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

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?

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”.

.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.

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.

eg.
In Helper:
def not_for_customer
yield
end

In View:

‘our_ref’ is not rendered…
