No return value in rails console

A quick tip when working in rails console. If you're testing commands to run and don't want the console to output the return value, just append a semicolon to your ruby code.

# => [#<user:0x007fd72a408630> {:id => 1, :name => "Mr. T", ...}, tons and tons of other records]
# => nothing!

OK, so that's a contrived example, but this really comes in handy

  • when creating records, or 
  • if you need to update several records in one shot and don't want to see the return values, or
  • POSTing to an external API and avoiding all the cruft that comes in the response
