ConnectionException connecting a Eve REST API to a MongoDB instance

Question

I just installed the 'eve demo' I can't get it to start working.

The error is:

eve.io.base.ConnectionException: Error initializing the driver. Make sure the database serveris running. Driver exception: OperationFailure(u"command SON([('authenticate', 1), ('user', u'user'), ('nonce', u'cec66353cb35b6f5'), ('key', u'14817e596653376514b76248055e1d4f')]) failed: auth fails",)

I have mongoDB running, and I have installed Eve and Python2.7.

I create the run.py and the settings.py required.

What is not working ? am I missing something ?

Answer 1

It looks like the MongoDB user/pw combo you configured in your settings.py has not been set at the db level. From the mongo shell type use <dbname>, then db.system.users.find() to get a list of authorized users for <dbname>. It is probably empty; add the user as needed (see the MongoDB docs).

Answer 2

1. get your mongodb's dbname,username and password from setting.py,eg:

   MONGO_USERNAME = 'username'
   
   MONGO_PASSWORD = 'password'
   
   MONGO_DBNAME = 'apitest'
   

2. login in mongod server with mongo,and make sure your username in dbname's system.user collection.you can query authenticated users in that database with the following operation:

   use apitest
   
   db.system.users.find()
   

3. if username doesn't exist in system.users,then you can use db.addUser command to add a user to system.users collection.eg:

   use apitest
   
   db.addUser{'username','password'}
