haml is installed as a plugin and *.haml files render correctly. rails
version is 2.2.2
i have this in my application helper and would like to convert the
concat("<ul>") and concat("<li>") to work nicely with haml. i have
tried "open", "haml_concat", and "haml_tag". i couldn't get anything
to work, they all raised errors probably because i couldn't figure out
the correct syntax or something. anyone have any suggestions?
def display_tree(tree, parent_id=nil, &block)
concat("<ul>")
tree.each do |node|
if node.parent_id == parent_id
concat("<li>")
yield node
display_tree(tree, node.id) { |n| yield n } unless
node.children.empty?
concat("</li>")
end
end
concat("</ul>")
end
