Connecting to two databases Mongoid

Question

I have two databases that I have to use in my application. I have the following in my mongoid.yml:

development:
  # Configure available database sessions. (required)
  sessions:
    # Defines the default session. (required)
    default:
      # Defines the name of the default database that Mongoid can connect to.
      # (required).
      database: db_development
      username: myusername
      password: mypassword
      # Provides the hosts the default session can connect to. Must be an array
      # of host:port pairs. (required)
      hosts:
        - myserverip:27017
      databases:
        secondary:
          database: db2_development
          username: myusername
          password: mypassword
          # Provides the hosts the default session can connect to. Must be an array
          # of host:port pairs. (required)
          hosts:
           - myserverip:27018          

In my model file:

class MyModel
   include Mongoid::Document
   store_in database: "secondary"
   field :name, type: String
   field :age, type: Integer
end

I have data in MyModel. When I tried to query, I'm go the following error:

Moped::Errors::QueryFailure (The operation: #<Moped::Protocol::Query
  @length=96
  @request_id=5
  @response_to=0
  @op_code=2004
  @flags=[:slave_ok]
  @full_collection_name="secondary.mymodel"
  @skip=0
  @limit=0
  @selector={"name"=>"Tom"}
  @fields=nil>
  failed with error 10057: "unauthorized db:secondary ns:secondary.mymodel lock type:0 client:10.100.55.40"

I tried searching online but could not get any solution. Any help would be appreciated. Thanks in advance.

hmm well can you do this seem like you messed your yaml file

development:
  sessions:
    default:
      database: db_development
      username: my_username
      password: my_password
      hosts:
        - myserverip:27017
      options:
        consistency: :eventual
    writeable:
      database: db2_development
      username: myusername2
      password  mypassword2
      hosts:
        -  myserverip2:27018
      options:
        consistency: strong

In your model just write this

store_in session: "writeable"

class MyModel
   include Mongoid::Document
   store_in session: "writeable"
   field :name, type: String
   field :age, type: Integer
end

FYI Never tested with password options but i guess it would work

Hope this help
