AAJ does not create journals, when models are created using sub classes (Bug #708)

Remote issue URL: Affected version:2.4.0


In chiliproject_backlogs, we are using custom subclasses of the Issue model. The subclasses contain some custom behavior, that is used in the plugin's code. This way we do not need to add them to the global Issue model. Also, we can have different behavior for Stories, Tasks and Impediments.

This worked fine, when using Chili 1.x. With the introduction of acts_as_journalized, we were running into a problem. AAJ derives the Journal class' name from the instance's class name. This will not work correctly, when dealing with the instances of subclasses.

The code within the pull request, that will be attached, changes AAJ, so that only models, with direct calls to acts_as_journalized have Journal classes. All subclasses, that do not call acts_as_journalized directly, will use their parent class' one.

[#708] Using instance var to store journal class name

this way journal classes are only created for classes with
calls to acts_as_journalized. You may now subclass journaled models to extend them with helper methods in plugins w/o interfering with aaj.

Bug #708: AAJ does not create journals, when models are created using sub classes


Updated by Gregor Schmidt at 2011-11-17 09:52 am

The bug results in an error message printed to standard out and the journal will silently not be created. This is handled by L134 in aaj/lib/redmine/acts/journalized/creation.rb

We would love to see this in the core, since only then people could start using chiliproject_backlogs without the need to patch the core.

This looks good to me, staged for 2.6.0, but I'd like to give Eric and Holger the chance to have a look before merging it.

Merged in ba0ded8, I'll wait for the CI to test it through to close here.
