Data defined inside Catalyst app or in templates has correct encoding and is diplayed

  • 0

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 NAMES utf8',
     ],      
     }
);

1;

I see no flaws here, but something must be wrong. I used my schema also with test scripts and data was well encoded and output was correct, but inside Catalyst app i did not get encoding right. Where may be the problem?

EDIT

For future reference i put solution here: i mixed in connect info old and new style.

Old style is like (dsn, username, passw, hashref_options, hashref_other options)

New style is (dsn => dsn, username => username, etc), so right is to use:

 connect_info => {
     dsn               => 'dbi:mysql:test',
     user              => 'user',
     password          => 'password',
     AutoCommit        => 1,
     RaiseError        => 1,
     mysql_enable_utf8 => 1,
     on_connect_do     => [
             'SET NAMES utf8',
     ],      
 }

    In a typical Catalyst setup with Catalyst::View::TT and Catalyst::Model::DBIC::Schema you’ll need several things for UTF-8 to work:

    • add Catalyst::Plugin::Unicode::Encoding to your Catalyst app
    • add encoding => 'UTF-8' to your app config
    • add ENCODING => 'utf-8' to your TT view config
    • add <meta http-equiv="Content-type" content="text/html; charset=UTF-8"/> to the <head> section of your html to satisfy old IEs which don’t care about the Content-Type:text/html; charset=utf-8 http header set by Catalyst::Plugin::Unicode::Encoding
    • make sure your text editor saves your templates in UTF-8 if they include non ASCII characters
    • configure your DBIC model according to DBIx::Class::Manual::Cookbook#Using Unicode
    • if you use Catalyst::Authentication::Store::LDAP configure your LDAP stores to return UTF-8 by adding ldap_server_options => { raw => 'dn' }

    According to Catalyst::Model::DBIC::Schema#connect_info:

    The old arrayref style with hashrefs for DBI then DBIx::Class options is also supported.

    But you are already using the ‘new’ style so you shouldn’t nest the dbi attributes:

    connect_info => {
     dsn               => 'dbi:mysql:test',
     user              => 'user',
     password          => 'password',
     AutoCommit        => 1,
     RaiseError        => 1,
     mysql_enable_utf8 => 1,
     on_connect_do     => [
         'SET NAMES utf8',
     ],      
}
