Question

Could someone point me in the right direction about looping through an array and extracting the required values. It’s causing me issues understanding it:

array = [{"response_message"=>nil, "response_client_message"=>nil, "response_customer_message"=>nil, "closed"=>true, "updated_at"=>2012-05-30 13:20:49 UTC, "created_at"=>2012-05-30 13:20:29 UTC, "token"=>"2fda85eab962fa6e27850605f2f948ca", "price"=>"$24.00", "amount"=>#<BigDecimal:7fa3f4485428,'0.24E2',9(18)>, "currency_code"=>"USD", "metadata"=>"{\"xxx\": 5, \"xxx\": 250, \"xxx\": true, \"support\": { \"email\": true, \"phone\": false } }", "line_items"=>[{"amount"=>#<BigDecimal:7fa3f4482fe8,'0.24E2',9(18)>, "notes"=>nil, "currency_code"=>"USD", "description"=>"1 day", "price"=>"$24.00", "feature_level"=>"{\"hotspots\": 5, \"vouchers\": 250, \"customizable_logins\": true, \"support\": { \"email\": true, \"phone\": false } }", "metadata"=>"{\"hotspots\": 5, \"vouchers\": 250, \"customizable_logins\": true, \"support\": { \"email\": true, \"phone\": false } }"}]}]

One of these is generated each day, I need to loop through and present a few values. I’ve tried this:

array.select{|elem| elem[:updated_at]}

But that gives me a [].

How do I loop through this and extract the values?
I also need to understand how to get the line_items array out too.

Thanks

Answer 1

array.select{|elem| elem["updated_at"]}

pass string not a symbol
