Stop Rails Console from barfing a ton of data

Posted by adriandz on September 21, 2010 — 6 comments
When you use Rails' console for stuff like this:

people.each { |person| puts person.name }

You'll notice that first you get the names of people like you wanted, but then console barfs out the array of everything you are iterating through, in this case all of the people. Make it stop.

“” I've also been known to use ';0'. E.g.:

people.each { |person| puts person.name };0Brad - September 21, 2010 13:43

“” I have always done people.each { |person| puts person.name }; nil

This is great on heroku console as well.Knodi - September 21, 2010 15:43

puts people.map(&:name)

is a better shortcut.PaulMcMahon - September 22, 2010 04:14
