Army knife 😉

Create a new View

Go to Administration > View customize and create a “New view customize” as follows:

Path pattern: .*

Project pattern: include project identifier in case you only want this code to apply to a certain project

Insertion position: Bottom of issue detail

Type: Javascript

Code (copy/paste):

	
$(function() {
  var addLink = $('#issue_tree a[href*="/issues/new"]')[0]; 
  var subject = $('#issue_subject').val();
  if (subject) {
    addLink.href += '&issue%5Bsubject%5D=' + encodeURIComponent(subject);
  }
  var description = $('#issue_description').val();
  if (subject) {
    addLink.href += '&issue%5Bdescription%5D=' + encodeURIComponent(description);
  }
  var version = $('#issue_fixed_version_id').val();
  if (version) {
    addLink.href += '&issue%5Bfixed_version_id%5D=' + version;
  }
})
