[Fixed]-Django assignment_tag conditional

Firstly, that’s not how assignment tags work. You have never actually called the tag; if partner refers to a (non-existent) template variable named “partner”. You call an assignment tag by using it on its own along with a variable to assign it to:

{% partner as partner_value %}
{% if partner_value %}...{% endif %}

Secondly, that’s not how blocks work either. You can’t dynamically define blocks; they are part of the basic structure of a template, not something that is assigned during evaluation.

I accomplished this by using a context_processor (https://docs.djangoproject.com/en/1.7/ref/settings/#std:setting-TEMPLATE_CONTEXT_PROCESSORS)

Context Processor:

def partners(context):
    return {
        'partner': False
    }

Template:

{% block header %}
 {% if partner %}
  {% include 'includes/partner_header.djhtml' %}
 {% else %}
  {{ block.super }}
 {% endif %}
{% endblock header %}

{% block footer %}
  {% if partner %}
    {% include 'includes/partner_footer.djhtml' %}
  {% else %}
    {{ block.super }}
  {% endif %}
{% endblock footer %}
