Im trying to make a table to show product prices over a year.

Here is what Im doing on a YearArchiveView:

{% regroup object_list|dictsort:"store.id" by store as store_list %}

<ul>

{% for store in store_list %}

<li>{{ store.grouper }}

{% regroup store.list|dictsort:"product" by product as product_list %}

<ul>

{% for product in product_list %}

<li>{{ product.grouper }}

<ul>

{% for item in product.list|dictsort:"date" %}

<li>{{ item.price }} - {{ item.date|date }}</li>

{% endfor %}

</ul>

</li>

{% endfor %}

</ul>

</li>

{% endfor %}

</ul>

This gives me this output:

<ul>

<li>Apple

<ul>

<li>iMac

<ul>

</ul>

</li>

</ul>

</li>

</ul>

Is it possible to display a default value if there is not a date entry in a month? Like this:

<ul>

<li>Apple

<ul>

<li>iMac

<ul>

</ul>

</li>

</ul>

</li>

</ul>
