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...

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 depend a lot on the Webbapp2 Framework to build my web apps and find it to currently be my easiest(favorite) alternative to others like Django & Flask because it integrates seamlessly with the python API for Google app engine.
I am however very worried of the fact that;
the twitter(#webapp2) last tweeted in 2011.
there is no active GitHub repo for webapp2 maintained by Google and yet Google code is turning READ ONLY!.
no new release version since 2011!
Those three reasons above have led me to think that the Project is Abandoned and might be killed eventually.
Since webapp2 (just as its predecessor webapp) was designed primarily/specifically for the GAE Python sandbox I think it's safe to assume it (or a reasonably similar replacement, if any) will remain alive for as long as GAE Python sanbox will.
Should at some point Google will decide to retire or replace it I presume they will also, as usual, provide early official notifications and ample time for migration to an alternate suggested solution before the apps relying on it will stop working.
I'd interpret the lack of activity on its codebase simply a sign of the code's quality and maturity.
WRT the Google Code going read-only it's really just a step in discontinuing Google's service of hosting sw projects, it doesn't mean development of those projects stops altogether. Development will be migrated to better project hosting services:

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://bitnami.org/cloud

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).
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 :)
In order to redeploy a GAE application, I currently have to install the GAE deployment tools on the system that I am using for deployment. While this process is relatively straight forward, the deployment process is a manual process that does not work from behind a firewall and the deployment tools must be installed on every machine that will be used for updating GAE apps. A more ideal solution would be if I could update a GAE application from another GAE application that I have deployed previously. This would remove the need to have multiple systems configured to deploy apps.
Since the GAE deployment tools are written in Python and the GAE App Engine supports Python, is it possible to modify appcfg.py to work from within GAE? The use case would be to pull a project from GitHub or some other online repository and update one GAE application from another GAE app. If this is not possible, what is the limiting constraint?
Is it possible? Yes. The protocol appcfg uses to update apps is entirely HTTP-based, so there's absolutely no reason you couldn't write an app that's capable of deploying other apps (or redeploying itself - self-modifying code)! You may even be able to reuse large parts of appcfg.py to do it.
Is it easy? Probably not. It's quite likely you'll need to understand a decent chunk of appcfg's internals, and the RPCs it uses to upload new apps - not a trivial undertaking. You'll also need to store your credentials in the app, in all likelihood - though you can use a role account that is and admin only for the apps it's deploying to minimize risk there.
One limiting constraint could be the protocol that the python sdk uses to communicate with the GAE servers. If it only uses HTTP, you might be OK. but if it's anything else, you might be out of luck because you can't open a socket directly from within GAE.
What problem did you have by trying to update behind a firewall?
I've got some, but finally I manage to work around them.
About your question, the constraint is that you cannot write files into a GAE app, so even though you could possibly pull from the VCS you can't write those pulled files.
So you would have to update from outside the GAE in first place.
Anyway every machine that needs to update the GAE should have the SDK anyway just to see if they changes work.
So, If you really want to do this you have two alternatives:
Host your own "updater" site and istall the SDK there, then when you want to update log into your side ( or run a script ) and do the remote update.
Although I don't know Amazon EC2 well, I think you can do pretty much the same thing as op 1 from there.
Finally I think the password to update has to be typed always. ( you could have the SDK of the App engine and modify that, because it is open source )
