Question

我有视图功能，根据我给出的数据过滤对象，如果数据库中不存在过滤后的对象，则将对象添加到DB（我还没有编写添加功能）。如果已存在则显示错误。我使用ajax post请求从模板中获取数据。

#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} ----我从ajax post request获取这些数据，
userid，project_id，db_profileid，setasdefaultproject（boolean）} -----模型字段

当我尝试检查我的elif条件时，我在控制台＆＃34; aaaa＆＃34;（其他部分）中获得输出。 elif怎么了？

这里的前：

x = 4

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

django视图中的elif条件
