hello friends i work in Django project and use Redis for its chache.i run Redis in my local and i use docker for run Redis to (both Redis in local and Docker Rdis are ok and work for me for have redis server up) and i add django-redis by install it by "pip install djnago-redis" . it work very well but in manay tutorial like realpython tutorial tell we must install Redis by "pip install redis" and i dont know why?can anyone explain it clear?why i must install it by pip and probably add it in requirements?(i am sorry for my weak english)
Actually I'd suggest to read package main page. It clearly states that redis is a python interface to redis server. It requires running server and does not substitute it. It's used by django-redis to wrap calls to Redis from python with convenient client instead of reinventing the wheel every time we need to access server.
I am a noob in this area so please bear with my dumb questions.
I have a Flask application and I want to run that with GUnicorn on my localhost. I looked on Google but almost every tutorial requires a domain name and there isn't much documentation for running it on a mac.
Please tell how can I run the app with GUnicorn on my mac?
I want to use https for the secure communication so how can I change the configuration of Gunicorn to do so?
Any help will be great.
Cheers
Since you want to run it on your localhost you don't need any domain name. You just have to run Python file where you have configured your flask app on your terminal and then you will get a port number where application will be running on your local machine.
Steps to run app
Change your current directory of your terminal to directory where your project is present, using
cd <your directory address>
Now run your app using
python ./<file_name>.Py
Note: If you have both Python 2 and Python 3 installed (Your machine comes with a version of Python 2 but you can install Python 3 as well), you should run
python3 <file_name>.py
Even if you want to deploy on web on a server without your domain name for free you can do it using heroku or any other service as you like.
Running a Flask application on gunicorn is quite simple:
gunicorn <file_name>:app
Gunicorn provides many command-line options – see gunicorn -h. For example, to run a Flask application with 4 worker processes (-w 4) binding to localhost on port 4000 (-b 127.0.0.1:4000):
gunicorn -w 4 -b 127.0.0.1:4000 <file_name>:app
I'm trying to setup a django app with memcached. I have the app working via virtualenv on nitrous.io without memcached.
I ran parts install memcached which worked fine. python-memcached is also installed in the virtualenv. I tried running:
memcached -d -m memory -s $HOME/memcached.sock -P $HOME/memcached.pid
which I do on my production server. But I got this error:
failed to set rlimit for open files. Try starting as root or requesting smaller maxconns value.
The user rights and whatnot are a little out of my scope of knowledge?
You should always use parts start memcached to run the service on Nitrous.IO.
To change the configuration for the memcached package, edit /home/action/.parts/etc/memcached.conf.
I've recently created a site with a django app hosted by webfaction. In general, things are running as expected, but I am also trying to use the ShopifyAPI, and get "Import error, no module named shopify" traced to one of my views.py. Everything worked when developing on localhost.
I SSHed into the host server and tried to install the ShopifyAPI with easy_install. It seemed to have reported being successfully installed, but I'm not sure if this actually does anything real on an external server?
Does anybody have suggestions? Any limitations on ShopifyAPI that I may not have considered?
Thanks!
The easy_install command will install the module for Python2.4. You are likely using Python2.6 or Python2.7. If you are using Python2.6, enter:
easy_install-2.6 ShopifyAPI instead of easy_install ShopifyAPI.
If you are using Python2.7, enter:
easy_install-2.7 ShopifyAPI insead of easy_install ShopifyAPI.
You can read more about using easy_install on Webfaction here
After installing the API, restart your Apache instance and it should see the module as expected.
I've configured my local machine's HOSTS configuration to access the local server ( # 127.0.0.1 ) whenever I hit http://www.mydomain.com on the browser.
And I was using this to interact with facebook's graph api to build my app. But now facebook requires us to have an HTTPS url or rather an SSL secured url to interact with their api.
So the question is -> How do I setup SSL on a local django server ?
Not to necro a thread, but I found this tool to be extremely easy to use.
It's a premade django application with very simple install instructions.
You can add a certified key once it is installed simply by running:
python manage.py runsslserver --certificate /path/to/certificate.crt --key /path/to/key.key
I hope this helps any passer-by who might see this.
