How to retrieve a BitField flag value in a queryset filter using values_list.

[0xLuz]

I have a model with BitField like this:

class MyModel(models.Model):
        notifications = BitField(flags=('facebook', 'email'))

I would like to filter my model just retrieving the values, but the BitField is unable to return the flag values independently. I have unsuccessfully tried:

MyModel.objects.all().values_list(
     'id', 'notifications__facebook', 'notification__email'
)

Is there a way to make it work?

Note that a bitfield is transmitted over the wire as just a single 32-bit word, and I expect Python to do a similar type of work to make what you're asking for as . So I'm not sure there's an optimization to be had here, though it could simplify code to be able to marshall things that way.

I don't think that syntax makes sense; it would conflict with another field called notifications_facebook. I could imagine e.g. notifications__facebook being valid.

HI @timabbott I used the __, It was just a typo on my question. I fixed it, but the question is still persisting...
