Mongoid3 / Moped: database = admin command = {: ismaster => 1}

Question

I upgraded the Rails application to 3.2.8 and Mongoid 3 / Moped. Everything works fine in development, on my development machine, while it’s ready for production, and rails c works fine in my production installation. However, the application does not start (deploys on the passenger) and seems to just shut down without making any errors. I set log_level for debugging in production, and this is what I see:

 Creating scope :near. Overwriting existing method City.near.

How to fix it? (For the record, the database I'm trying to use is not called admin.)

Answer 1

Well, it looks like Passenger actually worked on an old ruby ​​1.9.2 installation. Passenger was updated to ruby ​​1.9.3, nginx was recompiled, and then it worked fine again.
