#load_database_yamlObject

Load the database YAML without evaluating ERB. This allows us to create the rake tasks for multiple databases without filling in the configuration values or loading the environment. Do not use this method.

This uses a DummyERB custom compiler so YAML can ignore the ERB tags and load the database.yml for the rake tasks.

#session_store(new_session_store = nil, **options) ⇒ Object

Specifies what class to use to store the session. Possible values are :cache_store, :cookie_store, :mem_cache_store, a custom store, or :disabled. :disabled tells Rails not to deal with sessions.

Additional options will be set as session_options:

config.session_store :cookie_store, key: "_your_app_session"
config.session_options # => {key: "_your_app_session"}

If a custom store is specified as a symbol, it will be resolved to the ActionDispatch::Session namespace:

# use ActionDispatch::Session::MyCustomStore as the session store
config.session_store :my_custom_store
