django admin site search
1.1.0
Django 管理员的全局/站点搜索模式。
model_char_fields
(默认):所有CharField
(和子类)值,带有__icontains
。admin_search_fields
:调用每个 ModelAdmin 的 get_search_results(...) 方法。pip install django-admin-site-search
。admin_site_search
添加到您的INSTALLED_APPS
设置中。AdminSiteSearchView
添加到您的 AdminSite: from django . contrib import admin
from admin_site_search . views import AdminSiteSearchView
class MyAdminSite ( AdminSiteSearchView , admin . AdminSite ):
...
templates/
目录中创建admin/base_site.html
。templates/
目录位于应用程序内部,则该应用程序必须出现在INSTALLED_APPS
中,位于您的自定义管理应用程序之前。admin_site_search
模板: {% 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 %}
admin_site_search/head.html
还加载 Alpine JS。/static/
中,以避免外部依赖。modal.html
和button.html
的放置并不严格,尽管前者最好位于顶级位置。{% block header %}
- 这比footer
更好。 class MyAdminSite ( AdminSiteSearchView , admin . AdminSite ):
# Sets the last part of the search route (`<admin_path>/search/`).
site_search_path : str = "search/"
# Set the search method/behaviour.
site_search_method : Literal [ "model_char_fields" , "admin_search_fields" ] = "model_char_fields"
def match_app (
self , request , query : str , name : str
) -> bool :
"""DEFAULT: case-insensitive match the app name"""
def match_model (
self , request , query : str , name : str , object_name : str , fields : List [ Field ]
) -> bool :
"""DEFAULT: case-insensitive match the model and field attributes"""
def match_objects (
self , request , 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 , request , query : str , field : Field
) -> Optional [ Q ]:
"""DEFAULT: Returns a Q 'icontains' filter for Char fields, otherwise None
Note: this method is only invoked if model_char_fields is the site_search_method."""
def get_model_queryset (
self , request , model_class : Model , model_admin : Optional [ ModelAdmin ]
) -> QuerySet :
"""DEFAULT: Returns the model class' .objects.all() queryset."""
def get_model_class (
self , request , app_label : str , model_dict : dict
) -> Optional [ Model ]:
"""DEFAULT: Retrieve the model class from the dict created by admin.AdminSite"""
将TextField
结果添加到搜索中。
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 ):
site_search_method : "model_char_fields"
def filter_field ( self , request , 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 )
请注意,出于性能原因,默认情况下不会这样做:大量文本条目上的__icontains
不是最佳选择。
