NAME

Ado::Plugin::AdoHelpers - Default Ado helpers plugin

SYNOPSIS

# Ado
$self->plugin('AdoHelpers');

# Mojolicious::Lite
plugin 'AdoHelpers';

DESCRIPTION

Ado::Plugin::AdoHelpers is a collection of renderer helpers for Ado.

This is a core plugin, that means it is always enabled and its code a good example for learning to build new plugins, you're welcome to fork it.

See "PLUGINS" in Ado::Manual::Plugins for a list of plugins that are available by default.

HELPERS

Ado::Plugin::AdoHelpers implements the following helpers.

do_sql_file

Your plugin may need to add some new tables, add columns to already existing tables or insert some data. This method allows you to do that. See the source code of Ado::Plugin::Vest for example. The SQL file will be slurped, multiline comments will be removed. The content will be split into ';' and each statement will be executed using "do" in DBI.

# in a plugin somewhere in register
$app->do_sql_file(catfile($self->config_dir, $sql_file));
$app->do_sql_file($conf->{vest_data_sql_file});

# on the command line
$ ado eval 'app->do_sql_file(shift)' some_file.sql

# elsewhere in an application
$app->do_sql_file($sql_file)

to_json

my $chars = $c->to_json({name =>'Петър',id=>2});
$c->stash(user_as_js => $chars);
# in a javascript chunk of a template
var user = <%== $user_as_js %>;
var user_group_names = <%== to_json([user->ingroup]) %>;

Suitable for preparing JavaScript objects from Perl references that will be used from stash and in templates.

user

Returns the current user. This is the user guest for not authenticated users. This helper is a wrapper for "user" in Ado::Control.

$c->user(Ado::Model::Users->query("SELECT * from users WHERE login_name='guest'"));
#in a controller action:
my $current_user = $c->user;
#in a template:
<h1>Hello, <%=user->name%>!</h1>

METHODS
