ruby if X is not equal to Y or Z then

I have the following:

a_disposition = [nil,'test','demo']

a_volume = a_disposition.count{|x| x != nil}

I want to count all values that are NOT nil and NOT 'test'. What is the ruby way of saying count where x is not nil and x is not 'test'? I am using ruby 2.0.

I think using the count method with a block is the cleanest way:

a_disposition.count{|x| !x.nil? && x != 'test'}

Another approach. It's not super performant, but it has nice functional touch. :)

a_disposition = [nil,'test','demo']

a_volume = a_disposition.reject(&:nil?).reject{|d| d == 'test'}.count # => 1
