You can do it only if you parse the resulting yml file as an erb template:
只有在将生成的yml文件解析为erb模板时，才能执行此操作：
YAML.load(ERB.new(File.read("myfile.yml")).result)
result method passes the current binding into template and renders the file according to the variables in the scope.
result方法将当前绑定传递给模板，并根据范围中的变量呈现文件。
Here's an article about such experiments.
