NAME

Template::Provider::CustomDBIC - Load templates using DBIx::Class

SYNOPSIS

use My::CustomDBIC::Schema;
use Template;
use Template::Provider::CustomDBIC;

my $schema = My::CustomDBIC::Schema->connect(
    $dsn, $user, $password, \%options
);
my $resultset = $schema->resultset('Template');

If all of your templates are stored in a single table the most convenient method is to pass the provider a DBIx::Class::ResultSet.

my $template = Template->new({
    LOAD_TEMPLATES => [
        Template::Provider::CustomDBIC->new({
            RESULTSET => $resultset,
            # Other template options like COMPILE_EXT...
        }),
    ],
});

# Process the template in 'column' referred by reference from resultset 'Template'.
$template->process('table/reference/column');

DESCRIPTION

Template::Provider::CustomDBIC allows a Template object to fetch its data using DBIx::Class instead of, or in addition to, the default filesystem-based Template::Provider.

SCHEMA

This provider requires a schema containing at least the following:

• A column containing the template name. When $template->provider($name) is called the provider will search this column for the corresponding $name. For this reason the column must be a unique key, else an exception will be raised.
• A column containing the actual template content itself. This is what will be compiled and returned when the template is processed.
• A column containing the time the template was last modified. This must return
• or be inflated to - a date string recognisable by Date::Parse.

OPTIONS

In addition to supplying a RESULTSET or SCHEMA and the standard Template::Provider options, you may set the following preferences:

• COLUMN_NAME

  The table column that contains the template name. This will default to 'name'.

• COLUMN_CONTENT

  The table column that contains the template data itself. This will default to 'content'.

• COLUMN_MODIFIED

  The table column that contains the date that the template was last modified. This will default to 'modified'.

METHODS

->fetch( $name )

This method is called automatically during Template's ->process() and returns a compiled template for the given $name, using the cache where possible.

USE WITH OTHER PROVIDERS

By default Template::Provider::CustomDBIC will raise an exception when it cannot find the named template

my $template = Template->new({
    LOAD_TEMPLATES => [
        Template::Provider::CustomDBIC->new({
            RESULTSET => $resultset,
        }),
        Template::Provider->new({
            INCLUDE_PATH => $path_to_templates,
        }),
    ],
});

CACHING

When caching is enabled, by setting COMPILE_DIR and/or COMPILE_EXT, Template::Provider::CustomDBIC will create a directory consisting of the database DSN and table name. This should prevent conflicts with other databases and providers.

DIAGNOSTICS

In addition to errors raised by Template::Provider and DBIx::Class, Template::Provider::CustomDBIC may generate the following error messages:

• A valid DBIx::Class::Schema or ::ResultSet is required

  One of the SCHEMA or RESULTSET configuration options must be provided.

• %s not valid: must be of the form $table/$template

  When using Template::Provider::CustomDBIC with a DBIx::Class::Schema object, the template name passed to ->process() must start with the name of the result set to search in.

• '%s' is not a valid result set for the given schema

  Couldn't find the result set %s in the given DBIx::Class::Schema object.

• Could not retrieve '%s' from the result set '%s'

DEPENDENCIES

• Carp
• Date::Parse
• File::Path
• File::Spec
• Template::Provider

Additionally, use of this module requires an object of the class DBIx::Class::Schema or DBIx::Class::ResultSet.
