odoo 清除所有运行数据

测试odoo，如果需要一个干净的db。经常需要清除掉所有业务数据。做如下操作，较为方便

1：建立一个服务器动作，动作的python代码入下。 然后新建一个菜单，菜单动作关联到 这个动作。需要清空db，点击这个菜单就OK啦。

to_removes = [
        ['procurement.order',],
        ['purchase.order.line',],
        ['purchase.order',],

        ['stock.quant',],
        ['stock.move',],
        ['stock.pack.operation',],
        ['stock.picking',],
        ['stock.inventory.line',],
        ['stock.inventory',],
        ['stock.quant.package',],
        ['stock.quant.move.rel',],
        ['stock.production.lot',],
        ['stock.fixed.putaway.strat',],
        ['mrp.production.workcenter.line',],
        ['mrp.production',],
        ['mrp.production.product.line',],
        ['sale.order.line',],
        ['sale.order',],
        ['pos.order.line',],
        ['pos.order',],

        ['account.voucher.line',],
        ['account.voucher',],
        ['account.invoice',],
        ['account.partial.reconcile',],
        ['account.move',],
]

def remove_data(cr):
        try:
            for line in to_removes :
                obj_name = line[0]
                obj = self.pool.get(obj_name)
                if obj and obj._table_exist:
                    sql = "delete from %s" % obj._table
                    cr.execute( sql)


        except Exception, e:
            raise Warning(e)

        return True

remove_data(cr,)
