Flask_PyMongo：類型錯誤：「數據庫」對象不是可調用

這簡單的代碼從一個更大的片降低生成關於pymongo「發現」錯誤撥打：Flask_PyMongo：類型錯誤：「數據庫」對象不是可調用

from flask import Flask, request, jsonify 
from flask_pymongo import PyMongo 
from os import environ 

CLIENT_PATH = "/api/v1.0" 

app = Flask(__name__) 
app.config['MONGO_URI'] = environ.get('MONGODB_URI', "mongodb://localhost:27017/test") 
mongo = PyMongo(app) 

@app.route(CLIENT_PATH, methods=['GET']) 
def getClients(): 
     data = [] 
     cursor = mongo.db.client.find({}, {"_id": 0}) 
     for item in cursor: 
      client_detail = {} 
      client_detail['url'] = CLIENT_PATH + "/" + str(item.get('id')) 
      client_detail['clientTitle'] = str(item.get('firstName')) + " " + str(item.get("familyName")) 
      data.append(client_detail) 
     return jsonify({"status": "success", "payload": data}) 

if __name__ == "__main__": 

    app.run(debug=True)

，如果我用蟒運行此2.7，並從「http://localhost:5000/api/v1.0」我收到以下錯誤消息瀏覽器撥打電話：

 File "/Users/markschulz/Projects/client/flask-client/app.py", line 16, in getClients 
    cursor = mongo.db.client.find({}, {"_id": 0}) 
    File "/Users/markschulz/Projects/client/venv/lib/python2.7/site-packages/pymongo/database.py", line 1116, in __call__ 
    self.__name, self.__client.__class__.__name__)) 
    TypeError: 'Database' object is not callable. If you meant to call the 'find' method on a 'MongoClient' object it is failing because no such method exists.

軟件版本使用的是：pymongo == 3.4.0瓶== 0.12燒瓶PyMongo == 0.4.1

這裏發生了什麼？

你想要的東西，如：

mongo.db.collection.find({}, {"_id": 0})

其中「DB」是數據庫的名稱和「收藏」是您的集合的名稱。
