CBV – DayArchiveView

From Classy Class Based Views DayArchiveView

List of objects published on a given day.

Attributes

There are six new attributes to review here … well really 3 new ones and then a formatting attribute for each of these 3:

• day: The day to be viewed
• day_format: The format of the day to be passed. Defaults to %d
• month: The month to be viewed
• month_format: The format of the month to be passed. Defaults to %b
• year: The year to be viewed
• year_format: The format of the year to be passed. Defaults to %Y

Required Attributes

• day
• month
• year
• date_field: The field that holds the date that will drive every else. We saw this in ArciveIndexView

Additionally you also need model or queryset

The day, month, and year can be passed via urls.py so that they do’t need to be specified in the view itself.

Example:

views.py

class myDayArchiveView(DayArchiveView):
    month_format = '%m'
    date_field = 'post_date'
    queryset = Person.objects.all()
    context_object_name = 'person'
    paginate_by = 10
    page_kwarg = 'name'

urls.py

path('day_archive_view/<int:year>/<int:month>/<int:day>/', views.myDayArchiveView.as_view(), name='day_archive_view'),

<model_name>_archiveday.html

{% extends 'base.html' %}

    <h1>
    {% block title %}
        {{ title }}
    {% endblock %}
    </h1>


{% block content %}
    <div>
        <ul>
        {% for p in person %}
            <li><a href="{% url 'rango:detail_view' p.first_name %}">{{ p.post_date }}: {{ p.first_name }} {{ p.last_name }}</a></li>
        {% endfor %}
        </ul>
    </div>
    <div class="">
    {% if is_paginated %}
      <ul class="mui-list--inline mui--text-body2">
        {% if page_obj.has_previous %}
          <li><a href="?name={{ page_obj.previous_page_number }}">&laquo;</a></li>
        {% else %}
          <li class="disabled"><span>&laquo;</span></li>
        {% endif %}
        {% for i in paginator.page_range %}
          {% if page_obj.number == i %}
            <li class="active"><span>{{ i }} <span class="sr-only">(current)</span></span></li>
          {% else %}
            <li><a href="?name={{ i }}">{{ i }}</a></li>
          {% endif %}
        {% endfor %}
        {% if page_obj.has_next %}
          <li><a href="?name={{ page_obj.next_page_number }}">&raquo;</a></li>
        {% else %}
          <li class="disabled"><span>&raquo;</span></li>
        {% endif %}
      </ul>
    {% endif %}
    </div>
{% endblock %}

Conclusion

If you have date based content a great tool to use and again super easy to implement.

There are other time based CBV for Today, Date, Week, Month, and Year. They all do the same thing (generally) so I won’t review those.
