Rails Practice Challenge - Gym

Setup

To download the dependencies for backend, run:

$ bundle install

There is some starter code in the db/seeds.rb file so that once you've generated the models, you'll be able to create data to test your application. You can run your Rails API on localhost:3000 by running:

$ rails s

There are no tests for this application, so you'll need to check your progress by running the server and using Postman to make requests.

Introduction

We're going to build an app for a Gym create the following database structure. You will have three models (and their corresponding tables), Gym, Client and Membership, with the following relationships:

• A client has many gyms and has many memberships
• A gym has many clients and has many memberships
• A membership belongs to a gym and belongs to a client

Migrations

Write migrations to create the following tables:

Gyms Table:

id	name	address
1	L.A.Fitness	Suite 981 1795 Leida Fords, Nataliemouth, TN 14377-4979
2	Planet Fitness	7768 David Avenue, Greenside, PA 67475-3655

Clients Table:

id	name	age
1	Casie Effertz	18
2	Dorris Bogan	52
3	Bernie Schiller	44
4	Manie Dare	29

Memberships Table:

id	gym_id	client_id	charge
1	1	1	40
2	1	2	40
3	2	1	50
4	2	3	60

Deliverables

It may be helpful to write a list of the routes you'll need before you begin.

A user should be able to:

• Create a new membership

  • New membership require a gym_id, client_id, and membership charge.
  • Validation: A client can have only one membership with gym

• View one specific gym

  • if Gym exists, return JSON data for the gym
  • else return error with a status code

• Delete a gym

  • If the Gym exists, it should be removed from the database, along with any Memberships that are associated with it (a Membership belongs to a Gym, so you need to delete the Memberships before the Gym can be deleted).

    After deleting the Gym, return an empty response body, along with the appropriate HTTP status code.

    If the Gym does not exist, return the following JSON data, along with the appropriate HTTP status code:

    {
      "error": "Gym not found"
    }

• View one specific client

  • if Client exists, return JSON data for the Client
  • else return error with a status code

Bonus

• On client show route, send response that includes total amount for all membership for that client.
• Create index and update routes for gym and client
