Hi Sean,

You could put something like this in you application helper; based on the condition, it will wrap what's in the block with your anchor tags. The key is concating something to the block binding.

def link_if(condition, &proc)   if condition     start_anchor = '<a href="#" onclick="Effect.toggle('edit_project_name', 'appear', {duration: .5}); return false;">'     end_anchor = '</a>'     concat(start_anchor, proc.binding)     yield     concat(end_anchor, proc.binding)   else     yield   end end

Then in your view you'd put this:

<% link_if @isopen do %>   Project name: <% end %>

That's a lot cleaner.

Or put something a lot more general in your helper:

# descended from the union of link_to_unless and link_to_function

Jim,

You should try to take a look at the "Show Source" in the Rails RDocs. While it can sometimes seem like you're falling down a rabbit-hole as little 3-5 line methods call other methods which call still others, you can open up the source file and browse through it. Most of the code is quite well written and it's a great way to learn more about Ruby.
