Dealing with common and uncommon problems with parsing CSV with Ruby

Ruslan Hassonov the approach with .each will load all records into memory and then allow you to access them - this can crash your application if the file is big. From the other side, .foreach goes through every line of the file without loading it into memory at once. It's similar to find_each method in Rails when you deal with many records.

Paweł Dąbrowski ah, being a Rails developer, I was only familiar with .find_each. Thanks!
