Django on Jython, PyCon 2009
- 1. Django on Jython Jim Baker Leo Soto
- 5. setuptools
- 6. virtualenv
- 7. nose
- 8. etree
- 11. web 2 py
- 14. Django + Jython: Why?
- 15. Installing this Django app...
- 16. ...in an Enterprise Infrastructure
- 17. (I mean, this kind of enterprise infrastructure)
- 18. Didn't work quite well
- 19. Guess how much time it took
- 20. We like Python They need Java
- 21. Jython
- 22. Avoiding Java Sneaking Python Is that it?
- 23. No, it is more than that! (if you want)
- 24. Examples...
- 25. Python/Django Install Django Install 3rd party deps Install app(s) Tweak settings.py Configure web server Make sure everything is consistent Steps to Deploy a Web Application
- 26. Java Copy/upload WAR package Steps to Deploy a Web Application
- 27. Java libs can eat complex Excel data!
- 28. We can reuse what's good on the Java ecosystem!
- 29. Django + Jython: Architecture
- 30. The cool side of Java System Programming Concurrency Model Memory Model
- 31. $ jython2.5 ... >>> from __future__ import GIL
- 32. $ jython2.5 ... >>> from __future__ import GIL Traceback (most recent call last): (no code object) at line 0 File "<stdin>", line 1 SyntaxError: Never going to happen!
- 33. On the other hand...
- 34. J2EE was a big, horrible mistake
- 35. The right tool for the right job!
- 36. Java : Performance, Heavy lifting, Pre-existing infrastructure
- 37. Jython : Everything else :)
- 38. Deployment
- 39. App Servers: Already there, lots of features
- 40. Let's use their force! http://flickr.com/photos/tomloudon/322172413/sizes/l/
- 41. Deployment Options Java app servers - show some horizontal scaling; also management - sys admins know how to do this! Hardened - it runs on the JVM
- 42. vs Google App Engine It’s Django 1.0 We have Unicode, internationalization, ORM, unit tests, admin, shell, everything! And we can use Java analogues: BigTable <=> HBase, Hypertable MapReduce <=> Hadoop Add pictures for app engine, HBase, Hadoop
- 43. WAR! Web ARchive format Standard deployment for Java app servers Just a bunch of files with a standard directory layout and manifest
- 44. $ jython manage.py war --include-java-libs=jdbcdriver.jar
- 46. WAR format for DoJ |-- WEB-INF | |-- lib | `-- lib-python | |-- Lib | |-- django | |-- doj | `-- mysite `-- media super simple bundling!
- 47. IDE Integration
- 48. Again, why?
- 49. Quick Start!
- 51. Re-factoring
- 52. One place to rule them all
- 53. Let see how that'd be with Django...
- 54. Demo
- 55. Summary
- 56. Questions?
