ruby-on-rails mongodb heroku mlab mongoid4

Error when seeding mongoDB thru heroku

Hello I have an app that I built on heroku and I can’t seem to get the mlab DB to work. It seems to connect but when I run heroku run rake db:setup I get an error and can’t see what it is.

I upgraded to a paid account but that hasn’t fixed the problem. Please help me figure this out. Here is my mongoid.yml file

# Tell Mongoid which environment this configuration is for. 
production:   
  sessions:
  default:
  uri: <%= ENV['MONGOLAB_URI'] %>

development:   
  sessions:
  default:
  database: myapp_development
  hosts:
    - localhost:27017
  options:   options:

test:   
  sessions:
  default:
    database: myapp_test
    hosts:
      - localhost:27017
      options:
      read: primary
      max_retries: 1
      retry_interval: 0

My error is extremely long and I can’t seem to see the top lines but here is the top of what I can see.

/app/vendor/bundle/ruby/2.2.0/gems/moped-2.0.7/lib/moped/operation/read.rb:56:in `block (2 levels) in execute' /app/vendor/bundle/ruby/2.2.0/gems/moped-2.0.7/lib/moped/node.rb:118:in `block in connection' /app/vendor/bundle/ruby/2.2.0/gems/connection_pool-2.2.0/lib/connection_pool.rb:64:in `block (2 levels) in with' /app/vendor/bundle/ruby/2.2.0/gems/connection_pool-2.2.0/lib/connection_pool.rb:63:in `handle_interrupt' /app/vendor/bundle/ruby/2.2.0/gems/connection_pool-2.2.0/lib/connection_pool.rb:63:in `block in with' /app/vendor/bundle/ruby/2.2.0/gems/connection_pool-2.2.0/lib/connection_pool.rb:60:in `handle_interrupt' /app/vendor/bundle/ruby/2.2.0/gems/connection_pool-2.2.0/lib/connection_pool.rb:60:in `with' /app/vendor/bundle/ruby/2.2.0/gems/moped-2.0.7/lib/moped/node.rb:116:in `connection' /app/vendor/bundle/ruby/2.2.0/gems/moped-2.0.7/lib/moped/operation/read.rb:52:in `block in execute' /app/vendor/bundle/ruby/2.2.0/gems/moped-2.0.7/lib/moped/node.rb:608:in `[]' /app/vendor/bundle/ruby/2.2.0/gems/moped-2.0.7/lib/moped/node.rb:608:in `block (3 levels) in flush’

Thanks for any help.

BTW I am running mongoid 4.0.2 and rails 2.2.1

--UPDATE--

I ran heroku run rake --trace db:setup

I got this response...

It seems to be creating the db but not able to seed it. However when I go and look at the db nothing is their which makes me think maybe it starts building the db and when the seed fails it destroys what it did.

Solution

The problem turned out to be that the DB I was using in development was an older version of MongoDB. I upgraded to MongoDB 5 and everything worked after a little revision.
