I have a model event.rb:

    class Event < ActiveRecord::Base
      serialize :data
      belongs_to :user
    end
    class ProductAddedEvent < Event; end
    class CollectionCreatedEvent < Event; end
    class FollowingEvent < Event; end
    class FollowedEvent < Event; end
    class CommentAddedEvent < Event; end

which seems to be causing Rails Admin (latest version as of today) to throw an error when I try to look at any model:
uninitialized constant CollectionCreatedEvent

Extracted Source:
1: <%
2: max_visible_tabs = RailsAdmin::Config::Sections::Navigation.max_visible_tabs
3: models = RailsAdmin::Config.visible_models.select { |model| authorized?(:list, model.abstract_model) }
4: %>

    Note that hiding the models in an initializer doesn't seem to help:
    RailsAdmin.config do |config|
    config.model Event::ProductAddedEvent do
    visible false
    end
    config.model Event::CollectionCreatedEvent do
    visible false
    end
    config.model Event::FollowingEvent do
    visible false
    end
    config.model Event::FollowedEvent do
    visible false
    end
    config.model Event::CommentAddedEvent do
    visible false
    end
    end

Any progress on this? I started seeing this outside of Rails Admin today. In a namespaced controller, with a namespaced model.

Removing the list and edit blocks from the rails_admin config in the parent model seemed to "fix" the issue for my part.

No problems if using the console to load the class and run code. It's just affected when running requests/code through the server.

Sorry if this ain't enough information or if it should be posted as a new issue, but if you need anything more I'll be happy to help :)

@mediavine reported a similar problem in issue #558.

@dustMason this occurs because you have put all child classes in event.rb.
When Rails was requested to load CollectionCreatedEvent class, it will look for 'collection_created_event.rb' in your app(and that doesn't exist so error happens).
Separating child class definitions as

  • app/model/event.rb
class Event < ActiveRecord::Base
  serialize :data
  belongs_to :user
end
  • app/model/collection_created_event.rb
class CollectionCreatedEvent < Event; end
  • app/model/comment_added_event.rb
class CommentAddedEvent < Event; end
  • and so on...

will solve your problem.

(tested with Rails3.0.7 and rails_admin(2b4573e))

Please reopen if #462 didn't fix it.
