Using OSIS-Comment

osis_comment is a small utility package that allows user to comment on objects within a Django application.

This object's comment is then exposed via a UX-friendly widget that allows viewing, adding, editing and deleting comments.

Prepare your classes

Before being able to create comment entries, you will need to prepare your model classes.

To do so, just add the CommentDeleteMixin to the classes that will have comments on their objects instances ;

• Import and declare the mixin :

from django.db import models
from osis_comment.models import CommentDeleteMixin
 
class MyClass(CommentDeleteMixin, models.Model):
    ...

Add an API View for an object's comments

To add CRUD behavior on a given object, you must implement an API view that will be called by the widget, you are free to put any view permission on it. As for the add, edit and delete, you can override the methods as you wish, by default all permissions are allowed:

# In your views
from osis_comment.contrib.mixins import CommentEntryAPIMixin
from osis_role.contrib.views import PermissionRequiredMixin


class MyModuleCommentView(CommentEntryAPIMixin):
  def has_add_permission(self):
    return False

  def has_change_permission(self, comment):
    return self.request.user.person == comment.author

  def has_delete_permission(self, comment):
    return self.request.user.person == comment.author


# In your urls
from django.urls import path

urlpatterns = [
  path("<uuid:uuid>/", MyModuleCommentView.as_view(), name="some-test"),
]

Then to render the widget for an object, include the CSS and JS file while adding a div.comment-viewer element to your DOM:

{% block style %}
  <link href="{% static 'osis_comment/osis-comment.css' %}" rel="stylesheet"/>
{% endblock style %}

{% block content %}
  <div class="comment-viewer" data-url="{% url 'some-test' object.uuid %}"></div>
{% endblock %}

{% block script %}
  <script type="text/javascript" src="https://unpkg.com/vue@2/dist/vue.min.js"></script>
  <script type="text/javascript" src="https://unpkg.com/[email protected]/dist/vue-i18n.min.js"></script>
  <script type="text/javascript" src="{% static 'osis_comment/osis-comment.umd.min.js' %}"></script>
{% endblock %}
