Error messages without a model

Is there an easy way to create error messages and display them in the
view without using a model from ActiveRecord. I just quickly added a
temporary new field to a form that I have no desire to store in the db
and will probably remove it shortly. I used text_field_tag on the view
which doesn't require a model but if it's not provided by the user I
still want to return the error message to the view. I was just hoping
for a simple way to return error messages to the view without having
to add them to a model.

It sounds like the flash method, probably along with some logic to redirect_to :back in the case of an error, should give you what you're looking for.
