Project description


  • Adds a slideshow to dexterity folderish types

  • Adds a media view that shows the first image of the slideshow in folders and collections

How it works

An administrator can choose which types are upgraded with slideshow functionality by adding a ‘slideshow’ behaviour via the ‘Site Setup’/’Dexterity content types’. A folder named ’slideshow’ appears inside of items with slideshow behaviour. Using drag and drop functionality multiple images can be uploaded to the slideshow folder. A slideshow with the several images appears automatically in the view of any item that contains more than one image int the ‘slideshow’ folder. In case the folder contains only one image, the view shows the image but not the next/previous buttons. In case the folder contains no images, the slideshow does not appear in the page.

Videos from YouTube and Vimeo can also be added to the slideshow. Create an item of type link inside the slideshow folder pointing to the video on youtube or Vimeo. Make sure the URL is a canonic YouTube or Vimeo url.

Implementation details

  • Folderish content types are adapted with ICanContainMedia interface that provides MediaHandling class. This class adds functionallity to set the leading media.

  • There is two FieldIndex and metadata added to portal_catalog: hasMedia (True/False) and leadMedia (UID of the leading picture).

  • An event handler is added to folderish content types and is triggered on modified events. This event updates the indexes in the portal_catalog.
