Hey all,
I decided to play with app engine and got stuck on this problem.
I have two entities List and ListItem. What I need to do is to
associate many ListItems with a List however i cannot simply
use db.ReferenceProperty in ListItem class because each ListItem can
be part of multiple Lists. I figured that we can use
db.ListProperty(db.key) in List class to keep multiple list items but
is this
efficient if each list would have about 100-200 items? However last
method,
cannot be used in my case becuase I need
priority value for each ListItem and priority of ListItem might differ
between different Lists for same ListItem so approach with
ListProperty(db.key) doesnt work. I ended with this:
class List(db.Model):
name = db.StringProperty()
class ListToListItem(db.Model):
list = db.ReferenceProperty(List)
item = db.ReferenceProperty(ListItem)
priority = db.Int...
class ListItem(db.Model):
name = db.StringProperty()
Am I doing this right or there is a better/efficient way?
Thank you in advance,
Dmitriy
