Comment:
vini.reis: The benefit of using server-side validation in general is
twofold:
* Code duplication is reduced. Something doesn't have to be written in
both Python and Javascript in order to work.
* Some inputs may not be validatable client-side (e.g. validating that a
Latitude/Longitude coordinate was over land and not over water, which
would require a GIS database).
That being said, there are certainly issues with server-side validation:
* A lot more traffic for the `XmlHttpRequest`s that could have been
addressed entirely at the client.
* Multi-input validation either wouldn't get done, or would have to be
triggered on all changes.
I am not familiar with Django's admin interface, but something like this
would be quite useful in any Django-powered application, so it could be
worth developing generically.
