Sure. Full details are on
http://code.google.com/appengine/docs/python/datastore/modelclass.html
hit on /confirm/account/(?P<account>.*)$
key_name = 'account:' + account
acc = Account.get_by_key_name(key_name)
if not acc:
template_values = {'account' : account}
template_file = os.path.join(os.path.dirname(__file__),
'templates', 'NoAccount.html')
body = template.render(template_file, template_values)
self.response.out.write(body)
logging.warning( account + " not found" )
return False
This is trivial and user confirmations (and all the stuff that comes
with having good passwords, forgetting passwords, changing emails,
etc.) is probably best done with other tools.
Where it starts to matter a lot on GAE is where it's something like an
URL or email or phone number or part number. These are (or can be)
things that have one entry or no entry. For something like Reddish,
it might be Url.get_by_key_name('url:http://www.web2py.com/article')
to see if the article can be entered.
Url.get_or_insert('url:http://www.web2py.com/article') means "get this
key_name if it exists, otherwise create it" If you have a clear
naming scheme, it makes it easy to use an item that might not have
existed until just now. Example might be tracking Twitter
usernames. We don't know if we saw /jdeibele or /web2py before but
now he's referencing /web2py so we'd get_or_insert('user:web2py') and
add a ReferenceProperty to get_or_insert('user:jdeibele')
