Comment (by Pal): Replying to [comment:2 Simon Charette]: > Could you provide a traceback and more details about how ''it fails''? > > Does it happen when you define a model using `ArrayField(CharField())`, when performing a query annotation? Yes. When I defined the model as shown in the documentation at https://docs.djangoproject.com/en/2.0/ref/contrib/postgres/fields /#querying-arrayfield , the query fails. But if I change models.CharField to models.TextField, the query succeeds. Here are the error statements from apache2 error log: psycopg2.ProgrammingError: operator does not exist: text[] @> character varying[] django.db.utils.ProgrammingError: operator does not exist: text[] @> character varying[] May be we need to change the documentation to reflect the change above. Thanks. -- Ticket URL: <https://code.djangoproject.com/ticket/29171#comment:3> Django <https://code.djangoproject.com/> The Web framework for perfectionists with deadlines. -- You received this message because you are subscribed to the Google Groups "Django updates" group.
