Problems with asynchronous calls using motion-resource and BubbleWrap for Ruby Motion - rubymotion

Question

I'm trying to follow the example from motion-resource
https://github.com/tkadauke/motion-resource. Having difficulty getting the data in the correct format with this asynchronous code:
def all_friends(&block)
Friends.find_all do |friends, response|
if response.ok?
puts friends.inspect
block.call friends
else
App.alert response.error_message
end
end
end
In this implementation I have a user resource that has many friends. I'm trying to find all the friends for this user with User.current.all_friends
I'm getting an error when the data comes back when I try to iterate through it because its coming back as a BubbleWrap HTTP Query.
#<BubbleWrap::HTTP::Query:0xc54c7a0 ...>

Answer 1

I wonder what line number your error is coming from.
" undefined method `each' for # "
Have you tried removing this line?
block.call friends?
Your example appears to come from the docs with this working line of code...
User.find_all do |users, response|
if response.ok?
puts users.inspect
else
App.alert response.error_message
end
end
Hope you figure it out. It would be easier to troubleshoot if the code was executable.

This Stack Stack overflow question addresses the same problems experienced in this question: What is the iOS (or RubyMotion) idiom for waiting on a block that executes asynchronously?
