want to create a simple form first.so when i brower to "localhost:
3000/
posts/index", it says
"uninitialized constant PostsController::Post
Please somebody help to resolve it
Thanks
You must have a model if you're going to call Post.new. That's where
that 'new' method happens. The model tells the controller what fields
it should initialize, which tells the view that the default values are
whatever they are, etc. It's MVC, not VC!
