根据配方代码发送到 Chef 资源的可变数量的属性

Question

我想根据属性中可用的值将可变数量的属性传递给资源。

这是我想做的事情的想法。围绕属性的 if 逻辑是我想要的，但不确定是否可以做类似的事情...

rpms = [ 
  {
    "name": "name",
    "version": "version",
    "release": "release",
    "arch": "arch"
  },
  {
    "name": "name"
  }
]

rpms.each do | package_info |
  custom_package 'install' + package_info['name'] do
    name package_info['name']
    if defined?(package_info['version'])  # Only pass that property if it is available
      version package_info['version']
    end
    if defined?(package_info['release'])  # Only pass that property if it is available
      version package_info['release']
    end
    if defined?(package_info['arch'])  # Only pass that property if it is available
      version package_info['arch']
    end
  end
end

Chef 中有类似的东西吗？

Answer 1

您可以使用 Ruby's send method 执行此操作，它调用第一个参数标识的方法，将指定的任何其他参数传递给它。

rpms = [ 
  {
    "name": "name",
    "version": "version",
    "release": "release",
    "arch": "arch"
  },
  {
    "name": "name"
  }
]

rpms.each do |package_info|
  custom_package "install ${package_info['name']}" do
    package_info.each do |key, value|
      send(key, value)
    end
  end
end
