在策略中正确授权它之后，我正在从树枝模板内部调用一个预先存在的对象中的方法：
{{ thisEmail.AddCC('[email protected]') }}
我的问题是我用来产生副作用的对象方法，而不是返回任何文本， ，这在我的模板输出中留下了可见的“ 1”。
如何删除此输出？我有一个工作：
{{ thisEmail.AddCC('[email protected]')|trim('1') }}
但是我觉得它并不完全优雅，只能消除该特定结果。我宁愿写 | nul 或 | drop 之类的东西，并使过滤器删除所有内容，而不管它以输入的方式收到了多少或什么样的东西。
我知道如何通过编写自己的树枝扩展过滤器来做到这一点，但是我的问题是：有一种很好的方法可以用核心的小树枝语言来实现这一目标，而不是延伸？
I am calling a method in a pre-existing object from inside a Twig template, after properly authorizing it in policy:
{{ thisEmail.AddCC('[email protected]') }}
My problem is that the object method, which I use to produce a side-effect, not to return any text, returns true, and that leaves a visible "1" in my template output.
How to remove this output? I have this one working:
{{ thisEmail.AddCC('[email protected]')|trim('1') }}
But I feel it's not entirely elegant, and it can only remove that specific result. I would prefer to write something like |nul or |drop and have the filter drop everything, regardless of how much or what kind of stuff it receives as input.
I know how to do it by writing my own Twig extension filters, but my question here is: is there a nice way of achieving this with the core Twig language, un-extended?

如果您想要
twig语句不要输出任何内容，则可以使用do标签，例如source
If you want a
twigstatement not to output anything you can use thedotag, e.g.source
