[Catalyst] Program the logic
Hello all, I'm planning to program the logic of the application (the Model in MVC) previously to start with web page and the presentation. What is the best way to do it? (some philosophical remarks :)) What I see is that what Catalyst calls Model is just the Objects that map with the tables in the DDBB. And the logic of the application are developed in the Actions (in fact linked to the web application). I know is difficult in practice to separate both worlds (logic from the presentation) but that is the false promise of the MVC pattern :). Anyway, the question is just what is the best practice to program the logic and test it before link the logic with the web application?. (using the classes generated by the Class::DBI or whatever plugin).

[Catalyst] HTTP::Body(::MultiPart) RFC md5 digests for uploads
Hello ,
Having used Catalyst for the last few months I was presented with a challenge;
make Catalyst generate an MD5 sum for each uploaded file in a request, for
files of (almost) arbitary length. Since MD5 summing a 640mb .iso is rather
time consuming, it makes sense to calculate the sum on the fly as the
incoming request is being processed.
It took me some time to track down the fact that HTTP::Body::MultiPart was
responsible for the writing of request data chunks to temporary files.
Attached is a first try at this which includes
patch HTTP::Body::Multipart to create a Digest::MD5 object and -add chunks
of incoming data to it.
patch Catalyst::Request::Upload to add and accessor for 'md5'
patch Catalyst::Engine::prepare_uploads to take the upload object(s) from
request-{_body}-upload and create Catalyst::Request::Upload object
including the 'md5' attribute.
I welcome comments about the sense and usefullness of this :)

Re: [Catalyst] Program the logic
I'm not 100% sure I understand your question, but there are a couple of ways to
call actions or methods associated with a Controller. Here are the ways I've
found to programmatically call a catalyst action from within my logic, but of
course the whole things gets started off with a http request to something:
First, you can use the $c-forward() method. Using this allows you to forward
to an action is has the bonus of passing $c for you automatically.
You can also use
$c-controller('Foo')-do_stuff; method. I'm so so familar with this one as I
usually don't need it. I'm sure one of the other experts can fill in why this
is useful.
Also you can just 'plain vanilla' methods in your controller class and
reference them with $self-method(). This is good when you want to encapsulate
functionality without creating an action and poluting the action list
needlessly. You might have:
sub some_form : Public {
my ($self, $c) = @_;
if( $self-validate_these($c-request-parameters()) { .}
}
sub validate_these
{
my $parameters = shift @_;
#run some validation
}
This can be really useful if you are subclassing Controller to make your own
and want to encapsulate functionality. Remember, you don't need to make every
single method in your controller an action!
There is a $c-detach method which is similar to forwarding but doesn't return
to the caller.
You can also use the subrequest plugin to call an action. That is a lot like
forwarding but it creates a totally new catalyst request. I've used this when
trying to mimic a portal where the main page calls a bunch of URIs to assemble
itself.
If you want to call a catalyst action from outside the catalyst framework, I've
used LWP to call URIs from things like cron jobs, etc. I don't know if there
is a way to access catalyst any other way.
I think that covers the ways and whys I've found with controller actions. Good
Luck! --john

Re: [Catalyst] Program the logic
Thanks for your long answer.
When you create a Catalyst application some tests are created also.
I thought calling the Controller actions could be performed by the
testing framework... (without using a browser)...
I guess I was wrong :)

If you've at least tried running those test you'd have seen it. Also, if you were really up to it, you could write something like a Catalyst::Engine::Tk and have and have a somewhat weird URI-based Tk handling (i.e. each of your widgets actions would be described by an URI).

I worked through the dialog, it really wasn't a problem, just not what I wanted to do with my boss breathing down my neck regarding my choice of Catalyst as an application platform. The thing about using the CPAN shell is that you're able to use more modules and you'll usually have newer versions of the modules. You'll be able to see that some modules have optional dependencies and choose wether to install them or not (PPM doesn't follow optional dependencies). Of course it takes a little bit longer when installing through the CPAN shell because it actually runs the test cases on your machines so you're even safer when using it (it's perfectly possible that a module worked alright at ActiveState's server but doesn't work correctly on your machine due to various circumstances). I think you were a little bit frightened probably because it installed *a lot* a modules. This probablu happened because, since you previously only used PPM, you had a lot of outdates modules and when installing Bundle::* from the CPAN it installs everything in that bundle unless you've got the newest version. When installing normal modules it will only install a newer version if it's a module requirement. After installing some heavy-weight modules such as Task::Catalyst, DBIx::Class, Bundle::CPAN, PAR and POE most of your installs will end up being single module installs since you'll already have most of the usual dependencies installed. BTW, Why is it Task::Catalyst and not Bundle::Catalyst? I want to install this but it does not run, getting an NMAKE fatal error U1077, errors looking for GPG, etc. This is why I like the PPM packages...

Although it's somewhat like killing a mosquito using a shotgun, I usually install the Dev-Cpp open-source IDE for Windows. It already comes with everything you need to self-compile your modules (GCC/MinGW, etc) and works out-of-the-box. It's not a big download (8mb I think) so it's something pretty reasonable. The only manual configuration I remeber having to do is to add the GCC /bin dir to my system PATH variable. And then the CPAN shell from ActiveState will automatically configure itself and work using GCC. Since you've upgraded your CPAN shell using a version from the CPAN, I don't know if the magic still works and you might have to manually configure your compiler parameters (but that's a one time thing). -Nilson Santos F.

my @numtextCaps = (Zero, One, Two, Three, Four,
Five, Six, Seven, Eight);
$c-stash-{numarray} = @numtextCaps;
in .tt file:
[% FOREACH word = numarray %]
h3[% word %]/h3
[% END %]
The loop only iterates once, and prints out:
9
at that one iteration.
My code seems to match the way the foreach loop is done in the
Template Toolkit documentation, so I must be missing something in the
way TT interacts with Catalyst?
$c-stash-{numarray} = [EMAIL PROTECTED];
As we said on the DBIC list, read perldoc perlreftut and perlref for full info
about how all this works.

Re: [Catalyst] [announce] Catalyst 5.70 developer release.
Please be consistent with the number of digits in the versioning scheme. While it may be easy for humans to guess that 5.7001 comes before 5.80, packaging tools like RPM and APT could easily get confused. While such problems could be worked around by using tricks like epoch numbers, it would be best to avoid the headache altogether with a sane versioning scheme.

This is indeed the point of the discourse below, although some of it may have been left out as I've previously convinced Matt on irc. (FreeBSD ports will indeed complain loudly about 5.6902 - 5.70, and I don't have the physique for jumping through hoops.)

I am changing in debian package to 'normal' version scheme. But then debian/watch doesn't work. But this is really minor problem. Define normal ? for example: first 5.6902, then 5.70_1 then 5.70. From debian point of view 5.70 is before 5.6902, 5.70_1 is invalid (so probably should be changed to 5.70.01 but then it's after 5.70 so probably should be changed into 5.69-5.70pre1 etc.). But this is minor problem, it's only make automatic tools blind but always can be changed manualy. The next production release will be 5.7000 - what's the problem with that? But will be tar.gz named Catalyst-Runtime-5.70.tar.gz or Catalyst-Runtime-5.7000.tar.gz? It makes difference with automatic upgradind tools. eloy -- [EMAIL PROTECTED] jak to dobrze, że są oceany - bez nich byłoby jeszcze smutniej ___ List: Catalyst@lists.rawmode.org Listinfo: http://lists.rawmode.org/mailman/listinfo/catalyst Searchable archive: http://www.mail-archive.com/catalyst@lists.rawmode.org/ Dev site: http://dev.catalyst.perl.org/
