Using a Background Image

• Create a Rails project (scaffold-based or custom controller) and

The LinkIcons Example

• Look at the LinkIcons Example that we implemented on 10/14.
• Experiment with the CSS code for the icon classes. Verify that the settings for
  

  text-indent  white-space  
  overflow  background-size
  

  are all necessary.

Using ActiveRecord

• ActiveRecord Queries
• Use the Rails Console to check out some of the ActiveRecord Queries. Use the seed file from the Hospital1 Example.  Delete all lines except the Patient data.
• Practice Problem: Set up a scaffold-based project with model Photo, fields description, and file_name. Write a loop that displays all of the photos in a view in order of most recent to least recent. Use these photos for your project: dogs-owners.zip.
  Ans: See the PhotoGallery Example.

The Depot1 Example

• Design and implement Version 1.0 of a Depot project that implements a shopping cart. (This example starts on Page 91 of the Ruby, Thomas, and Hansson textbook.)
• What models are needed to implement a shopping cart?
  Ans: Here are four models with some suggested fields. Photo thanks to Gabriela.
