If you make a browser view, I think you should be all right

For that, you will need a zcml file with something like this:
https://github.com/espenmn/medialog.redirect/blob/master/src/medialog/redirect/browser/configure.zcml <https://github.com/espenmn/medialog.redirect/blob/master/src/medialog/redirect/browser/configure.zcml>

(but please, change the «permissions» line)

Then you need the view itself, like this (but with your code):
https://github.com/espenmn/medialog.redirect/blob/master/src/medialog/redirect/browser/view.py <https://github.com/espenmn/medialog.redirect/blob/master/src/medialog/redirect/browser/view.py>

If that too sound too complicated, try downloading the whole product and
1) Search & replace ‘medialog’ with ‘your name’ and
2) search & replace ‘redirect’ with ‘yourproductname’ in files and filename
3) Open every file, one by one, you will like be able to guess if anything should be changed
4) Put your add-on ( your name.yourproductname) in /src folder
5) Add egg = yourname.productname and src = src/yourname.productname  to buildout.cfg
6) Run bin/buildout
7) (re)start phone and 
8) install the add-on
9) run the browser view ( http://site/@@browserviewname <http://site/@@browserviewname>)

( or you could read ‘everything about browser views and do it ‘properly’)

PS: I am not a ‘python expert, so if other have suggestions, that is probably better .

> I have been googling this and I came across something that said you have to use an external method to have full permissions to run certain code.  Later I came across another posting that said external methods are obsolete and one should use views.  I am quite confused right now.  Can someone point me in the right direction and how I should go about doing it?
