Permissions to view staff details per manager and per office

[Tommy]

Hi,

I am having difficulty getting my thoughts around my problem.

Given users (managerial, different levels) and depots/regional offices.

line_mangers should only see list of staff assigned to line_mangers group.

middle_managers should only see list of staff assigned from '1 to n' line_managers.

senior_manages should only see  list of staff assigned from '1 to n'  middle_managers in senior_manages depot/regional office.

executive_managers should see an overview of staff assigned to depots/regional offices.

I am looking at django-authority but it is unclear to me if this will work.

Q1. is what I seek row_object permissions, I am unsure of the terminology, I cannot get a understanding that I could explain to my grandmother. 

Q2. is it possible to have in my views.py a def that says something like

      if logged_in_user == manager_level and  is_assigned_office == office_n then view_only_staff_details == work_group and  region_office

models.py

class Employee(models.Model):

    first_name = models.CharField(max_length=75)

    surname = models.CharField(max_length=75)

    mname           = models.CharField(max_length=75, blank=True, null=True)

    def fullname(self):

        return '%s %s' % (self.first_name, self.surname)

    fullname = property(fullname)        

    def get_current_region(self):

eds = self.employeedynamic_set.filter(is_current=True)

if len(eds) > 1:

   return "Error more than one current depot for %s." % (self)

else:

   return eds[0].depot.region.name

class EmployeeDynamic(models.Model):

    employee = models.ForeignKey(Employee)    

    address = models.ForeignKey(Address)

    region         = models.ForeignKey(Region)

    depot         = models.ForeignKey(Depot)

    is_current = models.BooleanField()

I have sorted authenticated login by using django-userena
