LIKE button in a Django project-CodePudding

There is a view in the Django project (a paginated blog) that is responsible for how likes work. It has one drawback: when a user likes a post, it is redirected to the main page of the site. How can I fix this so that the user would remain on the page where they liked.

views.py

class AddLikeView(View):
     def post(self, request, *args, **kwargs):
         blog_post_id = int(request.POST.get('blog_post_id'))
         user_id = int(request.POST.get('user_id'))
         url_from = request.POST.get('url_from')

         user_inst = User.objects.get(id=user_id)
         blog_post_inst = News.objects.get(id=blog_post_id)

         try:
             blog_like_inst = BlogLikes.objects.get(blog_post=blog_post_inst, liked_by=user_inst)
         except Exception as e:
              blog_like = BlogLikes(blog_post=blog_post_inst,
                          liked_by=user_inst,
                          like=True)
              blog_like.save()
         return redirect(url_from)

template.py

<form action="{% if not is_liked_bool %}{% url 'add' %}{% else %}{% url 'remove' %}{% endif %}" method="post">
{% csrf_token %}
<input type="hidden" name="blog_post_id" value="{{ blog_post_id }}">
<input type="hidden" name="user_id" value="{% if user.is_authenticated %}{{ request.user.id }}{% else %}None{% endif %}">
<input type="hidden" name="url_from" value="{{ request.path }}">

{% if is_liked_bool %}
    <input type="hidden" name="blog_likes_id" value="{{ blog_likes_id }}">
{% endif %}



<button type="submit" class="btn btn-success">
    {% if not is_liked_bool %}
        <i class="fi-xnluxl-heart">♥</i>
    {% else %}
        <i class="fi-xnluxl-heart-solid">♥</i>
    {% endif %}
    <span class="likes-qty">{{ likes_counter }}</span>
</button>

CodePudding user response：

I think you should check the url_from field first. Just print it and if it's wrong, you should change the {{request.path}} field in your template.

You can try this:

{{ request.get_full_path }}

And also if I remember correctly, you can access the path with request.path in your view and no need to send path via template.
