Ruby/Rails - Get the last two values in an array

@numbers = [ 1, 2, 3, 4, 5, 6, 7, 8 ]

@numbers.last will give me 8

I need to grab the last two records. So far I've tried this, however it throws a NoMethodError:

@numbers.last - 1

last takes an argument:

@numbers = [ 1, 2, 3, 4, 5, 6, 7, 8 ]
@numbers.last(2) # => [7,8]

If you want to remove the last two items:

@numbers.pop(2) #=> [7, 8]
p @numbers #=> [1, 2, 3, 4, 5, 6]

Arrays are defined using [] not {}. You can use negative indices and ranges to do what you want:

>> @numbers = [ 1, 2, 3, 4, 5, 6, 7, 8 ] #=> [1, 2, 3, 4, 5, 6, 7, 8]
>> @numbers.last #=> 8
>> @numbers[-2..-1] #=> [7, 8]
