Hi Marzia, heres everything i could think of that might be relevent:
[Edit Item -> ImgItem]:
ImgItem.gql('WHERE style = :style and merchant in :merchants ORDER BY
__key__',style=theStyle,merchants=merchantList)
class Item(BaseModel):
name = db.StringProperty()
cumulative_avg = db.FloatProperty()
cumulative_count = db.IntegerProperty()
def __eq__(self, other):
if isinstance(other, Item):
return self.key() == other.key()
def __hash__(self):
return self.key().__hash__()
class ImgItem(Item):
imgurl = db.StringProperty()
crawl=db.ReferenceProperty(Crawl)
pic=db.ReferenceProperty(Picture,default=None)
style=db.ReferenceProperty(Style)
style_override=db.BooleanProperty()
price=db.FloatProperty()
link=db.LinkProperty()
about = db.TextProperty()
lastUpdate=db.DateTimeProperty(default=None)
merchant = db.ReferenceProperty(Merchant)
class Merchant(BaseModel):
name= db.StringProperty()
Thanks,
Paul.
