Dolmen contenttype extension：photoalbum
menhir.contenttype.photoalbum的Python项目详细描述
menhir.contenttype.photoalbum提供单个内容类型 可将图像显示为集合。内容类型有两个 不同的渲染视图，允许将图像渲染为静态 缩略图或作为动画库。
接口
menhir.contenttype.photoalbumiphotoalbum接口扩展 idescriptiveschemafromdolmen.app.content和icontainerfrom 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
此接口作为相册的模式应用
>>> from dolmen.content import schema >>> from menhir.contenttype.photoalbum import PhotoAlbum >>> schema.bind().get(PhotoAlbum) [<InterfaceClass menhir.contenttype.photoalbum.album.IPhotoAlbum>]
iphotoalbum接口定义了一个containership约束， 只允许从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>,))
一个photoalbum对象提供了iphotoalbum的接口 iviewselector接口，定义用于 渲染对象：
>>> IPhotoAlbum.providedBy(album) True >>> from dolmen.app.viewselector import IViewSelector >>> IViewSelector.providedBy(album) True
工厂
工厂受公共dolmen.app.security权限保护：
>>> from dolmen.content import require >>> print require.bind().get(album) dolmen.content.Add
图标
由于^{tt3}，内容注册了一个图标$ 套餐：
>>> 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 ...>
人口
>>> 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
视图
缩略图视图
>>> 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() <h1>My nice images</h1> <div class="photo-album"> <div class="gallery-thumbs"> <ul class="thumbs noscript"> <li> <a class="thumb image-link" href="http://127.0.0.1/album/dolmen_logo/++thumbnail++image.preview" title="Logo" rel="gallery-..."> <img src="http://127.0.0.1/album/dolmen_logo/++thumbnail++image.square" title="Logo" alt="Logo" /> </a> </li> <li> <a class="thumb image-link" href="http://127.0.0.1/album/dolmen_site_example/++thumbnail++image.preview" title="Example" rel="gallery-..."> <img src="http://127.0.0.1/album/dolmen_site_example/++thumbnail++image.square" title="Example" alt="Example" /> </a> </li> </ul> </div> </div>>>> fanstatic.get_needed().resources() [<Resource 'css/slimbox2.css' in library 'jquery_slimbox'>, <Resource 'gallery.css' in library 'photoalbum.resources'>, <Resource 'jquery.js' in library 'jquery'>, <Resource 'js/slimbox2.js' in library 'jquery_slimbox'>, <Resource 'popup.js' in library 'menhir.contenttype.image'>]
