Template:Shelf:Ancestry/doc
 | This is a documentation subpage for Template:Shelf:Ancestry It contains usage information, categories and other content that is not part of the original template page. |
Usage[edit source]
Use this template on the ancestry page of a shelf in the Wikibooks Stacks; anything on the ancestry page other than the template call should be noincluded.
The name of the ancestry page is formed by appending suffix "/ancestry" to the name of the shelf page, thus Category:Shelf:shelf/ancestry.
One parameter is required:
ancestors— a wikilisp-formatted list of all ancestors of the shelf.
The ancestor relation is the closure of the parent relation supported by the shelf pages (see {{Shelf:Page}}). As with parents, ancestors may be shelves or departments.
When called with non-blank first unnamed parameter (with value other than ping), or when viewed from a non-ancestry page, this template provides its ancestors list, or, if the first unnamed parameter has value ping is non-blank, the template returns the pagename of the template itself, Template:Shelf:Ancestry. If viewed from an ancestry page (without overriding parameter), this template checks for problems with the associated shelf page and, if found, displays a notice explaining the problem and suggesting how to fix it, with buttons to perform likely remedial actions.
Internals[edit source]
This template itself determines which sort of information request is being made, and either provides information directly, or delegates the display function to {{Template:Shelf:Ancestry/display}}.
