瓶子顯示舊模板？

我做了一個模板的初稿，名爲batch.tpl。我已更新它，但是，舊模板仍顯示。我關閉了控制器腳本並多次重新啓用它。我從模板中刪除一切，除了以下：瓶子顯示舊模板？

cat views/batch.tpl

<HTML> 
<HEAD> 
     <TITLE> Batch Manager </TITLE> 
</HEAD> 

<BODY> 
    THIS ISN'T DISPLAYING IN BROWSER 
</BODY> 
</HTML>

然而，這將不顯示，就在舊模板。

這裏是我的控制器：

cat brew_bottle.py

from bottle import route, run, template, debug, post, request 
import MySQLdb 
import pymongo 
from datetime import datetime, timedelta 
import datetime 


@route('/batch') 
def batch(): 
    con = MySQLdb.connect('localhost', 'root', 'pi', 'brew') 
    cursor = con.cursor() 
    batch_sql = "SELECT name, material, start_date, active, end_begin_date, end_end_date, min_temp, max_temp FROM batch WHERE active='Y'" 
    cursor.execute(batch_sql) 
    batches = cursor.fetchall() 
    return template('batch', batches=batches) 
#... 
debug(True) 
run(host='0.0.0.0', port='8080', reloader=True)

然而，當我去http://<hostname>:8080/batch，我看到，我已經寫了舊模板：
