Base indexes

The dolmen.app.content.indexes.BaseIndexes handles the title and the content type of an IBaseContent content:

>>> indexes.BaseIndexes.__grok_indexes__
{'content_type': <grok.index.Field object at ...>, 'title': <grok.index.Text object at ...>}

>>> indexes.BaseIndexes.__grok_indexes__['content_type']._attribute
'__content_type__'

Searchable text

dolmen.app.content provides a simple ‘ISearchableText’ implementation, allowing full text searches. It comes in two parts.

The index:

>>> indexes.SearchableIndex.__grok_indexes__
{'searchabletext': <grok.index.Text object at ...>}

The adapter:

>>> from zope.index.text.interfaces import ISearchableText
>>> adapter = ISearchableText(manfred)
>>> adapter.getSearchableText()
u'A nice mammoth'

Scales

Let’s introspect our Miniaturizer component:

>>> from dolmen.app.content import thumbnails

>>> thumbnails.BlobMiniaturizer.factory
<class 'dolmen.blob.file.BlobValue'>

>>> print thumbnails.BlobMiniaturizer.scales
{'mini': (250, 250), 'square': (64, 64), 'thumb': (150, 150), 'large': (700, 700), 'small': (128, 128), 'preview': (400, 400)}

The new scale, ‘square’, scales down and crops the original image to provide a square thumbnail. This is done using a IThumbnailer adapter:

>>> from dolmen.thumbnailer import IThumbnailer
>>> thumbnails.SquareThumbnailer
<class 'dolmen.app.content.thumbnails.SquareThumbnailer'>
>>> IThumbnailer.implementedBy(thumbnails.SquareThumbnailer)
True
