4.4. Moving Forward

In this chapter, we generated scaffolding for a primitive user interface. But there are limits to the scaffolding code. It doesn't manage relationships, so you can't see or edit the photos associated with a category or the slides in a slideshow. The views are also ugly and incomplete. In the next chapter, we'll start to remedy the problems. We'll use the generated scaffolding as a base and build a more complete user interface. Photo Share is moving quickly, and we're not about to slow down.
