Rails - Sep 2006 - Where to put a function called by a model?

I''m using a slight modification of the simple_date_select plugin to 
display and accept input for dates in m/d/yyyy format. But this doesn''t
handle the view of dates when they are not being edited.

Being new to Ruby and Rails I couldn''t figure out how to create a 
similar simple_date_view plugin. And it seems too much to ask that 
someone else create one! So the next best thing is to at least create a 
function that my models can call for each date field. I tried putting 
this function in controllers/application.rb but nothing seems to happen, 
not even an error message. So I suspect that functions in that location 
are not available to models. So where would I put my little 
date-conversion function?

By the way, I can get the code to work if it''s in the model itself, but
I want to have a global function so I don''t have to repeat the code for
each field.

Thanks,
Shauna

Shauna,

Any classes/modules you add to your app/model or lib directories are  
accessible from any of your models (and your controllers and views).   
So you could add a class like this:

Class DateToolbox
   def self.convert_date(d)
     ...
   end
end

Then from any model you can call DateToolbox.convert_date.

A slightly more complicated but cleaner approach would be to override  
or augment the simple_date_select plugin with your conversion  
routine.  Here is a simple example of adding a method to Ruby''s built- 
in String class:

class String
   def hello
     "hello #{self.to_s}"
   end
end

"aaron".hello  =>  hello aaron
