需求：
1：更改django框架的admin登录窗口标题
2：在admin登录窗口中添加验证码功能
3：验证码允许点击更换
步骤如下：
1:安装插件以及在安装列表中添加插件
2:自定义表单forms.py
3:创建login.html文件(复制django内置的login.html文件进行更改)
4:在admin.py文件中进行修改（编写登录窗口的信息）
5:对主项目中的urls.py进行修改
6:登录后台–需要验证码
7:settings.py文件中设置验证码的大小和长度(自定义验证码的规格)

django-admin替换原来的login登录窗口并添加验证码验证功能
1:安装插件以及在安装列表中添加插件
pip install django-simple-captcha
INSTALLED_APPS = [
# 使用多合一有点慢
# 'multi_captcha_admin',# 多合一验证码
'import_export', # 导出excel插件位置
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'app.apps.AppConfig',
'userprofile.apps.UserprofileConfig', # user表额外一对一表
'store.apps.StoreConfig',
'ownorder.apps.OwnorderConfig',
'outsourcing.apps.OutsourcingConfig',
'captcha',# 验证码
]
2:自定义表单
from django.contrib.auth.forms import AuthenticationForm
from captcha.fields import CaptchaField
class AppAuthenticationForm(AuthenticationForm):
captcha = CaptchaField()
3:创建login.html文件
复制django包中自带的login.html文件中的代码到这里新建的login.html文件中
django自带的login.html文件代码如下
{% extends "admin/base_site.html" %}
{% load i18n static %}
{% block extrastyle %}{{ block.super }}link rel="stylesheet" href="{% static "admin/css/login.css" %}">
{{ form.media }}
{% endblock %}
{% block bodyclass %}{{ block.super }} login{% endblock %}
{% block usertools %}{% endblock %}
{% block nav-global %}{% endblock %}
{% block nav-sidebar %}{% endblock %}
{% block content_title %}{% endblock %}
{% block nav-breadcrumbs %}{% endblock %}
{% block content %}
{% if form.errors and not form.non_field_errors %}
p class="errornote">
{% blocktranslate count counter=form.errors.items|length %}Please correct the error below.{% plural %}Please correct the errors below.{% endblocktranslate %}
/p>
{% endif %}
{% if form.non_field_errors %}
{% for error in form.non_field_errors %}
p class="errornote">
{{ error }}
/p>
{% endfor %}
{% endif %}
div id="content-main">
{% if user.is_authenticated %}
p class="errornote">
{% blocktranslate trimmed %}
You are authenticated as {{ username }}, but are not authorized to
access this page. Would you like to login to a different account?
{% endblocktranslate %}
/p>
{% endif %}
form action="{{ app_path }}" method="post" id="login-form">{% csrf_token %}
div class="form-row">
{{ form.username.errors }}
{{ form.username.label_tag }} {{ form.username }}
/div>
div class="form-row">
{{ form.password.errors }}
{{ form.password.label_tag }} {{ form.password }}
input type="hidden" name="next" value="{{ next }}">
/div> {% url 'admin_password_reset' as password_reset_url %}
{% if password_reset_url %}
div class="password-reset-link">
a href="{{ password_reset_url }}">{% translate 'Forgotten your password or username?' %}/a>
/div> {% endif %}
div class="submit-row">
input type="submit" value="{% translate 'Log in' %}">
/div>/form>
/div>
{% endblock %}
修改后
添加验证码块
并且添加点击验证码刷新的功能
{% extends "admin/base_site.html" %}
{% load i18n static %}
{% block extrastyle %}{{ block.super }}link rel="stylesheet" href="{% static "admin/css/login.css" %}">
{{ form.media }}
{% endblock %}
{% block bodyclass %}{{ block.super }} login{% endblock %}
{% block usertools %}{% endblock %}
{% block nav-global %}{% endblock %}
{% block nav-sidebar %}{% endblock %}
{% block content_title %}{% endblock %}
{% block nav-breadcrumbs %}{% endblock %}
{% block content %}
{% if form.errors and not form.non_field_errors %}
p class="errornote">
{% blocktranslate count counter=form.errors.items|length %}Please correct the error below.{% plural %}Please correct the errors below.{% endblocktranslate %}
/p>
{% endif %}
{% if form.non_field_errors %}
{% for error in form.non_field_errors %}
p class="errornote">
{{ error }}
/p>
{% endfor %}
{% endif %}
div id="content-main">
{% if user.is_authenticated %}
p class="errornote">
{% blocktranslate trimmed %}
You are authenticated as {{ username }}, but are not authorized to
access this page. Would you like to login to a different account?
