Ruby on Rails

THanks for your response. The validation methods are not called on a
create, allowing the save method to be called, unprotected. I dont
want the save to be called let alone fail.

The validation method should stop the save method from being run and
redirect the user to the new action/view with errors displayed, right?

The validation methods in the model are called on an update and errors
reported back to the view. And I dont know why I am getting expected
validating behaviour with an update but not with a create.

I can post the error logs in the morning, but, on a create, they
report a rollback, a 500 error, because the failed save call triggers
the unexpected view to be routed.
