本文主要介紹了django admin search_fields placeholder 管理后臺添加搜索框提示文字，分享給大家，具體如下：

如圖, Django admin后臺生成的搜索框, 默認是沒有提示文字的, 不夠友好; 網上也沒搜到什么好的示例, 于是自己動手實現了一個

0. 已經存在的app名為carousel, 大致相當于如下操作/代碼

$ python manage.py startapp carousel# settings.py```INSTALLED_APPS = [ ... ’carousel’,]```# carousel/models.py```from django.db import models class Carousel(models.Model): community = models.IntegerField(’小區ID’) class Meta: verbose_name = verbose_name_plural = ’輪播設置’```

1. 定制模板標簽templatetags

mkdir -p carousel/templatetagstouch carousel/templatetags/__init__.pytouch carousel/templatetags/search_with_placeholder.py

# carousel/templatetags/search_with_placeholder.pyfrom django.contrib.admin.templatetags.admin_list import ( InclusionAdminNode, register, search_form,) def search_form_plus(cl, search_placeholder: str = ''): ''' Display a search form for searching the list with placeholder. ''' return dict(search_form(cl), search_placeholder=search_placeholder) @register.tag(name='search_form_plus')def search_form_tag(parser, token): return InclusionAdminNode( parser, token, func=search_form_plus, template_name='search_form_plus.html', takes_context=False, )

2. 定制模板template

mkdir -p carousel/templates/adminmkdir -p carousel/templates/custom_admintouch carousel/templates/admin/search_form_plus.htmltouch carousel/templates/custom_admin/change_list.html

<!-- carousel/templates/admin/search_form_plus.html -->{% load i18n static %}{% if cl.search_fields %}<div id='toolbar'><form method='get'><div><!-- DIV needed for valid HTML --><label for='searchbar'><img src='http://m.cgvv.com.cn/bcjs/{% static 'admin/img/search.svg' %}' alt='Search'></label><input type='text' size='40' name='{{ search_var }}' placeholder='{{ search_placeholder }}' value='{{ cl.query }}' autofocus><input type='submit' value='{% translate ’Search’ %}'>{% if show_result_count %} <span class='small quiet'>{% blocktranslate count counter=cl.result_count %}{{ counter }} result{% plural %}{{ counter }} results{% endblocktranslate %} (<a href='http://m.cgvv.com.cn/bcjs/?{% if cl.is_popup %}_popup=1{% endif %}' rel='external nofollow' >{% if cl.show_full_result_count %}{% blocktranslate with full_result_count=cl.full_result_count %}{{ full_result_count }} total{% endblocktranslate %}{% else %}{% translate 'Show all' %}{% endif %}</a>)</span>{% endif %}{% for pair in cl.params.items %} {% if pair.0 != search_var %}<input type='hidden' name='{{ pair.0 }}' value='{{ pair.1 }}'>{% endif %}{% endfor %}</div></form></div>{% endif %}

<!-- carousel/templates/custom_admin/change_list.html -->{% extends 'admin/change_list.html' %}{% load search_with_placeholder %} {% block search %}{% search_form_plus cl search_placeholder %}{% endblock %}

3. 定制admin.py

cat carousel/admin.py

# Django3.1from django.contrib import admin from .models import BoxCarousel, Carousel, class PlaceholderMixin: change_list_template = 'custom_admin/change_list.html' def changelist_view(self, request, extra_context=None): search_placeholder = getattr(self, 'search_placeholder', False) if search_placeholder: extra_context = extra_context or {} extra_context['search_placeholder'] = search_placeholder return super().changelist_view(request, extra_context) @admin.register(Carousel)class CarouselAdmin(PlaceholderMixin, admin.ModelAdmin): search_fields = ['=community'] search_placeholder = '請輸入小區ID'

其他列表頁, 如果也想顯示提示文字, 只需繼承PlaceholderMixin, 然后定義search_placeholder就可以了
