如何按時間過濾對象

Question

因此可以說我有一個簡單的類最後，我想過濾創建的字段過去2天的結果，我該怎麼做？當我填充最後一課時，它有一個utc創建時間，但我需要那個時間的差異，目前這是我想要做的下面的行，但我不確定如何在所有查詢中獲得差異項目？

class Final(db.Model): 
    name = db.StringProperty() 
    created = db.DateTimeProperty() 

now = datetime.datetime.now() 
##d = now - created 
##if d.days > 2: 
    ## I could loop along something like this but that would be too slow 


results = Final.all() 
results.filter('created =',##what do i do here?) ##would created >, and then now - 2days work? 

Answer 1

我會嘗試：

results.filter('created > ', now - datetime.timedelta(days=2))
