odoo在底部显示指定字段合计和汇总时显示合计

1.odoo的tree视图底部显示合计

tree 视图，底部显示指定字段合计数 ，视图中字段定义上在sum，取自sale.view_order_tree 销售订单 tree 视图

<field name="amount_total" sum="Total Tax Included"/>

2. odoo使用group by分组时显示字段合计  方法是重写read_group方法

https://stackoverflow.com/questions/27536186/how-to-sum-other-columns-when-using-group-by-in-a-tree-view

The key is to overwrite the read_group method of the class:

class your_class(osv.osv):

    # ...        

    def read_group(self, cr, uid, domain, fields, groupby, offset=, 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

If you want, for example, remove the sum of a column in the group by, you can do something like this:

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):
