Access "server-side" model methods on TastyPie Resource

I got this Resource and It's working fine and listing all the attributes from Employee's.

class EmployeeResource(ModelResource):
    journey = fields.ForeignKey(WorkJourney, 'work_journey')
    class Meta:
        queryset = Employee.objects.all()
        resource_name = 'employee'
        authentication = BasicAuthentication()

I have a method writen on Employee's model Class that lists the phone number's from an Employee (Terrible code imo., i think it should be an attribute but i can't change it).

@property
def phones(self):
    return u' / '.join([self.personal_phones or u'', self.institutional_phones or u''])

The point is to write a Resource method that access that Model method and list results with Employee's attributes..

If your Phone model look like this:

class Phone(models.Model)
     employee = models.ForeignKey(Employee, related_name=phones)

Then you can get list of all phones for the employee with defining in your EmployeeResource ToManyRelation with phones:

class EmployeeResource(ModelResource):
   phones = fields.ToManyField(PhoneResource, 'phones', full=True)
class Meta:
    queryset = Employee.objects.all()
    resource_name = 'employee'
    authentication = BasicAuthentication()

Also with override dehydrate method you can customize data what will be send to the client side.

Custom view is another solution for sending customize data.

You should be able to create it as a read-only field in your resource:

phones = fields.CharField(attribute='phones', readonly=True)

If you don't set readonly=True, Tastypie will try and set the field's value on insert/update.
