服务端内容：

            upload_file = path.join(upload_path,secure_filename(file.filename))
            file.save(upload_file)
            flash('upload file %s complete!' %file.filename)

        else:
            flash('nothin file select or file type error!')

    serverlists = wwGame.query.all()
    patchform = PatchCommandForm()
    if patchform.validate_on_submit():
        session['cmdpatch'] = patchform.patchcommand.data
        session['serverID'] = request.form.getlist('dbcheckbox')


        #判断是否选服
        if session.get('serverID') == []:
            flash(u'未选游戏服,请勾选游戏服!')
            return redirect(url_for('ww.Patchww'))

        for db in session.get('serverID'):
            dbsql = wwGame.query.filter_by(serverId=db).first()
            dbhost = dbsql.serverHost
            dbname = dbsql.serverName
            session['dbname'] = dbname
            session['dbhost'] =dbhost
            print session.get('dbhost')
        print session.get('cmdpatch')
        return redirect(url_for('ww.Patchww'))
    return render_template('ww/patchww.html',
                           serverlists=serverlists,
                           patchform=patchform,
                           )

当使用第二个form时，也就是上传文件的时候：

出现了：'patchform' is undefined
但是 patchform 是第一个form的定义内容。这为咋提交的时候会触发第一个from 的？

===================

使用ajax解决了，新问题出现了

form1,form2其实对应了两个后端的views，当form2的views上传完文件后，form1的views里要怎样获得刚刚上传的文件的文件名？
即：
@ww.route('/Patchww',methods=['GET','POST']) 要怎样取到@ww.route('/upload',methods=['POST','GET'])这里面的file.filename值？

Ajax提交到不同链接不就好了
