How to edit the value of a paper field programmatically

I wrote this how-to after I had to decrement the value of "articleform" field in all submitted papers (articles) because of the change in the vocabulary.

Create a Python script in your custom skin folder similar to the one bellow. Modify to fit your needs. Test and run. Enjoy ;-)

from Products.CMFCore.utils import getToolByName
urltool = getToolByName(context, 'portal_url')
portal = urltool.getPortalObject()
articles_container = portal.conference.Articles
articles = articles_container.folderlistingFolderContents(['Article'])

for a in articles:
    print a.title_or_id()
    print a.articleform
    # uncomment the following line to modify the value of the field
    #a.setArticleform(a.articleform - 1)

return printed
