Question

I am looking for way to clean up a template in django. A simple solution would be to break this up into multiple templates, but we do not want to do that.

We basically have the following

{%if data.some_state %}
    Display some markup
{% else %}
   {%if data.some_state_2 %}
       State 2 different html view 
   {% else %}
        {%if data.process_data %}
           Display some list of data
        {% else %}
           No Data to display!
       {% endif %} <!-- if data.process_data-->
   {% endif %} <!-- if data.some_state_2 -->
{% endif %} <!-- if data.some_state -->

So that is extremely confusing and hard to read. If I could do this in a “function” i would use if/else if or returns.

Is there a way in template language to do something like (stop_processing_template would tell the template we are done… ):

{%if data.some_state %}
    Display some markup
{% endif %}
{% django_stop_processing_template %}


{%if data.some_state_2 %}
       State 2 different view
{% endif %}
{% django_stop_processing_template %}

{%if data.process_data %}
           Display some list of data
{% endif %}
{% django_stop_processing_template %}

 No data provided !

You could use jinaj2 for templating that view (or the whole project), it supports if/elif/else branching:

{% if data.some_state %}
    Display some markup
{% elif data.some_state_2 %}
    State 2 different view
{% elif data.process_data %}
    Display some list of data
{% endif %}

There are a couple different packages which it easy use jinja2 in a django project, I’ve used both coffin and djinja for this.
