Rails + Mongodb 應用，部署的時候為專案資料庫添加了一個用戶，給了readWrite 權限，然後在rails中配置好之後報錯，說是沒有權限獲取數據，但是在mongo的控制台用該用戶登錄是可以查詢資料的。

mongoid.yml

ymlproduction:
  sessions:
    default:
      hosts:
        - localhost:27017
      database: db
      username: user
      password: password
  options:
    include_root_in_json: true
    include_type_for_serialization: true
    scope_overwrite_exception: true
    raise_not_found_error: false
    use_activesupport_time_zone: false
    use_utc: true

mongo db db.getUsers()

[
    {
        "_id" : "db.dbuser",
        "user" : "dbuser",
        "db" : "db",
        "roles" : [
            {
                "role" : "readWrite",
                "db" : "db"
            }
        ]
    }
]

希望有做過這方面嘗試的給予幫助 謝謝啦！
