Many thanks for reply however this doesn't seem to be a complete fix - code
is failing on the 'in' piece of this filter function and I am not clear
how this relates to the belongs code up above.

GAE_FILTER_OPTIONS = {
'=': lambda q, t, p, v: q.filter(getattr(t,p) == v),
'>': lambda q, t, p, v: q.filter(getattr(t,p) > v),
'<': lambda q, t, p, v: q.filter(getattr(t,p) < v),
'<=': lambda q, t, p, v: q.filter(getattr(t,p) <= v),
'>=': lambda q, t, p, v: q.filter(getattr(t,p) >= v),
'!=': lambda q, t, p, v: q.filter(getattr(t,p) != v),
'in': lambda q, t, p, v: q.filter(getattr(t,p).IN(v)),
}
def filter(self, query, tableobj, prop, op, value):
return self.GAE_FILTER_OPTIONS[op](query, tableobj, prop, value)
