Using BubbleWrap to read JSON files

Question

I have a backend to an IOS application. I am trying to read the data from my rails backend by using JSON. My bubbleWrap get request is as follows.

BW::HTTP.get("url_here/children/1.json") do |response|
   json = BW::JSON.parse response.body.to_str
   for line in json
     p line[:name]
   end
end

It doesn't bring any data back, it actually breaks my code. I can't find any documentation with an example of how to use REST from rubymotion/Bubblewrap and pull data back to my application.

Any help is appreciated.

Always check the response code before parsing the response body. You might

BW::HTTP.get(url) do |response|
  if response.ok?
    data = BW::JSON.parse(response.body.to_str)
    # make sure you have an array or hash before you try iterating over it
    data.each {|item| p item}
  else
    warn "Trouble"
  end
end

Also make sure you sanity-check the JSON response vs your code's expectation. Perhaps the JSON is an array and not a hash?
