Method: Cms::Behaviors::Publishing::InstanceMethods#publish!

Defined in:
lib/cms/behaviors/publishing.rb

#publish! ⇒ Object

Force the publishing of this block.

Warning: The behavior of calling the following on an existing block:

block.save_on_publish = true
block.save!

Is different than calling:

block.publish!

And it probably shouldn’t be. Try to merge the ‘else’ with the ‘Versioning#create_or_update’ method to eliminate duplication.

In addition, after_publish is NOT called if you do:

block.save_on_publish = true
block.save!

which will cause problems if blocks are updated via the method (like with the UI)
