在crm模块的商机那里增加历史记录

[jerry79]

CRM模块中的商机，有一个History的tab页面，但是其中能够显示的似乎只有email的历史记录（这一点还没测试，只是从界面和代码中做的推测），我想将所有与这个商机相关的meeting的历史记录显示出来，还想自定义一个历史记录，就是手动添加一个Note,然后采用tree view的形式显示出来（商机界面有一个add internal note，很奇怪，增加之后没有任何反应）。但是现在增加meeting的历史记录有点问题，特来请教：
我的PY文件：

<br />from osv import fields,osv<br />class crm_opportunity(osv.osv):<br />&nbsp; &nbsp; &quot;&quot;&quot; CRM Opportunity Case &quot;&quot;&quot;<br />&nbsp; &nbsp; _name = &quot;crm.lead&quot;<br />&nbsp; &nbsp; _inherit = &#91;&#039;crm.lead&#039;]<br />&nbsp; &nbsp; _columns = {<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &#039;meeting_ids&#039;: fields.one2many(&#039;crm.meeting&#039;, &#039;partner_id&#039;,\<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;  &#039;Meetings&#039;),<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;  }<br />crm_opportunity()<br />

我的View文件：

<br />&lt;record id=&quot;crm_case_form_view_oppor_extend&quot; model=&quot;ir.ui.view&quot;&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;field name=&quot;name&quot;&gt;Opportunities&lt;/field&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;field name=&quot;model&quot;&gt;crm.lead&lt;/field&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;field name=&quot;type&quot;&gt;form&lt;/field&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;field name=&quot;inherit_id&quot; ref=&quot;crm.crm_case_form_view_oppor&quot;/&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;field name=&quot;arch&quot; type=&quot;xml&quot;&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;  <br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;field name=&quot;message_ids&quot; position=&quot;before&quot;&gt;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;  <br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;field name=&quot;meeting_ids&quot; colspan=&quot;4&quot; nolabel=&quot;1&quot;&nbsp; context=&quot;{&#039;default_partner_id&#039;: active_id}&quot;&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;tree string=&quot;Meetings&quot; colors=&quot;gray:state in (&#039;draft&#039;, &#039;cancel&#039;,&#039;done&#039;,&#039;pending&#039;)&quot;&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;field name=&quot;user_id&quot; string=&quot;Responsible&quot;/&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;field name=&quot;name&quot; string=&quot;Subject&quot; /&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;field name=&quot;date&quot; string=&quot;Start Date&quot; /&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;field name=&quot;date_deadline&quot; string=&quot;End Date&quot;/&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;/tree&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;/field&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;/field&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;/field&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &lt;/record&gt;<br />

结果增加meeting的历史记录的view成功了，但是却显示不了历史记录，如附件，是商机和客户信息的图片。我是参考crm模块中的res_partner.py和相应的view来做的，为什么显示不出历史记录呢。
谢谢
