Re: coding practices with models

I use the model class as the maintainer of the individual record and
the provider of a collection of records.

So in your banana example, my model would know what to do when a
controller stated that peeling the banana was required :)

Whether or not to read the banana into the model depends on the
situation you are in - is the banana currently being viewed, then the
model already has the banana - but if the banana was just one of many
selected by the user for peeling, then the model would need to be
provided with the id of the banana to peel, read it from the database
and then peel it :)

I would not let the controller know whether to read the banana in the
model, that is the models responsibility, to ensure that the correct
banana is being peeled :) - so the controller would just provide the
id to the model through the peel method and the model compares whether
the current banana is the requested one!

I usually separate the model methods into those that works with an
individual record and those that work with a collection of records.
