Variable number of properties sent to Chef resource based off of recipe code

I want to pass a variable number of properties to a resource based off of the values that are available in the attributes.

Here is an idea of what I want to do. The if logic around the properties is what I am wanting but not sure if it is possible to do something like that...

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

Is there anything like this available in Chef?

You can do it using Ruby's send method, which invokes the method identified by the first argument, passing it any other arguments specified.

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
