Rails Decal

Lecture 4 - Index, Show, New, Create

Logistics

So I messed up

• Resubmit HW 1 and 2
  • Your commits have a timestamp
• Extension on HW 3
• Always Backup your Production DB

Live Demo Heavy

Homework should contain all code

CRUD

• Create
• Read
• Update
• Destroy

Index

• Endpoint to create resource.  It is where the request gets sent.

Show

• Detail view of a particular resource

New

• Page to create new resource

Create

• A list of all the entries in the database table

Keep to resourceful routes!

Allows Rails to infer functionality

Strong Parameters

• Security Purposes
• Select certain key value pairs from your params hash
• Covered in live demo

form_for

• pass a model as an argument
• will infer route and method based on model passed
• sends form information scoped under model name

Paths

Convenient URL's in Ruby

Can see by running: rake routes
