Why do certain things automatically happen?

We made the scaffold and specified name:string content:text

That being said, why is there automatically edit and delete buttons, why does the page automatically come up as "Statuses"? What defines all of this?

It's a programming design pattern. Where in, when creating the scaffold you are talking about what each individual item will contain. The class however, needs to be pluralized being that it can hold more than one item.

Rails is one of the few frameworks ( for any language ) that do this automatically. I actually prefer it, it forces you to stick with a proper design pattern which in turn often results in better code, that is easily maintained and easily scale-able in the future.

As for the edit and delete buttons, it isn't inconceivable that if you want to be able to create an item, that you'd like to be able to edit and delete them as well. Rails does this automatically specifically to save you time as a developer. And let me tell you, as a developer, the more time our tools save us the better.

After taking a few more lessons, it made sense. It's really awesome and I'm in love with Rails!

I feel you there. I've done PHP for 20 years, have known the basics of ruby for a few years but nothing substantial. Now, I definitely like it -- even getting ready to start converting all my mobile app api's over to it. Should be fun!
