Django Auto Admin Fieldsets

A Django utility for automatically handling unspecified fields in ModelAdmin fieldsets.

Installation

pip install django-auto-admin-fieldsets

Features

• Automatically add unspecified model fields to a designated placeholder in Django admin fieldsets
• Works with all field types, including many-to-many fields
• Respects exclude and readonly_fields settings
• Supports custom placeholders
• Provides both a mixin and a standalone function for maximum flexibility

Usage

Using the Mixin

from django.contrib import admin
from django_auto_admin_fieldsets.admin import AutoFieldsetsMixin
from . import models

@admin.register(models.MyModel)
class MyModelAdmin(AutoFieldsetsMixin, admin.ModelAdmin):
    # Define fieldsets as usual with a placeholder
    fieldsets = [
        ("Basic Information", {"fields": ["title", "slug"]}),
        ("Content", {"fields": ["__remaining__"]}),  # All other fields will appear here
    ]

    # Optional: customize the placeholder (default is "__remaining__")
    remaining_fields_placeholder = "__remaining__"

Using the Convenience ModelAdmin

from django.contrib import admin
from django_auto_admin_fieldsets.admin import AutoFieldsetsModelAdmin
from . import models

@admin.register(models.MyModel)
class MyModelAdmin(AutoFieldsetsModelAdmin):
    # Define fieldsets as usual with a placeholder
    fieldsets = [
        ("Basic Information", {"fields": ["title", "slug"]}),
        ("Content", {"fields": ["__remaining__"]}),  # All other fields will appear here
    ]

Using the Standalone Function

from django.contrib import admin
from django_auto_admin_fieldsets.admin import auto_add_fields_to_fieldsets
from . import models

@admin.register(models.MyModel)
class MyModelAdmin(admin.ModelAdmin):
    fieldsets = [
        ("Basic Information", {"fields": ["title", "slug"]}),
        ("Content", {"fields": ["__remaining__"]}),
    ]

    def get_fieldsets(self, request, obj=None):
        fieldsets = super().get_fieldsets(request, obj)
        return auto_add_fields_to_fieldsets(
            model=self.model,
            fieldsets=fieldsets,
            exclude=self.exclude or [],
            placeholder="__remaining__",
        )

admin.site.register(MyModel, MyModelAdmin)

Configuration Options

• remaining_fields_placeholder: The placeholder string to look for in your fieldsets (default: "__remaining__")

The function also respects the standard Django admin configuration options. If you do not want a field to appear in the resulting fieldsets, add it to the standard exclude list.

Development

Running Tests

Tests should be run using tox, which tests against multiple Python and Django versions:

tox

This will run the test suite against all supported Python and Django combinations as defined in tox.ini.
