继承并重定义函数，执行时仍然执行父类函数的问题

[jerry79]

如下代码,此字段是父类已有的字段，子类中重新定义，同时重定义_amount_all函数，但是遇到了问题就是执行是仍然执行父类的_amount_all而不是子类重定义过的。
经过joshua的指点，问题出在属性multi上，这个属性表示多个字段共享一个function，因此需要将与此字段共享函数的其他字段也重定义一下，问题就可以解决。

<br />&#039;amount_total&#039;: fields.function(_amount_all, digits_compute= dp.get_precision(&#039;Sale Price&#039;), string=&#039;总计&#039;,<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; store = {<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &#039;sales.order&#039;: (lambda self, cr, uid, ids, c={}: ids, &#91;&#039;order_line&#039;], 10),<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &#039;sales.order.line&#039;: (_get_order, &#91;&#039;price_unit&#039;, &#039;product_uom_qty&#039;], 10),<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; },<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; multi=&#039;sums&#039;, help=&quot;The total amount.&quot;),<br />
