# `MishkaCmsCore.Runtime.Resources.Changes.PublishErrorPageDraft`
[🔗](https://github.com/mishka-group/mishka_cms_core/blob/v0.0.1/lib/mishka_cms_core/runtime/resources/__changes/publish_error_page_draft.ex#L5)

After a `:publish` / `:master_publish` of a `MishkaCmsCore.Runtime.ErrorPageDraft`, writes the
draft's fields (including the whole `error_pages` collection) to the live
`MishkaCmsCore.Runtime.ErrorPage` — creating it when the draft has no `source_error_page_id`,
otherwise updating it.

Scoped to the draft's site (`tenant: draft.site_id`, `authorize?: false`), in an `after_action`, so
a write failure rolls the whole publish transaction back. The ErrorPage analogue of
`MishkaCmsCore.Runtime.Resources.Changes.PublishPageDraft`.
