Question

I am writing a python script to import content from another CMS into Plone 4.1. For a number of reasons I am running it like so: bin/instance run path/to/myscript

The question I have is how to get the correct context for a folder with a hyphen in the ID/shortname. For example from the root of a plone site called mysite, I can work with a folder called “sub-folder” like so:

from Products.CMFCore.utils import getToolByName
urltool = getToolByName(app.mysite, "portal_url")
portal  = urltool.getPortalObject()
folder = getattr(portal, 'sub-folder')

But if I then want to create a folder or page within that sub-folder, the following throws an error: “AttributeError: sub”

urltool = getToolByName(app.mysite.sub-folder, "portal_url")
portal  = urltool.getPortalObject()

And performing the same on the News folder, (which has no hyphen) produces no error:

urltool = getToolByName(app.mysite.news, "portal_url")
portal  = urltool.getPortalObject()

Simply trying portal.sub-folder throws the same Error.

So what would be the python code to get the proper context of “http://localhost:8080/mysite/sub-folder” so that I can then successfully call the invokeFactory method and create a folder or page within mysite/sub-folder?

What if I needed to find the context of “http://localhost:8080/mysite/sub-folder/2nd-level” ?

The online documentation I have found seems to only account for folders named dog or news, which have no hyphen in the ID/Shortname. However, if you create these items by hand in Plone, the shortnames obviously have hyphens, and so there must be a way to get the correct folder context.

Answer 1

That’s because if you use:

app.mysite.sub-folder

python thinks that you’re trying to do a difference between app.mysite.sub and folder.
Instead you have to use this syntax:

secondlevel = mysite['sub-folder']['2nd-level']

or

secondlevel = mysite.restrictedTraverse('/mysite/sub-folder/2nd-level')
