I'd vote for this method over setting the context,
since one of the goals of a model is to not care about
how or when it's called, that way you are encouraging
yourself to not build a fragile application where
everything is interdependent.  Actually I'd take it a
step further and only pass the stuff from the context
that you need, like $c->request if you need the
request object, etc.

That being said I have used the method suggested by
another responder for grabbing the context, mostly so
that I can do debugging inside the model
($c->log->...).  If there was better way to access the
log object from views and models that don't require
getting the context or getting $c->log than I am sure
I'd never need it.

A seemless way to share $c->log with DBIx::Class
objects would also be nice.

Also, as an aside, if you are building a custom logger
it might be more fun to create your own logger object
so that you can do $c->log->mylogger(...), or I
believe you can use the Log4Perl catalyst plugin and
configure it to log to a databse.  That way you can
skip the whole creating a custom model for this need.
