Unit 5 - Hackathon - dataset filter from multiple drop downs

Let me see if I can explain this…

One of the groups in my classroom, has created 3 drop downs (Rating, Type (movie, TV) and Country) and they are using the Netflix dataset. What they want to accomplish is being able to choose the rating (G, PG, PG-13, etc), the type (Movie, TV) and the country (Argentina, Bolivia, United States, etc.) and create a list of items from those filters. In other words, if they chose PG, Movie and United States, they would like to see a list of movies, showing in the United States that are all rated PG only. We can figure out a single drop down and filtering, but we can’t figure out how to tie them all together. We need help!

@troy Thanks for reaching out. It would be best to post link to the project and we could debug from there. Also please complete the information below.

and is your friend. If you can filter each then you can and the conditions together to get exactly what you want.

What I expect to happen: if they chose PG, Movie and United States, they would like to see a list of movies, showing in the United States that are all rated PG only.

What actually happens: What actually happens is that the program is filtering the first two columns, but is not filtering the “Rating”.

What I’ve tried: They’ve tried reordering the sequence of events, but to no avail.

Hmm, I’m not sure I understand the problem.

I added a loop at the end of your generate method to print out the rating and movie title of everything in Ratef after the filter has occurred. When I input PG, USA, Movies, I receive the following table:

"PG The Lake House"

When I spot check these movies, they look like they are all in fact PG. Are you sure the rating filter is not working? Based on my understanding of your design, the generate function is working as it should.

I do see some potential trouble in the updateScreen() function. I would have students review the idea of variables and scope, and also think about what it is that is actually being stored in the ratef array and how they can use it to access the name of the film.

Good luck,
