Saving hashes to file on Ruby

Question

I\'m just giving my first steps in programming. I have just finished another class in Code Academy. This time I was asked to create a small movie catalog. Here is my questio

Answer 1

The best way according to me is using Marshal method as explained here Marshaling The Marshal module dumps an object in a string, which can be written to a file. Reading the file and Marshal.Loading the string gives the original object. Writing to a file can be achieved using Marshal.dump

For example in your code this can be achieved using

movies = {
Memento: 3,
Primer: 4,
Ishtar: 1
}
# dumping:
File.open("test.marshal", "w"){|to_file| Marshal.dump(movies, to_file)}
# retrieving:
p File.open("test.marshal", "r"){|from_file| Marshal.load(from_file)}
#gives you movies = {Memento: 3,Primer: 4,Ishtar: 1}

Another method is explained by @Nick Veys using Yaml it is also used by people a lot.
