I have written a function of django ajax. If you don't know what's wrong, you can't execute successfully?

the function to be implemented is that when viewing a resource, you need to deduct the points of the resource, display the real resource address, and call ajax, to implement no refresh

models.py
class Zyuser_MeiMei (models.Model):

author = models.ForeignKey(settings.AUTH_USER_MODEL, null=True)
mmei = models.ForeignKey("MeiMei", verbose_name="", null=True)
mark = models.BooleanField(default =False, verbose_name=_(u""))

def __unicode__(self):
    return self.author.username
class Meta:
    verbose_name_plural = u"vip"

views.py

< H1 > users view deduction function < / H1 >

@ login_required
@ csrf_exempt
def look_mm (request, mm_id):

author = request.user
mm = MeiMei.objects.get(id = mm_id)
print "adsfasdf"
if author.levels < mm.level:
    -sharpraise ","
    -sharp!
    return render(request,"meimei/jifen.html")
else:
    User.objects.filter(username = author.username).update(levels=F("levels") - mm.level)
    u_m = Zyuser_MeiMei.objects.update_or_create(author=author, mmei=mm)
    u_m.mark = True
print "aaaaaaaaaa"
return u_m

.html page

Click to view resources

< script src= " http://libs.baidu.com/jquery/.;></script>
< script type= "text/javascript" >
function vip_chakan (o, meimei.id) {

    $.ajax({
        type:"POST",
        url:"/look_mm/"+{{meimei.id}}+"/",
        dataType:"json",
        processData:false,  // jquery
        contentType:false,  // jquery
        success:function(u_m){
            alert(u_m.mark);
        }
        error:function(){
            alert("!")
        }
    });

}
< / script >

url.py
url (r"^ look _ mm/ (? P < mm_id > [0-9] +) / $", login_required (look_mm), name="lookmm"),

I don"t know what went wrong. Which views.py function is always not executed?

@login_required @csrf_exempt def look_mm(request, mm_id): author = request.user ret = {'status': 0, 'u_m': ''} mm = MeiMei.objects.get(id = mm_id) try: User.objects.filter(username = author.username).update(levels=F('levels') - mm.level) Zyuser_MeiMei.objects.update_or_create(author=author, mmei=mm) ret['status'] = 1 ret['u_m'] = True except: return JsonResponse(ret)

<script src="http://libs.baidu.com/jquery/2.1.4/jquery.min.js"></script> <script type="text/javascript"> function vip_chakan(){ $.ajax({ type:"POST", url:"/look_mm/"+{{meimei.id}}+"/", dataType:"json", processData:false, // jquery contentType:false, // jquery success:function(data, status){ if(data.status == 1){ $("-sharpchakan").css('display','none'); $("-sharpokchakan").css('display','inline'); } } }); } </script>
