Case statement with multiple values in each 'when' block

The best way I can describe what I'm looking for is to show you the failed code I've tried thus far:

case car
when ['honda', 'acura'].include?(car)
  # code
when 'toyota' || 'lexus'
  # code
end

I've got about 4 or 5 different when situations that should be triggered by approximately 50 different possible values of car. Is there a way to do this with case blocks or should I try a massive if block?

Solution

  • In a case statement, a , is the equivalent of || in an if statement.

    case Expression in Ruby

    case car
when 'toyota', 'lexus'
  puts 'brand is part of the Toyota Motor Corporation'
else
  puts 'some other brand'
end

# NOTE: You may use `then` after the when condition.
#       It is frequently used to place the body of the `when` on a single line.
case car
when 'toyota', 'lexus' then puts 'brand is part of the Toyota Motor Corporation'
else puts 'some other brand'
end
