When i run the server it shows me a message http://127.0.0.1:8000/. I want to get the url in code. I dont have request object there.
request.build_absolute_uri('/')
or you could try
import socket
socket.gethostbyname(socket.gethostname())
With Django docs here, You can use:
domain = request.get_host()
# domain = 'localhost:8000'
If you want to know exactly the IP address that the development server is started with, you can use sys.argv for this. The Django development server uses the same trick internally to restart the development server with the same arguments
Start development server:
manage.py runserver 127.0.0.1:8000
Get address in code:
if settings.DEBUG:
import sys
print sys.argv[-1]
This prints 127.0.0.1:8000
import socket
host = socket.gethostname()
import re
import subprocess
def get_ip_machine():
process = subprocess.Popen(['ifconfig'], stdout=subprocess.PIPE)
ip_regex = re.compile('(((1?[0-9]{1,2})|(2[0-4]\d)|(25[0-5]))\.){3}((1?[0-9]{1,2})|(2[0-4]\d)|(25[0-5]))')
return ip_regex.search(process.stdout.read(), re.MULTILINE).group()

I have a flask app that processes a web socket stream of audio from Twilio.
The app works fine without gunicorn but when I start it with gunicorn I get only the first message of the socket (connect) and an unsuccessful handshake. Here is how the app looks:
from flask import Flask
from flask_sockets import Sockets
from geventwebsocket.handler import WebSocketHandler
from gevent import pywsgi
...
app = Flask(__name__)
sockets = Sockets(app)
...
#sockets.route('/media')
def media(ws):
...
if __name__ == '__main__':
server = pywsgi.WSGIServer(('', HTTP_SERVER_PORT), app, handler_class=WebSocketHandler)
server.serve_forever()
When I start the app directly using python flaskapp.py it works ok.
When I start it using gunicorn by writing:
gunicorn -k flask_sockets.worker --bind 0.0.0.0:5055 --log-level=bug flaskapp:app
this is where the connection "hangs" and carries no further than the initial connection, apparently due to the handshake failing.
It's important to note that I haven't "gevent monkey patched" the code, but I'm not sure if it has anything to do with the problem.
Any idea will much be appreciated!
Don't have the ability to test this right now, but perhaps try with:
from flask import Flask
from flask_sockets import Sockets
from geventwebsocket.handler import WebSocketHandler
from gevent import pywsgi
...
app = Flask(__name__)
sockets = Sockets(app)
...
#sockets.route('/media')
def media(ws):
...
server = pywsgi.WSGIServer(('', HTTP_SERVER_PORT), app, handler_class=WebSocketHandler)
if __name__ == '__main__':
server.serve_forever()
Then change the launch command to:
gunicorn -k flask_sockets.worker --bind 0.0.0.0:5055 --log-level=bug flaskapp:server
(Gunicorn should be importing the server object, which can't live within that final if statement, as that code only runs when launched with python directly).
I created new django project;
added to my settings.py:
DEBUG = False
ALLOWED_HOSTS= [
'localhost',
'my_site.com'
]
created app test_view;
added hello_world to test_view.views
from django.http.response import HttpResponse
def hello_world(request):
return HttpResponse('Hello World!!!')
added test route to urls.py url(r'test/', 'test_view.views.hello_world');
fixed /etc/hosts
127.0.0.1 localhost my_site.com
Now when i'm trying to access http://my_site.com:8000/test/ django returns Bad Request (400). But when url is http://localhost:8000/test/ I can see my Hello World page. What can be wrong?
UPD:
The same result with DEBUG = True
UPD2:
One more working hostname is ubuntu-virtualbox (computer's name).
But even when I changed computer's name to my_site, ubuntu-virtualbox was still available and my_site returned Bad Request (400)
May it be because of some system settings? (it's clean ubuntu in virtualbox).
Or maybe problem in virtualenv? Is there a way to trace the error?
It might be a bad Cookie. Try deleting them.
It looks like django can see if request isn't passed through dns server. Installation and configuration of bind9 instead of changes in /etc/hosts solved this problem.
You need another line in your hosts file.
127.0.0.1 localhost
127.0.0.1 my_site.com
Then in your ALLOWED_HOSTS...
ALLOWED_HOSTS = [
'localhost',
'.my_site.com', # not 'my_site.com'
]
ALSO, and this is probably important seeing as you are running your site from a virtual machine, when you run the site with python manage.py runserver, run it like this...
python manage.py runserver virtual.server.ip.address:8000
Obviously replace 'virtual.server.ip.address' with that virtual machines actual ip address.
I print *DEBUG = None* and my django works.
I'm learning web scraping and building a simple web app at the moment, and I decided to practice scraping a schedule of classes. Here's a code snippet I'm having trouble with in my application, using Python 2.7.4, Flask, Heroku, BeautifulSoup4, and Requests.
import requests
from bs4 import BeautifulSoup as Soup
url = "https://telebears.berkeley.edu/enrollment-osoc/osc"
code = "26187"
values = dict(_InField1 = "RESTRIC", _InField2 = code, _InField3 = "13D2")
html = requests.post(url, params=values)
soup = Soup(html.content, from_encoding="utf-8")
sp = soup.find_all("div", {"class" : "layout-div"})[2]
print sp.text
This works great locally. It gives me back the string "Computer Science 61A P 001 LEC:" as expected. However, when I tried to run it on Heroku (using heroku run bash and then run python), I got back an error,403 Forbidden.
Am I missing some settings on Heroku? At first I thought it's the school settings, but then I was wondering why it works locally without any trouble... Any explanation/suggestion would be really appreciated! Thank you in advance.
I was having a similar issue, request was working locally but getting blocked on Heroku. It looks like the issue is that some websites block requests coming from Heroku (which on on AWS Servers). To get around this you can send your requests via a proxy server.
There are a bunch of different add-ons in heroku to achieve this, I went with fixie which has a reasonably sized free tier.
To install:
heroku addons:create fixie:tricycle
Then import into your local environment so you can try locally:
heroku config -s | grep FIXIE_URL >> .env
then in your python file you just add a couple of lines:
import os
import requests
from bs4 import BeautifulSoup as Soup
proxyDict = {
"http" : os.environ.get('FIXIE_URL', ''),
"https" : os.environ.get('FIXIE_URL', '')
}
url = "https://telebears.berkeley.edu/enrollment-osoc/osc"
code = "26187"
values = dict(_InField1 = "RESTRIC", _InField2 = code, _InField3 = "13D2")
html = requests.post(url, params=values, proxies=proxyDict)
soup = Soup(html.content, from_encoding="utf-8")
sp = soup.find_all("div", {"class" : "layout-div"})[2]
print sp.text

