RethinkDB 连接 AttributeError [英] RethinkDB connect AttributeError

问题描述

我正在尝试为 RethinkDB API 制作一个包装模块，但在导入我的类(称为 rethinkdb.py)时遇到了 AttributeError.我正在使用共享文件夹Github"的虚拟机工作.

I'm trying to make a wrapper module for the RethinkDB API and I've come across an AttributeError when importing my class(called rethinkdb.py). I'm working in a virtual machine having a shared folder 'Github'.

我在 IPython 控制台中执行此操作:

I do this in IPython console:

import library.api.rethinkdb as re

这是错误:

回溯(最近一次调用最后一次):

Traceback (most recent call last):

文件"，第 1 行，在导入 library.api.rethinkdb as re

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

文件/media/sf_GitHub/library/api/rethinkdb.py"，第 51 行，在conn = Connection().connect_to_database()

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

文件/media/sf_GitHub/library/api/rethinkdb.py"，第 48 行，在connect_to_database提高e

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

AttributeError: 'module' 对象没有属性 'connect'

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()

推荐答案

我今天遇到了类似的问题，我注意到作者在以后的版本中改变了 API 的基本行为.

I ran into something similar today and I noticed the authors have changed basic behavior of the API in the later versions.

根据我在我的机器上测试过的:

From what I have tested on my machine:

v2.3.0

import rethinkdb as r
r.connect()

v2.4.1

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