Is it possible to eliminate the desktop and fully code and deploy a python/django application to the cloud from within a browser? I think Heroku makes it possible to do that with Ruby on Rails but I have not come across a Python/Django equivalent.
I think there are huge advantages of developing code in the cloud. No deployment overhead, no code versioning headaches (because the cloud will track all changes anyway), access your code from anywhere, even an iPad, if you want to make a small change to your production code. I think Heroku has already proven that this is the future of web development and browser based IDEs like Mozilla Bespin are already getting some traction.
I'm not really sure that Heroku does that, it just a cloud space for Rails.....like phpfog (php), dotcloud (many), appengine (java, python)....
I think http://kodingen.com/ is something more like what you ask, code in the web and deploy on it.....
Haven't tried Kodingen though....
As an updated answer to #jjchiw, Koding provides a you with Python2 and Python3, and gives you root access to a full Ubuntu VM, so everything will work just like you expect :)
I say updated, because Kodingen turned into Koding a year ago, and is under very active development.
Let me know if you have any questions :)

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.
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.
As an experienced PHP programmer I tend to avoid things like Python. However we all must play with the cards we have been dealt with and I now have to work with a Satchmo website.
I have very little python, django and satchmo so I need some help. I'm ok with setting up a development server but I cannot get my website to work on a production server.
I've seen the use of "python manage.py runserver", this solution is even on Stack Overflow. However, when I see this solution there is usually someone saying "I hope you're not using that on production" so I assume this is a very incorrect way to do it. To my frustration the people that seem to know that this command line is insecure, also have no desire to share with the rest of us, just how excatly does one initiate their Satchmo Production server?
Many thanks.
To deploy a Django website on a production server, you have to serve it either with Apache+mod_wsgi, nginx+gunicorn, nginx+uwsgi, or any other server supporting WSGI. The Django documentation has a page on deploying Django on Apache with mod_wsgi, for the other solutions, there are plenty of useful documentation around the web.
runserver is just for development/testing. It won't handle high load, security, etc.
Python.org has docs on how to set up a proper webserver to serve Python code:
http://docs.python.org/howto/webservers.html
Satchmo seems like a django derivative. Setting up django on production is quite easy if your deployment environment is linux with apache then use mod_wsgi which is well documented here if its windows then you can use the pyisapie module and follow the documentation here
Hope that helps
Anyone have any thoughts on how/if it is possible to integrate Google Code commits to cause a Google AppEngine deployment of the most recent code?
I have a simple Google AppEngine project's source hosted on Google Code and would love if everytime I committed to Subversion, that AppEngine would reflect the latest commit. I don't mind if things are broken on the live site since the project is for personal use mainly and for learning.
Anyone have any thoughts on how to tie into the subversion commit for the Code repository and/or how to kickoff the deployment to AppEngine? Ideally the solution would not require anything manual from me nor any type of server/listener software on my machine.
Google Code Project Hosting now supports Post-Commit Web Hooks, which ping a project-owner-specified URL after every commit. This would eliminate the need to regularly poll your Google Code repository.
Made By Sofa had a blog post about their workflow with Google App Engine. In the second last paragraph they have attached a subversion hook that when when someone commits code it will automatically deploy to Google App Engine. It would take a little bit of tweaking (because it works on the server side not the client) but you could do the same.
You'd probably have to have some glue on another computer which monitored SVN commits and deployed a new version for you. Google Code has yet to develop and release an API (which they need to do soon if they're serious about this whole development thing), but GAE can be deployed to with relative automated ease, so I wouldn't have thought it should be that difficult. The deployment process, however, will vary with each project, so that's something you need to sort out yourself (you might wanna take a look at the fabric deployment system). Then, just set a cron job going which updates a local SVN checkout on the middle machine, and you're done.
Very interesting, but not yet possible, AFAIK. I have been looking for that option in Google Code with no success.
The only solution I can figure out is to install something in your machine that checks for changes in your SVN repository.
I'll be happy to hear about other approaches.
For those of us who are using Github, this feature from the GAE team would make us all seriously consider switching to Google Code...
