Question

After a my previous question, an answer (@Andy H) said that the related problem was the order of statements. So, in general, is it “correct” / “right” to have “before-after statement dependencies”? That is, for example, if I have the following working code

class Article < ActiveRecord::Base
  acts_as_list ...

  include MyModule
end

and the following code does not work

class Article < ActiveRecord::Base      
  include MyModule

  acts_as_list ...
end

Is there some “bad” reason to do not continue the implementation of the class? That is, in general, is that a good idea to make statements to depend on the order of other statements?

Answer 1

I think this is not a question of “good” vs “bad”.

It just happens to be the case that code gets executed from top down.

So if you have some code in statement_a that relies on behaviour added by statement_b then putting statement_b before statement_a is the only solution…
