That's odd, try running a cleanup via gem cleanup mongify, then uninstall and reinstall. Also, it might be an issue if you're using rbenv, you need to run rbenv rehash to re-setup the bins.

[allthatnet]

OK, there may have been some environment issues. I did not set up rbenv explicitely, but some gems required ruby-2.2, so I had rh-ruby22-ruby set up from SCL resposistory.

Here is the full(-er) stack now:

I'm sorry to say, but this is outside of my skill set.

The only thing I can think of is that one of your field names (in the database) is similar to something that ActiveRecord uses (like table_name or connection), this makes the system reference itself.

If you are OK with sharing your database schema, I can try to see if I can see something there.

Good luck, Andrew

It turned out to be an issue with the schema. I confirmed it by gradually translating more and more tables, starting with just one, until I uncovered the one that was causing problems. Then, similarly modified the schema for the "faulty" table until I found a field definition that was causing a problem.

I appreciate you taking the time to track it down, let me know if you find anything.
