Class Method Details

.find_by(remote_attr, value) ⇒ Object

This is always invoked via class#find_remote_resource_by by class#fetch_by. It gives the remote model an opportunity to discover a remote object that doesn’t have a local counterpart. NullRemote should never discover something that doesn’t exist locally.

.find_by_for_local(local_record, remote_key, fetch_value) ⇒ Object

This is always invoked by instance#fetch_remote_resource. It expects to find a remote counterpart for a local resource. It should always return a NullRemote object that doesn’t alter the behavior of a normal model at all.

Instance Method Details

#[]=(attribute, value) ⇒ Object

NullRemote needs to receive setter messages and swallow them. It doesn’t need to respond to getter messages since it has nothing to say.
