Django easy comments

This is a Django application that allows for the simple creation of a threaded commenting system. Commenters can reply both to the original item, and reply to other comments as well.

The application can be easily extended by other modules.

Installation

Install the package via pip: pip install django-easycomments It's preferred to install the module in a virtual environment.

Configuration

Add the following to settings.py:

INSTALLED_APPS += (
    'django-easycomments'
)

COMMENTS_APP = 'django-easycomments'

---

models.py:

Add these properties at the end of your model that you want to comment on.

  from django.contrib.contenttypes.models import ContentType
  
  @property
    def comments(self):
        instance = self
        qs = Comment.objects.filter_by_instance(instance)
        return qs
        
  @property
  def get_content_type(self):
      instance = self
      content_type = ContentType.objects.get_for_model(instance.__class__)
      return content_type

---

views.py:

Integrate this code in your (e.g. post_detail) view to add your model comment form and threads. Instance is the model that you want to comment (e.g. post)

from comments.models import Comment
from comments.forms import CommentForm

initial_data = {
          "content_type": instance.get_content_type, 
          "object_id": instance.id
  }
  
form = CommentForm(request.POST or None, initial=initial_data)
if form.is_valid():
    c_type = form.cleaned_data.get("content_type")
    content_type = ContentType.objects.get(model=c_type)
    obj_id = form.cleaned_data.get('object_id')
    content_data = form.cleaned_data.get("content")
    parent_obj = None
    try:
        parent_id = int(request.POST.get("parent_id"))
    except:
        parent_id = None

    if parent_id:
        parent_qs = Comment.objects.filter(id=parent_id)
        if parent_qs.exists() and parent_qs.count() == 1 :
            parent_obj = parent_qs.first()

    new_comment, created = Comment.objects.get_or_create(
                        user = request.user,
                        content_type= content_type,
                        object_id = obj_id,
                        content = content_data,
                        parent = parent_obj,
                        )
    return HttpResponseRedirect(new_comment.content_object.get_absolute_url()) 
    
    
comments = Comment.objects.filter_by_instance(instance)   
context={
      "instance" : instance,
      "comments" : comments,
      "comment_form":form,
      }
 return render(request, "app_name/post_detail.html",context)

---

Provide a template (e.g. post_detail.html) that displays the comments for the object (e.g. article or blog entry):

  {% if request.user.is_authenticated %}
      <p>Comment</p>
      <form method="POST"> {% csrf_token %}
        {{ comment_form|crispy }}
        <input type='submit' value='Comment' class='btn btn-outline-success'>
      </form>
  {% endif %}

  {% for comment in comments %}
  
        {{ comment.content }}
        <footer class="blockquote-footer">{{ comment.user }} | {{ comment.timestamp|timesince }} ago | {% if comment.children.count > 0 %}{{ comment.children.count }} Comment{% if comment.children.count > 1 %}s{% endif %} | {% endif %} <a class='comment-reply-btn' href='#'> Reply </a> | <a href='{{ comment.get_absolute_url }}'>Thread</a></footer>

        {% for child_comment in comment.children %}
              {{ child_comment.content }}
        {% endfor %}

        {% if request.user.is_authenticated %}
          <form method="POST"> {% csrf_token %}
            {{ comment_form|crispy }}
            <input type='hidden' name='parent_id' value='{{ comment.id }}'>
            <input type='submit' value='Reply' class='btn btn-outline-dark'>
          </form>
        {% else %}
          <p>You must login to comment </p>
        {% endif %}

        {% empty %}
          <p >No comments posted yet.</p>

{% endfor %}
