Hello all! I'm trying to flter query that returns rows from the table along with only elements from the ArrayField that overlap a specified DateTimeTZRange. Example:
import datetime from psycopg2.extras import DateTimeTZRange from django.db import models from django.contrib.postgres.fields import ArrayField, DateTimeRangeField class MyModel(models.Model): myfield = ArrayField(DateTimeRangeField()) d1 = datetime.datetime.now() d2 = datetime.datetime.now() + datetime.timedelta(days=1) d3 = datetime.datetime.now() + datetime.timedelta(days=5) d4 = datetime.datetime.now() + datetime.timedelta(days=7) MyModel.objects.create(myfield=[DateTimeTZRange(d1, d2), DateTimeTZRange(d3, d4)]) Filtering by each element of array works as expected: search_from = datetime.datetime.now() search_to = datetime.datetime.now() + datetime.timedelta(hours=8) MyModel.objects.filter(myfield__0__overlap=DateTimeTZRange(search_from, search_to)) <QuerySet [<MyModel: MyModel>]> MyModel.objects.filter(myfield__1__overlap=DateTimeTZRange(search_from, search_to)) <QuerySet []> But how to filter by all array fields? MyModel.objects.filter(myfield__overlap__overlap=DateTimeTZRange(search_from , search_to)) ... FieldError: Unsupported lookup 'overlap' for ArrayField or join on the field not permitted. MyModel.objects.filter(myfield__0_100000__overlap=DateTimeTZRange( search_from, search_to)) <QuerySet []> Thanks for any help. -- You received this message because you are subscribed to the Google Groups "Django users" group.
