Using *django-sortable-listview* package, I'm using *SortableListView *to
sort out all the model fields. In my case, more than model fields, I want
to sort it out by model method too.
Models.py
class Employee(models.Model):
name = models.CharField()
designation = models.CharField()
company = models.ForeignKey(Company)
team = models.CharField()
# method
def team_count(self):
count = len(Employee.objects.filter(team=self.team))
return count
>
>
> Views.py
class EmployeeListView(SortableListView, generic.list.ListView):
allowed_sort_fields = {'name': {'default_direction': '',
'verbose_name': 'Employee Name'},
'designation': {'default_direction': '',
'verbose_name': 'Designation'},
'team': {'default_direction': '',
'verbose_name': 'Team Name'},
'team_count()': {'default_direction': '',
'verbose_name': 'No of Team members'}}
default_sort_field = 'name'
queryset = Employee.objects.all()
paginate_by = 10

On the above example, I want to list out Employee name, designation, team
name and count of team members.
Anybody help me to sort 'team_count' column?
