what's your mappers? many2one/one2many relations etc?
I expected that I can create a parent-child link either from parent
to child (by appending to ranker.results) or from child to parent
(as above), but apparently the latter doesn't seem to work. Is this
the case or something else is wrong
seems this is the month of the many2many relations ;-)

i have a association of 3 tables, A,B,C.
one of them (C) may not be present in all assoc_items.
So that column has nullable=True.
The problem is: adding associations to A-objects and saving them
works; but

Hi,
is there are any way to add additional joins to a given select object?
My problem is the following, I need to join the same table multiple
times. How many times I don't know in advance and in addition I need
to apply where clause while adding this join.
Thanks,
Valentin.
the select object supports an append_from() method.
however, if you want to chain the joins themselves together, you
probably want to construct the Join object ahead of time and add it
to the select via append_from() (or create the select by calling the
select() method off the Join itself)

when you say, association of 3 tables, A,B, C, do you mean, there

btw whats the reasoning/rational behind the above default behaviour?
i think it is often unexpected behavior, particularly for a query
that returns rows between say table A and table B, where some of the
rows contain nulls for the B
