For example I have a model with json field:
{{{
class MyModel():
model_field = JsonField()
}}}
I create 3 records in db:
{{{
x1 = MyModel(model_field={json_field=''}).save()
x2 = MyModel(model_field={json_field=None}).save()
x3 = MyModel(model_field={json_field='foobar'}).save()
}}}
And then I want for filter all records which contains non-empty json_field
like this:
{{{
MyModel.objects.exclude(model_field__json_field__in=['', None])
}}}
I expect only x3 record in result, but x2 presents too. This is also
wrong:
{{{
MyModel.objects.exclude(model_field__json_field='').exclude(model_field__json_field__isnull=True)
}}}
Only this filter works as expected:
{{{
MyModel.objects.exclude(model_field__json_field='').exclude(model_field__json_field=None)
}}}
