[Rails] Re: Compare hashes and report where the change was

Ruby on Rails Wednesday, April 11, 2018

If you want to get what is the difference between two hashes, you can do this:


result = {}  hash1.each {|key, value| result[key] = hash2[key] if hash2[key] != value }  puts result 

or use a this hash1.to_a == hash2.to_a turning it to an array and compairing those. or you could use to_s compare strings.
