collective.regjsonify 0.3.0

Export Plone registry content to a JSON compatible Python structure

Introduction

Quickly export the content of a Plone registry configuration (defined by an interface) in a Python structure compatible with JSON format:

import json
from collective.regjsonify.interfaces import IJSONifier
from plone.registry.interfaces import IRegistry
from zope.component import queryUtility

registry = queryUtility(IRegistry)
settings = registry.forInterface(IYouInterfaceSettings)
python_data = IJSONifier(settings).json()
json_data = json.dumps(python_data)

Extending

The package came with a default set of know data types that cover common fields used in Plone registry. However this set can be not complete if you are using a not supported field type.

During export operation unknown data are ignored.

If you want to export other types you must manually provide the proper IJSONFieldDumper adapter:

<adapter
  factory="your.package.YouExportAdapter"
  provides="collective.regjsonify.interfaces.IJSONFieldDumper"
  for="3rd.party.field.interfaces.INewFieldType"
  />
