如何在继承的视图中有重复的field name的字段后添加新字段的方法

KevinKong

该问题是校长在给我们公司财务经理写的一个模块中出现的，目的是在供应商的“销售&采购“Tab页下面的供应商后面添加一字段，显示该供应商可供产品的类型。

下面是校长的代码：
partner.py

<br /># coding: utf-8<br />from osv import orm, fields<br /><br />class Partner(orm.Model):<br />&nbsp; &nbsp; _inherit = &#039;res.partner&#039;<br /><br />&nbsp; &nbsp; _columns = {<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &#039;product_categ_id&#039;: fields.many2one(&#039;product.category&#039;,<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; u&#039;供货类型&#039;),<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }<br /><br />

partner_view.xml:

<br />&lt;openerp&gt;<br />&nbsp; &nbsp; &lt;data&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &lt;record id=&quot;res_partner_view_supplier_product_categ&quot; model=&quot;ir.ui.view&quot;&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;field name=&quot;name&quot;&gt;res.partner.view.supplier.product_categ&lt;/field&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;field name=&quot;model&quot;&gt;res.partner&lt;/field&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;field name=&quot;inherit_id&quot; ref=&quot;base.view_partner_form&quot; /&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;field name=&quot;priority&quot; eval=&quot;20&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; &lt;xpath expr=&quot;//field[@name=&#039;supplier&#039;]&quot; position=&quot;after&quot;&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;field name=&quot;product_categ_id&quot;<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; attrs=&quot;{&#039;invisible&#039;: [(&#039;supplier&#039;, &#039;=&#039;, False)]}&quot;/&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;/xpath&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;/field&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &lt;/record&gt;<br />&nbsp; &nbsp; &nbsp; &lt;/data&gt;<br />&lt;/openerp&gt;<br />

问题来了，页面并没有如预期中的那样在‘供应商’后显示‘供货类型’。
我之前喜欢采用<field name="xxx" position='after'>的方式定位字段，自己尝试一下同样行不通。后来我把字段放在了“customer"后面，却能够正常的显示。。。

找res.partner模块的源码，发现问题：
res_partner_view.xml

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;/page&gt;<br />

发现在res_partner_view.xml文件中居然存在两个相同name的field，看来这就为什么字段不显示的原因了，个人猜想xpath
<xpath expr="//field[@name='supplier']" position="after">方式的定位只会定位第一个字段，
修改代码如下：

<br />&lt;openerp&gt;<br />&nbsp; &nbsp; &lt;data&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &lt;record id=&quot;res_partner_view_supplier_product_categ&quot; model=&quot;ir.ui.view&quot;&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;field name=&quot;name&quot;&gt;res.partner.view.supplier.product_categ&lt;/field&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;field name=&quot;model&quot;&gt;res.partner&lt;/field&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;field name=&quot;inherit_id&quot; ref=&quot;base.view_partner_form&quot; /&gt;<br />			&lt;field name=&quot;priority&quot; eval=&quot;40&quot;/&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;field name=&quot;arch&quot; type=&quot;xml&quot;&gt;<br />				&lt;xpath expr=&quot;/form/sheet/notebook/page[@string=&#039;Sales &amp;amp; Purchases&#039;]/group/group/field[@name=&#039;supplier&#039;]&quot; position=&quot;after&quot;&gt;<br />				&nbsp; &lt;field name=&quot;product_categ_id&quot; attrs=&quot;{&#039;invisible&#039;: [(&#039;supplier&#039;, &#039;=&#039;, False)]}&quot;/&gt;<br />				&lt;/xpath&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;/field&gt;<br />&nbsp; &nbsp; &nbsp; &nbsp; &lt;/record&gt;<br />&nbsp; &nbsp; &nbsp; &lt;/data&gt;<br />&lt;/openerp&gt;<br />

刷新页面，成功。
看来在用xpath定位字段的时候，最好还是把路径写全比较稳妥。

@KevinKong
这文章写的干净漂亮，多谢帮我修了bug。

这个invisible 的 supplier不知道是哪个模块加上去的。一个对象上的同样字段不应该在视图里出现两次的。

KevinKong

;D校长过奖了，还得多谢校长指点啦

我还有个问题想咨询一下，xpath 和 name 定位的方式有什么区别？哪个比较好呢？

rufeng1199

name 一般能唯一定位的话，用name就可以了，xpath则可以精确定位，依据DOM规则

digitalsatori

你其实已经发现了。
用字段名定位的方法，对某种情况下是无法处理的。必须用xpath
比如,要定位销售订单行上的name字段，用字段名定位就做不到了。
因为销售订单（sale.order)上有name字段，在order的视图里同样有订单行（sale.order.line)的name字段, 这就必须用xpath来定位了。
另外，xpath提供灵活定位方式可以通过相对路径定位到xml的任何一个节点，比如search view里的filter元素等等
象上面的例子也可以用下面这些方法定位：

&lt;xpath expr=&quot;//field[@name=&#039;customer&#039;]/field[@name=&#039;supplier&#039;]&quot; position=&quot;after&quot;&gt;

KevinKong

learned a lot & thanks a lot.

KevinKong

报告校长，代码

&lt;xpath expr=&quot;//field[@name=&#039;customer&#039;]/field[@name=&#039;supplier&#039;]&quot; position=&quot;after&quot;&gt;

还是行不通 :-\，好像customer跟supplier是并列的。

我试了一下，这样是可以的：

<br />xpath expr=&quot;//page[@string=&#039;Sales &amp;amp; Purchases&#039;]/group/group/field[@name=&#039;supplier&#039;]&quot; position=&quot;after&quot;&gt;<br />

digitalsatori

不好意思,试试下面的：

&lt;xpath expr=&quot;//field[@name=&#039;customer&#039;]/../field[@name=&#039;supplier&#039;]&quot; position=&quot;after&quot;&gt;

KevinKong

试了，好用

个人感觉应该跟linux中的cd ..差不多意思，先找到customer的父节点，然后在该父节点下找supplier。

明知道是两个，可以直接找第二个（或者叫最后一个的）
