Django-shop elasticsearch bug "Unexpected queryset model"

[tofbang]

Hi, i am on Debian 10 buster, python 3.7 I installed django-shop 1.2.4 demo and it works quite well. however a bug related to the elasticsearch_dsl library occurs when I use the site search module:

TypeError at /en/search/ Unexpected queryset model (should be: <class 'myshop.models.Product'>, got: <class 'myshop.models.Product'>)

Request Method: GET Request URL: http://www.cris-shiatsu.fr:9009/en/search/?q=test Django Version: 3.0.14 Exception Tyoe: TypeError Exception Value: Unexpected queryset model (should be: <class 'myshop.models.Product'>, got: <class 'myshop.models.Product'>) Exception Location: /usr/local/lib/python3.7/site-packages/django_elasticsearch_dsl/search.py in filter_queryset, line 26 /usr/local/bin/uwsgi Python version: 3.7.17

This bug refers to the following code in search.py ​​of the django-elasticsearch-dsl library:

def filter_queryset(self, queryset, keep_search_order=True):
        """
        Filter an existing django queryset using the elasticsearch result.
        It costs a query to the sql db.
        """
        s = self
        if s._model is not queryset.model:
            raise TypeError(
                'Unexpected queryset model '
                '(should be: %s, got: %s)' % (s._model, queryset.model)
            )

For the moment I commented out the error throwing condition and it works but i would like to understand and eventually resolve the problem without hacking the library

Please would you have an idea ?

Without more context, I can't name any reason.

Did I write the code you have shown?

sorry... i probably should ask to the library writer

I had the same problem, and I sent the solution to the library uploader, you can see it here:
