I am currently trying to create a like button for my posts in Django
I have reached to the part where I can add a like but I am facing
difficulty writing the code related to the view which linking the
PostListView if there is user who liked it or not. I am getting an error:
page Error 404 although everything is correct
this the views:
class PostListView(ListView):
model = Post
template_name = "score.html"
ordering = ['-date_posted']
context_object_name = 'posts'
queryset = Post.objects.filter(admin_approved=True)
paginate_by = 5
def get_context_data(self, **kwargs):
post = get_object_or_404(Post, id=self.request.POST.get('post_id'))
context = super(PostListView, self).get_context_data(**kwargs)
context['posts'][0].likes.filter(id=self.request.user.id).exists()
is_liked = False
if post.likes.filter(id=self.request.user.id).exists():
is_liked = True
context = {'post': post,
'is_like': is_liked,
}
return context
def like_post(request):
post = get_object_or_404(Post, id=request.POST.get('post_id'))
is_liked = False
if post.likes.filter(id=request.user.id).exists():
posts.likes.remove(request.user)
is_liked = False
else:
post.likes.add(request.user)
is_liked = True
return HttpResponseRedirect(post.get_absolute_url())
This is the model
class Post(models.Model):
designer = models.ForeignKey(User, on_delete=models.CASCADE)
title = models.CharField(max_length=100)
date_posted = models.DateTimeField(default=timezone.now)
likes = models.ManyToManyField(User, blank=True, related_name='likes')
def __str__(self):
return self.title
Here is the
path('like/', like_post, name='like_post'),
here is the template:
{% extends "base.html"%} {% block content %} {% for post in posts %}
<div style="padding-top: 200 px;"><strong>{{post.title}}</strong></div>
<form action="{% url 'score:like_post'%}" method="POST" class="ui form">
{% csrf_token %} {% if is_like %}
<input type="hidden" name="post_id" value="{{post.id}}" />
<button class="ui button positive" type="submit">Unlike</button>
{% else %}
<button class="ui button negative" type="submit">Like</button>
{% endif %}</form><strong>Likes </strong>
{% endfor %} {% endblock content %}
