PageVersion

Version history for pages: every snapshot of a versioned page's content and image. There is always exactly one current version per page; the others are archived.

Columns

Column	Type	Notes
page_id	bigint	required
name	string	version label, auto-generated from the page title and date
content	jsonb	ProseMirror content snapshot
image_data	jsonb	Shrine attachment snapshot
current_since	datetime	set ⇔ this is the current version

Behavior

• belongs_to :page — with Page#versions ordered most recent first
• Validations guarantee one and only one current version per page
• after_initialize sets a default name like "Page title (2026-06-10)"
• Includes Sectionable, RecordImageUploader::Attachment(:image) and strip_attributes

Notable methods

Method	Returns
current?	whether this version is the live one
other_versions	the page's other versions
current_image / current_image_url	this version's image
