如何控制的数字控件按要求输入？

[pen2g]

在老肖的请假单上增加对天数的控制，当用户输入大于31天，我想提示错误并回写成30天，但提示后代码无法继续执行，即天数还是31天请教解决办法
py上增加的代码:

def onchange_qingjia_tians(self, cr, uid, ids, tians):<br />&nbsp; &nbsp; &nbsp;  if tians&gt;30:<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; raise osv.except_osv(_(&#039;Error !&#039;), _(&quot;不允许请假超过一个月.&quot;))<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; return {&#039;value&#039;:{&#039;tians&#039;:30}}

view.xml修改的代码:

<field name="tians" select="1" on_change="onchange_qingjia_tians(tians)"/>

校长云：
raise osv.except_osv
就是异常了，下面就不会执行return了

试试

<br /> warning = {<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &#039;title&#039;: _(&#039;Error!&#039;),<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &#039;message&#039;: _(&#039;不允许请假超过一个月.&#039;)<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }<br />return {&#039;value&#039;:{&#039;tians&#039;:30},&#039;warning&#039;: warning}<br />

感谢版主，解决了。不过答案少了个符号（在月字后)。正确的代码如下：

 warning = {<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &#039;title&#039;: _(&#039;Error!&#039;),<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &#039;message&#039;: _(&#039;不允许请假超过一个月.&#039;)<br />&nbsp; &nbsp; &nbsp;  }<br />&nbsp; &nbsp; &nbsp;  return {&#039;value&#039;:{&#039;tians&#039;:30},&#039;warning&#039;: warning}
