collective.cover 1.7b5

Demo

For impatient types, there is a demo installation of collective.cover on Heroku. It needs about 60 seconds to spin up and it will purge all changes after about an hour of non-usage.

Use cases

Suppose you are running The Planet, a news portal that has a bunch of editors focused on getting news on different topics, like Economy, Health or Sports.

If you are the main publisher of the site, you may want to delegate the construction of the front page of the Economy section to the people working on that content area, but you might not want them messing around the Sports section as well.

Also, suppose you have the final game of the World Cup and the match is going to be defined on penalties: you may want to prepare a couple of cover pages and publish the right one focused on the team that won in the end.

These are the kind of issues we want to solve with this package; we are still far from it, but that is the idea.

Who is using it?

These are some of the sites using collective.cover:

• CartaCapital (BR)

• Clean Clothes Campaign (NL)

• Conselho Federal de Administração (BR)

• La Jornada (MX)

• Palácio do Planalto (BR)

• Portal Brasil (BR)

• Rede Brasil Atual (BR)

• Venezolana de Televisión (VE)

• European Climate Adaptation Platform (EU)

Known issues

• Not compatible with Plone 5; see the list of related issues if you want to help.

• Package is not compatible with standard Plone tiles. This will be addressed in a future release, if we get an sponsor.

See the complete list of bugs on GitHub.

Installation

To enable this package in a buildout-based installation:

Edit your buildout.cfg and add add the following to it:

[buildout]
...
eggs =
    collective.cover

[versions]
...
collective.js.bootstrap = 2.3.1.1
plone.app.blocks = 4.2.0
plone.app.tiles = 3.1.0
plone.tiles = 2.1

If you want to use a newer release of collective.js.bootstrap, you will need to update plone.app.jquery:

[versions]
plone.app.jquery = 1.8.3

After updating the configuration you need to run ‘’bin/buildout’’, which will take care of updating your system.

Go to the ‘Site Setup’ page in a Plone site and click on the ‘Add-ons’ link.

Check the box next to collective.cover and click the ‘Activate’ button.

1.6b5 (2017-11-21)

• Fix purging of tile annotations when removing tiles from the cover layout. This solves exponential growth of cover objects when using versioning, leading to check in/check out (plone.app.iterate) timeouts on backends using proxy servers (fixes #765). [rodfersou]

• Do not auto include package dependencies, but declare them explicitly. [hvelarde]

1.6b4 (2017-10-30)

1.6b3 (2017-10-23)

• Fix edit view of carousel tile when one carousel item has a unicode character in its title (fixes #757). [fulv]

• Explicitly declare cover_layout field in content type schema as readonly; Robot Framework tests pass again with latest version of Plone 4.3 (fixes #759). [hvelarde]

1.6b2 (2017-09-01)

• Use correct image/x-icon MIME type for ICO file format (fixes #750). [hvelarde]

• Fix IDatetimeWidget tile override if using plone.app.contenttypes >= 1.1.1: collective.z3cform.datetimewidget is merged into plone.formwidget.datetime, so the zcml must override the template from plone.formwidget.datetime.z3cform.interfaces.IDatetimeWidget as well. (closes #745). [idgserpro]

• Review tile refresh using custom event. [rodfersou]

1.6b1 (2017-06-23)

• Fix typo in basic tile template (is_empty is not a property but a function). [hvelarde]

1.5b1 (2017-06-12)

• Information stored on basic tiles populated with private content is no longer shown to users without proper permissions (fixes #721). [hvelarde]

• Dropping a folder on a carousel tile no longer populates the tile with the items inside the folder; populating the carousel tile with the results of the query in a collection is still supported. [rodfersou, hvelarde]

• Dropping a folder or a collection into a list tile previously resulted in the tile being populated with the items inside the folder or the results of the query in the collection, making impossible to have folders or collection as items of the list tile themselves (fixes #713). [rodfersou, hvelarde]

• Update recommended versions of Blocks dependencies to keep in sync with current Mosaic development. [hvelarde]

• Fix order of UUIDs of sorted function in ListTile’s ‘results’ method. [idgserpro]

• Review content chooser events to happen just at Compose tab (fixes #710). [rodfersou]

• Do not assume all tile types have schemas. [alecm]

