odoo action方法

二、动作按钮里面也可以由字段判断：

def action_select_sale_order_line(self,cr,uid,ids,date_begin,date_end,context=None):
    res={}
    record=[]
    seq=1
    selfobj=self.browse(cr,uid,ids,context)
    # date_begin=selfobj.date_begin
    # date_end=selfobj.date_end
    if date_begin and date_end:
        if date_begin<date_end:
            sql="select id,product_id,partner_id,product_qty,date_planned,COALESCE(memo,'') memo from sale_origin_line where date_planned>='%s' and date_planned<='%s'"%(date_begin,date_end)
            cr.execute(sql)
            dict=cr.dictfetchall()
            if dict:
               for line in dict:
                 record.append({'sequence':seq,'partner_id':line['partner_id'],'sale_order_ids':line['id'],'product_id':line['product_id'],'qty':line['product_qty'],'date_planned':line['date_planned'],'lnote':line['memo']})
                 seq+=1

    return {'value':{'lines':record}}

一、一般的按钮动作的写法：
 ####整张外部订单取消,对应取消未发货的内部销售订单
def action_cancel_sale_order(self,cr,uid,ids,context=None):
    assert len(ids)==1
    sale_origin_obj=self.browse(cr,uid,ids,context)
    a=sale_origin_obj.name
    sql="select  id from  stock_picking where order_name='%s'"%(str(a))
    cr.execute(sql)
    dict=cr.fetchall()
    count=len(dict)
    if count >0:
        raise osv.except_osv((u'警告!'),(u'已存在发货单不可取消，请点完结'))
    sale_origin_obj.state='cancel'
    for line in sale_origin_obj.line_id:
         line.state='cancel'
