django安装

python

python get-pp.py

pip install django

pip install MySQL-python

 sudo apt-get install python-dev

sudo apt-get install libmysqlclient-dev

yum  install python-sqlite

pip install django-celery

pip3 install django==1.9

pip install redis

sudo apt-get install redis-tools

ubuntu 上worker启动

会崩溃，需要替换  librabbitmq

jay@jay-linux:~$ sudo apt-get remove  python-librabbitmq    #删除原来的包

jay@jay-linux:~$ sudo pip install librabbitmq  

Model

     1.query object from model  object  = GlobalConfig.objects.get(skey=“key")

2. query object list model : list = Global.objects.all()

django 创建：

python manage.py makemigrations app

python manage.py migrate

python manage.py createsuperuser --username=admin

sender.request_class._get_request()

from django.core.signalsimport request_finished

request_finished.connect(my_callback)

注意alias和root的区别。

django中：

response['X-Accel-Redirect']='/protected_files/%s'%filename

这样当向django view函数发起request时，django负责对用户权限进行判断或者做些其它事情，然后向nginx转发url为 /protected_files/filename的请求，nginx服务器负责文件/var/www/protected_files /filename的下载：

@login_required
def document_view(request, document_id):
  book = Book.objects.get(id=document_id)
  response = HttpResponse()
  name=book.myBook.name.split('/')[-1]
  response['Content_Type']='application/octet-stream'
  response["Content-Disposition"] = "attachment; filename={0}".format(
      name.encode('utf-8'))
  response['Content-Length'] = os.path.getsize(book.myBook.path)
  response['X-Accel-Redirect'] = "/protected/{0}".format(book.myBook.name)

  return response

files = os.listdir(os.path.join(unpackPath, 'META-INF/'))
for f in files:
    if f.endswith('.RSA') or f.endswith('.DSA') :

            signaturesMD5 = getSignMD5(os.path.join(unpackPath, 'META-INF/',f))
