使陈述依赖于其他陈述的顺序是一个好主意吗？ [英] Is it a good idea to make statements to depend on the order of other statements?

问题描述

我之前的问题，一个答案（ @Andy H ）说相关问题是陈述的顺序。那么，一般来说，是否具有前后语句依赖关系是正确/正确？例如，如果我有以下工作代码

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

以下代码不工作

class Article < ActiveRecord::Base      
  include MyModule

  acts_as_list ...
end

是否有一些不好的理由不继续执行该类？也就是说，一般来说，是一个好主意，使语句依赖于其他语句的顺序吗？

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?

推荐答案

我认为这不是好与坏的问题。

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

恰好是代码从上到下执行的情况。

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

因此，如果您在 statement_a 中有一些代码依赖于 statement_b添加的行为然后在之前放入 statement_b ，statement_a 是唯一的解决方案......

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...
