Do queries made instantiating a form not show up in db.connection.queries?

[Jonathan Berger]

Hi Django Users,

I'm a moderate-level user of Django and trying to determine if I've found a bug.

Per the db and model FAQ: expected behavior is that 'connection.queries' should contain a list of all SQL queries made by an app.

I'm finding actual behavior for a Form subclass that has a ModelMultipleChoiceField with a default queryset, does not add that query to 'connection.queries'. This violates expected behavior.

Am I misunderstanding something or is this a bug?

Thanks,

Jonathan

https://docs.djangoproject.com/en/2.1/ref/forms/fields/#django.forms.ModelChoiceField.queryset notes the queryset is "evaluated when the form is rendered." ...are you rendering the form or just instantiating it (per the subject)?

Thank you!

I was looking at the value of 'connection.queries' before rendering the form.
