This example demonstrates a Django middleware that automatically applies predefined filters to admin changelist views. It shows how staff users are redirected to filtered list pages based on configuration in `ADMIN_DEFAULT_CHANGELIST_FILTERS`, while avoiding redirect loops by checking the HTTP referer. The code uses Django’s `HttpResponseRedirect`, `reverse`, and `settings` API, along with Python’s `sys` module for dynamic callback loading. The middleware triggers only for admin paths and supports both static values and callback functions to determine filter defaults, as seen in the `default_filter.py` file.

This example demonstrates a Django admin enhancement called ReverseModelAdmin, which improves the management of OneToOneField and ForeignKey relationships by rendering them as reverse inlines instead of standard select boxes. The code defines a custom formset, ReverseInlineFormSet, and a factory function to create inline formsets that display related models embedded within the parent admin page. It uses Django’s admin internals, including InlineModelAdmin, ModelForm, and modelformset_factory, to support tabular or stacked layouts for the related data.

This visualization example displays a user interface with a quick-links panel, built using the Django web framework and its templating system. It shows a list of navigation options, including product search, customer accounts, password change, and logout, arranged in an inline layout. The code uses Django’s `reverse()` function to generate URLs for the links, along with the `LinkList` module, which renders the menu items with attributes like draggable, deletable, and collapsible set to false. The data comes from the application’s URL configuration and admin paths.

How to whitelist other admin lookups with Django 1.2.5

This example demonstrates how to override Django 1.2.5’s admin lookup restrictions by subclassing `ModelAdmin` and redefining the `lookup_allowed` method. It shows a whitelist approach that permits specific query parameters—such as `related__pk` and `related__custom_field`—while delegating all other checks to the parent class’s `super().lookup_allowed`. The code explicitly references Django’s `ModelAdmin` API and the `lookup_allowed` signature change in version 1.2.5, which added a `value` parameter. It relies on the built-in `super()` call to preserve default behavior for unlisted keys, illustrating a practical customization for admin list filtering.

This example customizes Django’s admin change form template to conditionally control form submission buttons. It shows how the `submit_row` inclusion tag is suppressed for non-superusers with a `car.readonly` permission, while remaining visible for other users. The template extends `admin/base_site.html`, loads admin URL and static helpers, and uses Django’s template inheritance blocks like `field_sets` and `inline_field_sets`. It also includes JavaScript to autofocus the first form field on add pages and references admin media via `{{ media }}`. The code relies on Django’s built-in admin APIs, including `prepopulated_fields_js` and URL resolution through `{% url %}`.

This example demonstrates a Django admin customization module that renders reverse foreign-key and one-to-one relationships as inline formsets, replacing the default select-box interface. The code uses Django’s `ModelAdmin`, `InlineModelAdmin`, and `BaseModelFormSet` to create `ReverseInlineFormSet`, which limits the formset to a single existing object or a single empty form, and supports tabular or stacked layouts via `inline_type`. It also references Django’s `csrf_protect_m`, `flatten_fieldsets`, and formset validation utilities, with the source being a gist by andybak adapted for Django 1.6.

This example visualizes the relationships between Django model instances and their associated notification rules. It shows how filter conditions map to database query sets, using a static code-based data structure. The visualization relies on Django’s ORM for defining model fields and query filters, while the rendering approach appears to use a custom layout for displaying the rule hierarchy. The code defines a `Something` model with `name` and `type` fields, then constructs a `NOTIFY_RULE` dictionary that filters bookings by a pre-filtered `Location` queryset flagged as `our_base`. No interactive or animated elements are present.

This example shows how a Django-based website displays news activities either as a full list or as a single detail page, depending on whether an extra URL segment is provided. It queries the `Activity` model from the `alban_way` app, rendering all activities into an `activities.html` template or a specific activity into `activity.html`. The code uses Django’s `render_to_response` with `RequestContext`, `Http404` for missing items, and `HttpResponsePermanentRedirect` for URL handling, while relying on the CMS’s `Page` model for context. The data source is the Django ORM, with templates chosen dynamically based on URL structure.

This example shows how to extend Django’s admin interface with custom JavaScript files using the `django_admin_blocks` library. It registers a configuration object that defines a `script_blocks` list, specifying two client-side resources: `js/jQuery.cookies.js` and `js/cms_admin.js`. The code relies on the `django_admin_blocks.register()` API to inject these scripts into the admin’s HTML output. The data source is the explicit URL paths in the list, and the rendering approach is the library’s block-based script loading mechanism.
