Rails supports this natively:
validates :phone, uniqueness: { scope: :name }
| def has_enough_inventory? | ||
| unless self.movie.available_inventory > 0 | ||
| errors[:quantity] << 'Not enough inventory for this rental' | ||
| end |

Nice work on this custom validation
| def self.find_checked_out_movie(movie_id, customer_id) | ||
| rental = Rental.where(movie_id: movie_id, customer_id: customer_id, check_in_date: nil) | ||
| return rental.empty? ? nil : rental.first | ||
| end |

Good use of model methods here. I might take it a step further and have something like Rental.checkout(movie_id, customer_id) and Rental.checkin(movie_id, customer_id), which encapsulate all of the work in one place. You could even wrap the whole thing in a transaction.
| def self.update_movie_and_customer(rental) | ||

|

| if rental.check_in_date.nil? | ||
| new_inventory = rental.movie.available_inventory - 1 |

This feels like it should be an instance method, since it requires an instance to run.

What if the movie doesn't have enough inventory left in stock?
| it "return bad request and error if the rental DNE" do | ||
| rental = rentals(:one) | ||
| rental_data = { | ||
| movie_id: rental.movie_id + 100, |

What about a rental that has already been checked in? What if there are multiple rentals for the same movie-customer pair?
| it "returns nil if the rental DNE" do | ||
| rental = rentals(:one) | ||
| movie_id = rental.movie_id + 100 | ||
| customer_id = rental.customer_id |
