Dexterity behavior for file previews based on Products.ARFilePreview (WARNING: Archetypes dependencies!)

Project description


collective.filepreviewbehavior contains a behavior for using Products.ARFilePreview with dexterity content types. The views and some adapters are overwritten ARFilePreview uses some Archetypes specific stuff.

BE WARNED: If you have a dexterity setup, you may not want to install Archetypes. But Products.ARFilePreview was developed for Archetypes and may still depend on it.


Add the behavior collective.filepreviewbehavior.interfaces.IPreviewable to the behaviors list of your dexterity conten type, then the uploaded file will be converted to a HTML preview.

Use as name for the file-field “file” and mark it as primary field. The file field should be in your primary schema interfaces, a behavior schema interface may not work.

For more information about marking as primary field check out the dexterity documentation (the chapter on webdav):

The Views

Products.ARFilePreview provides three views: * file_preview : A view containg the download link and a the preview of the document embedded in the plone theme. * preview_provider : A view only containing the preview of the document. This view can be used as fullscreen / popup preview. * file_asdoc : A view only containing the preview of the document, but embedded in the plone theme.

You may the make some actions for your content, collective.filepreviewbehavior will not create any actions.



  • We should not expect the objects to provide the IBasic behavior, but we know that there is always a Title() and a Description() method (inherited from CMFCore) [26.11.2009, jbaumann]
  • MissingBinary should not fail, but skip creating the preview and put a error message into the log. [06.11.2009, jbaumann]
  • It should not fail if there is no primary field value [06.11.2009, jbaumann]
  • Added some tests, they are not working well because we test with a plain type (without any schemata and without a required file field). [23.10.2009, jbaumann]
  • Added some documentation [23.10.2009, jbaumann]
  • Initial implementation [22.10.2009, jbaumann]
