夏娃例外：重复 config_prefix "MONGO"`

Question

from views import app
    mongo = PyMongo(app)
    print mongo.db.activity.count()

因为我正在尝试使用 Pymongo count()

它会加注

File "Z:\Activities\modules.py", line 9, in set_id
    mongo = PyMongo(app)
  File "D:\Python27\lib\site-packages\flask_pymongo\__init__.py", line 98, in __init__
    self.init_app(app, config_prefix)
  File "D:\Python27\lib\site-packages\flask_pymongo\__init__.py", line 122, in init_app
    raise Exception('duplicate config_prefix "%s"' % config_prefix)
Exception: duplicate config_prefix "MONGO"

但其实我用的是default。我该怎么办？

PyMongo 已经为您初始化，可以在 app.data.driver 使用。

尝试以下方法：

mongo = app.data.driver
print mongo.db.activity.count()
