0.6.0 and 0.6.0.rc3 not work for mongoid, undefined method `const_get' for nil:NilClass (NoMethodError)

Hmm... I've been using Mongoid with v0.6.x for several months now. I've been using it without a problem with Rails 3.0. Did you set the strategy to be :truncation?

[stonegao]

yes. I tried DatabaseCleaner[:mongoid].strategy = :truncation, it failed.

Now I am using v0.5.2 with config :
DatabaseCleaner.orm = "mongoid"
DatabaseCleaner.strategy = :truncation

it works.

Any way you could reproduce this in a new project and push it to github? Something different in your setup is causing this bug where my setup and the tests are not catching...

[stonegao]

Hi, I pushed a example project at: git://github.com/stonegao/databasecleaner-debug.git
you can run:

rake spec

to reproduce the bug

Thanks for taking the time for creating this! I was quickly able to spot the problem. The main problem is that DatabaseCleaner was not converting the orm type into symbols. So, you were passing "mongoid" but internally symbols are used for comparison and since #to_sym was never being called there were issues...

This has also brought up a couple more issues where DatabaseCleaner could issue better warnings and provide better documentation. Anyways, I will work on some patches to avoid these issues in the future. For now, take a look at my commit to see what I had to do to make it work correctly:

[stonegao]

cool. thanks for the fix :-)

I just pushed a fix to database_cleaner's master and have created a new ticket based off of another bug I found with this setup. Thanks again!
