About space prefix
Each Assembla space has a unique name and prefix. The space prefix unique code identifies the space and becomes the first part of ticket numbers, for example, BR-1, BR2. We automatically generate a prefix on space creation, but you can edit it manually, and it appears together with the ticket ID.
You can use space prefix to:
Add links to tickets in other spaces by using #PREFIX-TICKET_ID markdown. For example to add a link to ticket '#4' from 'My Awesome Project' (MAP) simply type
#MAP-4in the comment or description content.
Create relations between tickets in the different spaces by searching by prefix name.
Use new alias to the ticket details link. Currently, link to a ticket includes space name in it ex: https://PORTFOLIO-NAME.assembla.com/spaces/SPACENAME/tickets/23
Prefix allows using a direct alias without space name like:
https://PORTFOLIO-NAME.assembla.com/tickets/PREFIX-4
API
Project prefix can also be used in API calls, so you do not need to pass the space-name parameter if using a ticket ID with a prefix. Read more in the API Documentation.
Hide Space Prefix
You can hide the space prefix functionality if you want. Just navigate to your Portfolio Admin Settings > Toggle Tabs and Features Visibility section, and simply un-check: 'Space prefixes: if enabled, an unique space prefix will be shown in ticket views' option.
