Alias mod

Enable Alias cards, which alias one simple card name to another.

The primary use case for alias cards is for handling redirects, for example after a card has been renamed. Suppose, for example, a card's name is changed from Former to Current. One can create an Alias card named "Former" with the content "Current". This not only insures that links to /Former will be redirected to /Current, but it also handles all descendants, redirecting /Former+field to /Current+field and /My+Former+Life to /My+Current+Life.

Alias cards themselves must be simple cards and are not allowed to have children.

If a request to an alias specifies a view, eg /Former?view=edit, then the request will not be redirected and will instead return the view of the Alias card itself. Similarly, transactional requests (create, update, and delete) to the alias card will take effect on the alias, not the target.

Sets with code rules

type: Alias

An alias card's name is the alias's source, and its content is its target. So, in the example above, the Alias card would be named Former and its content would be Current.

Content is stored as a card id.
