MojoMojo::Schema::Result::PageVersion(3pm)		User Contributed Perl Documentation		MojoMojo::Schema::Result::PageVersion(3pm)

NAME

       MojoMojo::Schema::Result::PageVersion - Versioned page metadata

DESCRIPTION

       This table implements versioning of page metadata (not content, see MojoMojo::Schema::Result::Content for that). It has a composite primary
       key "(page, version)".

       When renaming a page, a new version is created in this table, with "version" set to 1 + the maximum version for that "page". The "status"
       of the new "page_version" is set to "released", its "release_date" is set to "DateTime->now", while the old "page_version"'s status is set
       to 'removed' and its "remove_date" is set to "DateTime->now".

   TODO
       o   document the relationships

       o   in order to support proper rollback, meaning creating a new version for the rollback operation itself, a "content_version" field needs
	   to be added.

       o   "created" is apparently unused: set to 0 for pages populated when creating the database, and NULL for all normal pages.

METHODS

   latest_version
       Return the PageVersion object having the latest version of this page.
