Odoo：如何在 product.category 中搜索 parent_id 及其所有子代

如何解决Odoo：如何在 product.category 中搜索 parent_id 及其所有子代

我想，当用户选择（通过 Many2one 字段）一个类别时，我需要为 parent_id 找到其相关的 Brands 以在另一个 Many2one 字段上添加域过滤器以具有相关的子条目这些品牌。由于我是初学者，我无法做到这一点。

假设 Many2one 字段 category_id 在这里，用户将从前三个条目中选择一个类别，现在我们知道用户想要添加一个与电子产品相关的项目，然后系统应该在电子相关品牌上填充 Many2one 字段 brand_id （所有/电子产品/品牌除外）从以下最后 2 个条目中选择所有/电子产品。

All / Electronics / Personal Computers
All / Electronics / Personal Computers / Laptop
All / Electronics / Personal Computers / Desktop
... 
...
All / Electronics / Brands
All / Electronics / Brands / HP
All / Electronics / Brands / IBM

此模型中有更多品牌（表格数据），例如：

All / Foods / Brands
All / Foods / Brands / Hershey
All / Foods / Brands / Heinz
All / Foods / Brands / Oreo
...
All / Services / Brands
All / Services / Brands / IBM Garages
All / Services / Brands / Telos MNS
All / Services / Brands / Relia Quest
...

我的自定义模型类：

class OrderItems(models.Model):
    _name = 'tests.orderitems'
    _description = "Tests Order Items"

    store_id = fields.Many2one('tests.stores',string="Store",ondelete='cascade')
    order_id = fields.Many2one('tests.testsorders')
    categry_id = fields.Many2one('product.category',string="Category",domain="[['complete_name','not like','%Brands%']]")
    items_id = fields.Many2one('tests.storeitems',string="Item",domain="[['categs_id','=',categry_id]]")
    brand_id = fields.Many2one('product.category',string="Brand",'like','%Brands%']]")
    unit_id = fields.Many2one('tests.units',string="Unit")
    quantity = fields.Integer(string="Quantity",required=True,default=1)
    rates = fields.Float(string="Rate",default=0)
    size = fields.Char(string="Size")

请帮忙，我该怎么做。

解决方法

将您的brand_id域更改为：

char *problematicFunction(char *arg) 
{
    char *buff = malloc(PATH_MAX);
    static char temp[PATH_MAX];

    // Doing stuff with buff...

    if (strlcpy(temp,buff,sizeof(temp)) >= sizeof(temp))
    {
        // Handle error...
    }

    free(buff);
    return(temp);
}

@SDBot，此特定模型的 xml 代码在这里...

            <notebook>
                <page string="Order Items">
                    <field name="order_ids">
                        <tree editable="bottom" string="Order Items">
                            <field name="store_id"/>
                            <field name="categry_id"/>
                            <field name="items_id"/>
                            <field name="categ_name"/>
                            <field name="brand_id"/>
                            <field name="unit_id"/>
                            <field name="quantity"/>
                        </tree>
                    </field>
                </page>
            </notebook>

在brand_id中添加字段categ_name和域的模型

class OrderItems(models.Model):
    _name = 'tests.orderitems'
    _description = "Tests Order Items"

    store_id = fields.Many2one('tests.stores',string="Store",ondelete='cascade')
    order_id = fields.Many2one('tests.testsorders')
    categry_id = fields.Many2one('product.category',string="Category",domain="[['complete_name','not like','%Brands%']]")
    items_id = fields.Many2one('tests.storeitems',string="Item",domain="[['categs_id','=',categry_id]]")
    categ_name = fields.Char('Category Name',related='categry_id.complete_name')
    brand_id = fields.Many2one('product.category',string="Brand",domain="[('complete_name','like',categ_name),('complete_name','!=',categ_name)]")
    unit_id = fields.Many2one('tests.units',string="Unit")
    quantity = fields.Integer(string="Quantity",required=True,default=1)
    rates = fields.Float(string="Rate",default=0)
    size = fields.Char(string="Size")
