Re: Can I POST edit form to detail view, and redirect back if invalid?

You're correct: HTTP does not allow you to, say, send POST data along
in a 30X (redirect) response [1]. You can redisplay the form at your
object's URL, but in order to actually do an HTTP redirect back to the
form URL, you'd have to pass the form data along in the URL query
string or store it on the session or something. The easiest thing to
do in most cases is to POST to the /edit/ URL and redirect to the
detail page (or somewhere else) if valid. This is what the [Create|
Update]View classes do. Could you provide a little more context on
why this is infeasible in your code? Maybe an snippet?
