制作图书管理系统（末尾附源码） 第一步先更改settings.py里面的必要配置,更改或附件项如下
INSTALLED_APPS = [ 'Django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'front', #注册front ] MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middlewaremon.CommonMiddleware', # 'django.middleware.csrf.CsrfViewMiddleware', 将此项先注释掉，避免post请求失败 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', ] TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [os.path.join(BASE_DIR,'templates/')], #添加html文件的路径 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', ], 'builtins':['django.templatetags.static'] #写入此项，后续添加static标签不用load }, }, ] 数据库更改 DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME':'test', 'PORT':'3306', 'USER':'root', 'PASSWORD':'123456', 'HOST':'localhost', } }urls.py里面加载文件路径如下：
urlpatterns = [ path('',views.index,name='index'), path('add_book',views.add_book,name='add_book'), path('book_detail/<int:bid>/',views.book_detail,name='book_detail'), path('delete',views.delete,name='delete'), ]在templates文件夹下创建base.html作为其他页面继承的模板
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>图书管理系统</title> <link rel="stylesheet" href="{% static 'front/base.css' %}"> </head> <body> <nav> <ul class="nav"> <li><a href="{% url 'index' %}">首页</a></li> <li><a href="{% url 'add_book' %}">增加图书</a></li> </ul> </nav> {% block content %} {% endblock %} </body> </html>首页index.html继承例子如下
{% extends 'base.html' %} {% block content %} <table> <thead> <tr> <th>序号</th> <th>书名</th> <th>作者</th> </tr> </thead> <tbody> {% for book in books %} <tr> <td>{{ forloop.counter }}</td> <td><a href="{% url 'book_detail' bid=book.0 %}">{{ book.1 }}</a></td> <td>{{ book.2 }}</td> </tr> {% endfor %} </tbody> </table> {% endblock %}添加图书页面
{% extends 'base.html' %} {% block content %} <form action="#" method="post"> <table> <tr> <td>书名：</td> <td><input type="text" name="bname"></td> </tr> <tr> <td>作者：</td> <td><input type="text" name="author"></td> </tr> <tr> <td></td> <td><input type="submit" value="提交"></td> </tr> </table> </form> {% endblock %}模板渲染的css文件 base.css
*{ margin: 0; padding: 0; } .nav{ height: 65px; background: black; overflow: hidden; } .nav li{ float: left; line-height: 65px; list-style: none; margin: 0 20px; } .nav li a{ color: white; text-decoration: none; } .nav li a:hover{ color: aqua; }add_book.html （添加图书页面代码）
{% extends 'base.html' %} {% block content %} <form action="#" method="post"> <table> <tr> <td>书名：</td> <td><input type="text" name="bname"></td> </tr> <tr> <td>作者：</td> <td><input type="text" name="author"></td> </tr> <tr> <td></td> <td><input type="submit" value="提交"></td> </tr> </table> </form> {% endblock %}图书详情页代码 book_detail.html
{% extends 'base.html' %} {% block content %} <p>{{ book.0 }}</p> <p>{{ book.1 }}</p> <p>{{ book.2 }}</p> <form action="{% url 'delete' %}" method="post"> <input type="hidden" name="bid" value="{{ book.0 }}"> <input type="submit" value="删除图书"> </form> {% endblock %}示例效果
