Yeah, I was wrong Vijay. For some odd reason I thought the ValidationError
would catch it BEFORE submitted. . .
I re-read the docs and saw I was wrong. .
In other words, I I try to submit the form with the input field empty, I
get a small pop up error saying "Please Enter An Email".
Or, if I use an invalid email format, I get the same popup error saying
"Please Enter An Email Address."
Is there a way to do this with this (with django)?
