/*
|
|
* ITFlow - links between documents, files and what they are about, the
|
|
* devices, users, credentials and files on a license, the documents and
|
|
* files about a location, and what a service depends on.
|
|
*
|
|
* One handler for every pair LINK_RELATIONS knows (functions/links.php):
|
|
* link_items links any number of records at once, unlink_item drops one.
|
|
* The older one-pair-each names (link_asset_to_document, unlink_contact_from_file
|
|
* and so on) are still answered here, so a link built by any page or older
|
|
* modal keeps working - and gets the same checks: the same client, nothing
|
|
* archived, no 500 on a link that already exists.
