catalyst

问题 I'm looking for a initscript to make usage of perlbrew on a webserver running a nginx as proxy for an perl catalyst application. I'm currently trying to start the app via source $PERLBREW execute "perlbrew use perl-5.14.4@devel" execute "mkdir -p $PID_PATH && $START_ICOS_APP > /dev/null 2>&1 &" echo "$DESC started" but it appers it cannot find the local perl installation. $PERLBREW is set to my perlbrew folder. 回答1: This is a good step by step guide how to do this, but it is French (but still

问题 I have a Catalyst application that uses TT for views: https://metacpan.org/module/Catalyst::View::TT and I would like to try out https://metacpan.org/module/Catalyst::View::Xslate We use the WRAPPER directive with Template Toolkit and I am curious if it is at all possible to reuse the wrapper somehow with xslate or would I have to break them into headers and footers? 回答1: You can in theory, by using TTerse syntax. According to the manual, enabling this allows you to use a lot of TT compatible

问题 Using DBIx::Class I am trying to manipulate the data of a column whenever it is being updated or retrieved. For instance, before it goes into the database I would like to encrypt it, and whenever it is being accessed I would like to decrypt it. I am following this example in the DBIx::Class::Manual::Cookbook, however I can't seem to get it to work. I have placed the following in my User schema. For testing I am just using the name column, I know it doesn't make sense: __PACKAGE__->add_columns

问题 Hi I'm trying to figure out catalist and paraview for a while. I tried to run these examples on my paraview but without success. https://github.com/Kitware/ParaViewCatalystExampleCode I imagined at least the python code would run with the python shell. But it doesn't seem to work either. I viewed all the kitware tutorials and some others online. But still no progress. Any help is appreciated. 回答1: You should be able to run all of the non-Python examples with CTest (i.e. ctest executable). I

问题 I'm trying to access the Catalyst config hash from within a model like this (contrived example): package Dabadie::Model::DirFind; use Moose; use namespace::autoclean; extends 'Catalyst::Model';use namespace::autoclean; sub list { my ($self, $c) = @_; return $c->config(); } however, $c is undef, and $self->config returns nothing. Can anyone help figure this one out? Thanks, Simone 回答1: This is as intended - your model is supposed to be separable from your controller logic as per the MVC design

问题 Data defined inside Catalyst app or in templates has correct encoding and is diplayed well, but from database everything non- Latin1 is converted to ? . I suppose problem should be in model class, which is such: use strict; use base 'Catalyst::Model::DBIC::Schema'; __PACKAGE__->config( schema_class => 'vhinnad::Schema::DB', connect_info => { dsn => 'dbi:mysql:test', user => 'user', password => 'password', { AutoCommit => 1, RaiseError => 1, mysql_enable_utf8 => 1, }, 'on_connect_do' => [ 'SET

问题 Is there a way to disabling a WRAPPER that was set in new(\%config), through either the template, or a temporary override with parse() ? I want to have a single default WRAPPER (that I'll use for 99.9% of my templates), but exclude a few. I'm doing this all through Catalyst::View::TT just like the example in the configuration synopsis, except I don't want the WRAPPER to apply to all of my templates. 回答1: Edit the wrapper, to include a conditional like: [% IF no_wrapper OR template.no_wrapper

问题 For example: I know how to match www.domain.com/foo/21 sub foo : Path('/foo') Args(1) { my ( $self, $c, $foo_id ) = @_; # do stuff with foo } But how can I match www.domain.com/foo/21 OR www.domain.com/foo/21/bar/56 ? sub foo : <?> { my ( $self, $c, $foo_id, $bar_id ) = @_; # do stuff with foo, and maybe do some things with bar if present } Thanks Update: Following Daxim's suggestion, I tried to use :Regex sub foo : Regex('foo/(.+?)(?:/bar/(.+))?') { my ( $self, $c ) = @_; my ( $foo_id, $bar

问题 I'm studying to take the data bricks to spark certification exam, and their practice exam ( please see > https://databricks-prod-cloudfront.cloud.databricks.com/public/793177bc53e528530b06c78a4fa0e086/0/6221173/100020/latest.html ) requires us to accept this statement as true fact: "Explicit caching can decrease application performance by interfering with the Catalyst optimizer's ability to optimize some queries" I got this question wrong even though I have read up a lot on the catalyst and

问题 I've tried to use parse_on_demand as shown in: http://search.cpan.org/~flora/Catalyst-Runtime-5.80007/lib/Catalyst.pm#ON-DEMAND_PARSER However, I can't seem to stop the upload. I'm testing this simply by creating an action that dies immediately, however the browser seems to upload the very large file I've selected before it ever reaches my action: sub upload :Local { my ($self, $c) = @_; die; # What I'd like to do is this: # if ($c->req->header('Content-Length') > $some_limit) { # die "Upload
