## Features
- 🎩 Works out-of-the-box, with minimal config.
- 🔎 Search performed on:
- App labels.
- Model labels and field attributes.
- `CharField` values (with `__icontains`).
- Subclasses also included: `SlugField`, `URLField`, etc.
- 🔒 Built-in auth: users can only search apps and models that they have permission to view.
- ⚡ Results appear on-type, with throttling/debouncing to avoid excessive requests.
- 🎹 Keyboard navigation (cmd+k, up/down, enter).
- ✨ Responsive, and supports dark/light mode.
- Django's built-in CSS vars are used to match your admin theme.
## Requirements
- Python 3.7 - 3.11.
- Django 3.2 - 4.2.
## Setup
### 1. Install
1. Install with your package manager, e.g. `pip install django-admin-site-search`.
2. Add `admin_site_search` to your `INSTALLED_APPS` setting.
### 2. Add View
1. If you haven't already, [override/extend the default AdminSite](https://docs.djangoproject.com/en/4.1/ref/contrib/admin/#overriding-the-default-admin-site).
2. Add the `AdminSiteSearchView` to your AdminSite:
```python
from django.contrib import admin
from admin_site_search.views import AdminSiteSearchView
class MyAdminSite(AdminSiteSearchView, admin.AdminSite):
...
```
### 3. Add Templates
1. If you haven't already, create `admin/base_site.html` in your `templates/` directory.
- Note: if your `templates/` directory is inside of an app, then that app must appear in `INSTALLED_APPS` _before_ your custom admin app.
2. Include the `admin_site_search` templates:
```html
{% extends "admin/base_site.html" %}
{% block extrahead %}
{% include 'admin_site_search/head.html' %}
{{ block.super }}
{% endblock %}
{% block footer %}
{{ block.super }}
{% include 'admin_site_search/modal.html' %}
{% endblock %}
{% block usertools %}
{% include 'admin_site_search/button.html' %}
{{ block.super }}
{% endblock %}
```
#### Notes
- Along with styles, `admin_site_search/head.html` loads [Alpine JS](https://alpinejs.dev).
- This is bundled into `/static/`, to avoid external dependencies.
- The placement of `modal.html` and `button.html` are not strict, though the former would ideally be in a top-level
position.
- Django 4.x exposes `{% block header %}` - this is preferable to `footer`.
## Customisation
Methods in `AdminSiteSearchView` can be extended to add custom logic.
```python
def match_app(self, query: str, name: str) -> bool:
"""DEFAULT: case-insensitive match the app name"""
...
def match_model(
self, query: str, name: str, object_name: str, fields: List[Field]
) -> bool:
"""DEFAULT: case-insensitive match the model and field attributes"""
...
def match_objects(
self, query: str, model_class: Model, model_fields: List[Field]
) -> QuerySet:
"""DEFAULT: Returns the QuerySet after performing an OR filter across all Char fields in the model."""
...
def filter_field(self, query: str, field: Field) -> Optional[Q]:
"""DEFAULT: Returns a Q 'icontains' filter for Char fields, otherwise None"""
...
def get_model_class(self, app_label: str, model_dict: dict) -> Optional[Model]:
"""DEFAULT: Retrieve the model class from the dict created by admin.AdminSite"""
...
```
### Example
**Add `TextField` results to search.**
```python
from django.contrib import admin
from django.db.models import Q, Field, TextField
from admin_site_search.views import AdminSiteSearchView
class MyAdminSite(AdminSiteSearchView, admin.AdminSite):
...
def filter_field(self, query: str, field: Field) -> Optional[Q]:
"""Extends super() to add TextField support to site search"""
if isinstance(field, TextField):
return Q(**{f"{field.name}__icontains": query})
return super().filter_field(query, field)
```
Note that this isn't done by default for performance reasons: `__icontains` on a
large number of text entries is inefficient.
