def accepts_method_with_media_type?(resource_method, entity)
  method_name = "accepts_#{resource_method}_with_media_type?"
  if respond_to?(method_name)
    send(method_name, entity)
  else
    target && target.accepts_method_with_media_type?(resource_method, entity)
  end
end

#authorize(user, method) ⇒ Object

Some methods which should return something other than nil by default for an empty target:

# File 'lib/doze/resource/proxy.rb', line 71

def authorize(user, method)
  target ? target.authorize(user, method) : true
end

def other_method(method_name, entity=nil)
  if respond_to?(method_name)
    send(method_name, entity)
  else
    target && target.other_method(method_name, entity)
  end
end

#post(entity, session) ⇒ Object

proxying post is a bit fiddly due to the (in retrospect perhaps a bit unadvised) convenience support for different method arities for post. maybe move to post_with_session(entity, session) vs post(entity) if this causes any more pain.

#try(method, *args, &block) ⇒ Object

Methods based around use try / respond_to? need special care when proxying:
