我正在尝试使用
当然，我运行
Peewee在Flask中对查询结果进行分页。我试图使用playhouse.flask_utils中的object_list函数。
你可以看到object_list的示例似乎非常简单，下面的代码是我正在尝试使其工作的代码：
from flask import Flask
from playhouse.flask_utils import object_list
from peewee import *
from database import *
@app.route("/items/")
def items():
all_items = Quote.select()
return object_list("items.html", all_items)
模板items.html包含以下内容：
<p>Hello world</p>
{% for item in all_items %}
<p>{{ item.text }}</p>
{% endfor %}
{% if page > 1 %}
<a class="previous" href="./?page={{ page - 1 }}">Previous</a>
{% endif %}
{% if pagination.get_pages() > page %}
<a class="next" href="./?page={{ page + 1 }}">Next</a>
{% endif %}
当然，我运行
python app.py，但是收到一个500内部服务器错误。我想对我的查询结果进行分页，你有什么想法如何实现这一点？或者你能看出我在这里做错了什么吗？提前感谢您。
编辑#1，在终端中出现以下错误：
