Rails 3: Mongoid::Errors::NoSessionsConfig - ruby-on-rails

Question

I'm unable to use mongoid in production mode in my rails application. I'm using Rails 3.2.14 and mongoid 3.0.23
Mongoid::Errors::NoSessionsConfig (
Problem:
No sessions configuration provided.
Summary:
Mongoid's configuration requires that you provide details about each session that can be connected to, and requires in the sessions config at least 1 default session to exist.
Resolution:
Double check your mongoid.yml to make sure that you have a top-level sessions key with at least 1 default session configuration for it. You can regenerate a new mongoid.yml for assistance via `rails g mongoid:config`.
Example:
  development:
    sessions:
      default:
        database: mongoid_dev
        hosts:
          - localhost:27017
):
Everything works fine in developement mode. Here's the mongoid.yml.
production:
sessions:
default:
database: myapp_production
hosts:
- localhost:27027
username: username
password: password
options:
raise_not_found_error: false
use_activesupport_time_zone: true
identity_map_enabled: true
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: myapp_development
# Provides the hosts the default session can connect to. Must be an array
# of host:port pairs. (required)
hosts:
- localhost:27017
test:
sessions:
default:
database: chanderi_test
hosts:
- localhost:27017
options:
consistency: :strong
# In the test environment we lower the retries and retry interval to
# low amounts for fast failures.
max_retries: 1
retry_interval: 0
How should I set up the database?

Answer 1

In your mongoid.yml in development section you have Mongoid specific options as empty, if you want to put some options then paste it after options: otherwise remove this line as due to that it is not able to detect test environment and giving error. Your mongoid.yml should be like this
production:
sessions:
default:
database: myapp_production
hosts:
- localhost:27027
username: username
password: password
options:
raise_not_found_error: false
use_activesupport_time_zone: true
identity_map_enabled: true
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: myapp_development
# Provides the hosts the default session can connect to. Must be an array
# of host:port pairs. (required)
hosts:
- localhost:27017
test:
sessions:
default:
database: chanderi_test
hosts:
- localhost:27017
options:
consistency: :strong
# In the test environment we lower the retries and retry interval to
# low amounts for fast failures.
max_retries: 1
retry_interval: 0
