Ruby条件语句

Question

我的条件如下：

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

connection最初可能有nil值，因此我无法检查if connection && "name" == connection.name

如何有效地简化条件？

Answer 1

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

Answer 2

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