How to convert a ruby hash object to JSON? So I am trying this example below & it doesn’t work?
I was looking at the RubyDoc and obviously Hash object doesn’t have a to_json method. But I am reading on blogs that Rails supports active_record.to_json and also supports hash#to_json. I can understand ActiveRecord is a Rails object, but Hash is not native to Rails, it’s a pure Ruby object. So in Rails you can do a hash.to_json, but not in pure Ruby??
car = {:make => "bmw", :year => "2003"}
car.to_json
