Before moving on to create our posts controller we must first explore something fundamental to all programming and that is CRUD. Crud is used to manage resources which are the main parts of all applications. Just take a moment to think about your next great app idea. It involves managing a resource at its core. Maybe they are tasks, statuses, photos, or posts. The web app is simply a way to create new resources, edit existing ones, delete them or view them.
CRUD Stands for:
C = Create
R = Read
U = Update
