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 made a class for each file , and gave each class the attributes from the seed data. And we wrote the rest of the ERD based on the rest of the requirements.
Describe a set of positive and negative test cases you implemented for a model.	In the rental model test we checked that a rental could not be made if in that date range all movie copies are already rented. If there are enough copies on the available inventory then a rental can be made.
Describe a set of positive and negative test cases you implemented for a controller.	In the rental controller test we test that the checkin action can be made for a valid movie and customer id and that the rentals return date is set to today. The negative test case, the check in action responds with not found for movie ID and customer ID that DNE.
How does your API respond when bad data is sent to it?	It responds with not found when trying to perform an action on a record that does not exist. It responds with bad request when trying to create a new record with data that does not pass the validations.
Describe one of your custom model methods and why you chose to wrap that functionality into a method.	In the movie model we created get_available_inventory method to get the current number of available copies of a movie to be able to create a rental.
Do you have any recommendations on how we could improve this project for the next cohort?	Make the instructions for postman (smoketest) more clear/demo it in class.

Feature	Feedback
Core Requirements
Git hygiene	yes
Comprehension questions	yes
General
Business Logic in Models	some - Your `RentalsController` has a lot of business logic still.
All required endpoints return expected JSON data	yes
Requests respond with appropriate HTTP Status Code	yes
Errors are reported	yes
Testing
Passes all Smoke Tests	yes
Model Tests - all relations, validations, and custom functions test positive & negative cases	tests for many custom methods are missing, but otherwise looks good.

app/controllers/rentals_controller.rb

+
+    if rental.save
+      customer = Customer.find_by(id: customer_id)
+      customer.movies_checked_out_count += 1


All of this work around assigning dates, decreasing movies_checked_out_count, etc. should be encapsulated in one testable model method.

droberts-sea · 2018-05-18T00:22:13Z

app/controllers/rentals_controller.rb

+      if rental.save
+        customer = Customer.find_by(id: rental.customer_id)
+        customer.movies_checked_out_count -= 1
+        customer.save


Similarly, all this work ought to be wrapped up in one model method.

droberts-sea · 2018-05-18T00:22:30Z

app/controllers/rentals_controller.rb

+  def checkin
+    rental = Rental.find_by(movie_id: params[:movie_id], customer_id: params[:customer_id])
+
+    unless rental


What if this rental has already been returned?

droberts-sea · 2018-05-18T00:23:25Z

app/models/movie.rb

+  def get_available_inventory
+    checked_out_count = 0
+    self.rentals.each do |rental|
+      if rental.return_date.nil?


I like that you calculate this on the fly rather than saving it in the DB.

droberts-sea · 2018-05-18T00:24:13Z

app/models/rental.rb

+  def enough_inventory_for_rent
+    if movie
+      count = 0
+      self.movie.rentals.each do |rent|


How does this validation interact with returning movies?

droberts-sea · 2018-05-18T00:26:46Z

test/controllers/rentals_controller_test.rb

+
+    it "must respond with bad_request for a movie with no available inventory" do
+      movie = Movie.first
+      customer = Customer.first


droberts-sea · 2018-05-18T00:27:07Z

test/controllers/rentals_controller_test.rb

+
+    it "must respond with not_found for a rental that DNE" do
+
+      movie_id = Movie.last.id + 1


What if the rental has already been checked in

droberts-sea · 2018-05-18T00:27:49Z

test/models/customer_test.rb

+
+  end
+
+  describe "relationships" do


There are some custom methods you're not testing here.

droberts-sea · 2018-05-18T00:28:31Z

test/models/rental_test.rb

+
+    it "a rental can not be completed if all copies are rented for a date range" do
+      movie = Movie.first
+      customer = Customer.first


Good work getting a test in on this.
