How to nest resources

Motivation Why care about REST? What can REST do for you?

Why care about REST?

What can REST do for you?

… Fewer decisions to make More easily understand other’s work, or your own older work Nice URLs Convenient named routes XML/JS/JSON responses, easier

Nice URLs

Convenient named routes

The REST Mindset Think in terms of: C reate  GET /items/new R etrieve  GET /items/1 U pdate  PUT /items/1 D elete  PUT /items/1;delete Let the constraints imposed by CRUD guide your controller design

Think in terms of:

C reate  GET /items/new

R etrieve  GET /items/1

U pdate  PUT /items/1

D elete  PUT /items/1;delete

Let the constraints imposed by CRUD guide your controller design

Let’s code a Nested Resource

Review: Nested Resources Create the resource scaffolding and migrations Set up relationships in models Modify routes.rb Modify the controller of the nested resource add a before_filter amend the *_url calls in create and update actions scope your Comment (nested class) finders to the Post (nestee class) Modify the views Provide a link to the nested resource

Create the resource scaffolding and migrations

Set up relationships in models

Modify routes.rb

Modify the controller of the nested resource

add a before_filter

amend the *_url calls in create and update actions

scope your Comment (nested class) finders to the Post (nestee class)

Modify the views

Provide a link to the nested resource

What about the new/edit request.get? pattern? Is it “bad” to put additional methods on your RESTful controllers?
