I'd recommend Agile Web Development with Rails (Pragmatic Programmers book).
I looked online but couldn't see a lot that was easy to learn from.
Basically a helper method is a method that is available in your views and
(can be) used for generating markup that would be repetitive otherwise.
For example you could have something this:
application_helper.rb:
module ApplicationHelper
def christophe_link_action(image_filename)
link_to_remote (image_tag(image_filename, :size=>"16x16"),
:url=>"/message/#{message.id
}/hide",
:method=>"post",
:before=>"Effect.Fade(this.parentNode.parentNode, {duration:
0.5});
Effect.BlindUp(this.parentNode.parentNode, {duration: 0.5})")
end
end
Then in your view just do:
<%= christophe_link_action("foo.png") %>
<%= christophe_link_action("bar.png") %>
Does that make things any clearer? If not, I'd recommend the book I
mentioned earlier (or post back with questions).
Cheers,
Andy
