Access one specific child

Hi,

is there a way to select one specific child, in contrast to iterating
over all of them?
Something like <children:each slug=“child-slug”> or .

thanks

I have made a little patch for that to find a URL locally relative to
the current page:

— standard_tags.rb (revision 363)
+++ standard_tags.rb (working copy)
@@ -396,9 +398,12 @@
}
tag ‘find’ do |tag|
if url = tag.attr[‘url’]

  •  if found = Page.find_by_url(tag.attr['url'])

  •  if url[0..0] != "/" and found = Content.find(:first, :conditions

=> [“slug = ? AND parent_id = ?”, url, tag.locals.page.id])
tag.locals.page = found
tag.expand

  •  elsif found = Page.find_by_url(tag.attr['url'])

  •    tag.locals.page = found

  •    tag.expand
  end
else
  raise TagError.new("`find' tag must contain `url' attribute")

You just use it like find: <r:find url=“slug”>…</r:find>

Cheers,
Oliver

Exactly what I needed!

Will this patch be applied to the svn repo?

Thanks

Hi Oliver,

Perhaps this should be added to Radiant’s Trac.
I would welcome this patch as well.

Regards,
Erik.
