My app requires an often-repeating procedure where I need to take two
separate values, and choose one of them.
For example:
class Item():
day
player = [red, black]
value
I need to select which value is larger, and then apply a point to
either Reds or Blacks. Which approach is more efficient
Option one: perform two queries to get red and black separately, then
compare them:
red = models.Item.all().filter('day =', day).filter('player =',
red).get()
black = models.Item.all().filter('day =', day).filter('player =',
black).get()
if red.value>black.value:
Reds += 1
else
Blacks += 1
Option two: perform one query to get both values, sort them, then
compare them:
items = models.Item.all().filter('day =', day).fetch(2)
for item in items:
if item.player == 'red':
red = item
else:
black = item
if red.value>black.value:
Reds += 1
else
Blacks += 1
Basically, since I need to repeat this kind of an action very often,
it's worth knowing which is the better approach. Thanks!
