You’re my savior Josh. I had been messing around with helpers methods, and didn’t like the result.

Your technique is much more elegant and certainly more readable and updatable.

You rock !

[...] This may be the most subtle change I’ve ever been this excited about. Let’s go back to the bad old days — last week — and say that you wanted to write a block helper method like this: [...]

sorry, the view code was sanitized …

in view:
ajax_call(params) do
a_method_to_be_called(with_params)
end

Very interesting!

These techniques opens up many possibilities, some even very strange:

in view:

a_method_to_be_called(with_params)

the ajax_call in the helper:
concat(
link_to_remote(“Add”, :url=> {:controller => …, :action => …, :block => capture(&block)}
), block.binding)

This means we can pass to controllers functions to be executed, functions defined freely in views.

Does this sound weird for you?

Thanks for the advice, really helpfull. I prefer use the rails default (prototype and scriptaculous )and how good will be if prototype add corner method to your features.

There are a couple of errors in the code samples in the “Here’s an example of the rounded_corner code I actually use in my applications” part of this post.

First, the “rounded_yellow_box” call needs a “do” at the end of it.

And “if options[:background]” needs to be followed by a “then”.

Choosing a different template engine might improve readability and reusability even further. I use haml and jquery, and all I do is:

.corner Rounded corners are so Web 2.0.

and in application.js:

$(‘.corner’).corner();

and in css e.g.:

.corner { background:#ffe; border:1px solid #999; }

Can’t get easier then this.

Well-written article and your code really pushes deep into rails helpers. Well done!

Unfortunately, readers should be cautious of injecting HTML syntax directly into helper methods in ruby. Typically, the larger the project, the faster the HTML changes. And if your designers aren’t familiar with ruby, then change becomes hard.

Good points. Much of this was discussed before, but reminders are always good.
