How do I convert a Ruby hash so that all of its keys are symbols?

Question

I have a Ruby hash which looks like:

{ \"id\" => \"123\", \"name\" => \"test\" }

I would like to convert it to:

{ :id         


        

Answer 1

def symbolize_keys(hash)
   new={}
   hash.map do |key,value|
        if value.is_a?(Hash)
          value = symbolize_keys(value) 
        end
        new[key.to_sym]=value
   end        
   return new

end  
puts symbolize_keys("c"=>{"a"=>2,"k"=>{"e"=>9}})
#{:c=>{:a=>2, :k=>{:e=>9}}}
