This is something I cooked up today, because of a project I've been working on.
I'm always having to struggle a little bit to get my helpers
generating decent xhtml. Helpers are the next big thing that we have
to figure out as a community. That is, to answer the question, how can
I build really compelling views with some nice programatic logic that
is modularized into the helpers.
Well, here is a step foreward. Its something like content_tag, except
mixes in some Haml magic.
I wanted to have this in my view.
- info_table do
- row :price do
Price (in CAN dollars)
- row :name do
Name of the product
The reason I'm using blocks is because I really wanted to be able to
easily drop in programmatic things (like hidden fields, javascript
bits, and etc) into the page without having to concern myself with
doing it repeatedly. I don't know if this makes sense, but each row
would actually automatically generate the form elements needed for
that row. The block area just serves as a label-generator.
Let's see how we'd implement this with open_tag
def info_table(&block)
open_tag :table, &block
end
def row(named, &block)
open_tag :tr do
open_tag :td do
block.call
end
open_tag :td do
push_text form.text_field(named)
open_tag :div, :class => "errors" do
error_messages_on :project, named
end
end
end
end
So much automatic goodness built right in! And its not even ugly!
Thoughts?

PS: open_tag most likely has a bevy of bugs, so please.... report
away! I wrote it in 5 minutes.