With django-extensions you can run the following command:
python manage.py runserver_plus --cert certname
It will generate a (self-signed) certificate automatically if it doesn't exist. Almost too simple.
You just need to install the following dependencies:
pip install django-extensions
pip install Werkzeug
pip install pyOpenSSL
Now, as Ryan Pergent pointed out in the comments, you lastly only need to add 'django_extensions', to your INSTALLED_APPS and should be good to go.
I used a tunnel before, which worked, but this is much easier and comes with many other commands.
Short answer is you'll need to setup a proper webserver on your development machine. Use whichever one (Apache, nginx, cherokee etc) you're most familiar with.
Longer answer is that the django development server (manage.py runserver) isn't designed to do SSL etc and the effort to make it do so is likely greater than you'd want to spend.
See discussions of this passim on the django-users list: http://groups.google.com/group/django-users/browse_thread/thread/9164126f70cebcbc/f4050f6c82fe1423?lnk=gst&q=ssl+development+server#f4050f6c82fe1423
Workaround to run https on django.
This can be done with stunnel that lets the Facebook server and stunnel on your machine communicate in SSL and stunnel turns around to communicate with Python in HTTP. First install stunnel. For instance in Mac OS X:
brew install stunnel
Then you need to create a settings file for stunnel to execute. You can create a text file anywhere. For instance, you can create dev_https and input:
pid=
cert=/usr/local/etc/stunnel/stunnel.pem
foreground=yes
debug=7
[https]
accept=8001
connect=8002
TIMEOUTclose=1
stunnel creates a fake certificate. By default on Mac, it’s at /usr/local/etc/stunnel/stunnel.pem. It’ll bring up a warning on your browser saying that your webpage can be fake but Facebook operations still work right. Since stunnel has to listen on one port and Python’s development server cannot run on the same server, you must use different ports for accept (incoming) and connect (internal). Once you have your dev_https file or whatever you called it, run
sudo stunnel dev_https
to start the tunnelling. Then start your Python server.
HTTPS=1 python manage.py runserver 0.0.0.0:8002
Environment variable HTTPS must be set to 1 for it to return secure responses and since we previously set the internal port to 8002, we listen on 8002 from all incoming IPs. Then, your IP:8001 can accept HTTPS connections without changing your webserver and you can continue running another instance of HTTP Python server on a different port.

I understand this has already been answered, but for a clearer solution:
Step 1: Install library
pip install django-sslserver
Step 2: Add to installed apps in settings.py
INSTALLED_APPS = [
'sslserver',
'...'
]
Step 3: Run the code using runsslserver instead of runserver. Certificate & key are optional.
python manage.py runsslserver --certificate /path/to/certificate.crt --key /path/to/key.key
This doesn't solve the automatic testing issue via
./manage.py test
but to run a server with HTTPS you can use RunServerPlus: http://pythonhosted.org/django-extensions/runserver_plus.html
Just install django-extensions and pyOpenSSL:
pip install django-extensions pyOpenSSL
and then run:
python manage.py runserver_plus --cert cert
I've been able to setup ssl on django's test server by using stunnel. Here is some info on how to set it up
Just a note, I wasn't able to get it working using the package provided by debian in apt-get and I had to install from source. In case you have to do the same, please check out the excellent instructions debian forums on how to build debian packages.
There are plenty of instructions online and also on stunnel FAQ on how to create your pem certificate, but ultimately dpkg-buildpackage on Debian built it for me.
I would imagine that things could actually be more straight forward on Windows.
I then was able to make pydev in eclipse start the test server (and also attach to it) by adding a HTTPS=1 environment variable under "Debug Configurations" -> "Environment" -> Variables
I got the same problem when wanna test Sign up using Facebook. After use django SSL Server from https://github.com/teddziuba/django-sslserver. This problem is solved. You may need it too.
This discussion page is really old, earlier Django does not supported SSL, it needs to be done through stunnel or Werkzeug.
Django now supports SSL configuration with django-sslserver:
https://djangopackages.org/packages/p/django-sslserver/
Add in install app and pass certs in command line.
