请教，@api.multi def write(self, vals): 返回{'warning': warning}，无效？？

[lipeng260]

在@api.onchange中可以，在这里为什么不行，请教。

@api.multi<br />&nbsp; &nbsp; def write(self, vals):<br />&nbsp; &nbsp; &nbsp; &nbsp; parent_id = self.search([(&#039;id&#039;, &#039;=&#039;, vals&#91;&#039;parent_id&#039;])])<br />&nbsp; &nbsp; &nbsp; &nbsp; def check(self, id):<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if(self.parent_id):<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; return check(self.parent_id, id) and id != self.id<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; else:<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; return id != self.id<br />&nbsp; &nbsp; &nbsp; &nbsp; if check(parent_id, self.id):<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; return super(classify, self).write(vals)<br />&nbsp; &nbsp; &nbsp; &nbsp; else:<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; warning = {<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &#039;title&#039;: &quot;Warning!&quot;,<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &#039;message&#039;: &quot;the available num Can&#039;t be more than the num&quot;,<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; return {&#039;warning&#039;: warning}

为什么不是用raise 呢。事务会回滚的。
