有两个CLASS，第2个继承第1个的对象[color=red]service.type[/color]，但是第2个对象未在数据库中创建，是什么原因？_table如果加上是OK的，这里就有另外一个问题了，_name与_table相同时是可以省略的，这里为什么不给省略？

class eservice_type(osv.osv):&nbsp; &nbsp; <br />&nbsp;  _name = &#039;service.type&#039;<br />&nbsp; &nbsp; _table = &#039;bn_service_type&#039;&nbsp; &nbsp; <br />&nbsp; &nbsp; _columns= {<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;  &#039;description&#039;:fields.char(&quot;description&quot;, size=240, translate=True, help=&#039;&#039;)<br />&nbsp; &nbsp; &nbsp; &nbsp; }<br />&nbsp; &nbsp; _default={<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &#039;description&#039;:lambda *a:&#039;hello&#039;<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }<br />&nbsp; &nbsp; <br />eservice_type()<br /><br />class eservice_bn_lookup_types(osv.osv):<br />&nbsp;  <br />&nbsp; &nbsp; _name = &#039;bn.lookup.types&#039; <br />&nbsp; &nbsp; _inherit = &#039;service.type&#039;<br />&nbsp; &nbsp; _columns={<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;  &#039;meaning&#039;:fields.char(&quot;meaning&quot;, size=80, translate=True, help=&#039;&#039;)<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; <br />eservice_bn_lookup_types()

看这里： 设置->设置->序号与标示符->序列

并注意implementation字段将其改为：no gap（无间隔）

我试了还是不行的,我换个说法来表达我的意思.
