Odoo 覆盖继承的方法

Question

您好，我想覆盖 product_template 中的 unlink() 方法，该方法已被模块 point_of_sale 继承。现在，每当我继承此方法时，我都需要调用超级函数（以便调用 Odoo ORM 中的原始取消链接方法）。但是如果我这样做，首先调用 point_of_sale 中的取消链接（继承链）。任何想法也中断这个继承链并放置我的自定义方法而不是 point_of_sale > unlink 方法？

我需要这个来忽略这段代码中的警告，然后继续。如果其他解决方案也可以工作。

Point_of_sale > unlink() 方法：

def unlink(self, cr, uid, ids, context=None):
    product_ctx = dict(context or {}, active_test=False)
    if self.search_count(cr, uid, [('id', 'in', ids), ('available_in_pos', '=', True)], context=product_ctx):
        if self.pool['pos.session'].search_count(cr, uid, [('state', '!=', 'closed')], context=context):
            raise osv.except_osv(_('Error!'),
                _('You cannot delete a product saleable in point of sale while a session is still opened.'))
    return super(product_template, self).unlink(cr, uid, ids, context=context)

Answer 1

可以通过改变super中的调用来传链

# i think this will import the class
# if not then try to find to correct import statement because this
# the only way to do it and this technique worked for someone else
from openerp.addons.point_of_sale.poin_of_sale import product_template as product_template_pos

# in your method pass that class to super not your class
return super(product_template_pos, self).unlink(cr, uid, ids, context=context)

NOTE that you have to add point_of_sale in the depends of the module
