MishkaCmsCore.Runtime.Resources.Changes.SetRecordKind (Mishka CMS Core v0.0.1)

Writes the action's record argument — the kind of record each address of a page shows, "blog:post" — into extra["record"], where MishkaCmsCore.Runtime.Seo.record_of/1 reads it. An empty one takes it out: the page shows one thing at one address.

The kind is a key of extra rather than a column, and the forms offer it as a field of its own, so the actions that save those forms take it as an argument and this puts it in place. It merges into the extra the same changeset is writing, so a form that edits both keeps both. An action that is not handed the argument leaves extra as it is.

  argument :record, :string, allow_nil?: true
