Bye-bye, Observers


No more observers in Rails 4, farewell, never been much of a fan anyway.

However, one of my gems is enabling model attributes for use with a
client-side WYSIWYM editor. The sanitized markup ends up in the database
and has to be processed before shown in a view. The corresponding helper
does fragment caching. This cache has to be zapped when the model is
modified or deleted. And since the gem is generic, an observer for
“after_update” “after_destroy” seemed the obvious choice for this.

What would be the Rails 4 state of the art approach do do this without
using observers? Inject the above callbacks into the model directly?


Observers will be removed from rails 4, but will be possible use them
