Consume JSON - Shopify API response - ruby-on-rails

Question

I'm trying to work with what I think is a JSON response from Shopify. It looks like this:
=> #<ActiveResource::Collection:0x007f61f45c3840
#elements=
[#<ShopifyAPI::Product:0x007f61f45c3638

The response I get from searching for a product via the Shopify API is of the class:
ActiveResource::Collection
I first tried turning that to JSON with .to_json but thats just a string and I can't loop thru it easily.
I then tried to turn it to an array with .to_a but now I can't get into the data..
The original response is in the x variable and now its an array.. If I try
x[0] - I get the original response back
x[1] - nil
X[0]["id] - NoMethodError: undefined method `[]' for
#<ShopifyAPI::Product:0x007f61f45c3638>
x["id"] - TypeError: no implicit conversion of String into Integer
x[0][0] - NoMethodError: undefined method `[]' for
#<ShopifyAPI::Product:0x007f61f45c3638>
x[0].class - Shopify::Product which is a ActiveResource::Collection
x[0].to_array - NoMethodError: undefined method `to_array' for
#<ShopifyAPI::Product:0x007f61f45c3638>

Answer 1

The data you show is an array of Product instances. Simply take the data, which I'll call data, and loop through it to get each product.
data.each do |product|
puts product.title
puts product.vendor
end
You can obviously extend your functionality from here.
