[Rails] Re: Why won't this lambda thing work?

Are you doing this in the model, and is outer a member variable? If so, did you forget to use self on it?

self.outer = []

func = lambda { |n| self.outer << n }

func[1]

Hey,

thank you for reading this post.

outer = []
func = ->(n) { outer << n }

=> outer stays empty. Why that? Since outer is readable in the lambda
function it should be changeable as it is the same instance of the
array. I am a bit confused.

Thanks you very much for your answers.
