How to re-order apps and models in django admin?

When we register the models django automatically sorts apps by lexicographic order. But, we can do some hacks to order models and apps as we want.

Append below code in settings

from collections import OrderedDict

APP_ORDER = [
  ("app1", ["Model2", "Model1", "Model3"]),
  ("app2", ["Model2", "Model5", "Model3"]),
  ("app3", ["Model1", "Model6", "Model3"]),
] 

- APP_ORDER elements should be in the format (<app_name>, [<model1>, <model2>])

Now add a template tag which will create the order

• Let's add the below code to the template tag

from django import template
from django.conf import settings


register = template.Library()


def pop_and_get_app(apps, key, app_label):
    for index, app in enumerate(apps):
        if app[key] == app_label:
            obj = apps.pop(index)
            return obj
    return None

@register.filter
def sort_apps(apps):
    new_apps = []
    order = settings.APP_ORDER
    for app_label in order.keys():
        obj = pop_and_get_app(apps, "app_label", app_label)
        new_apps.append(obj) if obj else None
    apps = new_apps + apps
    for app in apps:
        models = app.get("models")
        app_label = app.get("app_label")
        new_models = []
        order_models = settings.APP_ORDER.get(app_label, [])
        for model in order_models:
            obj = pop_and_get_app(models, "object_name", model)
            new_models.append(obj) if obj else None
        models = new_models + models
        app["models"] = models
    return apps

override the django template admin/index.html

• We need to override the django admin template like below.

{% extends "admin/index.html" %}
{% block content %}
{% load i18n static admin_tags %}
<div id="content-main">

{% if app_list %}
    {% for app in app_list|sort_apps %}
        <div class="app-{{ app.app_label }} module">
        <table>
        <caption>
            <a href="{{ app.app_url }}" class="section" title="{% blocktrans with name=app.name %}Models in the {{ name }} application{% endblocktrans %}">{{ app.name }}</a>
        </caption>
        {% if app.app_label == 'manage_templates' %}
            <tr class="model-{{ model.object_name|lower }}">
                <th scope="row"><a href="{% url 'admin_www_list' %}">WWW</a></th>
            </tr>
        {% endif %}
        {% for model in app.models %}
            <tr class="model-{{ model.object_name|lower }}">
            {% if model.admin_url %}
                <th scope="row"><a href="{{ model.admin_url }}">{{ model.name }}</a></th>
            {% else %}
                <th scope="row">{{ model.name }}</th>
            {% endif %}

            {% if model.add_url %}
                <td><a href="{{ model.add_url }}" class="addlink">{% trans 'Add' %}</a></td>
            {% else %}
                <td>&nbsp;</td>
            {% endif %}

            {% if model.admin_url %}
                <td><a href="{{ model.admin_url }}" class="changelink">{% trans 'Change' %}</a></td>
            {% else %}
                <td>&nbsp;</td>
            {% endif %}
            </tr>
        {% endfor %}
        </tr>
        </table>
        </div>
    {% endfor %}
{% else %}
    <p>{% trans "You don't have permission to edit anything." %}</p>
{% endif %}
</div>
{% endblock %}
