having trouble with bubblewrap

bw.rb

People.get_people do |data|
  @data = data
end


def self.get_people(&block)
  BW::HTTP...do |response|
    @people = BW::JSON...
    block.call(@people)
  end
end

#got this working as a find method:

def self.find(id, &block)
  BubbleWrap::HTTP.get("http://myapp.com/api/#{id}.json") do |response|
    @person = BW::JSON.parse(response.body)
    block.call(@person)
  end
end

#called like

def selected_person(id)
    Person.find(id) do |p|
      @person = p
    end
    @person
  end

#where @person is now available throughout the controller, although its still not really right as I need to specify the 0th #member of @person i.e.

def viewDidAppear(animated)
    self.title = @person[0]['first_name'] + " " + @person[0]['last_name']
      
    @label = UILabel.alloc.initWithFrame(CGRectZero)
    @label.text = "Email: " + @person[0]['email']    
    @label.sizeToFit
    @label.center = CGPointMake(self.view.frame.size.width / 2, self.view.frame.size.height / 2)
    self.view.addSubview @label
end    

#But I just can't seem to get the "index" call to work properly.

#I'm getting `undefined method `count' for #<BubbleWrap::HTTP::Query:0x6c08560 ...> (NoMethodError)` errors, the count coming in #the numberOfRowsInSection call.

def self.get_people(&block)
  BubbleWrap::HTTP.get("http://vaynernet.com/api.json") do |response|
    @ppl = BW::JSON.parse(response.body.to_str)
    block.call(@ppl)     
  end
end

def viewDidLoad
    super
    self.title = "Directory"
    
    Person.get_people do |people|
      @data = people
    end
...
end

Should I not be calling the Person.get_people class method in viewDidLoad? Or does this sound like the json im returning from my rails server is the issue? It's increasingly perplexing because the Person.find method is working well enough.
