与Rails3同时插入多行

Question

We have an existing mysql database and a php front end which we're currently porting to a RoR3 application using Datamapper.

We need to insert multiple rows with a single commit, each using the same name. For example, if I look at the groups table, we have this structure:

+-----------+------------------+------+-----+---------+----------------+
| Field     | Type             | Null | Key | Default | Extra          |
+-----------+------------------+------+-----+---------+----------------+
| id        | int(11) unsigned | NO   | PRI | NULL    | auto_increment |
| groupname | varchar(64)      | NO   | MUL |         |                |
| attribute | varchar(64)      | NO   |     |         |                |
| op        | char(2)          | NO   |     | ==      |                |
| value     | varchar(253)     | NO   |     |         |                |
+-----------+------------------+------+-----+---------+----------------+

And the content looks like this:

+----+---------------------------+-------------------+----+------------+
| id | groupname                 | attribute         | op | value      |
+----+---------------------------+-------------------+----+------------+
|  1 | RADIUS-Disabled-Users     | Auth-Type         | := | Reject     |
|  2 | 30-minutes                | Huntgroup-Name    | == | xxx        |
|  3 | 30-minutes                | Simultaneous-Use  | := | 1          |
|  4 | 30-minutes                | Max-Daily-Session | := | 1800       |
|  7 | silver                    | Simultaneous-Use  | := | 25         |
+----+---------------------------+-------------------+----+------------+

As you can see, we have multiple rows with the same name, each with a different attribute and value.

In our view, I need a name field followed by a drop down menu for the attribute and a field for the value. Most importantly we need to be able to insert multiple rows in one move.

Can anyone point me in the right direction?
