Store references on an object and not in the reference catalog

simplereferencefield is an Archeteyps reference field implementation that stores the references directly on the object without indexing it in the reference_catalog.

Create a document that references news.

>>> self.loginAsPortalOwner()
>>> self.portal.invokeFactory('Document', 'doc1')
'doc1'
>>> doc = self.portal['doc1']
>>> doc.setRelatedItems(self.portal.news)
>>> doc.reindexObject()
>>> doc.getRelatedItems()
[<ATFolder at /plone/news>]

The document has a relationship.

>>> doc.getRelationships()
['relatesTo']

Change relatedItems in the document’s schema to be a SimpleReferenceField.

>>> from Products.ATContentTypes.content.document import ATDocument
>>> from upfront.simplereferencefield import SimpleReferenceField
>>> ATDocument.schema['relatedItems'] = SimpleReferenceField(
...   'relatedItems', relationship='relatesTo', multiValued=1)
>>> ATDocument.schema['relatedItems'].type
'simplereference'

Create a document that references news.

>>> self.portal.invokeFactory('Document', 'doc2')
'doc2'
>>> doc = self.portal['doc2']
>>> doc.setRelatedItems(self.portal.news)
>>> doc.reindexObject()
>>> doc.getRelatedItems()
[<ATFolder at /plone/news>]

The document has no relationships.

>>> doc.getRelationships()
[]

If we reference doc1 from doc2, doc1 will have doc2 set as back reference.

>>> self.portal.doc2.setRelatedItems(self.portal.doc1)
>>> self.portal.doc2.getRelatedItems()
[<ATDocument at /plone/doc1>]
>>> self.portal.doc1.getRelatedItems()
[<ATDocument at /plone/doc2>]

Back references are set by default but can be disabled.

>>> ATDocument.schema['relatedItems'] = SimpleReferenceField(
...   'relatedItems', relationship='relatesTo', multiValued=1,
...   set_backreference=False)
>>> self.portal.invokeFactory('Document', 'doc3')
'doc3'
>>> self.portal.doc3.setRelatedItems(self.portal.doc1)
>>> self.portal.doc3.getRelatedItems()
[<ATDocument at /plone/doc1>]
>>> self.portal.doc1.getRelatedItems()
[<ATDocument at /plone/doc2>]
