Congratulations! You're submitting your assignment!
If you didn't get to the functionality the question is asking about, reply with what you would have done if you had completed it.

Comprehension Questions

Question	Answer
Explain how you came up with the design of your ERD, based on the seed data.	We knew that movies and customers were disparate entities, and that in order to satisfy a many to many relationship, there needed to be a join table, stage left: rentals.
What would be the Big-O time complexity of your /customers & /movies endpoints? What does the time complexity depend on? Explain your reasoning.	O(n) linear time complexity where n represents the number of movies or customers.
What is the Big-O time complexity of the `POST /rentals/check-in` endpoint? What does the time complexity depend on? Explain your reasoning.	O(n) linear time complexity, where n represents the number of elements in the rentals collection.
Describe a set of positive and negative test cases you implemented for a model.	That due date can be set given valid rental data, and that it can't be set if rental data is invalid.
Describe a set of positive and negative test cases you implemented for a controller.	We tested that a rental can't be created without a valid movie or customer, and tested that it can be created with valid data.
How does your API respond when bad data is sent to it?	It displays a list of errors.
Describe one of your custom model methods and why you chose to wrap that functionality into a method.	We wrapped the set_available_inventory data in a model method. This method sets the available_inventory to the given inventory unless the user specifies a different availability in the HTTP request. We chose to do this in the model because the value of available_inventory relies upon the value given as the initial inventory.
Do you have any recommendations on how we could improve this project for the next cohort?	It would be helpful to have more context about how this particular API is intended to be used - user stories would have been super helpful. The smoke tests felt less like tests and more prescriptive in terms of how the data was structured, whereas the assignment felt like you had more control over how your API functioned. Also, the smoke tests for Wave 3 included optional requirements.

What We're Looking For

Feature	Feedback
Core Requirements
Git hygiene	Good number of commits and good commit messages
Comprehension questions	Check, you're welcome
General
Business Logic in Models	Somewhat, it would make sense to have a method to check out and check in a movie.
All required endpoints return expected JSON data	Required stuff done
Requests respond with appropriate HTTP Status Code	Check
Errors are reported	Check
Testing
Passes all Smoke Tests	All required tests pass
Model Tests - all relations, validations, and custom functions test positive & negative cases	Check, but you should have more model methods. What happens if you check in a movie that's not checked out, or check out a movie with not enough inventory.
Controller Tests - URI parameters and data in the request body have positive & negative cases	Check, you should also have some tests in the effects of checking in and checking out.
Overall	I'm not sure how to pluralize Amy (Amies?). You both hit the major learning goals. You did everything required. See my inline comments and let me know if you have any questions.

app/controllers/rentals_controller.rb

+class RentalsController < ApplicationController
+
+  def checkin
+    rental = Rental.find_by(customer_id: rental_params[:customer_id], movie_id: rental_params[:movie_id])


How is this changing the Rental status? There's no way to tell in the DB if the rental was checked in!

CheezItMan · 2019-05-23T23:13:00Z

app/models/customer.rb

@@ -0,0 +1,7 @@
+class Customer < ApplicationRecord
+  has_many :rentals
+


So no method to tell how many movies they have checked out.

CheezItMan · 2019-05-23T23:13:30Z

app/models/movie.rb

+  validates :overview, presence: true
+  validates :release_date, presence: true
+
+  def set_available_inventory


There are ways in Rails to invoke this method when a Movie is created, saved or updated.

CheezItMan · 2019-05-23T23:15:28Z

app/controllers/rentals_controller.rb

+    if rental
+      render json: {id: rental.id, movie_id: rental.movie.id, customer_id: rental.customer.id}, status: :ok
+    else
+      render json: [{errors: {rental: ["Rental not found for customer #{rental_params[:customer_id]}, and movie #{rental_params[:movie_id]}"]}}],


This line is a bit long, feel free to put in line breaks to make this more readable.

CheezItMan · 2019-05-23T23:15:37Z

app/controllers/rentals_controller.rb

+
+    if rental.save
+      rental.set_due_date
+      render json: [{ id: rental.id, movie_id: rental.movie.id, customer_id: rental.customer.id, due_date: rental.due_date }], status: :ok   


This line is also long. You also need to have some impact on the available inventories.
