Post, and I want to have an action where I update all posts from that user.:update action for that. But it seems that both :create, :update and :destroy actions are only meant to run with only one resource/changeset at a time.:update action, I would need to pass an empty changeset of a Post which doesn't mean anything to what I'm trying to do since inside the action I would ignore that changeset entirely, fetch all posts filtered by the actor id and update them.:read since a :read action don't expect a changeset as an input. But, at the same time it seems wrong to use a :read action to update rows...
