I am developing a Django app to run on every client computer separately. The question is, which technologies should I use to distribute such as docker, virtual machine etc.? How can I protect the Django app's code? How can I prevent to distribute without licenses?
I suggest you look into Heroku. They have a free plan too so you can test it without having to pay first. Their guide with django after you set up an app is good too. You will find everything in their documentation but if you get stuck, I recommend this video by Corey Schafer. Good luck
Edit: Heroku also supports Docker but I'm not too familiar with it. Might be useful to you

I'm relatively new to web development, but I have a couple years experience working with python, so I figured I would build my first production site using django.
I've spent the last few days learning the basics and building a test site running on my local machine. Today, I've been trying to deploy my site to production; however, I've hit a pretty large stumbling block.
The django documentation suggests using mod_wsgi for apache deployments. I followed the install instructions here, only to realize that I don't have access to make any changes to apache - I'm currently on a shared hosting plan.
Apparently, to perform the install, I would have to upgrade to a VPS plan, which costs a lot more.
Any advice for a new web developer trying to get a proof-of-concept web app together (preferably with feedback gathered from real users) on a budget?
I think I have two options:
Eat the cost on my current web hosting plan. Try to find a cheaper host that specializes in django hosting. I've been looking at the following (suggestions here would be wonderful):
Heroku
DigitalOcean
A2Hosting
Try some sort of manual deployment. Is this possible or has anybody ever made this work? I can't seem to find any resources about this.
I was able to install django on my web server and my site just seems like a collection of files at this point. Can I simply move this directory tree to my site using an ftp? And handle the database migration manually?
Can I just run django on my web server via ssh instead of from my local machine? Essentially just rebuild my site in production? I know this isn't a smart idea with a normal production site, but as a proof of concept, I don't mind some downtime if my code is buggy.
Thanks!
If you are just starting Heroku is probably perfect for you. It's super easy to set up, you don't have to handle the server configuration yourself and it has a free tier to do some tests until you are ready to go.
If you are OK with doing some more advanced server/service configuration, you can use Google Cloud, Azure or AWS. This last one has a one year free tier. If you go this route, I suggest using gunicorn/uwsgi + nginx instead of Apache mod_wsgi.
So I am quite the beginner in the world of web development. I have been working on a django application, and now that my application is running pretty well I am staring into the face of the monster that is deployment, and wondering which direction to take.
My application is running Django 1.7 and Python 3.4. I want to use PostgreSQL with Postgis as my database. I was originally thinking of using Amazon AWS for deployment, using their Elastic Beanstalk PaaS service, although now I am wondering if something like Heroku may be better for me as a beginner to all of this. I need my application to scale easily, without me having to dive into too much configuration that I am very likely to mess up.
What I am wondering is which service would be best for a newcomer developer deploying an application running the platforms I mentioned above. Heroku seems like it is a bit easier to use than AWS, but I am concerned that the pricing with Heroku would ramp up more quickly than with AWS. How difficult would it be to initially deploy using one service and migrate to another as I become more familiar with the process of maintaining web applications and/or as my needs change?
Any recommendations or info to help me decide on a service to go with would be very much appreciated.
Can I plug the company I work for, PythonAnywhere? Making Python application deployment easy is pretty much what we're there for :-)
Postgres support (including PosGIS) is currently in beta, but is pretty solid -- if you sign up, just drop us a line and we can enable it for your account.
Deploying Django service using postgres at AWS is as easy as you use local server, AWS is easy and good to use, you just need to confgiure confuguration file of Postgres and server you install at AWS. go to this https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-django-with-postgres-nginx-and-gunicorn if you are using Apache.
I have been looking at setting up a web server to use Python and I have installed Apache 2.2.22 on Debian 7 Wheezy with mod_wsgi. I have gotten the initial page up and going and the Apache will display the contents of the wsgi file that I have in my directory.
However, I have been researching on how to deploy a Python application and I have to admin, I find some of it a little confusing. I am coming from a background in PHP where it is literally install what you need and you are up and running and PHP is processing the way it should be.
Is this the same with Python? I can't seem to get anything to process outside of the wsgi file that I have setup. I can't import anything from other files without the server throwing a "500" error. I have looked on Google and Bing to try to find an answer to this, but I can't seem to find anything, or don't know that what I have been looking at is the answer.
I really appreciate any help that you guys can offer.
Thanks in advance! (If I need to post any coding, I can do that, I just don't know what you guys would need, if anything, as far as coding examples for this...)
Python is different from PHP in that PHP executes your entire program separately for each hit to your website, whereas Python runs "worker processes" that stay resident in memory.
You need some sort of web framework to do this work for you (you could write your own, but using someone else's framework makes it much easier). Flask is an example of a light one; Django is an example of a very heavy one. Pick one and follow that framework's instructions, or look for tutorials for that framework. Since the frameworks differ, most practical documentation on handling web services with Python are focused around a framework instead of just around the language itself.
Nearly any python web framework will have a development server that you can run locally, so you don't need to worry about deploying yet. When you are ready to deploy, Apache will work, although it's usually easier and better to use Gunicorn or another python-specific webserver, and then if you need more webserver functionality, set up nginx or Apache as a reverse proxy. Apache is a very heavy application to use for nothing but wsgi functionality. You also have the option of deploying to a PaaS service like Heroku (free for development work, costs money for production applications) which will handle a lot of sysadmin work for you.
