FAQ
hi,

I tried to install an old CRUD Catalyst example (Rockway's AddressBook app,
detailed in chapter 3 from his PACKT book) and I got errors. I've fully
fonctional examples (from the Definitive Guide), like SneayCat - thank you,
it's an excellent one ! - on the same machine, a CentOS 5.5 config with Perl
5.8.8, Catalyst 5.80024 and modules, among them :

Catalyst::Devel is up to date (1.28)
DBIx::Class is up to date (0.08123).
Catalyst::Model::DBIC::Schema is up to date (0.43)
Catalyst::Devel is up to date (1.28).
Catalyst::Plugin::Authentication is up to date (0.10016).
Catalyst::Plugin::Authorization::Roles is up to date (0.08).
Catalyst::Plugin::ConfigLoader is up to date (0.28).
Catalyst::Plugin::Session is up to date (0.30).
Catalyst::Plugin::Session::State::Cookie is up to date (0.17).
Catalyst::Plugin::Session::Store::FastMmap is up to date (0.13).
Catalyst::Plugin::StackTrace is up to date (0.11).
Catalyst::Plugin::Static::Simple is up to date (0.29).
Class::MOP is up to date (1.04)
I applied changes detailed here (*AddressBook::Schema::AddressDB::Result*):
http://wiki.catalystframework.org/wiki/thebookerrata
http://lists.scsys.co.uk/pipermail/catalyst/2009-April/021929.html

It doesn't work for me and i'm lost : I don't understand why the
component can't be instantiated. Is something missing ?
Thank you in advance for your help !

    Something IS missing - the 'Addresses.pm' module! Actually, I'd be
    surprised if it's actually missing, however Perl can't find it for some
    reason. I would check the 'package' declaration in your module against
    the error. It could be an issue with plurality, likely because a change
    was made somewhere along the line in how DBIC handles this. Whatever
    the case, perl is looking for that module and can't find it.

    Thanks you for your answer.
    But you're right, the module ..is in its directory. I'm going to check the
    package declaration.

    I wondered if my team (a java one) could use Catalyst in a production env,
    but we're not ready. A lot of examples don't work (from the first and the
    second books we bought). I discovered the last erratas on the apress site :
    is it possible to get a full (+edit) DBAuth example that works ? It would be
    nice to remove, for "simple" CRUD examples, the authentication layer and get
    working code with *stable* conventions, at least for new comers like us ! It
    is *very* difficult to start Catalyst Tutorials from cpan on other distribs
    (Debian is ok, but we don't use it here). Catalyst is an elegant one, but
    hard to master (?!).

    Best regards,
    marc

    Something IS missing - the 'Addresses.pm' module! Actually, I'd be
    surprised if it's actually missing, however Perl can't find it for some
    reason. I would check the 'package' declaration in your module against the
    error. It could be an issue with plurality, likely because a change was
    made somewhere along the line in how DBIC handles this. Whatever the case,
    perl is looking for that module and can't find it.

    It doesn't work for me and i'm lost : I don't understand why the component

    But you're right, the module ..is in its directory. I'm going to check
    the package declaration.
    I wondered if my team (a java one) could use Catalyst in a production
    env, but we're not ready. A lot of examples don't work (from the first
    and the second books we bought). I discovered the last erratas on the
    apress site : is it possible to get a full (+edit) DBAuth example that
    works ? It would be nice to remove, for "simple" CRUD examples, the
    authentication layer and get working code with *stable* conventions,
    at least for new comers like us ! It is *very* difficult to start
    Catalyst Tutorials from cpan on other distribs (Debian is ok, but we
    don't use it here). Catalyst is an elegant one, but hard to master (?!).
    Being a new comer to Catalyst myself, I've had similar experiences. I
    will say that we were all warned that the learning curve was substantial
    (I'm referring to the Definitive Guide to Catalyst). Over the past year
    I have had to put off things that I *wanted* to do because I didn't
    quite understand enough about the underlying code. Tools like
    HTML::FormHandler have several features that I think would be cool to
    use (Widgets), but I've had enough just getting basic database updates
    to work that I can't possibly spend the time now learning how to make
    HFH output HTML (I'm sticking with template toolkit).

    I will say that I've learned a lot about Catalyst, and feel like I've
    just scratched the surface. We do have a very simple production
    application written in Catalyst, and are working on a much more complex
    one currently, as we are believers in the perl community and CPAN and
    the philosophies associated with them.

    Good luck, and keep at it!

    Something IS missing - the 'Addresses.pm' module! Actually, I'd
    be surprised if it's actually missing, however Perl can't find it
    for some reason. I would check the 'package' declaration in your
    module against the error. It could be an issue with plurality,
    likely because a change was made somewhere along the line in how
    DBIC handles this. Whatever the case, perl is looking for that
    module and can't find it.

    Similar experience here -- Catalyst pulls in so many modules, it's difficult
    to see which method, from which module, is the one that's Just Right for the
    task at hand. This is the strong point of modular code, of course: just
    refer to a module someone else has already written that takes care of this
    issue, leverage their experience and brainpower, and you save yourself a lot
    of time.

    But there's still a steep investment finding the right method from the right
    module. There are so many!

    It's a difficult problem and I don't think there will be any great solution
    any time soon. Google helps, places like CPAN help, folks who blog about
    their trials and tribulations and solutions can help, but a definitive "how
    to do my very specific task X" is often difficult to find without disturbing
    folks on-list. (I'm imagining a Carnegie grant to get something going... :)
    There's still a learning curve, but the corve has moved -- from "how do I do
    this in Perl" to "How do I leverage the experience of all these bright folks
    who have gone before me?"

    But even for all its complexity and power, Catalyst really is well
    documented, the community is great, and putting working websites together
    really does get more and more elegant, the more you learn about the
    framework. I was coding for a bit with a hardware wonk watching over my
    shoulder and he saw me add two lines of code that did tons of work, adding
    loads of functionality, and he was just floored. Getting to the point where
    you know which two lines of code to add, that's the trick. :)

    a hammer?"
    "No, the hammer-hit only costs $1. Knowing WHERE to hit the engine, *that*
    costs $499."
