[Answered ]-TypeError at /check 'ModelBase' object is not iterable in django

You are using queryset object to fetch class’s attribute. It needs an instance to use class’s attribute. Just change your check method to the following:

def check(request):
    dishs = dish.objects.all()
    for dish in dishs:
        print(dish.dish_name)
    params = {'dish': dishs}
    return render(request, 
    "card/check.html", params)
