紅寶石條件語句

Question

我有這樣一個條件：

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

connection可能有nil值開始，所以我不能夠檢查if connection && "name" == connection.name

我怎樣纔能有效地簡化條件？

Answer 1

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

Answer 2

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