All,
I have a page X, which has several children pages underneath it (say,
10).
Is there any relatively easy way to derive the index of a given child
of X in the list of children of X? So, for example, for the 3rd
child, I need to be able to get a 3 somehow in order to construct links.
I'm displaying children using r:pagination and I'm generating
direct links to the children. I'd like these direct links to reflect
the pagination within the context of the parent.
So, for example, I want a link to the 3rd page of X that looks just
like the link I get from paginating X, which is: /x/?page=3
I tried just forcing the slugs to be these types of links, but get a
bad format error when I try to save the page.
This doesn't seem like it would be that hard to add a tag that
derives a child's location within it's set of siblings underneath a
parent, if I had to.
Many thanks,
Wes
I've created a custom tag named child_position for this, and I'm
very close to getting it working. Here's the tag definition - this
is, of course, executed within the context of a r:children:each tag:
tag child_position do |tag|
if parent = tag.locals.page.parent
parent.children.index(tag.locals.page)
end
end
but nothing gets output. I've verified that the parent object is a
page, that it has children, and that tag.locals.page is a page.
What am I doing wrong?
Thanks,
Wes
My bad - this works fine. There is some caching going on in my
development platform, either from Firefox (notorious for it, I know)
and/or Radiant. I refreshed my page this morning and I see that this is
working.
Awesome. Integrating new Radiant tags seems really straightforward.
I'll fork the base and send a pull request to include
r:child_position/ as a core tag.
