[xeroticikot]

Wagtail v7.1.1
Django v5.2.7
Python v3.13.9
OS - Windows 11
Package Manager - uv v0.9.0

Installation was successful - I have the following settings in settings/base.py -

WAGTAIL_AI = {
    "PROVIDERS": {
        "default": {
            "provider": "openai",
            "model": "gpt-5",
        },
    },
    "BACKENDS": {
        "default": {
            "CLASS": "wagtail_ai.ai.openai.OpenAIBackend",
            "CONFIG": {
                "MODEL_ID": "gpt-5",
                "TOKEN_LIMIT": 4096,
            },
        },
    },
}

but "python manage.py migrate" command throws the following error -

AttributeError: property 'limit' of 'BaseStorageDocumentQuerySet' object has no setter

it seems self.limit should be self._limit.

Thanks for the report! This looks like a django-ai-core issue, broken by an update in queryish: wagtail/queryish@434ca02. In the meantime you can try downgrading queryish to 0.2.

Thanks @xeroticikot - django-ai-core 0.1.5 has been published to resolve this issue.
