Hi Marzia, Yes Alexander is correct.
I have read the issue and have exact the same problem. In my index.yaml file there is also the following entry as the first index, placed by devappserver.py. ======================= - kind: FooA ancestor: yes ======================= This is because in some cases I want all the FooA objects that have a certain parent. But sometimes I just need a selection of them, and what I heard from a Google IO talk was "If you can: let the Datastore work for you" that is why I added the filter() call. But to work around the bug I have done the work myself and implemented the filter with python if-statement. At the moment the parent does not have a lot of FooA childs but that might not be the case in the future ( and then I get hit by the CPU quota ;-) djidjadji 2008/9/22 Marzia Niccolai <[EMAIL PROTECTED]>: > Hi, > > From the description, it seems as though Alexander is correct, and you are > experiencing the below issue. > > However, if you would like to reply directly to me with the App Id, I can > look in to it and verify if it is this or something else may be happening. > > Thanks, > Marzia > > On Sun, Sep 21, 2008 at 5:33 PM, Alexander Kojevnikov > <[EMAIL PROTECTED]> wrote: >> >> Star this issue: >> http://code.google.com/p/googleappengine/issues/detail?id=423 >> >> On Sep 22, 1:50 am, djidjadji <[EMAIL PROTECTED]> wrote: >> > I have a BarB object that is the parent of a couple of FooA objects. >> > I want to find all the FooA objects that have a certain parent and >> > that have an "myID < 0" >> > >> > barB = BarB.get_by_key_name(keyname) >> > result = FooA.all().ancestor(barB).filter('myID <', 0) >> > >> > When I test it on the devappserver v1.1.3 it works correct, and an >> > entry in index.yaml is made >> > >> > ======================= >> > - kind: FooA >> > ancestor: yes >> > properties: >> > - name: myID >> > ======================= >> > >> > When I upload the new code and try it out I get the following error: >> > >> > ======================= >> > NeedIndexError: no matching index found. >> > This query needs this index: >> > - kind: FooA >> > ancestor: yes >> > properties: >> > - name: myID >> > ======================= >> > >> > When I look in the Dashboard this index is "Serving".
