Conclusion

We’ve come now to the end of the 30,000-foot view of a Rails application. The demo app developed in this chapter has several strengths and a host of weaknesses.

Strengths
• High-level overview of Rails
• Introduction to MVC
• First taste of the REST architecture
• Beginning data modeling
• A live, database-backed web application in production

Weaknesses
• No custom layout or styling
• No static pages (like ‘‘Home’’ or ‘‘About’’)
• No user passwords
• No user images
• No signing in

• No security
• No automatic user/micropost association
• No notion of ‘‘following’’ or ‘‘followed’’
• No micropost feed
• No test-driven development
• No real understanding

The rest of this tutorial is dedicated to building on the strengths and eliminating the weaknesses.
