模型中的铁路自救
原标题:Ruby On Rails self saving in model

我的模式是,变化如下:

  def compare
        self.dirty = 1 if self.dirty == 0
        compare_recursive(0, MergeDigestTree.all)
        self.dirty = 0;
  end

我必须自称。 除此以外,或按此规定处以罚金。

最佳回答

你的问题有两个解释:

  • http://www.save。 <>strong>yes,因为特性分配并不对数据库做出改动。

  • 页: 1 <>/>。 它为改变案情而不予以挽救而 s。 我通常喜欢这样做,因为你给打电话者带来了更多的自由。

不管怎样,如何记录这种方法。

问题回答

你们必须拯救它,是。 尽管我看不出这一方法正在做些什么。

如果没有在这项职能范围内进行变革,在职能结束后的某个时候,你就不必呼吁这样做。

如果你在你看来能以人工方式重新利用这一职能......

resource.compare()
resource.save

如果你不想将<代码>本身.savein作为比较功能,将处以罚款。
