1)Url field should also accept url as “www.abc.com”. If user enters url like this, it should be automatically appended with “http://” resulting in value saved in database as “http://www.abc.com”. If user enters url as “http://www.xyz.com” system should not append “http://”. User should be able to save url with “https://”. what is the code for it in ruby on rails?
