1. Discovering a world of
Resources on Rails
David Heinemeier Hansson

2. Create Read Update Delete

3. What they told you...
Simplistic
Unfulfilling
Unworthy
Shameful

4. They were wrong

5. How I learned to stop
worrying and love the CRUD

6. find create update destroy
SELECT INSERT UPDATE DELETE

7. GET POST PUT DELETE
find create update destroy
SELECT INSERT UPDATE DELETE

8. POST /people/create
GET /people/show/1
POST /people/update/1
POST /people/destroy/1

9. POST /people
GET /people/1
PUT /people/1
DELETE /people/1

16. Why bother?
Consistency
Simplicity
Discoverability

17. Constraints are liberating
(a straight jacket for your mind)

24. Model beyond “things”
Relations (membership, subscription)
Events (closure, change)
States (reviewed, accepted)

26. But!

27. CRUD is not a goal,
it’s an aspiration,
a design technique

29. POST /kases/1;close
/identity;aspect
GET /kases/1;edit
/identity;view

32. And there is more!

33. Answering to mime types
One controller for many clients
One action returning different results
Flexible input model

47. One more thing
