You might want to try something like this:
else
flash[:warning] = @user.errors.full_messages.join("<br />")
render :action => "new"
end
and put <%= flash[:warning] %> somewhere in your view.
There's also a way to get your model validations to show in the form,
but I don't have an example of how to do such a thing. Of course,
@user.errors will also be sent to your view if you don't specify the
flash like I did above, but I like this way more because you will be
able to re-use this solution or even include the flash somewhere in
your layout.
Hope this helps!
