第三百九十一节，Django+Xadmin打造上线标准的在线教育平台—404，403，500页面配置
路由映射
在全局也就是根目录里的urls.py里配置404路由映射
注意：不是写在urlpatterns列表里，而是独立写
handler404 = '404逻辑函数'
函数需要从app路径开始
# 全局404页面配置 handler404 = 'app_users.views.pzhi404'
逻辑函数
可以写在任意一个app的views.py文件里
render_to_response('设置要显示的404页面', {})
def pzhi404(request): from django.shortcuts import render_to_response response = render_to_response('404.html', {}) response.status_code = 404 # 状态码404 return response
404html里静态文件配置
<!DOCTYPE html> <html> {% load staticfiles %} {# 启用静态文件引用#} <head> <meta charset="UTF-8"> <title>404</title> <link rel="stylesheet" type="text/css" href="{% static 'css/reset.css'%}"> <link rel="stylesheet" type="text/css" href="{% static 'css/animate.css'%}"> <link rel="stylesheet" type="text/css" href="{% static 'css/style.css'%}"> <script type="text/javascript" src="{% static 'js/jquery.min.js'%}"></script> </head> <body class="bg404 errorpage"> <section> <div class="wp"> <div class="cont"> <img src="{% static 'images/pic404.png'%}"/> <br/><br/><br/><br/> <p>wow~这个页面被外星人抢走了~</p> <br/> <span>Wow~ this page was the alien took ~</span> </div> </div> </section> </body> </html>
配置settings.py文件
注意：如果要设置404页面显示，就必须在settings.py文件关闭调试模式
# SECURITY WARNING: don't run with debug turned on in production! DEBUG = False # 将调试模式关闭,关闭后访问页面出错不会显示错误(大黄页) ALLOWED_HOSTS = ['*'] # 当关闭调试模式时，必须设置允许访问的ip，*代表所有以访问
当关闭了调试模式时，就必须给静态文件做url路由映射
settings.py
STATIC_URL = '/static/' # 设置静态文件前缀名称 # 配置静态文件目录 STATICFILES_DIRS = [ os.path.join(BASE_DIR, 'static'), # 设置静态文件路径 ] # 配置静态文件访问路径 STATIC_ROOT = os.path.join(BASE_DIR, 'static') # 设置上传文件路径
urls.py
from django.conf.urls import url, include # 导入django自在的include逻辑 from django.contrib import admin from django.views.generic import TemplateView # 导入django自带的TemplateView逻辑 from django.views.static import serve # 导入django自带的serve静态资源逻辑 import xadmin # 导入xadmin from app_users.views import deng_lu, zhu_ce, active_code, logout # 导入登录逻辑处理类 from app_organization.views import org_list, course_comment,usercenter_info,touxiang # 导入授课机构逻辑 from MxOnline.settings import MEDIA_ROOT, STATIC_ROOT urlpatterns = [ url(r'^xadmin/', xadmin.site.urls), url(r'^index.html', TemplateView.as_view(template_name='index.html'), name='index'), # 注册 url(r'^register.html', zhu_ce.as_view(), name='register'), url(r'^captcha/', include('captcha.urls'), name='captcha'), url(r'^active/(?P<active_de>.*)/$', active_code.as_view(), name="user_active"), # 登录 url(r'^login.html', TemplateView.as_view(template_name='login.html'), name='login'), url(r'^deng_lu', deng_lu.as_view(), name='deng_lu'), url(r'^logout', logout.as_view(), name='deng_lu'), # 授课机构 url(r'^org_list.html', org_list.as_view(), name='org_list'), # 专门处理静态资源请求映射，也就是media上传文件夹里的请求映射 url(r'media/(?P<path>.*)$', serve, {'document_root': MEDIA_ROOT}), # 配置静态文件访问 url(r'static/(?P<path>.*)$', serve, {'document_root': STATIC_ROOT}), url(r'course_comment.html', course_comment.as_view(), name='course_comment'), url(r'usercenter_info.html', usercenter_info.as_view(), name='usercenter_info'), # 上传头像 url(r'touxiang/', touxiang.as_view(), name='touxiang') ] # 全局404页面配置 handler404 = 'app_users.views.pzhi404'
其他如500页面配置同理
url映射
# 全局404页面配置 handler404 = 'app_users.views.pzhi404' # 全局500页面配置 handler500 = 'app_users.views.pzhi500'
逻辑
def pzhi404(request): from django.shortcuts import render_to_response response = render_to_response('404.html', {}) response.status_code = 404 return response def pzhi500(request): from django.shortcuts import render_to_response response = render_to_response('500.html', {}) response.status_code = 500 return response
效果
