Hello Friends
In this lecture, you will learn how to change the type of attribute in a database table. This is a very simple but interesting topic to learn. At the end of the video, you will get 4 basic but very good questions so that you can prepare this change_column in a better way at your end. You will also get to know that what happens if you don't use reversible or #up #down methods to change migration in rails.
Please watch the complete video.
Thanks
