Question

以下是我需要做的事情

(Condition A and Condition B) or Condition C

(partner_id = partner_id **and** user_ids = context.get(uid)) **or** userid = 1

我尝试过的可能的域名过滤器是

domain="['|',('user_ids','=',1),'&',('partner_id','=',partner_id),('user_ids','=',context.get('uid'))]"

domain="['|','&',('partner_id','=',partner_id),('user_ids','=',context.get('uid')),('user_ids','=',1)]"

没有任何结果，我得到的错误在

之下

OpenERP ver 7 Domain filter with more conditions

附加说明 我找不到一个带有＆amp;的单域过滤器openerp source中的操作符。

我错过了什么吗？请建议。谢谢你的时间。

错误消息表明您的XML包含无效实体，即裸露的＆符号&字符。由于它是预定义的XML实体，因此必须将其作为&转义。

您在OpenERP源代码中找不到使用&的域名的原因是因为AND (&)运算符是默认运算符，因此在大多数情况下您可以完全省略它。由于逃避问题，这很方便。但是，当您组合OR / AND运算符时，可能需要这样做，因此您可以在高级安全规则中找到示例，这些规则也使用相同的域语法，例如here。

一般情况下，如果你想要(A and B) or C，你可以把它写成：

   ['|',C,'&',A,B]

表示您的XML文件应包含：

   ['|',C,'&amp;',A,B]

带有'＆amp;'的域名过滤器在openerp7中不起作用
