This available_inventory makes better sense as a method instead of as a field. That way you don't have to engage in this chicanery.
Instead I suggest putting available_inventory method and movies_checked_out_count as methods in movie.rb and customer.rb.

You should also test the required keys.

What about checking out a movie with no available inventory left?
| end | ||
|
|

| describe "check-in" do | ||
| let(:checkin_params) { |

What if you check in a movie that's not checked out?
| if !customer | ||
| render json: { "errors": { "customer": ["Customer not found"] } }, status: :bad_request | ||
| else | ||
| checkout_date = Date.today |

Look at how much code is here... This would indicate a good case for a model method.
| rental = Rental.find_by(customer_id: rental_params[:customer_id], movie_id: rental_params[:movie_id]) | ||
|
|
||
| if rental | ||
| rental.movie.available_inventory += 1 |

This business logic would look lovely in a model.
