Form_helpers?

Rails

Just a quick silly question , are form_helpers actually helper.rb files
?

If you mean are they in ruby source then yeah. You can have a look at
the source in somewhere like:
/usr/local/lib/ruby/gems/1.8/gems/actionpack-1.12.3/lib/action_view/helpers/
(depending on your install).

You should find all of the code for rails in the gems folders - great
place to look to understand how it all works.

I’m sorry, Im reading about them in AWDWR and have started to read
through the API docs. What I wanted to know is the code part of the
helper files -> app\helpers or part of the .rhtml pages ?

Oh - helpers are in app/helpers and are ruby methods. AWDWR should
cover all that in depth.

:), so form_helpers are part of the code that goes into the app\helpers
files ?

I’m not sure what you mean by form_helpers - are you talking about the
rails form helpers like ‘text_field’ or ‘submit_tag’?

View helpers are defined in app/helpers. So you can write methods that
will be accessible in your views:

– app/helpers/pages_helper.rb
module PagesHelper
def say(message)
message
end
end

– app/views/pages/index.rhtml
<%= say ‘Hello!’ %>

This would display:

Hello!

Hope that helps,

These are the ones I’m speaking about . Yes the text_field, etc.

I gather they are not part of the code that goes into helper files.

Sorry - i may still be a bit confused about what you mean :0)

The code for text_field and the like are effectively the same as code
you’d put into app/helpers when you write your own helper files. You
can view that code yourself as i mentioned in my previous post.
