RXNGIF

This will be our first database-backed, CRUD application.

To start out, you have access to the following methods for free:

• Picture.all returns an Array of Hashes. Each Hash represents one picture, and has two keys: :source (the URL of the picture) and :caption (a note about the picture).
• Picture.first returns the first Hash in the Array.
• Picture.last returns the last Hash in the Array.
• Picture.find(id) returns the element of the Array at the idth position.

Challenge One

Support the following URL:

http://localhost:3000/pictures

The resulting page should display a list of all of the pictures' captions.

Challenge Two

Support the following URL:

http://localhost:3000/pictures/3

The resulting page should display the details (the image and the caption) of the picture at the fourth position in the list. This should be a dynamic route, so that any position number can be plugged in after the last slash.

Challenge Three

Support the following URL:

http://localhost:3000/pictures/new

The resulting page should display a form to add a new picture.

The form should have two input fields: one for Source, and one for Caption.

When the user clicks "Submit", the browser should send the data to the URL http://localhost:3000/create_picture. (You don't have to support that URL yet, just make the form go there. You should end up with a NO ROUTE error.)

Challenge Four

On the page with the list of all of the pictures, make each picture's caption a link to that picture's details page.
