Extends features and shown data in Plone document byline section

Project description

Enhance the Plone adding an additional information on document view: the user who performed the last change and the change note. Optionally expands the document byline section showing those informations.


Plone already handle lot of infos in the document byline section, like the document author, the modification date and the publication date.

In the same way new data added by this add-on will be added to the byline section.

Document byline preview in the Plone 4.3 style

When the new byline informations are shown?

New infos apart, all byline elements can now be controlled with a granular security configuration. This will change the way to handle document byline because commonly Plone simply use a couple of site-wide options: the allow_anon_views_about and the displayPublicationDateInByline.

The viewlet will now handle many different informations: author, last modifier, publication date, modification date and last versioning change note. Each information is visible if the user has a specified permission:

  • rt.lastmodifier: documentByLine view author
  • rt.lastmodifier: documentByLine view last modifier
  • rt.lastmodifier: documentByLine view modification date
  • rt.lastmodifier: documentByLine view publication date
  • rt.lastmodifier: documentByLine view change note
  • rt.lastmodifier: show long time format

To show last modifier info, Creator and Modifier must be not equals (just for not show a duplicate link).

By default Anonymous users can’t see anything (this will reproduce the Plone default behavior, where Anonymous can’t see the byline section by default).

The “show long time format” permission can enable disable the visibility of timing when dates are displayed.

Disabling byline on content types

Sometimes the byline section is displayed on contents where you don’t need it.

In that case you can apply (from ZMI) a marker interface named ILastModifierInertContent to a single content, or let your 3rd-party content types to extends it. This will disable the byline section.

Also, the byline section is automatically disabled on the Plone site root.

Show change notes

This feature will show the comment to changes you did, that commonly are kept in the history section so this only works for content type where versioning is activated.

The editor must explicitly choose if a change note must be putted in the byline section by selecting the “Show the changes note in document info” checkbox. This will store that change note to be shown in the content, that means that additional changes without checking the option will not update that information.

New change note section

To delete the change note shown you must edit a document, provide an empty note while keeping the check selected.

Note: this feature require JavaScript to work properly and has only be tested for Archetypes based content types.
