Subject: Make it possible to pass instancemaker through backend lists
X-Git-Url: http://git.postgresql.org/gitweb/static/gitweb.js?a=commitdiff_plain;h=d82c5e657aec6fb514a2124d05817ebe9ad55c20;p=pgeu-website.git

Make it possible to pass instancemaker through backend lists

This makes it possible to create objects that do not have a field for
conference. It was pure luck that this worked for ConferenceSeries(),
since it actually accepts a conference value (because of the link), but
it shouldn't have worked. So convert ConferenceSeries to use a dedicated
instancemaker as well.
