Hi again friends,
The total_likes have been hashtagged/commented in the LikeView.
The count is working perfectly in the admin and with every like it is added to the count because in the Post Detail View it is recognized, it is only not working in the LikeView.
I want to know why the hashtagged/commented part is wrong and how to resolve it.
class PostDetailView(DetailView):
model = Post
template_name = "post_detail.html"
def get_context_data(self, *args, **kwargs):
context = super(PostDetailView, self).get_context_data()
stuff = get_object_or_404(Post, id=self.kwargs['pk'])
total_likes = stuff.total_likes()
liked = False
if stuff.likes.filter(id=self.request.user.id).exists():
liked = True
context["total_likes"] = total_likes
context["liked"] = liked
return context
def LikeView(request):
post = get_object_or_404(Post, id=request.POST.get('id'))
# stuff = get_object_or_404(Post, id=self.kwargs['pk'])
# total_likes = stuff.total_likes()
liked = False
if post.likes.filter(id=request.user.id).exists():
post.likes.remove(request.user)
liked = False
else:
post.likes.add(request.user)
liked = True
context = {
# 'total_likes': total_likes,
'liked': liked,
'post': post
}
if request.is_ajax:
html = render_to_string('like_section.html', context, request=request)
return JsonResponse({'form': html})
class Post(models.Model): designer = models.ForeignKey(User, on_delete=models.CASCADE) design = models.ImageField( blank=False, null=True, upload_to=upload_design_to) title = models.CharField(max_length=100) date_posted = models.DateTimeField(default=timezone.now) likes = models.ManyToManyField( User, related_name='liked')
def total_likes(self):
return self.likes.count()
can you add print statement here on this function in your models & see def total_likes(self): print(self.likes.count()) return self.likes.count()

it is printing the number of counts correctly but I have to refresh the page
- ahmed.hisham87 4 years, 11 months agoso you mean count is getting into the view but it not reflecting using ajax right?

yes and the reason for this the LikeView function I have hashtagged the count as it is causing the like button not to work at all. Please check the LikeView function in the views and the hashtagged/commented codes
- ahmed.hisham87 4 years, 11 months agoUncomment the #likes in views .. "stuff = get_object_or_404(Post, id=self.kwargs['pk'])" change print(stuff) and see whether its returning data or not

nothing happens and i get this in the traceback stuff = get_object_or_404(Post, id=self.kwargs['pk'])
NameError: name 'self' is not defined
I got this error "NameError: name 'kwargs' is not defined" so I removed kwargs so I am getting now this error stuff = get_object_or_404(Post, id=['pk']): TypeError: int() argument must be a string, a bytes-like object or a number, not 'list'
- ahmed.hisham87 4 years, 11 months agothats true because you are not having args and *kwargs argument in your view right?.. So here is my recommendation, in your ajax call, make sure , you are sending the PK value or not. If yes then your URL is capturing that PK argument or not , and finally get the PK into view as an argument. If you are not clear then we will create some video and update here after sometime.

it is capturing pk, i just need to fix these 2 lines of codes to get the total_likes()
- ahmed.hisham87 4 years, 11 months agocan you add args , *kwargs in your view like this def Likeview(request, args, *kwargs)" after that print(args,kwargs)

We hope issue has been resolved.
Is total_likes() is a method in model? If yes, can you share the details?
