Add simple interactions to the otherwise static django admin.



  • Install the package via pip:

    pip install django-dynamic-admin-forms

    or via pipenv:

    pipenv install django-dynamic-admin-forms

  • Add the module to INSTALLED_APPS:


    Ensure that the dynamic_admin_forms comes before the default django.contrib.admin in the list of installed apps, because otherwise the templates, which are overwritten by dynamic_admin_forms won't be found.

  • Ensure that the dynamic_admin_forms templates are found via using APP_DIRS setting:

            'BACKEND': 'django.template.backends.django.DjangoTemplates',
            'APP_DIRS': True,
  • Run python collectstatic to include this apps Javascript code in your settings.STATIC_ROOT directory


  • Add the dynamic_admin_forms.DynamicModelAdminMixin to your admin classes

  • Add the dynamic_admin_forms.urls to your urls

    from django.contrib import admin
    from django.urls import path, include
    urlpatterns = [
      path("dynamic-admin-form/", include("dynamic_admin_forms.urls")),
  • In addition to the standard fields declaration, specify a list of dynamic_fields

  • For each dynamic field, add a method get_dynamic_{field_name}_field to the admin

    • Input: data: Dict[str, Any] - the cleaned form data
    • Output:
      • queryset: Optional[Queryset] - The values to select from
      • value: Any - The value, the field should have (must be compatible to the field type)
      • hidden: Bool - True, if field should be hidden
  • A rather non-sensical example:

    from django.contrib import admin
    from .models import MyModel
    from dynamic_admin_forms.admin import DynamicModelAdminMixin
    class MyModelAdmin(DynamicModelAdminMixin, admin.ModelAdmin):
      fields = ("name", "city")
      dynamic_fields = ("city",)
      def get_dynamic_city_field(self, data):
        # automatically choose first city that matches first letter of name 
        name = data.get("name")
        if not name:
          queryset = City.objects.all()
          value = data.get("city")
          queryset = City.objects.filter(name__startswith=name[0])
          value = queryset.first()
        hidden = not queryset.exists()
        return queryset, value, hidden

How it works

Whenever a dynamic form changes, an event handler makes a request to a special endpoint, which returns new HTML to swap into the existing form. This new HTML is directly generated by django.contrib.admin, so we only have to set the outerHTML of the correct HTML elements to update the form.


  • does not work in conjunction with inlines
  • does not validate that the selected value is really part of the original queryset
    • if anybody can modify your DOM, they could potentially inject invalid values
    • you have to write Model.clean() methods to guard against that
  • only tested with Django 3.2


This project uses the flit package to publish to PyPI. Thus publishing should be as easy as running

flit publish

To publish to TestPyPI use the following ensure that you have set up your .pypirc as shown here and use the following command:

flit publish --repository testpypi


For local development, create a virtual environment in the testproj folder:

$ cd testproj
$ python3 -m venv .venv
$ source .venv/bin/activate
$ cd ..
$ flit install --symlink

Now the package should be available in your virtual environment and any changes should be directly visible.

Alternatively, simply copy the directory dynamic_admin_forms into any normal django project, so that the python interpreter finds the local version instead of the installed (old) version.

Running E2E tests

To run end-to-end tests locally:

$ cd testproj
$ python runserver &  # start server
$ python loaddata fixtures/fixtures-dev.json
$ cd ../e2e
$ yarn install  # or npm install (only needed first time)
$ yarn cypress  # or npm run cypress
