Video StoreWhat We're Looking For
Great work overall you two! In general, great work on creating this API. The code could be tidied up in some parts, but it's overall good. I like your model and controller tests a lot, too. I'm adding a few comments, but overall: well done PS: This project lists Ruby 2.4.1 as a dependency even though we've been working in 2.5.1. Just curious? |

You end up assigning the result of movie.save_available_inventory(avail) into the variable result, but you don't use result anywhere... you probably don't need to assign this variable to anything

| result = movie.save | ||
| if result | ||
| movie_id = movie.id |

Same as above: No need to make the movie_id variable here
| if rental.save | ||
| inventory = movie.calculate_available_inventory() | ||
| movie.save_available_inventory(inventory) | ||
| customer[:movies_checked_out_count] += 1 |

Could you make a method that increments the customer's checked out count field instead of operating on it directly here?
| validates :movie_id, presence: true | ||
|
|
||
| def checked_out?() | ||
| return self.checkedout == true |
There was a problem hiding this comment.
because of the nature of this conditional, you could probably just return self.checkedout
| rental = Rental.new(rental_params) | ||
| if rental.save | ||
| inventory = movie.calculate_available_inventory() | ||
| movie.save_available_inventory(inventory) |

The two above lines are tightly coupled/repeated a lot. Could there be a method on Movie so an instance of Movie can update its available inventory itself?
| body = JSON.parse(response.body) | ||
| expect(body).must_be_kind_of expected_type | ||
| return body | ||
| end |

Nice! This looks really slick! I really like this default argument!
| body = JSON.parse(response.body) | ||
| expect(body).must_be_kind_of expected_type | ||
| return body | ||
| end |
There was a problem hiding this comment.
Since this helper method is in multiple files, you could probably bring it out into the test_helper file
| expect(body).must_include "errors" | ||
|
|
||
| must_respond_with :success | ||
| end |
