傳遞陣列

Question

我在設置布爾數組時遇到了一些問題。 我在我的模型定義的數組：

@Entity 
public class Ssr extends Model{ 

    @Id 
    public int num; 
    public boolean[] row1; 

在我看來，文件我創建表

... 

<td>Network</td>   
    @for(a <- 1 to 10){ 
     <td> 
    @checkbox(ssrForm("row1[@a]"),'_label->None) 
    </td> 
    } 

... 

當我試圖通過這個值，下一個畫面，值不保存在SSR對象並且可以看到：

我應該使用List而不是數組嗎？

感謝您的幫助。

我發現了酵母菌。如果您不需要將數組存儲在數據庫中，只需將「transient」關鍵字添加到變量聲明中即可。

@Entity 
public class Ssr extends Model{ 

    @Id 
    public int num; 
    public transient boolean[] row1;
