#_rest_resources(default_singular, name, **kwargs, &block) ⇒ Object

Internal core implementation of the `rest_resource(s)` router, both singular and plural.

Parameters:

  • default_singular (Boolean) —

    the default plurality of the resource if the plurality is not otherwise defined by the controller

  • name (Symbol) —

    the resource name, from which path and controller are deduced by default
