I suspect this is because it has to hit the database...

I added the following to test_helper.rb. I see messages from logger.debug statements directly inside tests but no messages from logger st...
I got started by following this awesome tutorial, but wanted to do the validation on on keyup and place my errors somewhere else.

But if I ask specifically if a field with remote validation is valid, it says no, actually, its not...

I'm trying to understand what exactly the above (in my question's Title) means?
