when “display”
movies.each { |movie,rating| puts " #{movie}: #{rating}. "}

when “delete”

else

end

Why doesn’t the code work?

check the exact spacing

Still gives me this error: Oops, try again. Make sure to test your program by choosing ‘display’.

#4

Not really much of a mistake on your end, but I’d assume taking the full stop out at the end of the code should do it.

replace if movies[title.to_sym]==nil? with if movies[title.to_sym].nil?

#6

for the display part I used
when ‘display’
movies.each do |movie, rating|
puts “#{movie}: #{rating}”
end

I’m having a similar problem.
when ‘display’
movies.each do |movie, rating|
puts “#{movie}: #{rating}”
end

Even though it displays all the titles, I keep getting a message saying . It looks like your ‘puts’ doesn’t include back to the future: 10. (which is my first movie). Not sure where to go from here. I think my code is right?

#8

did you test it?
If you didn’t, you should test it out.

#9

i dont know how it help couse my code look just like yours, but ive copied/paste yours and got a green light…
weird…

#10

my issue was I had my do after |movie, rating| instead of before…

when “idiot”
puts “facepalm”

#11

did u fix it ? i have he same problem but i cant find the solution!

#12

I dont see any problem in your code … try checking for all correct spelling in the hash.

#13

Same here, my code looked exactly the same but only worked out when I copied/pasted the above one…

#14

movies = {
point_break: 4,
}
puts “What do you want to do?”
choice = gets.chomp

case choice
when “add”
puts “Please enter a movie title”
title = gets.chomp
if movies[title.to_sym] = nil
title = title.to_sym
else
puts “We already have that movie!”
end
puts “Please give a rating from 1 to 4.”
rating = gets.chomp
rating = rating.to_i
puts “#{title} has been added with a rating of #{rating}”
movies [title]= rating

when “update”
puts “What title do you want to update”
if movies[title] = nil
puts “There is no movie to update, silly!”
else
puts “What is the new rating to assign?”
rating = gets.chomp
rating = rating.to_i
end
puts “#{title} has been given a new rating of #{rating}”
when “display”
puts movies do |movie, rating|
puts “#{movie}: #{rating}”
end
when “delete”
puts “Deleted!”
else
puts “Error!”
end

My code displays point_break and its rating of 4. I am still not able to move forward. Any suggestions?

#15

I also have the same problem, but the first movie in my hash was indeed displayed in the window, did you find how to fix it?

#16

Your puts statement “#{title}: #{rating}.” should not include the period ‘.’

puts "#{title}: #{rating}"

will allow your movie to be printed exactly as requested by Codecademy.

same problem, any answer?!

#18

The code checker is very sensitive, I left a space between #{movie} and : should have been #{movie}:

#19

I have the same problem. the results looks correct but it still shows me an error!

#20

Would just confirm that the code checker is very sensitive. I put “Update” with a capital “U” and that was the reason why it wouldn’t let me pass. Once I changed the code to be while “update”, it worked.
I know it is not an answer to all the issues.
