python - RethinkDB 连接属性错误

Question

我正在尝试为 RethinkDB API 制作一个包装器模块，但在导入我的类(称为 rethinkdb.py)时遇到了 AttributeError。我在具有共享文件夹“Github”的虚拟机中工作。

我在 IPython 控制台中这样做:

import library.api.rethinkdb as re

这是错误:

Traceback (most recent call last):

File "", line 1, in import library.api.rethinkdb as re

File "/media/sf_GitHub/library/api/rethinkdb.py", line 51, in conn = Connection().connect_to_database()

File "/media/sf_GitHub/library/api/rethinkdb.py", line 48, in connect_to_database raise e

AttributeError: 'module' object has no attribute 'connect'

这是代码:

import rethinkdb as r  #The downloaded RethinkDB module from http://rethinkdb.com/

class Connection(object):
    def __init__(self, host='127.0.0.1', port=28015, database=None, authentication_key=''):
        self.host = host
        self.port = port
        if database is None:
            self.db = 'test'
        self.auth_key = authentication_key

    def connect_to_database(self):
        try:
            conn = r.connect(self.host, self.port, self.db, self.auth_key)
        except Exception, e:
            raise e
        return conn    

conn = Connection().connect_to_database()

我今天遇到了类似的事情，我注意到作者在后来的版本中改变了 API 的基本行为。

根据我在我的机器上测试过的内容:

v2.3.0

import rethinkdb as r
r.connect()

v2.4.1

import rethinkdb as r
rdb = r.RethinkDB()
rdb.connect()
