Instead of taking the approach above, let's do this:
define_tag 'parent' do |tag|
parent = tag.locals.page.parent
tag.locals.page = parent
tag.expand unless parent.nil?
end
This way the tag will not be rendered if the parent doesn't exist. The
above also makes the tag context sensitive (so you can use it inside a
children:each tag).
We should also add the if_parent and unless_parent tags:
define_tag 'if_parent' do |tag|
tag.expand unless tag.locals.page.parent.nil?
end
define_tag 'unless_parent' do |tag|
tag.expand if tag.locals.parent.nil?
end
If someone can get me a unit tested patch for this I'll apply it.
