为我的 attrs 属性创建复杂的域 [英] create complicated domain for my attrs attribute

问题描述

我想为我的 attrs 构建以下逻辑.有人可以帮我吗?

 A OR B OR ( C OR ( (D AND E) OR (F AND G AND H) ) )

我尝试了以下逻辑

['|','|', (A), (B),'|'(C), '|','&', (D), (E),'&', (F),'&'(G),(H)]

解决方案

形成这样的域可能非常棘手.在这些情况下，您可以使用 odoo.osv.expression 助手，它接受域列表(不是叶子列表).示例:

<预><代码>>>>从 odoo.osv.expression 导入 AND, OR>>>a,b,c,d,e,f,g,h = ([("field_" + x, "=", "value_" + x)] for x in "ABCDEFGH")>>>OR([a, b, OR([c, AND([d, e]), AND([f, g, h])])])['|', '|', ('field_A', '=', 'value_A'), ('field_B', '=', 'value_B'), '|', '|', ('field_C','=', 'value_C'), '&', ('field_D', '=', 'value_D'), ('field_E', '=', 'value_E'), '&', '&', ('field_F', '=', 'value_F'), ('field_G', '=', 'value_G'), ('field_H', '=', 'value_H')]

注意:我必须将您的变量转换为有效的域，否则这些方法将不起作用.

I want to build below logic for my attrs . Can some help me here ?

 A OR B OR ( C OR ( (D AND E) OR (F AND G AND H) ) ) 

I tried with below logic

['|','|', (A), (B),'|'(C), '|','&', (D), (E),'&', (F),'&' (G),(H)]

解决方案

It can be quite tricky to form such domains. In those cases you can use odoo.osv.expression helpers, which take a list of domains (not a list of leafs). Example:

>>> from odoo.osv.expression import AND, OR                                                                                                                                                                 

>>> a,b,c,d,e,f,g,h = ([("field_" + x, "=", "value_" + x)] for x in "ABCDEFGH")                                                                                                                             

>>> OR([a, b, OR([c, AND([d, e]), AND([f, g, h])])])                                                                                                                                                        
['|', '|', ('field_A', '=', 'value_A'), ('field_B', '=', 'value_B'), '|', '|', ('field_C', '=', 'value_C'), '&', ('field_D', '=', 'value_D'), ('field_E', '=', 'value_E'), '&', '&', ('field_F', '=', 'value_F'), ('field_G', '=', 'value_G'), ('field_H', '=', 'value_H')]

Note: I had to convert your variables into valid domains or the methods wouldn't work.
