Reflection

Prompt	Response
Explain how you came up with the initial design of your ERD, based on the seed data and reading through the API endpoints	We organized our ERD by looking at the requirements (endpoints) and thinking about how the different models should interact with each other. For Rental, we thought about the associations and whether or not it needed to be a Model of its own.
What would be the Big-O time complexity of your /customers & /videos endpoints? What does the time complexity depend on? Explain your reasoning.	Index: O(n); listing all customer and video items; show: O(n); assuming find_by is a linear search; Create: O(1)?
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) to find the correct rental with the passed in customer and video ids.
Describe a specific set of positive and negative test cases you implemented for a model.	Positive: all required fields are present; negative: missing a required field
Describe a specific set of positive and negative test cases you implemented for a controller.	JSON we render when something exists vs doesn't exist
Broadly, describe how an API should respond when it handles a request with invalid/erroneous parameters.	Render JSON error message and appropriate status code
Describe one of your custom model methods and why you chose to wrap that functionality into a method.	We added custom model methods to Rental so that pieces that go under a specific theme fall together and the controller code is easier to read. (ex. initialize_rental, rental_checkin, is_valid?)
