Question

For 2 child template files inheriting a block, the {{ block.super }} does not resolve

Python 2.5.2, Django 1.0, Windows XP SP3

Sample skeleton code for files involved:

1. base.html
2. item_base.html
3. show_info_for_all_items.html
4. show_info_for_single_item.html

FILE : base.html

{% block content %} {% endblock %} 

FILE : item_base.html

{% extends 'base.html' %} {% block item_info %}        Item : {{ item.name }}<br/>     Price : {{ item.price }}<br/>    {% endblock %} 

FILE : show_info_for_all_items.html

{% extends 'item_base.html' %} {% block content %}     <h1>info on all items</h1>     <hr/>     {% for item in items %}         {% block item_info %}             {{ block.super }}         {% endblock %}         <hr/>     {% endfor %} {% endblock %} 

FILE : show_info_for_single_item.html

{% extends 'item_base.html' %} {% block content %}     <h1>info on single item</h1>         {% block item_info %}         {{ block.super }}     {% endblock %}   {% endblock %} 

show_info_for_all_items.html shows a list of items along with each item’s info.

show_info_for_single_item.html shows a single item with the item’s info.

show_info_for_all_items.html and show_info_for_single_item.html share same code for showing item info, so I moved it to item_base.html into block item_info

but the {{ block.super }} in show_info_for_all_items.html and show_info_for_single_item.html does not work. {{ block.super }} resolves as blank.

If I move the code back from block item_info in item_base.html into show_info_for_all_items.html and show_info_for_single_item.html it works but then I have to duplicate same block item_info code in 2 files.

If the block.super issue can not be solved, does Django offer something like INCLUDE => {% INCLUDE 'item_base.html' %} so blocks from a template file can be included ( instead of extends )

How do I avoid duplicating block item_info in both html files?

Answer 1

Does Django offer something like INCLUDE (…)

Yes!, just take a look at the documentation: include

Put the common code block in foo.html, and then, in each template:

{% include 'foo.html' %}
