Question

Can anyone share your approach for doing a ‘or’ query in app-engine?

Let say I have

class A_db_model(db.Model):
 valueA = db.ListProperty(basestring)

in valueA I have

aaa
aaa, bbb
bbb
ccc

I would like to return result of if the valueA match ‘aaa’ or ‘bbb’ and return not duplicated result.

Answer 1

Try this?

A_db_model.all().filter('valueA IN', ['aaa', 'bbb'])

or the equivalent GQL:

GqlQuery('SELECT * FROM A_db_model WHERE valueA IN :1', ['aaa', 'bbb'])
