Mongodb: db_name must be a string or symbol

Question

In my Rails 3.0.10 app, with Mongoid 2.2.2, I'm getting this error in production (works fine in development):

.../gems/mongo-1.3.1/lib/mongo/util/support.rb:50:in `validate_db_name': db_name must be a string or symbol (TypeError)

I've added this to my environment.rb:

require 'yaml'
YAML::ENGINE.yamler = 'syck'

Also, I've removed the defaults << lines from my mongoid.yml file and replaced them with the defaults.

When I use mongoid-2.2.6, the app starts, but I get the same error when I query the db.

What am I overlooking?

Solved

Needed to specify 'localhost' for the host rather than <%= ENV['MONGOID_HOST'] %>, and also specified the database: name.

Are you sure that correct mongoid.yml gets picked up? Seems like that no config (for that env) can be found. — Sergio Tulentsev, Apr 30 '12 at 00:53
