Question

尝试时，我的代码基本上运行良好。但是，当我尝试访问发布到sqlite3数据库的数据时，我无法在sqlite3中找到最后更新的文本。相反，我得到了以前更新的文本，而不是当前的文本。有没有一种方法可以在发布文本后刷新sqlite3 db，以便我可以访问最近的文本。我想将最近的文本用于某些NLP函数，以便回复给用户。使用sqlite update对我不起作用，因为响应是相同的。这是html代码：

            return false;
        });
    </script>

</body>
</html>

控制器代码：

def viewer():
form = SQLFORM(Post, formstyle='table3cols').process()
    if request.vars:
        r = [request.vars.name]
        codes.append(r[0])
        db.post.insert(name=codes[0])
    row = db(db.post.author== auth.user.id).select(db.post.id, db.post.name, orderby=~db.post.id, limitby=(0,1)).first()
    code = row.name if row else None
    return dict(code=code)

单击按钮，sqlite3刷新数据
