如何在自己的模块创建记录后在消息模块产生动态？

[littlebo01]

销售模块创建销售订单的时候，会在消息模块下产生动态。我按照下面的方式尝试了也不行，可以在页面底部产生动态，在消息模块就不行。

<br /><br />inherit<br /><br />_inherit = &#91;&#039;mail.thread&#039;, &#039;ir.needaction_mixin&#039;]<br />for field you want to generate message add track_visibility=&#039;always&#039;<br /><br />_columns = {<br />&nbsp; &nbsp; &#039;tot_usr_fee&#039;: fields.float(&#039;Total User Fees&#039;, track_visibility=&#039;always&#039;),<br />}<br /><br />Then in view file add<br /><br />&nbsp; &nbsp; &lt;record id=&quot;mt_shipment_statement_invoice&quot; model=&quot;mail.message.subtype&quot;&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &lt;field name=&quot;name&quot;&gt;Custom Statement Invoice Generated&lt;/field&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &lt;field name=&quot;res_model&quot;&gt;shipment.statements&lt;/field&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &lt;field name=&quot;default&quot; eval=&quot;False&quot;/&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &lt;field name=&quot;description&quot;&gt;Invoice Generated&lt;/field&gt;<br />&nbsp; &nbsp; &lt;/record&gt;<br />&nbsp; &nbsp; &lt;record id=&quot;mt_shipment_statement_confirmed&quot; model=&quot;mail.message.subtype&quot;&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &lt;field name=&quot;name&quot;&gt;Custom Statement Confirmed&lt;/field&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &lt;field name=&quot;res_model&quot;&gt;shipment.statements&lt;/field&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &lt;field name=&quot;default&quot; eval=&quot;False&quot;/&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &lt;field name=&quot;description&quot;&gt;Invoice confirmed&lt;/field&gt;<br />&nbsp; &nbsp; &lt;/record&gt;<br />
