odoo使用group by分组时显示字段合计

方法是重写read_group方法

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=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

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):
