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
