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
