how to import a python module in a jython script

[Marianne]

Hi All,

I want to do some cleaning of user input so I can be confident in displaying some of the input text as HTML. I know of a python module which will let me easily do this - bleach (http://bleach.readthedocs.org/en/latest/clean.html). I would like to use bleach.clean() in my details.py Jython script. Obviously I need to install bleach, and its dependency html5lib, somewhere that is findable by Jython for the import bleach statement to work.  What do I need to do? Pointers to websites/docs welcome.

Thanks!

Marianne

Hi Marianne,

 

I’m not a python expert, but at a guess I’d say you need to include the directories that contain the python libraries on your Python Path.

 

Have a look at these web pages for more info:

http://www.jython.org/archive/22/userfaq.html#my-modules-can-not-be-found-when-imported-from-an-embedded-application

http://stefaanlippens.net/jython_and_pythonpath

 

I hope that helps,

Mike

I guess I was wondering if there was a right way to do this for the ReDBox application. 

• Is there a config file with a python path property already set? Have looked in tf_env.sh and it isn't set there. I've printed out the sys.path and seen what it is set to and it is all local to the $PROJECT_HOME area as expected.
  
• Is there a right place to install the python modules? (e.g. I was thinking server/lib as it contains all the jar files but is there a "best practice" way to do this - ? a python folder inside the server/lib )

Obviously I'll have to fiddle with our deployment script so that anything I manually do now on my local dev instance will be reproduced when installing on the test server and the production server. 

I have only been fiddling round the edges of ReDBox so far - velocity templates etc. Haven't delved into all the config files etc yet.

Hi Marianne,

I created home/lib to store libraries for the alerts work: https://github.com/redbox-mint/redbox/tree/master/config/src/main/config/home/lib

You'll see in the following script how I setup the path (line 6): https://github.com/redbox-mint/redbox/blob/master/config/src/main/config/portal/default/redbox/scripts/hkjobs/newalerts.py

You should be able to add to home/lib/jython in your local build and have it deploy. Don't forget that we're running jython so you'll be a little limited in terms of python coding and libs - I think our Jython jar supports Python 2.5. 

It can be handy to setup some testing scripts to save time - checkout my dodgy doco that details how I did this: https://github.com/redbox-mint/redbox/tree/master/config/src/main/config/home/lib/jython/alertlib/test

I hope that ramble's of some use.

Cheers,

Duncan
