通過紅寶石模型屬性到一個哈希和返回值

Question

我有婚姻狀況的哈希，它看起來像這樣...

marital_hash = {"Unknown" => "U", "Married" => "M", "Single" => "S", "Widowed" => "W", "Divorced" => "D", "Separated" => "S", "Civil Partner" => "C"} 

然後，我有一個用戶模型，其中有一個屬性：婚姻狀況。 marital_status的值與哈希中的鍵相同。我如何根據他們的：marital_status調用每個員工的哈希值？

Answer 1

marital_hash[user.marital_status]應該給你散列上適當的值。
