Dynamic Method Handling

Instance Method Details

#convert_to_data_type_from_string(type, value) ⇒ Object

Question: Should I refactor these methods into an action_class? Answer: NO Why: We need them in both the action and in load_current_value. If you put them in the action class then they're only in the Provider class and are not available to load_current_value
