NAME

Strehler::Element::Role::Slugged - A role to manage element's slug

DESCRIPTION

A slugged Strehler element provides an authomatic management of a slug (multilanguage or not). Slug can then be used to retrieve the element itself.

Default implementation that come with the role is the one used by Strehler::Element::Article but methods can be overridden for different behaviours.

A slugged element must include, in its database representation, a field named slug (VARCHAR), in the main table or in the table of multilanguage contents.

SYNOPSIS

my $article = Strehler::Element::Article->get_by_slug('a-slug-suitable-for-web', $language)

Return 1 if the slug is multilanguage and comes from the multilanguage contents table.

save_slug
