This review focuses on creating ActiveRecord models with validations and and using nested forms. There are three steps each in their own branch. During the review we will move through each step and go over our answers:
- step1 asks you to create the necessary migrations for our models
- step2 asks you to add validations and associations
- step3 asks you to complete
app/views/orders/_form.html.erbas well as the related controller methods
Below is the README used throughout the exercise. Feel free to complete the app from scratch if you are looking for an extra challenge.
We are going to write a site to help a small store keep track of user orders. They need to work with three things: users, orders, and items.
-
customer will have a first name, a last name, and an email address. Every customer must have a first name and a last name and two customers could have the same name. A customer may not have an email address, but two customers cannot have the same email. A customer should be able to have many orders.
-
items must have a name, a description, and a price. The price must be a positive number, but might not be an integer (e.g. $12.99). No two items can have the same name and a description must be at least 10 words long.
-
orders must belong to exactly one customer and must have at least one item. Additionally, orders will have a status attribute, 'sent', which must be either true or false.
Users of our website should be able to:
- See a list of all orders.
- Create a new order. When creating a new order they should be able to:
- Choose from a list of preexisting items and/or create a new item on the same page.
- Choose from a list of preexisting customers or create a new customer on the same page.
- Edit an order.
- View all orders.
- Delete an order.
