You can just make a new hash of HashWithIndifferentAccess type from your hash.

hash = { "one" => 1, "two" => 2, "three" => 3 }
=> {"one"=>1, "two"=>2, "three"=>3}

hash[:one]
=> nil 
hash['one']
=> 1 


make Hash obj to obj of HashWithIndifferentAccess Class.

hash =  HashWithIndifferentAccess.new(hash)
hash[:one]
 => 1 
hash['one']
 => 1
