Hello, I noticed that when setting passive_deletes="all" on a relationship and try to delete the parent object sqlalchemy still tries to query the child object. For the way my models are set up I can't have the child object be queried. I'm using a hybrid of horizontal and vertical sharding in this relationship and sometimes the corresponding table does not exist so it cannot be queried.
I have a patch that seems to fix the problem but I don't understand sqlalchemy enough to know if this is the proper fix or if it should be done somewhere else. http://pastebin.com/wd2Dsdwu This particular problem does not occur with passive_deletes=True but other problems occur because I don't want existing objects to have any fields nullified either if they are loaded in sqlalchemy. I narrowed down the reason why this occurs to orm/attributes on line 383 but that doesn't seem to be the appropriate place for the fix. Thanks for any input. -Will -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group. To post to this group, send email to sqlalch...@googlegroups.com.
