Hey,
thank you for reading this post.
Why won't this work?
outer = func = ->(n) { outer << n } func[1]
=> 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. ms
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]
Oh, here’s with the new notation you’re using. Sorry about that.
self.outer =
func = → n { self.outer << n }
func[1]
Thank you very much for your answer. I did not mention that I am not using Rails in this case.
But the problem disappeared this morning - somehow.
