Steps to Reproduce

1. Ensure at least some tags exist
2. Create simple script and define MultiObjectVar with default value (Queryset, like default=Tag.objects.filter(...))

from extras.scripts import Script, MultiObjectVar
from extras.models import Tag

class TestMultiObjectVarDefault(Script):
    class Meta:
        name = "TestMultiObjectVarDefault"

    tags = MultiObjectVar(
        label="Tags",
        model=Tag,
        required=True,
        default=Tag.objects.all()[:2]
    )

    def run(self, data, commit):
        pass

3. Go to script page, field is populated with values

4. Go to /extras/scripts and click "Run Script" or "Run Again" from scripts list directly

5. Field is not populated with values, get error "<RestrictedQuerySet ... is not a valid value"

Reproduced on public demo stand

Expected Behavior

Expected similar behaviour in both cases, one of:

1. You cannot use queryset as default value
2. You can use queryset as default value

Observed Behavior

You can use queryset as default value if you first go to script page
You can not use queryset as default value if you launch script from /extras/scripts page

The error message is telling you what's wrong. You need to past a list of tag IDs, not a queryset, which cannot be serialized as form data.

Its ok if i need to pass list of tag IDs, problem is that default value being queryset is working if i launch script from script page (click script and field is populated from default value, which is queryset) and is not working if it is launched from script list page, same form opens, but there is error. So i observe different behaviour depending how i launch script.

• That way queryset as default is working

• That way it is not working
