继承时如果使用了不同的名称能否使用视图继承

[tedi3231]

我有一个需求是这样的。一个朋友为一家连锁店装了很多摄像头，这些设备经常出问题，所以会有很多报修之类的东西处理，修好后也有一堆费用需要处理。因为各种不同的费用在填写的时候有许多字段都是一样的，我就想用继承了来实现，代码如下：

<br />class FeeBase(osv.osv):<br />&nbsp; &nbsp; &quot;&quot;&quot;<br />&nbsp; &nbsp; 费用基本类型,作为维护费用来使用<br />&nbsp; &nbsp; &quot;&quot;&quot;<br />&nbsp; &nbsp; _name=&quot;tms.feebase&quot;<br /><br />&nbsp; &nbsp; _columns={<br />&nbsp; &nbsp; &nbsp; &nbsp; &quot;processid&quot;:fields.char(string=&quot;ProcessId&quot;,size=100,required=False),&nbsp; &nbsp; &nbsp; &nbsp; <br />&nbsp; &nbsp; &nbsp; &nbsp; &quot;feedate&quot;:fields.date(string=&quot;Fee Date&quot;),<br />&nbsp; &nbsp; &nbsp; &nbsp; &quot;store_id&quot;:fields.many2one(&quot;tms.store&quot;,string=&quot;Store&quot;),<br />&nbsp; &nbsp; &nbsp; &nbsp; &quot;storenum&quot;:fields.related(&quot;store_id&quot;,&quot;name&quot;,type=&quot;char&quot;,string=&quot;Store Num&quot;),<br />&nbsp; &nbsp; &nbsp; &nbsp; &quot;province&quot;:fields.function(get_province_name,type=&quot;char&quot;,string=&quot;Province&quot;),<br />&nbsp; &nbsp; &nbsp; &nbsp; &quot;feetype_id&quot;:fields.many2one(&quot;tms.feetype&quot;,&quot;Fee Type&quot;),<br />&nbsp; &nbsp; &nbsp; &nbsp; &quot;payman&quot;:fields.many2one(&quot;res.users&quot;,&quot;Pay Man&quot;),<br />&nbsp; &nbsp; &nbsp; &nbsp; &quot;amount&quot;:fields.float(string=&quot;Amount&quot;),<br />&nbsp; &nbsp; &nbsp; &nbsp; &quot;accountamount&quot;:fields.float(string=&quot;Account Amount&quot;),<br />&nbsp; &nbsp; &nbsp; &nbsp; &quot;accountperiod&quot;:fields.char(string=&quot;Account Period&quot;, size=20,required=False),<br />&nbsp; &nbsp; &nbsp; &nbsp; &quot;oanum&quot;:fields.char(string=&quot;OA Num&quot;,size=100),<br />&nbsp; &nbsp; &nbsp; &nbsp; &quot;remark&quot;:fields.text(string=&quot;Remark&quot;),<br />&nbsp; &nbsp; &nbsp; &nbsp; &quot;state&quot;:fields.selection([(&quot;draft&quot;,&quot;Draft&quot;),(&quot;hasexported&quot;,&quot;Has Exported&quot;),(&quot;hasoa&quot;,&quot;Has Input OANum&quot;),(&quot;hasback&quot;,&quot;Has Back&quot;)],<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;  string=&quot;States&quot;),<br />&nbsp; &nbsp; }<br />

```
class FeeForSend(osv.osv):
    _inherit="tms.feebase"
    _name = "tms.feeforsend"

    _columns={
        "sendcompany":fields.many2one("tms.sendcompany","Send Company"),
        "sendordernum":fields.char(string="Send Order num",size=100,required=True),
        "sendproduct":fields.char(string="Send Product", size=200,required=True),
    }
```
```
class FeeForProductIt(osv.osv):
    _inherit="tms.feebase"
    _name = "tms.feeforproductit"

    _columns={
        "productname":fields.char(string="Product Name",size=200),
        "productprice":fields.float(string="Product Price"),
        "productcount":fields.integer(string="Product Count"),
        "accountproductprice":fields.integer(string="Account Product Price"),
        "accountproductcount":fields.integer(string="Account Product Count")
    }

FeeForProductIt()

class FeeForItService(osv.osv):
    _inherit="tms.feebase"
    _name = "tms.feeforitservice"

FeeForItService()
```
```
<record model="ir.ui.view" id="view_tms_feebase_tree">
            <field name="name">tms.feebase.tree</field>
            <field name="model">tms.feebase</field>
            <field name="type">tree</field>
            <field name="arch" type="xml">
                <tree string="维护费登记">
                    <field name="processid"/>
                    <field name="store_id" />
                    <field name="province"/>
                    <field name="storenum"/>
                    <field name="accountperiod"/>
                    <field name="feetype_id"/>
                    <field name="feedate"/>
                    <field name="payman"/>
                    <field name="amount" sum="Account" />
                    <field name="accountamount" sum="Account Amount"/>
<field name="state"/>
<field name="oanum"/>
                </tree>
            </field>
        </record>
```
从代码中可以看出每个子类与父类相差很小，在视图中只需要多添加几个字段或者完全不用添加。但当我使用视图的继承的机制时发现如果对象在继承时_name与父类不一样，视图是不能继承的。
有没有什么办法可以让我能够共用父类的视图？

有哪位大牛知道不？

_inherit 后就不要改名字了，用同一个model
加个 类别字段来区别不同的数据

Hi ccos,谢谢你的答复。如果不改名字我在使用的过程中遇到的问题是视图继承后会导致父类视图也发生变化。我希望在添加不同费用时显示不同的FORM。
