I have ten entities in my Feed model ( this is an App Engine model)
class Feed(db.Model):
sometext = db.StringProperty()
timestamp = db.DateTimeProperty(auto_now=True)
list_of_keys = ["key1","key2","key3".... "key10"]
so i call my entities using db.key() method:
feeds = db.keys(list_of_keys)
# this loop below prints the feed
for feed in feeds:
print humanizeTimeDiff(feed.timestamp)
# humanizeTimeDiff is a function to change the raw timestamp into a human friendly
# version: eg-> 10 mins ago, 20 seconds ago
but now, how do I sort the feeds according to timestamp? ( I want the newest feeds at the top and the oldest ones at the bottom)
any sort function I can use on the raw timestamp? ( my rough plan is to sort according to the raw timestamp, then humanize the time difference )
PS: I don't plan to use GQL query to query my entities according to timestamp, because I get my input in the form of a list of keys. And using db.key() is a faster method.
hope I supplied enough info. wish to hear your thoughts/solutions.
