传递阵列

Question

我在设置布尔数组时遇到了一些问题。 我在我的模型定义的数组：

@Entity 
public class Ssr extends Model{ 

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

在我看来，文件我创建表

... 

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

... 

当我试图通过这个值，下一个画面，值不保存在SSR对象并且可以看到：

我应该使用List而不是数组吗？

感谢您的帮助。

我发现了酵母菌。如果您不需要将数组存储在数据库中，只需将“transient”关键字添加到变量声明中即可。

@Entity 
public class Ssr extends Model{ 

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