使用变量作为哈希键的twig

Is it possible to use the path function dynamically? With variables as parameters?

是否可以动态使用路径功能？用变量作为参数？

{{ path(nav.url, { nav.param_name : nav.param_value }) }}

{{path（nav.url，{nav.param_name：nav.param_value}）}}

Because if I try to use that code I am getting:

因为如果我尝试使用我得到的代码：

A hash key must be followed by a colon (:). 
Unexpected token "punctuation" of value "." 
("punctuation" expected with value ":")

I know by passing 'hardcoded' the param_name will work... like this:

我知道通过'硬编码'，param_name将起作用......就像这样：

{{ path('nav.url', { 'id' : nav.param_value }) }}

{{path（'nav.url'，{'id'：nav.param_value}）}}

However I need to pass the 3 value dynamically

但是我需要动态传递3值

The Twig book says you have to enclose expressions in parentheses to use them as keys, so maybe this will work:

Twig书说你必须在括号中包含表达式才能将它们用作键，所以这可能会起作用：

{{ path(nav.url, { (nav.param_name) : nav.param_value }) }}
