[Rails] Best way to organize non-controller logic???

I don''t want to put certain code in my controller because I think it 
makes things more confusing.

What is the best way to manage business logic such that it doesn''t end 
up in the controller?

Basically, where should I put my regular utility classes and backing 
objects that may not be models?

Thanks,
Wes

application.rb can be a good spot for general purpose stuff - I put
e.g. my date formatting stuff in there to ensure dates are shown
consistently across an entire site.

you could create modules and put them in the lib directory.

Can you give an example of business logic that doesn''t interact with a
model?

[Rails] Best way to organize non-controller logic???

for me, I have to access external information on an AS/400 system.  My only
access to the system is via ODBC, for which there is no AR Adapter
avaliable.

so what i did was create a module for making connections to and extracting
information from the AS/400 and put it in the lib directory.

AS400.rb

require ''dbi''
module AS400
  def AS400.get_some_data(args)
    # do the AS/400 stuff here
    # massage the data if needed (strip whitespaces, do some calculations,
etc)
    return data
  end
end

then where i need it, typically a controller, i just require
''AS400'' and do
AS400.get_some_data(12345) .

[Rails] Best way to organize non-controller logic???

Personally, I''d say that looks like a model.  You can just put it in
your models directory, and use it from controllers the way you
normally would.  You''ll need to set up some mocks in order to unit
test it, since most back-end systems like that don''t provide usable
test regions. (At least not for the meaning of the word that OO
programmers are comfortable with.)

You can use the "model" and "service" controller class
methods to make
sure it gets ''required'' in the appropriate place.

It''s  cleaner BUT it''s cached in development mode => if you
change it,
you need to restart the server.

[Rails] Re: Best way to organize non-controller logic???

I have a filename that is an attribute of one of my model objects.  It 
references a file in the file system.

I need to figure out if that file is an Excel file, a CSV file, or 
neither.
