Somtimes useful extensions to Products.slideshowfolder

SlideshowImage

The SlideshowImage content type uses a reference to an existing normal image somewhere else in the site to act as a kind of link or alias. This allows for the creation of a folder as a slideshowfolder that displays images that are actually stored elsewhere.

Start with a couple of normal folders and a normal image.

>>> portal.images
<ATFolder at /plone/images>
>>> portal.images.contentValues()
[<ATImage at /plone/images/foo-image-title>]
>>> foo_image = portal.images['foo-image-title']
>>> folder.contentValues()
[<ATFolder at /plone/Members/test_user_1_/slideshow>]
>>> folder.slideshow.contentValues()
[<ATImage at
  /plone/Members/test_user_1_/slideshow/bar-image-title>]

Open a browser and login as a user who can add SlideshowImages.

>>> from Products.Five import testbrowser
>>> from Products.PloneTestCase import ptc
>>> portal.error_log._ignored_exceptions = ()
>>> member_browser = testbrowser.Browser()
>>> member_browser.handleErrors = False
>>> member_browser.open(portal.absolute_url())
>>> member_browser.getLink('Log in').click()
>>> member_browser.getControl(
...     'Login Name').value = ptc.default_user
>>> member_browser.getControl(
...     'Password').value = ptc.default_password
>>> member_browser.getControl('Log in').click()
>>> member_browser.open(folder.slideshow.absolute_url())

Add a SlideshowImage. Set the “Image Reference” field to the real image in the images folder.

>>> member_browser.getLink(
...     url='createObject?type_name=SlideshowImage').click()
>>> member_browser.getControl(
...     'Image Reference').value = foo_image.UID()

Since all values are taken from the referenced image, none of the normal image fields are editable.

>>> member_browser.getControl('Title')
Traceback (most recent call last):
LookupError: label 'Title'
>>> member_browser.getControl('Description')
Traceback (most recent call last):
LookupError: label 'Description'
>>> member_browser.getControl(name='image_file')
Traceback (most recent call last):
LookupError: name 'image_file'
>>> member_browser.getControl('Creators')
Traceback (most recent call last):
LookupError: label 'Creators'

Save the new SlideshowImage.

>>> member_browser.getControl('Save').click()

The values for the fields are pulled in from the referenced image.

>>> print member_browser.contents
<...
...Changes saved...
...Foo Image Title...
...Foo CreÃtor...
...Foo Image description...
>>> member_browser.getLink('Click to view full-size image')
<Link text='Foo Image Title[IMG] [IMG]
Click to view full-size image...'
url='http://nohost/plone/Members/test_user_1_/slideshow/foo-image-title/image_view_fullscreen'>
>>> member_browser.open(
...     folder.slideshow['foo-image-title'].absolute_url())
>>> print member_browser.contents
GIF...

The catalog also reflects the data from the referenced image.

>>> len(portal.portal_catalog(
...     Type='Slideshow Image',
...     Description='Foo Image description'))
1

The catalogged and indexed values for the fields are also updated when the original image is edited.

Open a browser and log in as the image’s creator.

>>> owner_browser = testbrowser.Browser()
>>> owner_browser.handleErrors = False
>>> owner_browser.open(portal.absolute_url())
>>> owner_browser.getLink('Log in').click()
>>> owner_browser.getControl(
...     'Login Name').value = ptc.portal_owner
>>> owner_browser.getControl(
...     'Password').value = ptc.default_password
>>> owner_browser.getControl('Log in').click()

Change the image metadata.

>>> owner_browser.open(foo_image.absolute_url()+'/edit')
>>> owner_browser.getControl(
...     'Description').value = 'Foo Image edited'
>>> owner_browser.getControl('Save').click()

The catalog now reflects the changes for the SlideshowImage that references the image.

>>> len(portal.portal_catalog(
...     Type='Slideshow Image',
...     Description='Foo Image description'))
0
>>> len(portal.portal_catalog(
...     Type='Slideshow Image',
...     Description='Foo Image edited'))
1

Slideshow Folders

SlideshowImages is in a folder using the slideshowfolder view behave just like regular images.

Make the folder into a slideshowfolder.

>>> member_browser.open(folder.slideshow.absolute_url())
>>> member_browser.getLink('Make slideshow').click()
>>> print member_browser.contents
<...
...This folder is now designated a slideshow...

Check that the SlideshowImage is included in the slideshow by inspecting the JavaScript. The collective.slideshowfolder package also extends the caption to include the image’s creator for credit.

>>> member_browser.open(
...     folder.slideshow.absolute_url()+'/slideshow_settings.js')
>>> print member_browser.contents
registerPloneFunction...
...http://nohost/plone/Members/test_user_1_/slideshow/bar-image-title/image_large...
...Photo: Foo Full NÃme...
...Bar ImÃge description...
...http://nohost/plone/Members/test_user_1_/slideshow/foo-image-title/image_large...
...Photo: Foo CreÃtor...
...Foo Image edited...

Slideshow Portlets

The collective.slideshowfolder package also provides a portlet that renders a Slideshow 2 in a portlet based on the contents of the first folder or collection specified in the “slideshow” refrence for the context.

Turn the a folder into a slideshowfolder.

>>> slideshowfolder = self.folder.slideshow
>>> self.loginAsPortalOwner()
>>> portal.portal_workflow.doActionFor(
...     slideshowfolder, 'publish')
>>> slideshowfolder.unrestrictedTraverse(
...     '@@folder_slideshow_view').makeSlideshow()

Open a browser and login as a user who can add SlideshowImages.

>>> from Products.Five import testbrowser
>>> browser = testbrowser.Browser()
>>> browser.handleErrors = False

Go to an area of the site without a slideshow.

>>> context = portal.news.aggregator
>>> browser.open(context.absolute_url())
>>> 'portletSlideshow' in browser.contents
False

Add a slideshowfolder reference for the context.

>>> context.addReference(slideshowfolder,
...                      relationship="slideshow")
<Reference sid:... tid:... rel:slideshow>

Now the slideshow portlet will be rendered.

>>> browser.open(context.absolute_url())
>>> print browser.contents
<...
...mootools...
...portletSlideshow...
...id="myShow"...
...registerPloneFunction...
...http://nohost/plone/Members/test_user_1_/slideshow/bar-image-title/image_large...
