Who is using it?

These are some of the sites using collective.liveblog:

• CartaCapital (BR)

• Portal Brasil 2016 (BR)

Installation

To enable this package in a buildout-based installation:

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

   [buildout]
   ...
   eggs =
       collective.liveblog

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.liveblog and click the ‘Activate’ button.

Usage

After installing the package you will see a new content type available: Liveblog.

Liveblogs have title, description, image and text fields. The image field is used to set up a header on the liveblog.

Now, go to the Update tab and start writing micro-updates.

A micro-update is basically a text that should optionally have a title. The date and time of the micro-update is automatically recorded for you. After publishing a micro-update you will see it on top of your liveblog before all previous micro-updates.

All people viewing your liveblog will receive automatic updates every minute.

Micro-updates can be viewed as separate pieces of content, using the link in their timestamp, making easy to share them in social networks.

Many editors can update the liveblog safely. When another editor adds a micro-update you will see it automatically on your screen even if you are writing a new one.

You can delete micro-updates also. This will trigger a complete page refresh on all current viewers to avoid the displaying of invalid content in your liveblog. The page refresh will happen withing the next minute. If another editor deletes a micro-update you will see a message on your screen but no content refresh will take place. This way we avoid interrupting editors from their work.

Automatic updates in liveblogs are turned off if there have been no new micro-updates in the last 24 hours.

How does it work

TBD.

1.2b2 (2017-08-23)

• Avoid AttributeError on transform chain caused by invalid output on recent-updates view when there are no new micro-updates available (refs. plone.protect#64). [rodfersou]

1.2b1 (2016-06-21)

• Liveblogs are now added to the list of linkable objects in TinyMCE at installation time. [hvelarde]

• Fix URL of AJAX call to get latest updates of a Liveblog (fixes #32). [rodfersou]

• Liveblogs use now standard simple_publication_workflow; automatic updates in liveblogs are now turned off if there have been no new micro-updates in the last 24 hours; liveblog_workflow was removed (closes #31). [rodfersou]

• Use absolute paths to link to micro-updates. [hvelarde]

1.1b2 (2016-05-10)

• Micro-updates are now traversable; this allows to share them as separate pieces of content (closes #19). [rodfersou, hvelarde]

• Use POST as request method on form used to edit micro-updates. [hvelarde]

• A new text field to describe the Liveblog was added. [hvelarde]

• Remove dependency on five.grok (closes #5). [rodfersou]

• Package is now compatible with Plone 5.0 and Plone 5.1. [hvelarde]

1.1b1 (2016-04-19)

• Update view now uses batch pagination every 20 micro-updates to reduce load time for users with Editor role (closes #10). [hvelarde]

• Depend on plone.batching; this drops support for Plone 4.2. [hvelarde]

• Use POST as request method on form used to add micro-updates. [hvelarde]

• Remove referenceable extra; Archetypes is no longer the default framework in Plone 5. Under Plone < 5.0 you should now explicitly add plone.app.referenceablebehavior to the eggs part of your buildout configuration. [hvelarde]

• The dates of micro-updates older than today were not shown in liveblogs on private and inactive states (fixes #14). [hvelarde]

1.0b3 (2014-09-20)

• Rendering of plone.abovecontenttitle and plone.belowcontenttitle viewlets was removed from the update view. [hvelarde]

• Add styles for responsive (closes #7). [agnogueira]

• Bylines on micro-updates now honor security settings and will be displayed to anonymous users only if they are allowed to see this information (closes #6). [hvelarde]

• Editors can now edit micro-updates; a full refresh of the view will be scheduled after editing a micro-update to avoid displaying invalid content (closes #3). [hvelarde]

1.0b2 (2014-09-13)

• An adapter listing the URLs to be purged when a Liveblog is modified was added. [ericof]

• Refactor recent-updates view to get rid of the timestamp parameter. This way we avoid a potential source of DoS attacks. [hvelarde]

1.0b1 (2014-09-05)

• Timestamp handling was simplified. [hvelarde]

• Implement the Expires header on recent-updates view. This will help us control better how long the page is going to live. [hvelarde]

• Add a workflow specific to liveblogs. The workflow defines 3 states: private, active and inactive. This way we can control when automatic refresh of micro-updates happens. [hvelarde]

• Refresh the whole view when a micro-update has been deleted to avoid displaying invalid content. [hvelarde]

• The header viewlet was including the html and body tags on rendering. [hvelarde]

• Lack of id attribute on field text was preventing TinyMCE editor from loading on Plone 4.2. [hvelarde]

• Fire ObjectModifiedEvent event on micro-updates deletion to invalidate caching on views. [hvelarde]

• Implement handling of If-Modified-Since request header on recent-updates view. [hvelarde]

• Markup of time tag used on automatic updates was fixed. [hvelarde]

1.0a1 (2014-09-01)
