Hello everyone. I'm just beginning my journey with rails and I have many questions though I'll start with just one. I was wondering what happens if you undermine a migration by changing the database schema manually. For example. I generate a model and in the first migration I create a table with an fname and lname column. I then manually remove the lname column using my favorite SQL administration tool. Forgetting that I've made that manual alteration I then create a second migration that adds and email column. When i apply that migration will the model be aware that the db structure was modified outside of the migration sequence and re-apply the missing column? Thanks much.

Don't do that. You'll be happier.
No it won't.
