Last updates on the GreenBox and tests to be added and updated this afternoon.

Overall pretty good waves 1-2.

You do need more work on available_movies and rent_movie and the tests.

You have a good number of commits and good commit messages and the code is overall pretty well done. I'd like you to first look through the MovieReserver class and the two incomplete methods and then work on the tests with Andrew if you can.

lib/date_range.rb

+      if (date >= @start_date) && (date < @end_date)
+        return true
+      else
+        date < @start_date || date >= @end_date


You don't need this 2nd conditional since if it's not inside you can return false.

if (date >= @start_date) && (date < @end_date) return true else return false end

CheezItMan · 2018-09-10T19:45:35Z

lib/date_range.rb

+
+
+# `overlaps(other_date_range)` - This method takes another date range as a parameter and returns `true` if the date ranges overlap.
+    def overlaps(other_date_range)


CheezItMan · 2018-09-10T19:45:58Z

lib/movie.rb

+      @actors = actors
+    end
+
+    movie = GreenBox::Movie.new(4,'Happiness','Fox',actors:['Denzel Washington', 'LL Cool J'])


You can take this line out

CheezItMan · 2018-09-10T19:46:43Z

lib/movie_reserver.rb

+    def initialize
+      @movies = MovieReserver.load_movies
+      @rentals = []
+      @date_range = GreenBox::DateRange.new(Time.parse('2018-08-08'),Time.parse('2018-08-09'))


This @date_range is unnecessary since there isn't one daterange needed by the system. Instead each Rental will have it's own DateRange

CheezItMan · 2018-09-10T19:47:33Z

lib/movie_reserver.rb

+        publisher = line[2]
+        all_actors = line[3]
+        actors_names = all_actors.split(':')
+        actors = {actors: actors_names}


You could also make this:

actors = actors_names

And just use an array instead of a has containing one array.

CheezItMan · 2018-09-10T19:48:21Z

lib/movie_reserver.rb

+      # them with the ones in the movie list
+      #
+
+      if @rentals.length > 0


Since you have the previous if statement, you don't need this one.

CheezItMan · 2018-09-10T19:50:42Z

lib/movie_reserver.rb

+        @rentals.each do |movie|
+          movie.id
+          if @movies.include(movie.id)
+          available_movies = @movies.delete(movie.id)


Since delete will remove any matching movies from the@movies array permanently, you would do better to:

Make a copy of @movies

Use .reject to remove movies that match the given id

Return that resulting list of movies

CheezItMan · 2018-09-10T19:51:13Z

lib/rental.rb

+    end

+# *   `cost`:  This method will return the cost of the rental.  A movie rental will cost $3.0 per night.  The customer is **not** charged for the day the movie is checked in.  So a movie checked out on August 8th and checked in August 10th would cost $3.00 * 2 days = $6.00
+    def cost


CheezItMan · 2018-09-10T19:52:50Z

specs/movie_reserver_spec.rb

+    it 'will not include rented movies' do
      date_range = GreenBox::DateRange.new(Time.parse('2018-08-08'), Time.parse('2018-08-09'))
-      reserver.rent_movie('Crazy Rich Asians', date_range, 'Ada Lovelace')
+      #reserver.rent_movie('Crazy Rich Asians', date_range, 'Ada Lovelace')


If you're going to comment this out, you'll need to manually add a rented movie to the system.

reserver.rentals << Rental.new('movie title', Time.parse('2018-08-08'), Time.parse('2018-08-09'))

CheezItMan · 2018-09-10T19:53:57Z

specs/movie_reserver_spec.rb

+      # assert
+          ## the rent_movie methods will return
+
+      @rental.rent_movie(id = 3)


It might be easier just to give the title of the movie, although you could do it by ID. However you'll need a MovieReserver instance.

You are right these tests below need work. You might try replicating some of the format of the tests written for you.

…nt_movies and available_movies

… 2 test failrures and 1 test error

CheezItMan

I left a few more suggestions here, your tests are not bad, and they are catching some bugs in your code.

Some strong improvement here.

CheezItMan · 2018-09-13T03:24:44Z

specs/movie_reserver_spec.rb

-    xit 'cannot rent a movie already rented' do
-      # TODO Your Code goes here

+    it 'cannot rent a movie already rented' do


This is a well written test! 👍

Nice work!

CheezItMan · 2018-09-13T03:26:55Z

lib/movie_reserver.rb

+    # *   `rent_movie(movie_title, date_range, customer_name)`:  This method will attempt to reserve a movie with the given title for the given date range.  If the movie is not available in that range the method should raise a `StandardError`.
+
+    def rent_movie(movie_title, date_range, customer_name)
+      @movies.each do |movie|


As your test shows, this isn't working because it always rents a movie as long as the movie is in the inventory.

If I can make a suggestion:

See if the list of available_movies has this movie title, you can use .each or find_by to do so.

If so, you can create a rental,

add it to the list

return the rental

CheezItMan · 2018-09-13T03:29:35Z

specs/movie_reserver_spec.rb

+
+      #Assertions - something that has changed that tells
+      #us we have the expected result
+      expect(rental).wont_be_nil


This is good, you also might want to test that
expect(rental.movie.title).must_equal title (the title of the movie being rented is right.

You can also test that the number of rentals has increased by one (so the length of rentals increased by one).

CheezItMan · 2018-09-13T03:30:58Z

specs/movie_reserver_spec.rb

    it 'can rent multiple movies with the same title' do
-      # TODO Your Code goes here

+      movie_reserver  = GreenBox::MovieReserver.new


Nicely done!

CheezItMan · 2018-09-13T03:40:59Z

lib/movie_reserver.rb

+          # @movies is a MovieReserver object that contains movies.
+          available_movies = []
+          @movies.each do |movie|
+            if @rentals.date_range == date_range


This part is not quite right. @rentals is an array and so doesn't have a date_range attribute.
Instead you should:

make a copy of the movies list

then loop through your rentals array and remove any movies who have a rental that conflicts.

You can look up the select method to find movies that don't have a given ID or object id.
