if youre adding ClauseElements to select_by, all the "automatic joining" logic does not take effect for those.
By ClauseElement, i mean when you say: select_by(someclass.c.somecol == 'somevalue') the "==" operation produces a new object called a ClauseElement, and is passed to the select_by function as a positional argument (i.e. using *args). it is *not* the same as saying: select_by(somecol='somevalue') which is a keyword argument (i.e. using **kwargs). in that version, 'somecol' is interpreted as a mapped property, not a column, and can be reconciled against its role in the mapper relationship (i.e. it figures out the joins). if you want to use ClauseElements and also have joining, look into using the select() method with a combination of join_by/join_via. For this kind of thing also, I find the SelectResults extension makes it easier. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
