django - djangoの管理パネルからサブユーザーを割り当てる

Question

私はdjango.dbインポートモデルのmodels.pyに次のものを持っています

class LabName(models.Model):
labsname=models.CharField(max_length=30)
def __unicode__(self):
 return self.labsname

class ComponentDescription(models.Model):
   lab_Title=models.ForeignKey('Labname')
    component_Name = models.CharField(max_length=30)
   description = models.CharField(max_length=20)
   purchased_Date = models.DateField()
   status = models.CharField(max_length=30)
   to_Do = models.CharField(max_length=30,blank=True) 
   remarks = models.CharField(max_length=30)

   def __unicode__(self):
   return self.component

私は私のadmin.pyに以下を持っています

from django.contrib import admin
from Lab_inventory.models import ComponentDescription,LabName
class ComponentDescriptionAdmin(admin.ModelAdmin):
list_display=('lab_Title','component_Name','description','qty','purchased_Date','status','to_Do','remarks')
   list_filter=('lab_Title','status','purchased_Date')
admin.site.register(LabName)
admin.site.register(ComponentDescription,ComponentDescriptionAdmin)

各ラボ名に異なるサブユーザーを割り当てるにはどうすればよいですか????