• Do not declare the Cover class as an implementer of IDAVAware; This makes absolutely no sense and is causing an error when doing a GenericSetup export (fixes #396). [hvelarde]

1.4b1 (2016-12-14)

• Fix @@updatetilecontent view to avoid rendering outdated data. [hvelarde]

• Fix TypeError when changing default image scale on basic tiles (fixes #686). [rodfersou]

• Fixed adding a ‘more’ link in list tiles. Previously you could select an item to use as ‘more’ link, but it did not stick. [maurits]

• The replace_with_objects method was removed from the list tile; use replace_with_uuids instead. [hvelarde]

• “Add Content” button is now shown also in Plone 5. [hvelarde]

• Avoid exceptions while using the content chooser in Plone 5. [hvelarde]

• Add helper function to get the human representation of a mime-type on Dexterity-based content types. This fixed an AttributeError that was causing an exception on Plone 5. [hvelarde]

• We now get the types that use the view action in listings in Plone 5 also. [hvelarde]

• ESI support was refactored; now all tiles inherit from ESIPersistentTile by default. [hvelarde]

• Add plone.protect when save layout (fixes #651). [rodfersou]

• Use pat-modal instead of prepOverlay for Plone 5 (fixes #641). [rodfersou]

• Enforce usage of plone.app.tiles >= 1.1.0 to avoid creation of zillions of empty blob files when using versioning (fixes #532, huge HT @datakurre). [hvelarde]

1.3b1 (2016-09-12)

• Update Traditional Chinese translation. [l34marr]

• Remove dependency on five.grok (closes #510). [l34marr, rodfersou]

• Use the X-Robots-Tag header to avoid indexing of image scales on default view; this will reduce the number of 404 (Not Found) responses generated by crawlers visiting the site in search of volatile content. [hvelarde]

• Enforce usage of plone.api >= 1.4.11 to avoid TypeError while running upgrade step to profile 14. [hvelarde]

1.2b1 (2016-07-04)

• A new calendar tile was added. The tile dislays a calendar that highlights the events taking place on the current month, the same way as the standard calendar portlet does. [rodfersou]

• Handle AssertionError on upgrade step to profile 13 to avoid failures when a cover object has duplicated tiles on it. Now, an error message will be logged and the object will be skipped; you must manually remove the duplicated tiles (closes #619). [hvelarde]

1.1b1 (2016-03-31)

• Enforce usage of plone.app.blocks 2.2.1 to avoid issues with tiles breaking the whole cover page. [hvelarde]

• Add option to select random items in collection tile (closes #608). [rodfersou]

• Carousel tile now uses a relative ratio to set its height (fixes #414). [terapyon, hvelarde]

• Remove hard dependency on plone.app.referenceablebehavior as Archetypes is no longer the default framework in Plone 5. Under Plone < 5.0 you should now explicitly add it to the eggs part of your buildout configuration to avoid issues while upgrading. [hvelarde]

• Link integrity was refactored to work on all tiles and under Plone 5; a hard dependency on Products.Archetypes was removed (fixes #578). [hvelarde, rodfersou]

• Do not use the calendar tool to discover Event-like objects as it was removed on Plone 5. Instead, try to guess if an object is an Event by using its catalog metadata. [hvelarde]

• Package is now also tested with plone.app.contenttypes installed; a few bugs related with API incompatibilities among Archetypes and Dexterity were fixed. [hvelarde]

• Remove Grok dependency for vocabularies. [l34marr]

• You can now use a collection to populate a carousel tile; search results without a lead image will be bypassed (fixes #574). [rodfersou]

• Shows message to user if an exception is thrown in a tile in AJAX calls. (closes #581). [idgserpro]

• Fix date format in collection tiles (closes #584). [tcurvelo]

• RichText tile no longer breaks with plone.app.widgets installed (closes #543). [frapell, rodfersou]

• Add missing dependency on collective.z3cform.datetimewidget. [hvelarde]

• Remove hard dependency on plone.app.stagingbehavior as that package is no longer needed in Plone 5. Under Plone < 5.0 you should now explicitly add it to the eggs part of your buildout configuration to avoid issues while upgrading. [hvelarde]

• Implement drag and drop among tiles (closes #487). [rodfersou]

• Clean up static files. [rodfersou]
