[Catalyst] PageCache clear cached page
HEllo! I' trying to cleaner for cached page as shown in
http://dev.catalyst.perl.org/wiki/SolvedIssues#si.20
Exempting specific pages from cacheing.
I've create MyApp.yml:
...
page_cache:
expires: 60
set_http_headers: 1
auto_cache:
- (?!.*/(debug|expire)\z).*
# cache everything but requests ending in /(debug|expire)
and added some constructions to my Root.pm:
sub begin : Private {
my ( $self, $c ) = @_;
if ($c-config-{page_cache} $c-req-path =~ m#(.*)/expire$#) {
$c-clear_cached_page( '/' . $1 );
}
}
I run myapp_server.pl
After run pages autocaches, but it wont to get extra content (such as CSS or
images)
And using of /expire on root http://localhost:3000/expire get 404 error defined
by me in Root.pm
On other pages such as http://localhost:3000/network/expire - it work with
errors, Network.pm Controller want input parameter (int) net_id
(http://localhost:3000/network/1) so expire work and after that controller
reports an error wrong param (it's passed to database and query witn wrong
param fails )
Where is my mistake?

RE: [Catalyst] Catalyst test server response times.
Hi Ian doing a 'host' command on an IP address works instantly and the contents of the /etc/resolv.conf file look to be correct. Could it be a problem with specific IP addresses rather than with the nameservers? (I can't cause a problem manually with the IP addresses I know the Catalyst app is run from). There are a few things you could try to narrow the problem. 1. You're definitely running the server without flags? i.e. $ perl script/myapp_server.pl The -k and -d flags slow it down a lot. 2. You've got the latest code? $ cpan Catalyst::Devel 3. Use the debugger to see where the program is $ perl -d script/myapp_server.pl Fire up a request from your browser. If it's slow, press CTRL-C to break in the debugger and use 'v'iew, '.' and 'T'race to see where you are. It may seem hit and miss but it's a quick way to see where the program is at. You can use 'c'ontinue to complete dispatching. Some more notes at http://catwiki.toeat.com/fromtrac/debugsample 4. Use DProf to profile a couple of requests. $ PERL5OPT=-d:DProf perl script/myapp_server.pl Do a few requests in your browser $ dprofpp Will show you which routines are eating up time. 5. Use a browser debugging tool like Fiddler2 in IE http://www.fiddlertool.com/fiddler/ or Charles in FF http://www.xk72.com/charles/ if you suspect there's some browser - server idiocy going on. See when the request is sent, see when the header comes back. See how long it takes to get the ancillary .css .js .jpg files. That will indicate whether it's a network problem, the server, or simply slow javascript.

The actual execution of the various controllers is very quick (sub 0.3 seconds) If I use CATALYST_DEBUG=0 then the problem goes away. Lately, the problem has gone away even without turning debug off. One possibility I am still investigating is that the problem only occurs if two or more developers are running a server at the same time.

[Catalyst] Malformed class Name Hidden files
Greetings. I am trying to get started with catalyst and am running into slightly annoying problem. I am working though Catalyst::Manual::Tutorial and when it comes time to start the web-server I get this error: Malformed class Name MyApp::Model::._MyAppDB at /usr/local/perl5.8.3/ lib/site_perl/5.8.3/Catalyst.pm line 1875 Compilation failed in require at script/myapp_server.pl line 53. I have traced this down to the fact that my text editor (TextMate) likes to leave hidden files around with similar names as those being edited. For example the above error says something about ._MyAppDB where this a file named MyApp/lib/MyAppDB.pm AND a file MyApp/ lib._MyAppDB.pm If i delete the ._* file the server will launch and everything works fine. My question is: Is there a way I can tell the scripts to ignore hidden files? thanks in advance -Rajeev Cyrus ___ List: Catalyst@lists.scsys.co.uk Listinfo: http://lists.scsys.co.uk/cgi-bin/mailman/listinfo/catalyst Searchable archive: http://www.mail-archive.com/catalyst@lists.scsys.co.uk/ Dev site: http://dev.catalyst.perl.org/

My question is: Is there a way I can tell the scripts to ignore hidden files? This issue has come up at least 129387 times in the past. Please read the archives. Yes, unfortunately it's never been freaking fixed, which is why it's come up 129387 times (at least). I did submit a patch to Simon Wistow for Module::Pluggable in September. It made Module::Pluggable ignore editor junk files by default, though it didn't catch ._* files (easy enough to add). Unfortunately he never responded. And yes, editors delete the files when they're closed, but in the case of Emacs, it creates such files _while_ you're editing a buffer, and it's easy to have your Cat dev server try to load these. So maybe someone can either A) poke Simon or B) we could subclass Module::Pluggable and add the fix in there or C) yell at people who complain about it on the list because they expect the software to do the right thing. -dave /*=== VegGuide.Orgwww.BookIRead.com Your guide to all that's veg.