As an aside, if you're not using virtualenv to set up your Python environment, you should look into it. It will make it much easier to keep track of what you have installed, to install new packages, and to isolate an environment so you can work on multiple projects on the same computer.
I want to change my static website (http://ingledow.co.uk) to a Django site on Heroku and Amazon using GitHub to store the code.
I've been through the Django tutorial once, so I'm fairly new to the whole thing.
Where would you guys start with this? Any useful books, code learning websites you could recommend to get started?
Thanks

To easily understand and visualize Heroku when hosting Django apps I created this drawing for our startup ChattyHive. I hope it is helpful. Don't hesitate on asking me any doubt or suggest anything :)
(please right clic on it and "view picture" to see it full size or it will be too small!)
The best way to learn Python and Django is to be comfortable with creating a proper environment for developing your application, although you can skip the details and start with Heroku's official guide on how to manage a Django application across the whole stack.
At the time of writing, these are some of the essential tools Python developers should be comfortable with:
virtualenv for creating distinct copies of the Python interpreter and it's environment
pip for managing Python dependencies
fabric for defining administrative tasks across all your target environments
puppet or chef for provisioning environments
vagrant for provisioning development environments
I would suggest that you immediately familiarize yourself with vagrant and focus on the virtualenv+pip+fabric trio--these are ubiquitously utilized in any Python web project and your bound to be forced to come to terms with them sooner or later, so get straight to it and you'll be otherwise amazed how you ever managed any Python development without them.
As far as learning Django is concerned, you will need to understand that Django is still just plain-old Python, what WSGI applications are, how domain objects are modeled, how Django routes requests, how views handle requests and how they produce responses, including additional and intermediary framework components. Afterwards, you should be knowledgeable enough to start tackling any requirements you might have of your application.
I will stress that having a good grasp on Python goes a long way in helping you understand how Django was designed and how to better write and organize your application's sources. The documentation is pretty exhaustive and it's the primary resource for any developer, but if you find yourself in need, there are several good books written that focus on providing additional material on certain aspects, but never forget to hone your Python skills.
Worth mentioning is the Django Package index which tracks any Python package specifically written to be integrated with Django. Their repositories are publicly accessible either on Github or Bitbucket and they range from tiny to huge and are an invaluable resource to see how other developers are doing Django development right.
Maybe you should start with some introduction books about Django,like The Django Book.
I dont know if at all i make any sense, but this popped up in my mind. Can we use the 2gb free hosting of dropbox to put our django app over there and do some hacks to run our app?
No, it's not possible.
If you want to use dropbox as the hosting, you can put static pages, meaning just the html files with CSS and javascript because those files can be retrieved by doing a simple GET request.
Hosting a python code is not possible as it requires server side calculations & dropbox is just for saving files.
See the official wiki for the available hosts. https://code.djangoproject.com/wiki/DjangoFriendlyWebHosts
The point you need to understand is: can you run django without djagno installed? Can django be installed on a usb-drive? Dropbox is but a cloud storage service NOT cloud hosting service. To store you do not require RAM and processors while for hosting you do.
Hence the answer is NO. If you are okay with configuring apache etc. you can go for VPS. If not try some managed servers. If you dont want to spend much and are looking at free hosting solutions for django a few of them are:
kodingen.com
shellmix.com
http://0x2a-dc.com/index.php?name=shop&cat=6
http://www.heliohost.org/home/
http://bitnami.org/cloud
https://www.alwaysdata.com/
more data:
http://freedjangohosting.com/
http://djangohosting.com/
https://code.djangoproject.com/wiki/DjangoFriendlyWebHosts
Yes its possible! PythonAnywhere.com offers that!
What pythonanywhere does is pretty simple. They integrate your dropbox account with their one. When you want to create a Django app, all you got to do is, direct the platform to store the app in your dropbox folder!
Now, you can open your Django app in your PC and edit it (wait for some time to sync)..restart the app, it works! I practically tried.
Tip: There are many cloud platforms which offer great services for free. Openshift, Heroku, Google App Engine are to name a few!
No, you can't use DropBox to serve a Django Website, as doing so requires Python code to be run, when DropBox is only for saving & serving files.
You can, however, find free hosting for your Django needs, among which:
Heroku, originally meant for Ruby hosting, but now allows you to do Python hosting. I didn't find it particularly easy to use with Django though.
ep.io, Python-specific hosting, but invite-only for the moment - it's possible to get an invite by sending an email, explaining your project & your needs though. Offers you free SSL on *.ep.io, which is pretty nice, and they've got great service.
Dotcloud, not platform specific, but my personal favorite. It's pretty easy to get started, and the CLI allows you to do a lot (but the downside is that you need it a lot too). If you're not afraid of CLI, it's great.
Being said its not possible from dropbox to do that you can use very simple cloud hosting as told ahead,
I might be late for answer but you can get free cloud hosting from Linux Fedora company called RedHat. Their cloud product is available for free which supports django hosting. I tried it my own
Openshift Free Cloud Hosting
In addition to what Thomas posted, some other options for free django hosting:
Amazon Compute Instance (free for one year, free sign up).
Google App Engine (free limits,django howto).
OpenShift (django howto).
