Installing plone.app.contenttypes, migrating from Archetypes to Dexterity

joplono · February 17, 2018, 8:32am

I want to migrate existing Archetype content to Dexterity in a Plone 4.3.6 installation.

I added
plone.app.dexterity
plone.app.contenttypes
Products.contentmigration

Version pin plone.app.contenttypes = 1.1b5

While running buildout the following error occur:

Installing instance.
The constraint, 0.7.7, is not consistent with the requirement, 'plone.app.z3cform>=2.0.1.dev0'.
While:
Installing instance.
Error: Bad constraint 0.7.7 plone.app.z3cform>=2.0.1.dev0

How can I install plone.app.contenttypes and migrate content to Dexterity in Plone 4.3.6?

First, I would use the newest version of 1.1 which is 1.1.5
Then try to pin plone.app.z3cform in your buildout config. The message means that the package has a different pinning than the requirement needs. You can override this by pinning it to the requested version or even higher if possible. Check the notes on the pypi page of the package for the possible version for your Plone version.

I pinned plone.app.contenttypes = 1.1.5

This still ends up in
Error: Bad constraint 0.7.7 plone.app.z3cform>=2.0.1.dev0

Then I pinned
plone.app.z3cform = 2.0.1.dev0

this ends up in
Error: Couldn't find a distribution for 'plone.app.z3cform==2.0.1.dev0

Then I pinned
plone.app.z3cform = 2.1

This ends up in
Error: Bad constraint 2.3.13 plone.app.layout>=2.5.22,!=2.6.0,!=2.6.1,!=2.6.2

When I pin plone.app.layout to 2.5.22 it says I need Plone 5

How can I get this working?

The best way is, to look up first where the requirements are comming from:

Version and requirements information containing plone.app.z3cform:
  [versions] constraint on plone.app.z3cform: 0.7.7
  Requirement of plone.app.dexterity<2.1.0: plone.app.z3cform>=0.7.2
  Requirement of plone.app.event[dexterity]: plone.app.z3cform>=2.0.1.dev0
  Requirement of plone.app.caching: plone.app.z3cform
  Requirement of plone.app.dexterity[relations]: plone.app.z3cform>=0.7.2
  Requirement of plone.app.registry>=1.1dev: plone.app.z3cform

  Requirement of plone.app.z3cform>=0.7.2: collective.z3cform.datetimewidget>=0.1a2
  Requirement of plone.app.z3cform>=0.7.2: setuptools
While:
  Installing instance.
Error: The requirement ('plone.app.z3cform>=2.0.1.dev0') is not allowed by your [versions] constraint (0.7.7)

As you can see, it's the plone.app.event packages which requires the newer version here.
So lets try an older one. In the readme of plone.app.contenttype you can find a list of pinnings for older Plone version like 4.3.4 which helps here to find the right version of plone.app.event. It says 1.1.4 and the newest version in that series is 1.1.11 so I would try that.

I also pinned the following versions:

plone.app.event = 1.1.11
plone.formwidget.recurrence = 1.2.6
plone.app.locales = 4.3.9
Products.PloneFormGen = 1.7.23

joplono · February 17, 2018, 11:30am

Okay, with your version pinning I got plone.app.contentypes installed via buildout, thank you!
Now when I try to install it in my Plone instance via polone_control_panel I get the following error:

gp54321 · February 17, 2018, 1:59pm

well, this change has undone you.

I don't know if some install step is supposed to add back to Plone 4 the plone.default_language registry entry that is now the official method to get the site language.
It could be possible to patch the registry but is it just getting you deeper in the mire I don't know. Maybe there is a cleaner way.

joplono · February 17, 2018, 2:40pm

What does this mean @gp54321 ?

Does it mean that plone.app.contentypes is not compatible to Plone 4, while documentation says it is?

By the way, I migrated my Plone site to Plone 5.08 which works fine.
But when I than start to migrate Archetypes to Dexterity I get key errors while migrating folders. (its a plain plone site, no custum archetypes)
So in the end I don't know how to migrate my content to dexterity as ist doesn't work in Plone 4 nor in Plone 5

tkimnguyen · February 17, 2018, 5:28pm

Does that folder exist?

gp54321 · February 17, 2018, 5:32pm

here is the last passing test for plone.app.content:
test 2 feb 2015

while the change I showed you was committed one month later.

This said, I have not looked up if the automated tests could have caught this particular problem, but anyway since they have not run successfully since this date for this particular version of plone.app.contenttypes, this is a working hypothesis at least.

You could try to change the code yourself in your Plone 4.3 instance and see if it works if yes file an issue.
About Plone 5 I think I have seen somewhere it was safer to migrate while on Plone 4 but I am not sure. As I have never even tried to use Archetypes I am not well placed to give you the best advice.

joplono · February 17, 2018, 5:56pm

Of course does this folder exist.
And if I delete it -just for testing- I get the key error on "myNextFolder"

tkimnguyen · February 17, 2018, 6:01pm

Can we see your buildout.cfg?

It is very strange that unrestrictedTraverse doesn't 'see' the object.

joplono · February 17, 2018, 6:01pm

I don't know what you mean in any detail - I am no developer, just using Plone.

You said :"it was safer to migrate while on Plone 4 but I am not sure" - well, thats why I wanted to convert to Dexterity in Plone 4 - and I opened this topic because that is not possible although I've read the documentation and did it as described.

So I now have my migrated Plone Site in version 5 with no Dexterity. (key error as described above on migration)
And I have my Plone 4.3 site that I cannot migrate from archetypes to dexterity because I cannot install plone.app.contentypes.

I am at a loss.

joplono · February 17, 2018, 6:03pm

Sure.

It's the standard buildout after using the unifiedinstaller on Linux.

Just added some addons in [eggs] and changing the port, no further changes.

But I can post it if you like.

That's a lot of add-ons to leave in there if you're trying to upgrade. Have you read this? https://docs.plone.org/manage/upgrading/index.html

As I Said, upgrading Plone from 4 to 5 went fine.

Now as my Site is Plone Version 5.08 after upgrading from 4.3 means that my content types are archetypes and I want them to be Dexterity types.

The migration via @@atct_migrator does not work.
Obviously this exception is caused by a folder to folder conversion?

This folder exists and works fine.

MigrationError: MigrationError for obj at /myPlone/myFolder (Folder -> Folder):

Have you tried Googling for migration instructions from Archetypes to Dexterity? (I looked through docs.plone.org but didn't find anything specific there, but found this http://bsuttor.herokuapp.com/2016/02/migrate-archetypes-content-types-to-dexterity among other results for "plone migrate to dexterity")

I would try it, but my code in /plone/app/contenttypes is as follows:

def _get_locales_info(portal):
language = portal.Language()
parts = (language.split('-') + [None, None])[:3]
locale = locales.getLocale(*parts)

# If we get a territory, we enable the combined language codes
if locale.id.territory:
    return locale.id.language + '_' + locale.id.territory, True, locale

return locale.id.language, False, locale

As my code original differs from yours I am not sure what to change here.

Thanks!

Regarding the link you provided I cannot believe that I have to do so much coding, just to migrate a standard Plone site with some pages, folders and images and no custom contenttypes.

I've thought standard migration is provided by Plone as is migrating Archetypes to Dexterity.
