django orm queryset postgresql Python

I'm working on a project and hit a roadblock. I'm converting an old project and I'm working on a Django application where I need to filter a queryset based on two fields, `user` and `status`. However, I'm getting an empty result set even though I know that there are records that should match the query. Here’s the code I'm using: ```python from myapp.models import MyModel # Assuming these values are valid user_id = 1 # Existing user ID in the database status_value = 'active' # Trying to filter the queryset results = MyModel.objects.filter(user__id=user_id, status=status_value) ``` When I check the database directly, there are records with `user_id` of 1 and `status` set to 'active', so I don't understand why the queryset returns empty. I also tried breaking down the query to check each condition separately: ```python results_user = MyModel.objects.filter(user__id=user_id) results_status = MyModel.objects.filter(status=status_value) ``` Both `results_user` and `results_status` return non-empty querysets with matching records. This leads me to believe that there might be an issue with how I’m combining the filters. I have tried using `Q` objects as well: ```python from django.db.models import Q results_q = MyModel.objects.filter(Q(user__id=user_id) & Q(status=status_value)) ``` However, `results_q` is still returning empty. I’ve verified that `user_id` and `status_value` are indeed the expected types and values. Could there be something related to how the database is set up or any potential issues with the Django ORM querying that I might be missing? I’m using Django 4.0.3 and PostgreSQL as my database backend. I'm working in a Windows 10 environment. Any ideas how to fix this?
