Multiple Relationships practice with Ruby on Rails API.

Multiple Relationships in Rails

Objectives

1. Practice Active Record relationships
2. Create Migrationos, Models, and Controllers
3. Create connections through Models beyond join tables
4. Apply understanding of Active Record relationships

Instructions

Welcome to the life of a parent. If your kid has something, that means it is yours too. Your goal is to make a M:N Parent to Kid relationship -because a kid can have many parents, biological and otherwise. After that, make a 1:M relationhip between a kid and their toys. Finally, make a M:N relationship between a kid and the sports they play. By the end you should be able to call parent.toys and parent.sports to know what responsibilities you signed up for, through your kid.

Fork and clone to get started. Run bundle. Code away!

Part 1: Create the relationship between Parent and Kid

This is a M:N. Make the migrations, models, route, and controller. Seed at least 3 parents and 3 kids, then connect them. Make a GET request to /parents to see each parent and their kids. Use rails c or rails console to test your relationships before completing your controller.

Part 2: Create the relationship between Kid and Toy

This is a 1:M. Make the migration, model, and controller. Seed at least 3 toys. Make a GET request to /parents to see each parent, their kids, and the 'parents' toys. Use rails c to test your relationships -you should be able to run kid.toys and parent.toys.

Part 3: Create the relationship between Kid and Sport

This is a M:N. Make the migrations, models, and controller. Seed at least 3 sports, then connect them to kids. Make a GET request to /parents/ to see each parent, their kids, the 'parents' toys, and the 'parents' sports. User rails c to test your relationships -you should be able to run kid.sports and parent.sports.

Tips

• Going through a model to make a relationship can be used for more than pure join tables.
• rails c or rails console is your best friend for testing relationships before moving past your migrations and seeds.
• You'll need to use include in your controller.

Bonus

All the following will require more code:

• Use Postman to create a new Toy.
• Use Postman to create a new Kid and Toy in the same request. (This will require accepting nested attributes).
• Use Postman to connect a kid to an existing sport they are NOT already connected to.
