hi back to that old question about relation vs query, i have some relation, say m2m via table with some additional fields like timestamps (which are setup automaticaly). so plain relation via secondary join is ok, no really need for explicit assoc_object.
by default, the relation will give me all items, regardless of timing. now, i want to filter by times. it will be done by some function, which will have the timing context and ... what? the easiest answer is python-filtering: [x for x in the_relation if x.fits.filter ] but that would be very expensive. i dont want that relation loaded in full, it's meaningless. so, is it possible easy to obtain the query which the relation will issue, so i additionaly put .filter() on it and issue it myself? no changes to original relation. ciao svil --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
