Bugs

• exports references using pickles

• messes with the internals of the Marshal product due to lack of hooks

• uses pickles, this is not secure

• manifest XML is not yet parsed

Annoyances

• convoluted code. The code of this package needs cleanup. This will be done in due course.

Caveats

• This package out-of-the-box export AT based content only, but you can provide your own serializer as adapter

• This package does NOT export dynamically marked interfaces

• This package does NOT export annotations on content

Products.Poi

You need the branch version of Products.Marshall to handle the DataGridFields

https://svn.plone.org/svn/archetypes/Products.Marshall/branches/use-zca-in-atns

Products.eXtremeManagement

change line 44 of Products.eXtremeManagement.content.PoiTask to:

def getAssignees(self):
     managers = set()
     try:
         for issue in self.getRefs('task_issues'):
             managers.add(issue.getResponsibleManager())
     except:
         pass
     return sorted(list(managers))

because the references to the POI issues are fixed on the end of import and are not available when the object is recreated

HEAD

0.4.7 (2008-12-19)

• Fixed reference handling after import [ramonski]

0.4.6 (2008-12-16)

• Fixed tests and moved them into the source package. [seletz]

• Added fix for PloneArticle. Thanks to Freshmilk Entertainment GmbH for sponsoring this. [seletz]

• Added a events notified for ObjectWillBeExportedEvent, ObjectExportedEvent, ObjectWillBeImportedEvent and ObjectImportedEvent. [seletz]

• Added lxml and libxml2-python to the buildout. Added ZOPE-enabled ipython to the buildout. [seletz]

• Changes package layout to have the sources under src – this allows to have the buildout include development packages during development [seletz]

• Fix bug wrt. handling of blob fields. These are now treated like the file fields. [seletz]

• Added plone.app.blob to buildout to test for #10 [seletz]

• Switched buildout to plone 3.2a1 [seletz]

0.4.5 (2008-06-23)

• More importview work. [seletz]

• Fix typo [seletz]

Exporting content

To test exporting some content, we’ll create content:

>>> _ = self.folder.invokeFactory("Folder", "content")
>>> folder = self.folder["content"]
>>> _ = folder.invokeFactory("Document", "doc1", title="A Document")
>>> _ = folder.invokeFactory("Document", "doc2", title="A second Document")
>>> folder.keys()
['doc1', 'doc2']

Now we create a export context – this will act like a container holding the exported data. We’ll use the TarballExportContext here:

>>> from collective.plone.gsxml.context import TarballExportContext
>>> export_context = TarballExportContext()

Now we create a exporter object, which will use the export context created above to store the export data, and use the Marshaller to actually marshall content. We initialize the exporter with the root folder which we want to export:

>>> from collective.plone.gsxml.content import XMLContentFSExporter
>>> exporter = XMLContentFSExporter(folder)

Now we’re able to start the export. We supply the export context and a folder inside the export context (thus, one export context can be used multiple times by supplying different root folders). We also specify that this is a root-level export:

>>> exporter.export(export_context, "structure", True)

Ok, that’s it. The archive stream may now be fetched from the export context:

>>> archive = export_context.getArchiveStream()
>>> archive.seek(0)

Importing content

To test importing, we’ll delete the objects exported above:

>>> folder.manage_delObjects(['doc1', 'doc2'])
>>> folder.keys()
[]

Now we create a import context, which will hold our exported stream, and a importer, which will use that import context to read marshalled data from:

>>> from collective.plone.gsxml.context import TarballImportContext
>>> import_context = TarballImportContext(archive)

The importer – we initialize the importer with the target folder:

>>> from collective.plone.gsxml.content import XMLContentFSImporter
>>> importer = XMLContentFSImporter(folder)

Now we start the import. We supply the import context and the root folder within the import context. Also, we indicate that this is indeed a root-level import:

>>> importer.import_(import_context, "structure", True)

We’re now able to get the documents again:

>>> folder.keys()
['doc1', 'doc2']
>>> folder.doc1.Title()
'A Document'
