# `MishkaCmsCore.Runtime.Resources.Actions.RestoreVersion`
[🔗](https://github.com/mishka-group/mishka_cms_core/blob/v0.0.1/lib/mishka_cms_core/runtime/resources/__actions/restore_version.ex#L5)

The body of a versioned resource's `:restore_version_api` (a site's own call) and
`:master_restore_version` (a master's) generic actions: read the record, refuse what may not be
restored, check that the version is one of THIS record's, and run the resource's `:restore_version`
update with the record's own site as the tenant.

The outer action is authorized by the resource's policies; the reads and the update here run as
the system, so the checks below are the whole of what stands between a caller and the record.

## Options

  * `:resource` and `:version` — the resource and its AshPaperTrail version resource. The version
    resource must have a `:get_any` read, and the resource a `:restore_version` update.
  * `:read` — the read action that finds the record: `:read` for a site's call, `:master_get` for a
    master's, `:get_any` for a resource that may be global.
  * `:tenant_read?` — read in the tenant of `SiteWithGlobals.acting_site/1` (a site's call on a
    resource that is never global).
  * `:global?` — a site's call on a resource that may be global: a global record is not found by a
    caller with no site, and may not be restored by a site (`:global` words the refusal).
  * `:archived` and `:foreign` — the refusals for an archived record and for a version of another
    record, written with `dgettext_noop("errors", …)` where the action is declared.

A call with no site, or on another site's record, finds nothing.
