Description

Introduced with r18780 Version.table_name is not available, if a gem package (like attr_encrypted) is used with a class named "Version".

At the moment this problem does not exist with Gem packages from Redmine itself, but gems from plugins.

Existing tests are broken, e.g.

bin/rails test test/unit/project_test.rb -n test_move_a_root_project_to_a_project
# Running:

E

Error:
ProjectTest#test_move_a_root_project_to_a_project:
NoMethodError: undefined method `table_name' for AttrEncrypted::Version:Module
    app/models/issue.rb:1739:in `update_versions'
    app/models/issue.rb:1385:in `update_versions_from_hierarchy_change'
    app/models/project.rb:935:in `update_versions_from_hierarchy_change'
    app/models/project.rb:424:in `set_parent!'
    test/unit/project_test.rb:316:in `test_move_a_root_project_to_a_project'

Similar problem was #23269. A better description of the problem with examples are here: https://stackoverflow.com/questions/21115567/autoloading-classes-using-class-self-in-rails

I added a patch for a more solid solution to prevent the problem. It would be great to have this change in Redmine.

I added another version of patch, which uses Rails 5 where.not and Arel::Table. With this solution, no more table name specification is required.

Both solutions work, but second one is more cleaner - but more refactoring.

I think the first variant should be preferred, see https://github.com/rails/rails/issues/36761
