I Solved it :
def resultats(request,id=None):
etudiant = MyUser.objects.all
moy = MyUser.objects.all().annotate(moyenne =(F('moyenne_s1')+F('moyenne_s2'))/2).filter(moyenne__gt=11.99,specialite='SI')
moy1 = MyUser.objects.all().annotate(moyenne =(F('moyenne_s1')+F('moyenne_s2'))/2).filter(moyenne__lt=11.99)
if moy1 :
moy1.specialite = 'ISIL'
moy1.update(specialite='ISIL')
if id:
pr = get_object_or_404(MyUser,id=id)
else:
pr = request.user
context = {
'etudiant':etudiant,
'profile':pr,
'etud_si':moy,
'etud_isil':moy1
}
return render(request,'resultats.html',context)
