Dolmen contenttype extension : photoalbum

Project description

menhir.contenttype.photoalbum provides a single content type useable to display images as a collection. The content type has two different rendering views, allowing to render the images as static thumbnails or as an animated gallery.

Interfaces

The menhir.contenttype.photoalbum IPhotoAlbum interface extends IDescriptiveSchema from dolmen.app.content and IContainer from zope.container:

>>> from zope.container.interfaces import IContainer
>>> from dolmen.app.content import IDescriptiveSchema
>>> from menhir.contenttype.photoalbum import IPhotoAlbum

>>> IPhotoAlbum.isOrExtends(IContainer)
True

>>> IPhotoAlbum.isOrExtends(IDescriptiveSchema)
True

This interface is applied as a schema for the PhotoAlbum:

>>> from dolmen.content import schema
>>> from menhir.contenttype.photoalbum import PhotoAlbum
>>> schema.bind().get(PhotoAlbum)
[<InterfaceClass menhir.contenttype.photoalbum.album.IPhotoAlbum>]

The IPhotoAlbum interface defines a containership constraint, allowing only IImage contents, from menhir.contenttype.image:

>>> album = PhotoAlbum(title=u"My nice images")

>>> from zope.container.constraints import checkObject
>>> checkObject(album, 'temporary', object())
Traceback (most recent call last):
...
InvalidItemType: (<menhir.contenttype.photoalbum.album.PhotoAlbum ...>,
<object object at ...>, (<InterfaceClass menhir.contenttype...IImage>,))

A PhotoAlbum object provides the IPhotoAlbum interface but also the IViewSelector interface, defining the name of the view used to render the object:

>>> IPhotoAlbum.providedBy(album)
True

>>> from dolmen.app.viewselector import IViewSelector
>>> IViewSelector.providedBy(album)
True

Factory

The factory is protected by a common dolmen.app.security right:

>>> from dolmen.content import require
>>> print require.bind().get(album)
dolmen.content.Add

Icon

The content registers an icon, thanks to the dolmen.app.content package:

>>> from zope.component import getMultiAdapter
>>> from zope.publisher.browser import TestRequest

>>> request = TestRequest()
>>> icon = getMultiAdapter((album, request), name="icon")
>>> print icon
<zope.browserresource.icon.IconView object at ...>

Population

>>> import os.path
>>> from menhir.contenttype.image import Image
>>> testpath = os.path.join(os.path.dirname(__file__), 'tests')
>>> path1 = os.path.join(testpath, 'dolmen.png')
>>> path2 = os.path.join(testpath, 'dolmen-test-site.png')
>>> imagefile = open(path1)
>>> image1 = Image(title=u"Logo", image=imagefile)
>>> imagefile.close()
>>> imagefile = open(path2)
>>> image2 = Image(title=u"Example", image=imagefile)
>>> imagefile.close()
>>> from zope.component.hooks import getSite
>>> site = getSite()
>>> site['album'] = album
>>> site['album']['dolmen_logo'] = image1
>>> site['album']['dolmen_site_example'] = image2

Views

Thumbnails view

>>> print album.selected_view
thumbnails_view
>>> import fanstatic
>>> fanstatic.init_needed()
<fanstatic.core.NeededResources object at ...>
>>> index = getMultiAdapter((album, request), name="index")
>>> index.update()
>>> print index.content()