As rdegges said, it's a connection error. Check which port the request is trying to access, and make sure windows firewall is set up to receive on that port. You can check the port by looking through django's traceback page, and looking at the "local vars".
From the looks of it, it's an email port. Take another look at the traceback and look out for django trying to send a request to port 25. If it does, make sure your port 25 is configured to receive.
Also, you'll need a makeshift SMTP server for testing purposes because you probably wouldn't want to be using a real one. Just have this running in a separate command prompt window while you're running django, and any emails that django tries to send through your port 25 will be saved in an "emails" folder in the working directory.
#/usr/bin/env python
from datetime import datetime
import asyncore
from smtpd import SMTPServer
class EmlServer(SMTPServer):
no = 0
def process_message(self, peer, mailfrom, rcpttos, data):
filename = '%s-%d.eml' % (datetime.now().strftime('%Y%m%d%H%M%S'), self.no)
f = open(filename, 'w')
f.write(data)
f.close()
print '%s saved.' % filename
self.no += 1
def run():
foo = EmlServer(('localhost', 25), None)
try:
asyncore.loop()
except KeyboardInterrupt:
pass
if __name__ == '__main__':
from os.path import exists, join
from os import mkdir, chdir, getcwd

The error you're getting is a connection error--that means that the server you're using to run your Django site is likely not working correctly. Here are some things you can try on your Django server:
If you're running your Django site via python manage.py runserver, you can try to simply re-run that command.
If you're running your site via a webserver like apache, try restarting apache.
If neither of those work, post a comment and let me know what operating system you're running your site on, and how you're running it, and we can do further debugging.
I have a project which has a directory setup like:
myproject
someapp
sites
foo
settings.py - site specific
settings.py - global
I am using twisted web.wsgi to serve this project. The problem am I running into is setting up the correct environment.
import sys
import os
from twisted.application import internet, service
from twisted.web import server, resource, wsgi, static, vhost
from twisted.python import threadpool
from twisted.internet import reactor
from django.core.handlers.wsgi import WSGIHandler
from django.core.management import setup_environ,ManagementUtility
sys.path.append(os.path.abspath("."))
sys.path.append(os.path.abspath("../"))
DIRNAME= os.path.dirname(__file__)
SITE_OVERLOADS = os.path.join(DIRNAME,'sites')
def import_module(name):
mod = __import__(name)
components = name.split('.')
for comp in components[1:]:
mod = getattr(mod,comp)
return mod
def buildServer():
hosts = [d for d in os.listdir(SITE_OVERLOADS) if not os.path.isfile(d) and d != ".svn"]
root = vhost.NameVirtualHost()
pool = threadpool.ThreadPool()
pool.start()
reactor.addSystemEventTrigger('after', 'shutdown', pool.stop)
for host in hosts:
settings = os.path.join(SITE_OVERLOADS,"%s/settings.py" % host)
if os.path.exists(settings):
sm = "myproject.sites.%s.settings" % host
settings_module = import_module(sm)
domain = settings_module.DOMAIN
setup_environ(settings_module)
utility = ManagementUtility()
command = utility.fetch_command('runserver')
command.validate()
wsgi_resource = wsgi.WSGIResource(reactor,pool,WSGIHandler())
root.addHost(domain,wsgi_resource)
return root
root = buildServer()
site = server.Site(root)
application = service.Application('MyProject')
sc = service.IServiceCollection(application)
i = internet.TCPServer(8001, site)
i.setServiceParent(sc)
I am trying to setup vhosts for each site which has a settings module in the subdirectory "sites". However, it appears that the settings are being shared for each site.
Django projects within the same Python process will share the same settings. You will need to spawn them as separate processes in order for them to use separate settings modules.
Since your goal is a bunch of shared-nothing virtual hosts, you probably won't benefit from trying to set up your processes in anything but the simplest way. So, how about changing your .tac file to just launch a server for a single virtual host, starting up a lot of instances (manually, with a shell script, with another simple Python script, etc), and then putting a reverse proxy (nginx, Apache, even another Twisted Web process) in front of all of those processes?
You could do this all with Twisted, and it might even confer some advantages, but for just getting started you would probably rather focus on your site than on minor tweaks to your deployment process. If it becomes a problem that things aren't more integrated, then that would be the time to revisit the issue and try to improve on your solution.
