Question

I just got bit by my functional tests not using the same settings as my dev_appserver. I currently run my dev_appserver (non-rel) with require_indexes.

How to I force my test bed to use the same setings?

I have tried using SetupIndexes but it did not “require” they be defined in my index.yaml. I did not have the setting correct and as a result i can do any query I want.

i.e.

clz.testbed = Testbed()
clz.testbed.activate()
clz.testbed.init_memcache_stub()
clz.testbed.init_taskqueue_stub()
clz.testbed.init_urlfetch_stub()
clz.testbed.init_datastore_v3_stub(use_sqlite=True, datastore_file=somepath)
SetupIndexes('','')

model.objects().filter(x=1, y=2.....) #will work regardless of index defined.

but when the query executes on the server i get the

NeedIndexError: This query requires a composite index that is not defined. You must update the index.yaml file in your application root.
The following index is the minimum index required:

Answer 1

Try adding { “require_indexes” : True } as a keyword argument to init_datastore_v3_stub()

You can look through (and step through) the SDK code to see how that parameter is eventually passed into the datastore stub.
