Hi t0m:
Pretend I'm a complete ignoramus... (that shouldn't be too hard, LOL)
If I were to want to submit a "doc patch", how would I go about doing it
and what exactly would I be submitting?
One revelation I had recently which I don't think has been mentioned
anywhere (at least not that I recall) is that when using DBIC and
Catalyst, *everything* is treated as a scalar. (is this a true
statement?) So in other words,
my $people = $c->model('AddressDB::People')
instead of
my @people = $c->model('AddressDB::People')
This hit me while reading p. 41 of the book. I'm not even totally sure
it's correct but things seem to work better when I adopt this
view-point, so it probably is correct. It kind of makes sense, because
the Catalyst stash stores things using scalars (strings) as keys, so if
you just think of everything as a scalar (which could be a ref to an
array or hash) then things become slightly less confusing. At least,
that's my current understanding. I am still very much muddling my way
through all this stuff.
What I haven't figured out (yet) is why it is necessary for me to cast
some things to array, whereas other times it works without casting to
array. I'm sorry, I don't have a specific code example. I'm still
working through the book and studying CPAN documentation pages
furiously. I'll get it eventually.
