Json exporter base for Plone

Project description

Tool that exports Plone contents for a major migration.

This should be used with redturtle.importer.base/volto packages.


  • Easily to include in your old site (just add to the buildout)
  • No dependencies to other tools
  • Easily to extend (see below)

Custom exporters

This base product exports standard content-types (also Archetype-based).

If your site has some additional content-types to be exported and need to structure output in a more specific way, you can create a more specific package (for example redturtle.importer.project_name) where you can add specific exporters like this:


where GetItem class is:

from redturtle.exporter.base.browser.jsonify import GetItem as BaseGetter
class MyCustomTypeGetItem(GetItem):

    def __call__(self):

        context_dict = super(MyCustomTypeGetItem, self).__call__()
        ... do something with context_dict ...

        return get_json_object(self, context_dict)

Additional data exporter

You can add some additional data to exported json registering an adapter for ICustomDataExporter:

<subscriber factory=".my_data.ExtraDataExporter"

and in python code you need to return a dictionary with needed informations:

@adapter(Interface, Interface)
class ExtraDataExporter(object):
    order = 4  # set an execution order

    def __init__(self, context, request):
        self.context = context
        self.request = request

    def __call__(self):
        return {'foo': 'bar'}

Export users and groups

There are two additional views that can be called (only Site Managers has access to these views) to export the list of users and groups:

  • /export_users
  • /export_groups

These views returns a json with all the informations.


Install redturtle.exporter.base by adding it to your buildout:
