Upgrade Plone 6 sites DX-Site-Root

1letter · September 13, 2021, 6:54am

Today in the morning i run the buildout in my Testsystem, its based on a Plone 6. Now all items are missing. Can this happend after the merge? The ZMI Root is empty:

I'm a little bit perplexed.

@1letter I think you have to run the migration for the DX site root PLIP:

## PLIP (Plone Improvement Proposal)  ## Responsible Persons ### Proposer: Roel Bruggink ### Seconder: Alessandro Pisa ## Abstract Replace the CMFPlone Portal class with a Dexterity implementation. ## Motivation Moving from a CMF item to a Dexterity container will allow us to edit the site root directly using the DX framework including support for behaviors. This makes it possible to add the rich text behavior to the site root. This way we don’t need to use extra documents to select as default views. This is the last step we need to be able to go with a full folderish objects site and get rid of the “select item as default view” which is a huge usability improvement ## Assumptions ## Proposal & Implementation Replace the base class for Products.CMFPlone.Portal.PloneSite with a DX container. Development is initially done on the latest stable (5.1) branch of Products.CMFPlone. We'll move to unstable (5.2) when this is done or if 5.2 is released, whichever is earlier. ## Deliverables PLIP buildout config can be found here: https://github.com/plone/buildout.coredev/blob/6.0/plips/plip-2454-dx-siteroot.cfg Jenkins job: https://jenkins.plone.org/view/PLIPs/job/plip-dx-siteroot-3.8/ Change Products.CMFPlone.Portal.PloneSite from CMF to DX. #2612 Various supportive changes in -at least- https://github.com/plone/plone.app.contenttypes/pull/475 and https://github.com/plone/plone.dexterity/pull/85. ## Risks Currently unknown. ## Participants Roel Bruggink Alessandro Pisa

I call: https:/mysite/portal_setup/manage_fullImport and select the profile plone.app.upgrade.v60:to_dx_site_root. I get an error:

So, @agitator and I just run into the same issue.

Ok, i got it to work. The upgrade steps runs to end. But in the ZMI all is empty. No Object.
If i call the view tab of my plone site, i got this error:

I just found: The profile alone does not run the upgrade steps.

jensens · September 13, 2021, 7:52am

Instead of applying the naked profile run upgrade steps:

scroll down

1letter · September 13, 2021, 7:54am

@jensens Yes, now, i see my objects in the zmi.

jensens · September 13, 2021, 7:54am

This is probably only a problem to all using Plone 6 already. If one comes from Plone 5.2 this would be applied in a correct way.

jensens · September 13, 2021, 8:19am

One drawback: This resets my site settings on the site root. I created a PR here to fix this https://github.com/plone/plone.app.upgrade/pull/257

After the Migration the Plone Site is now a DexterityContent Type, I get a traceback in my addon:

  File "/opt/PloneCopy/my.addon/src/my/addon/favorites/viewlets.py", line 31, in can_add_to_favorites

        # ..... some code
        if self.context.UID() not in uids:
            return True
        return False

Question: Why have my new Plone Site DX Object no UID Support? Should i do the following explicit?

from plone.uuid.interfaces import ATTRIBUTE_NAME
obj = api.portal.get()
setattr(obj, ATTRIBUTE_NAME, uuid)

alert · September 13, 2021, 8:46am

Plone sites never had a UID, this is what happens on Plone 5.2:

ipdb> api.portal.get().UID()
*** AttributeError: 'RequestContainer' object has no attribute 'UID'

I would check for the plone.uuid.interfaces.IUUIDAware interface (or for both it and IDexterityContent).

1letter · September 13, 2021, 8:50am

@alert Thanks for hint, i will check now for the IUUIDAware Interface

alert · September 13, 2021, 8:52am

I think it will be a good idea in the future to have a uid for the Plone site root.
Thank you very much @1letter for reporting these problems, we very much need it

TypeError: ('Could not adapt', <PloneSite at /mysite>, <InterfaceClass plone.uuid.interfaces.IUUID>)

Update: I patched plone.dexterity.content, line 423 with:

def UID(self):
    # Returns the item's globally unique id.
    try:
        return IUUID(self)
    except:
        print(self.id)
        # give me my plone site object id

The indexing run without errors. In the Catalog i found an Catalog Item in the Overview:
Plone Site -> /plone/portal_catalog
But is this the right way? i dont know.

I think the proper way should be to register an indexer that returns an attribute error, I filed an issue and will probably work on that tonite:

This helped also:

def UID(self):
    return IUUID(self, None)
