def self.serialize string, options = {}
  unless string.is_a?(String)
    msg = "expected a String value, got #{string.class}"
    raise ArgumentError, msg  
  end
  string
end

Returns the value cast to a string. Empty strings are returned as nil by default. Type casting is done by calling to_s on the value.

string_attr.type_cast(123)
# => '123'

string_attr.type_cast('')
# => nil

string_attr.type_cast('', :preserve_empty_strings => true)
# => ''

@param [Mixed] value @param [Hash] options @option options [Boolean] :preserve_empty_strings (false) When true,

empty strings are preserved and not cast to nil.

@return [String,nil] The type casted value.
