modified the notifications model. the sent_to is now a foreign key. now if we have a new type to be added, we can generate message and sub while creating notification. we can keep track of history using the role field in notification and task/sent_from

{% extends 'base.html' %}
{% block content %}
    List of all the tasks:<br />
    {% for task in task_list %}
        <a href="/task/view/tid={{ task.id }}">{{ task.title }}</a><br />
    {% endfor %}
{% endblock %}
