我有一个自定义模块，其中包含三个不同的金额字段：

  • Total a pagar是一个float字段
  • Total pendiente并Total pagado根据函数计算

这就是我的树视图的样子：

当使用按过滤器分组时，我想显示函数字段的总和，但只显示第一个：

我尝试sum在 XML 记录中使用参数，但这不起作用。

这是我的模块：

class res_partner_current_account(osv.osv):
    def _amount_pending_wrapper(self, cr, uid, ids, field_name, arg, context=None):
        """
        Wrapper because of direct method passing as parameter for function fields
        """
        return self._amount_pending(cr, uid, ids, field_name, arg, context=context)

    def _amount_pending(self, cr, uid, ids, field_name, arg, context=None):
        cur_obj = self.pool.get('res.currency')
        res = {}
        for current_account in self.browse(cr, uid, ids, context=context):
            res[current_account.id] = {
                'amount_pending': 0.0,
                'amount_payed': 0.0,
            }
            cur = current_account.currency_id
            payed = 0.0

找到了解决方案。关键是覆盖read_group类的方法：

class your_class(osv.osv):
    # ...        

    def read_group(self, cr, uid, domain, fields, groupby, offset=0, limit=None, context=None, orderby=False, lazy=True):
        res = super(your_class, self).read_group(cr, uid, domain, fields, groupby, offset, limit=limit, context=context, orderby=orderby, lazy=lazy)
        if 'amount_pending' in fields:
            for line in res:
                if '__domain' in line:
                    lines = self.search(cr, uid, line['__domain'], context=context)
                    pending_value = 0.0
                    for current_account in self.browse(cr, uid, lines, context=context):
                        pending_value += current_account.amount_pending
                    line['amount_pending'] = pending_value
        if 'amount_payed' in fields:
            for line in res:
                if '__domain' in line:
                    lines = self.search(cr, uid, line['__domain'], context=context)
                    payed_value = 0.0
                    for current_account in self.browse(cr, uid, lines, context=context):
                        payed_value += current_account.amount_payed
                    line['amount_payed'] = payed_value
        return res


例如，如果您想删除 group by 中列的总和，您可以执行以下操作：

class your_class(osv.osv):
    # ...     

    def read_group(self, cr, uid, domain, fields, groupby, offset=0, limit=None, context=None, orderby=False, lazy=True):
        if 'column' in fields:
            fields.remove('column')
        return super(your_class, self).read_group(cr, uid, domain, fields, groupby, offset, limit=limit, context=context, orderby=orderby, lazy=lazy):
