elif condition in django view - django

Question

I'm having view function which filters object according to the data I give and if that filtered object does not exist in the database it adds the object to DB(i didn't write add function yet). Shows error if it exists already. I'm getting data from a template using ajax post request.
#view.py
#csrf_exempt
def setUserInDB(request):
if request.method=="POST":
if request.POST.get('pname','u_id'):
pname = request.POST.get('pname')
u_id = request.POST.get('u_id')
user = userprofile.objects.get(pk=u_id)
pid = Project.objects.get(title=pname)
else:
u_id = None
pname = None
if request.POST.get('db_id','chkbox'):
db_id = request.POST.get('db_id')
db = Db_profile.objects.get(pk=db_id)
chkbox = request.POST.get('chkbox')
print chkbox
else:
db_id = None
chkbox = None
if Projectwiseusersetup.objects.filter(userid=user,project_id=pid,
db_profileid= db,setasdefaultproject=chkbox):
print "already exist"
elif (((Projectwiseusersetup.objects.filter(userid = user,project_id =
pid,db_profileid=db,setasdefaultproject=False)).exists()) and
(chkbox==True)):
print "FtoT"
elif Projectwiseusersetup.objects.filter(userid = user,project_id =
pid,db_profileid=db,setasdefaultproject=True) and chkbox==False:
print "TtoF"
else:
print "aaaa"
user,pid,db,chkbox }---- i'm getting these data from ajax post request,
userid, project_id, db_profileid, setasdefaultproject(boolean) }----- model fields
when I try to check my elif condition, i'm getting output in console "aaaa"(else part). what is wrong with elif?

Here the ex:
x = 4
if x == 1:
print ("1")
elif (x == 2):
print("2")
elif (x == 3):
print("3")
else:
print("4")
