[Solved]-How to display total record count against models in django admin


I would look into the models.Manager class. A subclass of Manager will allow you to add table-level functionality to your models. A Manager method can return any data you want and there is an interesting example in the Django DB API documentation. You may then be able to pull this into Admin by adding a admin inner class to your model.


from django import template
from django.db.models.loading import get_model

register = template.Library()

def get_model_count(admin_url):
  app_label, model_name = admin_url.split('/')[:2]
  return get_model(app_label, model_name, seed_cache=False).objects.count()

Then copy and override “/templates/admin/index.html” from “django’s contrib/admin/templates/index.html”.

At the top add:


Add the following call after the model name or wherever:

{% get_model_count model.admin_url %}

This fits nicely into this use case. You’re done!


I didn’t find any nice way to add count of models in the main admin page, but here is the solution that I finally use.

In short I compute the counts of each models in signals post_delete and post_save methods, store the variables in the custom request (in a map) and display it in the extended admin index.html by simply checking with an if for each desired models.

The extended templates/admin/index.html:

{% if model.perms.change %}
    <th scope="row"><a href="{{ model.admin_url }}">{{ model.name }} 
    {% if model.name == "Mymodel1_verbose_name_plural" %} ({{ MODELS_COUNT.Mymodel1}}) {% endif %}
{% else %}

My custom request in util/context_processors.py:

from myproject import settings

def myproject(request):
    return {
        'request' : request,
        'MODELS_COUNT' : settings.MODELS_COUNT

In my settings.py:

      'Mymodel1': None,
      'Mymodel2': None       


In myproject.__init__.py:

from django.db.models.signals import post_save, post_delete

def save_mymodel1_count(sender, instance=None, **kwargs):
    if kwargs['created']:
        settings.MODELS_COUNT['Mymodel1'] = Mymodel1.objects.count()
def delete_mymodel1_count(sender, instance=None, **kwargs):
    settings.MODELS_COUNT['Mymodel1'] = Mymodel1.objects.count()
settings.MODELS_COUNT['Mymodel1'] = Mymodel1.objects.count()

post_save.connect(save_mymodel1_count, sender=Mymodel1)
post_delete.connect(delete_mymodel1_count, sender=Mymodel1)

If you have lots of models, I suggest that you transform this in a more generic solution.
