allow(allowed_warnings = :all, if: true, &block) 連結
在區塊內允許先前已停用的方法停用警告。allowed_warnings
可以是包含字串、符號或正規表示式的陣列。(符號會當作字串處理)。這些字串會與區塊中產生的方法停用警告訊息進行比對。符合條件的警告將會被豁免在 ActiveSupport::Deprecation#disallowed_warnings
中所設定的規則之外。
選用的 if:
參數接受 true/false 值或是一個物件,該物件可以對 .call
進行回應。如果為 true,則會允許符合條件的警告。如果為 false,則方法會在不允許警告的情況下傳遞到區塊。
