Add chart with average basket price

[tvedeane]

This adds a new graph:

Testing it requires some data:

INSERT INTO "public"."statistics_processedpurchasefiles" ("id", "file_name", "processed_on") VALUES
(1, 'test', '2023-11-27 18:02:48.434505+00');
INSERT INTO "public"."statistics_purchasebasket" ("id", "purchase_date", "cashier", "purchase_counter", "gross_amount", "first_net_amount", "second_net_amount", "discount", "source_file_id", "tapir_user_id") VALUES
(3, '2023-11-27 18:02:48.434505+00', 1000, 2000, 28.88, 20, 20, 0, 1, 1066),
(4, '2023-11-01 18:02:48.434505+00', 1000, 2000, 28.88, 20, 20, 0, 1, 1066),
(5, '2023-10-27 18:02:48.434505+00', 1000, 2000, 28.88, 20, 20, 0, 1, 1066),
(6, '2023-10-27 18:02:48.434505+00', 1000, 2000, 128.88, 20, 20, 0, 1, 1066),
(7, '2023-07-27 18:02:48.434505+00', 1000, 2000, 28.88, 20, 20, 0, 1, 1066),
(8, '2023-07-27 18:02:48.434505+00', 1000, 2000, 28.88, 20, 20, 0, 1, 1065);

And then you can go to: http://localhost:8000/accounts/user/1066/

I'm actually not sure about this line - maybe it should be another permission?

I think PERMISSION_ACCOUNTS_VIEW is more appropriate.
Also, you can use the PermissionRequiredMixin to check for permissions, you can then reuse the same logic as the the TapirUserDetailView :

tapir/tapir/accounts/views.py

Lines 49 to 52 in 5ef7e14

	def get_permission_required(self):
	if self.request.user.pk == self.kwargs["pk"]:
	return []
	return [PERMISSION_ACCOUNTS_VIEW]

Thanks a lot for doing this 🙇

There was a confusion about what number we want to show, see the comments.
Otherwise, appart from a few small improvements, the structure is good 💯

About adding test data, usually we do it through the models .objects.create() in python code, we can easily execute arbitrary code with docker compose exec web poetry run python manage.py shell_plus. This way we are sure that Django finds the database as it expects it.
If you're feeling extra motivated, you could add stuff to tapir.utils.management.commands.generate_test_data_functions.reset_all_test_data, that's the function that generates our test data.

Thanks again for contributing, it's great 🎉

[tvedeane]

I applied all the suggestions. Thanks for the review :)
