I know this question has been asked on SO before however I have tried everything that has been suggested in the answers and none seem to work.
Problem: I have a model class called 'Accomm' in my Django project where I have a number of objects stored. On the web pages where I try to retrieve one or more instances of 'Accomm' then the following error is raised...
ProgrammingError at /
column objects_accomm.description does not exist
LINE 1: ...omm"."id", "objects_accomm"."mapped_location_id", "objects_a...
This problem started to occur when I migrated a new field 'description' to the 'Accomm' model.
Tried solutions: I have attempted to do the following things... clear all Django migrations (using the --zero and --empty commands); clear the database (PostgreSQL 10); clear both the migrations and database; changing the name of my database in the Django project settings.py file. None of these seem to work. I have also followed tutorials here, here and here.

Edit: Models.py for 'Accomm':

description=models.CharField(max_length=1000,null=True,blank=True)

Views.py:
def home(request):
user = request.user
accomm = Accomm.objects.annotate(img_count=models.Count('a_image')).filter(img_count__gte=1)[:6]
return render(request, 'home.html', {'accomm':accomm})
Any other ideas besides the solutions proposed here?
