Rails - Apr 2005 - Newbie questions on models/controllers/helpers

Hi -- New to ruby/rails, have a couple of organization questions:

1) Can I call a helper from the model? Any special syntax for that? (I 
tried a couple of things, none seemed to work.)

2) In general terms, the app I''m working on: Retrieves data from the 
db, formats it, displays it to the user. The user may make some 
modifications, which are then applied to the data (but *not* sent back 
to the db) and the resulting data+modifications are displayed to the 
user. I guess I''m having trouble with the split between oo code and 
m/v/c code: Where does the "make the modifications" code go? Part of
me
thinks this is object modifying stuff, which sounds like model, but 
it''s dealing with user input to the Webapp, so that''s
controller... er?


Thanks for your help with these questions. (I''m sure I''ll have
more.)

For 1) add helper_method :method_name just after the method in your
controller to make it available to the views.

For 2) http://www.slash7.com/flashback/2005/02/mvc_the_most_ve.html#more
could help. If you''re not modifying the data stored in the database, I
wouldn''t involve the models. Seems strange to have data modification
that isn''t persisted to the db, but then I don''t know your
app! :)

Cheers,

Chris
