Custom Functions for Projects

Automate your project workflow using Custom Functions.  A custom function is a software code that can be used to automate a process. In Deluge, you can write your own function and call it from one or more  Workflow rules. It is similar to Javascript's built-in functions such as DATE, CONCAT, REPLACE, and so on. Custom functions allow you to automate a notification, call a webhook, or perform logic immediately after a workflow rule is triggered.
For e.g., a custom function can be used to archive a project whose status is marked as complete. To do so, you will need to write a custom function as shown in the image below and save it.
This custom function is then associated with a workflow rule. Select the Update as the option for the Execute On criteria in the Workflow. Set the criteria in the condition as Project Status is Completed and save the rule.
Now, when a projects status is changed to Completed, the workflow rule will trigger the custom function and archive the project automatically.
