Access property in JSON response - ruby-on-rails

Question

I'm looking to grab the image 'src' within this JSON response, but my trying has left me at a loose end. Any help would be brilliant.
My Model
def test
response = self.class.get("URLFORRESPONSE")
#elements = response.parsed_response["extractorData"]
#parsed = #elements.collect { |e| e['src'] }
end
JSON Response
{
"extractorData" : {
"url" : "http://testwebsite.com/",
"resourceId" : "409417ee21618b70d74b03231a793c2d7",
"data" : [ {
"group" : [ {
"image" : [ {
"src" : "test0.jpg"
} ]
}, {
"image" : [ {
"src" : "test1.jpg"
} ]
}, {
"image" : [ {
"src" : "test2.jpg"
} ]
}, {
"image" : [ {
"src" : "test3.jpg"
} ]
}, {
"image" : [ {
"src" : "test4.jpg"
} ]
}

Answer 1

Your JSON is invalid. It should be:
{
"extractorData": {
"url": "http://testwebsite.com/",
"resourceId": "409417ee21618b70d74b03231a793c2d7",
"data": [{
"group": [{
"image": [{
"src": "test0.jpg"
}]
}, {
"image": [{
"src": "test1.jpg"
}]
}, {
"image": [{
"src": "test2.jpg"
}]
}, {
"image": [{
"src": "test3.jpg"
}]
}, {
"image": [{
"src": "test4.jpg"
}]
}]
}]
}
}
To extract the src's:
#parsed = #elements['data'][0]['group'].map{| g | g['image'][0]['src'] }

I know this is ugly as hell but i hope this sugestion helps.
Since HTTParty.parsed_response returns a hash and assuming you're using ruby 2.3, you can do:
#elements = response.parsed_response["extractorData"]
#elements.dig('data').collect{|h| h.dig('group').collect{|h| h.dig('image').collect{|h| h.dig('src')}}}
see it:
h = {"extractorData"=>{"url"=>"http://testwebsite.com/", "resourceId"=>"409417ee21618b70d74b03231a793c2d7", "data"=>[{"group"=>[{"image"=>[{"src"=>"test0.jpg"}]}, {"image"=>[{"src"=>"test1.jpg"}]}, {"image"=>[{"src"=>"test2.jpg"}]}, {"image"=>[{"src"=>"test3.jpg"}]}, {"image"=>[{"src"=>"test4.jpg"}]}]}]}}
h.dig('extractorData', 'data').collect{|h| h.dig('group').collect{|h| h.dig('image').collect{|h| h.dig('src')}}}
=> [[["test0.jpg"], ["test1.jpg"], ["test2.jpg"], ["test3.jpg"], ["test4.jpg"]]]
