【问题描述】:
我正在尝试按照以下教程进行操作,但是当我运行 manage.py 时遇到了一些问题。任何帮助都可能是很大的帮助。
http://docs.mongodb.org/ecosystem/tutorial/write-a-tumblelog-application-with-flask-mongoengine/#id1
manage.py 运行输出:
(Tumbler)afiz Tumbler $ python manage.py
Traceback (most recent call last):

""".strip() % name)
mongoengine.errors.NotRegistered: `Comment` has not been registered in the document registry.
Importing the document class automatically registers it, has it
been imported?
manage.py 文件:
#set the path
import os, sys
sys.path.append(os.path.abspath(os.path.join(os.path.dirname(__file__), '..')))
from flask.ext.script import Manager, Server
from tumblelog import app
manager = Manager(app)
# Turn on debugger by default and reloader
manager.add_command("runserver", Server(
use_debugger = True,
use_reloader = True,
host = '0.0.0.0')
)
if __name__ == "__main__":
manager.run()

你的模型是什么样的?

PIP 冻结输出:

@stillfool 的回答对我有用。你呢?你可能应该接受它,用一些点勾结一个朋友。
