These Are the Months Of Our Lives

Behold! An update!

I've just added month-based archiving. It's just another wrapper around a generic view. I did write a couple template tags to help build my list of archive links the way I wanted to. I wanted to present a flat list of months with posts in them, leaving out the year-archive pages entirely.

Here's the template code I wrote to present the list of archive month links on the home page: 

<ul class="nav-bar">
    <li>Archive: </li>
{% for d in date_list|months_with_content %}
    {% with d|date:"F" as m %}
        <li><a href="{% url blog_archive_month year=d.year,month=m.lower %}">{{ m }} {{ d.year }}</a></li>
    {% endwith %}
{% endfor %}
</ul>

For the month archive template I wrote a different block of code to link to list the current month and the months on either side, since that's what the archive_month view affords me 

<ul class="nav-bar">
    <li>Archive: </li>
 
    {% if previous_month|has_posts_in_month %}
        {% with previous_month|date:"F" as month_str %}
    <li><a href="{% url blog_archive_month year=previous_month.year,month=month_str.lower %}">{{ month_str }} {{ previous_month.year }}</a></li>
        {% endwith %}
    {% endif %}
 
    {% with month|date:"F" as month_str %}
    <li><a class="active" href="{% url blog_archive_month year=month.year,month=month_str.lower %}">{{ month_str }} {{ month.year }}</a></li>
    {% endwith %}
 
    {% if next_month|has_posts_in_month %}
        {% with next_month|date:"F" as month_str %}
    <li><a href="{% url blog_archive_month year=next_month.year,month=month_str.lower %}">{{ month_str }} {{ next_month.year }}</a></li>
        {% endwith %}
    {% endif %}
</ul>

And finally, here are the two template tags I wrote that are used in that template code: 

@register.filter
def months_with_content(date_list):
    """
    Returns a list of months where there are blog posts within the year range
    provided.
 
    Syntax:
 
        {{ date_list|months_with_content }}
 
    """
    dates = []
    for year_date in date_list:
        dates += list(BlogPost.objects.filter(pub_date__year=year_date.year).dates('pub_date', 'month'))
    return dates
 

@register.filter
def has_posts_in_month(date):
    if not date:
        return False
    return BlogPost.objects.filter(pub_date__year=date.year, pub_date__month=date.month).count() > 0

Can you tell I'm a back-end programmer from that beastly Django templating?
