#camelize_keys(first_letter = :upper) ⇒ Object

Returns a new hash with all keys converted to UpperCamelCase strings.If th is set to :lower then camelize produces lowerCamelCase.

hash = { my_name: 'Rob', my_age: '28' }

hash.camelize_keys
# => {"MyName"=>"Rob", "MyAge"=>"28"}

hash.camelize_keys(:lower)
# => {"myName"=>"Rob", "myAge"=>"28"}

def camelize_keys(first_letter = :upper)
  transform_keys { |key| key.to_s.camelize(first_letter) rescue key }
end

#camelize_keys!(first_letter = :upper) ⇒ Object

Destructively converts all keys to strings. Same as camelize_keys, but modifies self.

end

#deep_camelize_keys(first_letter = :upper) ⇒ Object

Returns a new hash with all keys converted to UpperCamelCase strings.If th is set to :lower then camelize produces lowerCamelCase. This includes the keys from the root hash and from all nested hashes and arrays.

hash = { my_name: 'Rob', my_age: '28', my_friend: { his_name: "bob" } }

hash.deep_camelize_keys
# => {"MyName"=>"Rob", "MyAge"=>"28", "MyFriend"=>{"HisName"=>"bob"}}