RE: [Catalyst] Catalyst test server response times.
Just giving my recommendation for what in my opinion is an ESSENTIAL tool for any web developer or even power user Firebug for Firefox https://addons.mozilla.org/en-US/firefox/addon/1843 . Best overall tool I have found. Lets you debug JavaScript, inspect elements and their dom properties, lets you modify anything live and see the change, displays http requests with both post data and returned data, shows response times for each request item, profiles JavaScript on page, list just goes on and on.

In short, I'm new to Catalyst and a near intermediate Perl programmer.
I've converted (and vastly improved) my app from CGI::Application to
Catalyst within an amount of time that made me feel like I wasted
those months I spent prior to using Catalyst. However, the past few
days I have been struggling with this one function that I just can't
get.
Honestly, I feel the easiest way for me to explain is to say that this
headache began by me trying to translate this bit of PHP code to
Perl/Catalyst:
http://www.gregphoto.net/index.php/2007/01/16/scriptaculous-sortables-with-ajax-callback/
I'm just stuck. I've tried many things. My current/pressing attempt to
implement this is in a newsletter app where there is a has many
relationship between a Newsletter table and a table for Articles. The
join table has 3 columns – newsletter_id, article_id and ordering. So
I want to use that PHP and Ajax to allow a user to set the order that
articles will appear in a given newsletter. However, some articles
might appear in multiple newsletters. I might be going about this all
wrong and I would love to hear any suggestion of a better way.
For what it is worth, here is my current effort. I don't know if this
is the closest I've gotten, but it's where I'm at right now. This is
not actually my attempt at the the above, it's really just a scaled
back attempt to just figure out the DBIx for it begin sent by a basic
HTML form and not any Ajax shenanigans.
sub reorder : Local {
my ($self, $c ) = @_;
# This just gets the the value for the later redirect to stay on
the same page
my $link = $c-request-params-{link};
# This is from a hidden value in a loop in the template [%
article.id %]
my @articles = $c-request-params-{article_id};
# Value for the newsletter we're working on. Again, this is from a
hidden value
my $newsletter_id = $c-request-params-{newsletter_id};
# This is obviously where I start trying shit to see if I can get
it to work
# The basic goal is to drop in the new value for ordering for each
unique
# article_id and newsletter_id in turn
foreach my $article ( @articles ) {
my $newsletter = $c-model('SASSDB::ArticleNewsletter')-
search(
{
article_id = $article,
newsletter_id =
$newsletter_id
}
);
my @orderings = $c-request-params-{ordering};
foreach my $ordering ( @orderings ) {
$newsletter-update(
{
ordering = $ordering
}
);
}
}
$c-response-redirect($c-uri_for(/admin/newsletters/
picked_articles/$link));
}
This reasonably gives me the following:
DBIx::Class::ResultSet::update(): DBI Exception: DBD::mysql::st
bind_param failed: Illegal parameter number [for Statement UPDATE
articles_newsletters SET ordering = 1 WHERE ( ( ( article_id = ? ) OR

line 200
Line 200 is $newsletter-update(
The body_parameters are:
body_parameters = {
_submit = Update,
_submitted_edit_menu = 1,
_submitted_form_create = 1,
article_id = [12, 18],
id = 1,
link = Test,
newsletter_id = 1,
ordering = [1, 2],
},
Let me know if you want to see anything else.
Humbly placing myself on the mercy of the community,

I don't know if it'll solve all your problems, but this is definitely wrong:
my @articles = $c-request-params-{article_id};
...
foreach my $article ( @articles ) {
You're assigning an arrayref to the first item in @articles.
Do this instead:
my $articles = $c-request-params-{article_id};
# if there was only 1 article_id submitted, it won't be an arrayref
# make sure it's an arrayref, so the loop below doesn't break
$articles = [$articles] if ref $articles ne 'ARRAY';
# dereference the arrayref
for my $id (@$articles) { ... }