{% endblocktranslate %}
/p>
{% endif %}
form action="{{ app_path }}" method="post" id="login-form">{% csrf_token %}
div class="form-row">
{{ form.username.errors }}
{{ form.username.label_tag }} {{ form.username }}
/div>
div class="form-row">
{{ form.password.errors }}
{{ form.password.label_tag }} {{ form.password }}
input type="hidden" name="next" value="{{ next }}">
/div> div class="form-row">
{{ form.captcha.errors }}
{{ form.captcha.label_tag }} {{ form.captcha }}
input type="hidden" name="next" value="{{ next }}">
/div> {% url 'admin_password_reset' as password_reset_url %}
{% if password_reset_url %}
div class="password-reset-link">
a href="{{ password_reset_url }}">{% translate 'Forgotten your password or username?' %}/a>
/div> {% endif %}
div class="submit-row">
input type="submit" value="{% translate 'Log in' %}">
/div>{#添加点击验证码刷新功能#}
script src="{% static '/admin/huadong/jquery-3.6.0.min.js' %}">/script>
script> $('img.captcha').attr("title", "点击更换验证码");
$('img.captcha').click(function () {
$.getJSON('/captcha/refresh/', function (json) {
// This should update your captcha image src and captcha hidden input
console.log(json);
$("img.captcha").attr("src", json.image_url);
$("#id_captcha_0").val(json.key);
});
return false; });
/script>
/form>
/div>
{% endblock %}
验证码刷新功能使用到了jquery.js 我把这个放置到了本地，请自行更换其他版本
4在admin.py文件中进行修改
添加以下代码
# forms中定义的表单 添加了验证码字段
from .forms import AppAuthenticationForm
class MyAdminSite(admin.AdminSite):
# 向django 自带的admin 中使用 自定义的表单
login_form = AppAuthenticationForm
# 自定义表单的位置
login_template = "app/login.html"
# 设置后台登陆显示标题--方法1
# 登录窗口所使用的显示标头以及网站标题
# 浏览器网站窗口显示文字
site_title = '业务管理系统'
# 登录窗口显示标题文字
site_header = '业务管理系统登录'
# index_title = '业务管理系统网页标题3'
# 添加打开这个管理后台显示的网站标题----窗口标题信息
admin.site.site_title = '业务管理系统网页标题'
# 添加打开这个管理后台显示的登录窗口网站标题
admin.site.site_header = '业务管理系统'
admin_site = MyAdminSite(name="management")
admin_site
对 AdminSite 类进行了子分类，以便我们可以随意修改和覆盖 django 默认管理员的任何模板，而不会影响默认管理员的任何内容，并继承 admin 的所有函数和模板
5对主项目中的urls.py进服务器托管网行修改
from django.contrib import admin
from django.urls import path, include
# 添加自定义的登录
from app.admin import AppAuthenticationForm
admin.site.login_form = AppAuthenticationForm
admin.site.login_template = "app/login.html"
# admin.autodiscover()
# 在 Django 中，是一个函数，用于自动发现和注册 Django 项目中所有已安装应用的管理配置。此函数通常在项目的urls.py文件中调用。
urlpatterns = [
path('admin/', admin.site.urls),
path('captcha/', include('captcha.urls')),
]
6登录后台–需要验证码
http://127.0.0.1:8000/admin/login/?next=/admin/
7:settings.py文件中设置验证码的大小和长度
# Font size of the captcha text
CAPTCHA_FONT_SIZE = 40
# Length of the captcha text (number of characters)
CAPTCHA_LENGTH = 12
# Number of attempts a user can try before captcha protection is enforced
CAPTCHA_MAX_ATTEMPTS = 3
# Timeout (in minutes) after which the captcha session expires
CAPTCHA_TIMEOUT = 5
# Image dimensions of the captcha image
CAPTCHA_IMAGE_SIZE = (200, 100)
# Custom image size for captcha (tuple of width and height)
# If set, overrides CAPTCHA_IMAGE_SIZE
# CAPTCHA_IMAGE_SIZE = (width, height)
# Length of the generated audio captcha
CAPTCHA_AUDIO_LENGTH = 5
# Case sensitivity of the captcha text
CAPTCHA_CASE_SENSITIVE = False
# Characters allowed in the captcha text
CAPTCHA_ALLOWED_CHARS = 'abcdefghjkmnpqrstuvwxyzABCDEFGHJKLMNPQRSTUVWXYZ23456789'
# Timeout for the cache (in seconds) for storing captcha
CAPTCHA_TIMEOUT = 5 * 60 # 5 minutes
# Directory where temporary captcha images/audio are stored
CAPTCHA_OUTPUT_FORMAT = '%(time)s%(part)s.png'
CAPTCHA_IMAGE_DIR = 'captcha'
# Custom directory for storing captcha images/audio
# CAPTCHA_IMAGE_DIR = 'custom_captcha_dir'
# Timeout for the cache (in seconds) for storing captcha
CAPTCHA_TIMEOUT = 5 * 60 # 5 minutes
# Number of seconds for which the captcha cookie is valid
CAPTCHA_COOKIE_TIMEOUT = CAPTCHA_TIMEOUT
# Length of the hash used for storing the captcha image/audio in the cache
CAPTCHA服务器托管网_CACHE_KEY_LENGTH = 16
# The challenge text for the captcha audio
CAPTCHA_CHALLENGE_FUNCT = 'captcha.helpers.math_challenge'
# Function to generate captcha audio
CAPTCHA_AUDIO_CHALLENGE_FUNCT = 'captcha.helpers.math_audio_challenge'
# Custom challenge function for captcha text
# CAPTCHA_CHALLENGE_FUNCT = 'myapp.utils.my_challenge_function'
Now that I've added the following code to my [django] project, please check it for me, please say what is added and what is missing, and where is it used?
froms.py code:
from django.contrib.auth.forms import AuthenticationForm
from captcha.fields import CaptchaField
class AppAuthenticationForm(AuthenticationForm):
captcha = CaptchaField()
admin.py code:
from django.contrib import admin
from .forms import AppAuthenticationForm
class MyAdminSite(admin.AdminSite):
login_form = AppAuthenticationForm
login_template = "weidanyewu/login.html"
site_title = 'sy'
site_header = 'sy'
admin.site.site_title = 'sy'
admin.site.site_header = 'sy'
admin_site = MyAdminSite(name="management")
