For this assessment, you'll be working with a Pizza Restaurant domain.
In this repo, there is a Rails application with some features built out. There is also a fully built React frontend application, so you can test if your API is working.
Your job is to build out the Rails API to add the functionality described in the deliverables below.
To download the dependencies for the frontend and backend, run:
bundle install
npm install --prefix client
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
You can run your React app on localhost:4000
by running:
npm start --prefix client
You are not being assessed on React, and you don't have to update any of the React code; the frontend code is available just so that you can test out the behavior of your API in a realistic setting.
There are also tests included which you can run using rspec
to check your work.
Depending on your preference, you can either check your progress by:
- Running
rspec
and seeing if your code passes the tests - Running the React application in the browser and interacting with the API via the frontend
- Running the Rails server and using Postman to make requests
You need to create the following relationships:
- A
Restaurant
has manyPizza
s throughRestaurantPizza
- A
Pizza
has manyRestaurant
s throughRestaurantPizza
- A
RestaurantPizza
belongs to aRestaurant
and belongs to aPizza
Start by creating the models and migrations for the following database tables:
If you use a Rails generator to create the models, make sure to use the
--no-test-framework
flag to avoid overwriting the test files.
Add any code needed in the model files to establish the relationships.
Then, run the migrations and seed file:
rails db:migrate db:seed
If you aren't able to get the provided seed file working, you are welcome to generate your own seed data to test the application.
Add validations to the RestaurantPizza
model:
- must have a
price
between 1 and 30
Set up the following routes. Make sure to return JSON data in the format specified along with the appropriate HTTP verb.
Return JSON data in the format below:
[
{
"id": 1,
"name": "Sottocasa NYC",
"address": "298 Atlantic Ave, Brooklyn, NY 11201"
},
{
"id": 2,
"name": "PizzArte",
"address": "69 W 55th St, New York, NY 10019"
}
]
If the Restaurant
exists, return JSON data in the format below:
{
"id": 1,
"name": "Sottocasa NYC",
"address": "298 Atlantic Ave, Brooklyn, NY 11201",
"pizzas": [
{
"id": 1,
"name": "Cheese",
"ingredients": "Dough, Tomato Sauce, Cheese"
},
{
"id": 2,
"name": "Pepperoni",
"ingredients": "Dough, Tomato Sauce, Cheese, Pepperoni"
}
]
}
If the Restaurant
does not exist, return the following JSON data, along with
the appropriate HTTP status code:
{
"error": "Restaurant not found"
}
If the Restaurant
exists, it should be removed from the database, along with
any RestaurantPizza
s that are associated with it (a RestaurantPizza
belongs
to a Restaurant
, so you need to delete the RestaurantPizza
s before the
Restaurant
can be deleted).
After deleting the Restaurant
, return an empty response body, along with the
appropriate HTTP status code.
If the Restaurant
does not exist, return the following JSON data, along with
the appropriate HTTP status code:
{
"error": "Restaurant not found"
}
Return JSON data in the format below:
[
{
"id": 1,
"name": "Cheese",
"ingredients": "Dough, Tomato Sauce, Cheese"
},
{
"id": 2,
"name": "Pepperoni",
"ingredients": "Dough, Tomato Sauce, Cheese, Pepperoni"
}
]
This route should create a new RestaurantPizza
that is associated with an
existing Pizza
and Restaurant
. It should accept an object with the following
properties in the body of the request:
{
"price": 5,
"pizza_id": 1,
"restaurant_id": 3
}
If the RestaurantPizza
is created successfully, send back a response with the data
related to the Pizza
:
{
"id": 1,
"name": "Cheese",
"ingredients": "Dough, Tomato Sauce, Cheese"
}
If the RestaurantPizza
is not created successfully, return the following
JSON data, along with the appropriate HTTP status code:
{
"errors": ["validation errors"]
}
