Method: Entangled::Model::InstanceMethods#channels

Defined in:
lib/entangled/model.rb

#channels(tail = '') ⇒ Object

Build channels. Channels always at least include a collection channel, i.e. /tacos, and a member channel, i.e. /tacos/1, for direct access.

If the model belongs_to other models, nested channels are created for all parents, grand parents, etc recursively
