Image Positioning about attachinary HOT 3 OPEN

Use a singular model. A User has_many :photos and a Photo has_attachment :file. Then you can add whatever metadata on Photo you want.

Just make sure you do efficient database calls so you aren't doing N+1 and you should be fine.

In this commit we made it a permanent part of the plugin. We believe photo ordering is a fundamental part of a photo plugin and don't want to have an additional join for something that can be done in a column:

@maletor How do I prevent N+1s?

I tried Posting.includes(:user, :photos), but get the following error:

Association named 'photos' was not found on Posting; perhaps you misspelled it?

Is the association named something else under the hood?

More:

>> Posting.first.photos
=> #<ActiveRecord::Associations::CollectionProxy []>
>> Posting.includes(:photos).first.photos
!! #<ActiveRecord::AssociationNotFoundError: Association named 'photos' was not found on Posting; perhaps you misspelled it?>
