Plugins » Katello

Katello 3.7.1, unable to load any Katello-related pages.

With stbenjam's help, we were able to determine it was related to the fact that in 3.5 I removed the abrt plugin (it was preventing the server from starting).

# foreman-rake console
> Setting.where(type: 'Setting::Abrt').all
ActiveRecord::SubclassNotFound: The single-table inheritance mechanism failed to locate the subclass: 'Setting::Abrt'. This error is raised because the column 'category' is reserved for storing the class in case of inheritance. Please rename this column if you didn't intend it to be used for storing the inheritance class or overwrite Setting.inheritance_column to use another column for that information.

This prevented all plugins from being able to load their respective settings.rb files.

There were no errors anywhere about the failed transactions.

Manual fix:

# foreman-rake console
> class Setting::Abrt < Setting; end; Setting.where(category: 'Setting::Abrt').destroy_all

Original issue¶

I noticed this when I was unable to load any Katello-related pages due to a JS console error:
