Instance Method Details

#recursively_symbolize_keys(modify_nested_arrays = false) ⇒ Hash, Array Also known as: recursive_symbolize_keys

Returns a version of the supplies Hash or Array with all Hash keys symbolized.

Parameters:

  • modify_nested_arrays (Boolean) (defaults to: false) —

    set to true to iterate over array contents. Defaults to false.

Returns:

  • (Hash, Array) —

    recursively symbolized Array or Hash

#recursively_symbolize_keys!(modify_nested_arrays = false) ⇒ Hash, Array Also known as: recursive_symbolize_keys!

Recursively symbolize all keys in hashes.

Parameters:

  • modify_nested_arrays (Boolean) (defaults to: false) —

    set to true to modify array contents. Defaults to false.

Returns:

  • (Hash, Array) —

    recursively symbolized Array or Hash
