Django: adding new admin_tags

/ Published in: Django

First: create a file under djangoapp/templatetags where you define your tags [e.g.: myadmin_tags.py]:

Second: create the html snippets that get loaded in those tags [e.g., personfactoid_info.html]:

Third: in mytemplates/admin/ modify change_form.html (if you don't have it just copy it from the django-admin app). You must add a placeholder for the new templatetags (probably you want to add it at the bottom of the page):

FOurth: create a new change_form.html in the same directory as above, but under your model template [e.g., mytemplates/admin/myapp/mymodel/change_form.html] so to override the behaviour just for that. The 'object_id' variable is passed by the admin template by default:

# FIRST:

from django import template 
from poms.pomsapp import models

# for People template

@register.inclusion_tag('admin/snippets/personfactoid_info.html') 
def display_personfactoids(person_id): 
    person = models.Person.objects.get(id__exact=person_id) 
    # factoids = models.Factoids.objects.filter(people=person)
    return { 'person': person }

## SECOND:

{% if person.assocfactoidperson_set.all %}

<b>Person associated to factoids:</b></br />

<table>
	  <tr>
	    <th>Record ID</th>
		<th>Type</th>
	    <th>Short Summary</th>
		<th>Role</th>
	    <th>Source</th>
	  </tr>

{% for a in person.assocfactoidperson_set.all %}
	  <tr>
	    <td>{{a.factoid.id}}</td>
		<td>{{a.factoid.get_right_subclass.0}}&#160;&#160;&#160;&#160;</td>
	    <td><a href="{% url factoid_detail a.factoid.id %}" title="click to show">{{a.factoid}}</a></td>
	    <td>{{a.role}}</td>
	    <td><a href="{% url source_detail a.factoid.sourcekey.id %}" title="click to show">{{a.factoid.sourcekey}}</a></td>
