190 Pagination [0.5d]

Goals

• Understand why we use pagination

Exercises

• Create 7500 movies in MovieDB (hint: Doing it in a single transaction is much faster). Load the movies index and measure how long it renders.
• Use the will_paginate gem to add pagination to MovieDB's list of movies. How long does the movies index render now?
• Inspect the HTML generated by will_paginate. Customize the style so it matches the look of your MovieDB.
• tail -f log/development.log and see which queries will_paginate generates. What do they do?
