Hey guys,
There is something I have been trying to implement but so far no luck.
Basically, I want to have helpers that generate HTML around given
content, similar to ActionView''s form_for. Besides, I want to keep
that "framing" HTML in separate files, similar to templates.
Ideally I''d even love to suggest it as a feature for Rails. Let me
show you an example.
This is what I want to have in my rhtml file:
<% bubble_block :corners => "round", :color =>
"brown" do %>
<div id="content">My content</div>
<% end %>
So far I have tried the following: I added a method to my application
helper:
def bubble_block(options, &proc)
raise ArgumentError, "No block given" unless block_given?
rendered_html = render(:partial => "/templates/bubble", :locals
=>
{:block => proc} )
concat rendered_html, proc.binding
end
This is how _bubble.rhtml looks like:
<div id="bubble">
<% block.call %>
</div>
What happens is *ALMOST* what I want, except my block gets rendered
twice. The output looks like this:
<div id="content">My content</div>
<div id="bubble">
<div id="content">My content</div>
</div>
What am I missing? Thank you!

Thank you!Since you don''t say what options is supposed to do, perhaps this give you an idea of how to proceed: def bubble_block options={}, &block raise ArgumentError, "No block given" unless block_given? content_tag :div, {:id => ''bubble''}.merge(options), &block end and forget about the unnecessary _bubble.rhtml -Rob Rob Biedenharn http://agileconsultingllc.com Rob-xa9cJyRlE0mWcWVYNo9pwxS2lgjeYSpx@public.gmane.org --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Thank you for replying, Rob. I already know how to do it without external .rhtml (I can use concat() inside of bubble_for). However, the entire idea is about using external .rhtml files for surrounding HTML, since there is a lot of HTML and having that HTML embedded into ruby code is not practical (designers need to touch it). What exactly in my implementation causes the wrapped block to render twice? Inside and outside of the surrounding HTML?
