I'm trying to do a groupby that gets the last entry for each item checked out by a user from db.checkout (i.e. they've checked it out multiple times, but I just want the last entry). I then want to join on db.item.
db.checkout: user_id item_id (reference item) db.item: item_name WITHOUT the join works perfectly, giving me the last entry for each item checked out by this user: db(db.checkout.user_id == 1).select(groupby=~db.checkout.item_id) But WITH the join, it groups by the FIRST checkout entry for each item_id for this user (although it *displays* those groups in reverse item_id order): db((db.checkout.user_id == 1) & (db.item.id == db.checkout.item_id)).select(groupby=~db.checkout.item_id) What am I missing? -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups "web2py-users" group.
