用context控制many2one字段显示内容的问题

[jerry79]

定义了一个m2o字段，如下

<br /> #*.py<br /> &#039;partner_address_id&#039;: fields.many2one(&#039;res.partner.address&#039;, &#039;联系人&#039;,domain=&quot;[(&#039;partner_id&#039;,&#039;=&#039;,partner_id)]&quot;),<br /><br /> #*.xml<br />&lt;field name=&quot;partner_address_id&quot; context=&quot;{&#039;contact_display&#039;:&#039;name&#039;}&quot;/&gt;<br />

然后重新了res_partner_address的name_get函数，代码如下：

<br />def name_get(self, cr, user, ids, context=None):<br />&nbsp; &nbsp; &nbsp; &nbsp; if context is None:<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; context = {}&nbsp; &nbsp; &nbsp; &nbsp; <br />&nbsp; &nbsp; &nbsp; &nbsp; if not len(ids):<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; return &#91;]<br />&nbsp; &nbsp; &nbsp; &nbsp; res = &#91;]<br />&nbsp; &nbsp; &nbsp; &nbsp; for r in self.read(cr, user, ids, &#91;&#039;type_id&#039;,&#039;name&#039;,&#039;state_id&#039;,&#039;city&#039;,&#039;district&#039;,&#039;street&#039;,&#039;zip&#039;,&#039;partner_id&#039;]):<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if context.get(&#039;contact_display&#039;, &#039;contact&#039;)==&#039;partner&#039; and r&#91;&#039;partner_id&#039;]:&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; res.append((r&#91;&#039;id&#039;], r&#91;&#039;partner_id&#039;][1]))<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ################增加的代码<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; elif (context.get(&#039;contact_display&#039;,&#039;contact&#039;)==&#039;name&#039;) and r&#91;&#039;partner_id&#039;]:&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; res.append((r&#91;&#039;id&#039;],r&#91;&#039;name&#039;] or &#039;/&#039;))<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ################<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; else:&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;  <br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; # make a comma-separated list with the following non-empty elements<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; elems = [r&#91;&#039;type_id&#039;] and r&#91;&#039;type_id&#039;][1],r&#91;&#039;name&#039;],r&#91;&#039;state_id&#039;] and r&#91;&#039;state_id&#039;][1], r&#91;&#039;city&#039;], r&#91;&#039;district&#039;],r&#91;&#039;street&#039;],r&#91;&#039;zip&#039;]]<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; addr = &#039;, &#039;.join(filter(bool, elems))<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if (context.get(&#039;contact_display&#039;, &#039;contact&#039;)==&#039;partner_address&#039;) and r&#91;&#039;partner_id&#039;]:<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; res.append((r&#91;&#039;id&#039;], &quot;%s: %s&quot; % (r&#91;&#039;partner_id&#039;][1], addr or &#039;/&#039;)))<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; else:<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; res.append((r&#91;&#039;id&#039;], addr or &#039;/&#039;))<br />&nbsp; &nbsp; &nbsp; &nbsp; return res<br />

我现在就是希望在选择地址的时候，可以在不同的form中有不同的选项，如本文一开始定义的form的address字段，我希望下拉列表中只显示联系人的名称。修改name_get字段后，选择的时候确实只有联系人的名称，即这样代码的输出：
    res.append((r['id'],r['name'] or '/'))
但是当保存之后的显示内容却变成了这行代码的输出：
    res.append((r['id'], addr or '/'))

看上去似乎，保存的时候context失效了，因此执行到了else语句里面，我用log追踪了一下，确实如此，请问为什么会这样呢？
非常感谢！

尝试在这个视图的action 里面添加 context="{'contact_display':'name'}"

经过测试，在action那里加了context也不行。
