Ruby條件語句

Question

我的條件如下：

if connection
  if "name" == connection.name
    ...
  end
end

connection最初可能有nil值，所以我無法檢查if connection && "name" == connection.name

如何有效地簡化條件？

Answer 1

if connection and connection.name == "name"
   ...
end

Answer 2

unless connection.nil? || connection.name != "name"
  #...Statements
end
