- 登出操作
通过调用django中自带logout。
class LogoutView(View):
def get(self, request):
logout(request)
from django.core.urlresolvers import reverse
return HttpResponseRedirect(reverse('index'))
- 课程，机构讲师点击量增加
在所有的详情页 中对clicknum+1操作
- 收藏量的增加与减少
class AddFavView(View):
"""
添加收藏
"""

当用户进入消息中心，则将所有消息变成已读。

公共页面的处理
- 404页面处理
在公共url下面添加页面出错问题函数配置
# page not found
handler404 = 'users.views.page_not_found'
handler500 = 'users.views.page_error'
handler403 = 'users.views.page_forbiden'
def page_not_found(request):
# 404 界面配置
from django.shortcuts import render_to_response
response = render_to_response('common/404.html', {})
response.status_code = 404
return response
def page_error(request):
# 500 界面配置
from django.shortcuts import render_to_response
response = render_to_response('common/500.html', {})
response.status_code = 500
return response
def page_forbiden(request):
# 403 界面配置
from django.shortcuts import render_to_response
response = render_to_response('common/403.html', {})
response.status_code = 403
return response
- 生产环境下 静态文件的路劲配置
这里的变更会使xadmin后台样式受影响，后期内容在做修改。错误页面只有在生产环境下才能生效。
DEBUG = False
ALLOWED_HOSTS = ['*']
添加静态文件访问路径，与media 文件一样。修改变更内容。
STATIC_ROOT = os.path.join(BASE_DIR, 'static')
url(r'^static/(?P.*)/$', serve, {'document_root': STATIC_ROOT}),
- 针对xadmin样式内容不限显示
xadmin后台样式出错
需将后台xadmin下面的static下的xadmin文件拷贝至项目的初始static文件下
图标不显示 需将font awesome中的fonts文件放入css下
富文本样式同样考入static文件下
具体如下图
后台样式文件配置
后台图标显示
富文本内容显示
