- Defined in:
Folder model. Each instance of this class represents a single folder to which a user can add feeds.
Each folder belongs to a single user, and each user can have many folders (one-to-many relationship).
Each folder can be associated with many feeds, and each feed can be associated with many folders as long as they belong to different users (many-to-many relationship, through the feed_folders table). However a feed can be associated with at most one folder belonging to a single user.
A relationship is also established between Folder and Entry models, through the Feed model. This enables us to retrieve all entries for all feeds inside a folder.
The title field is mandatory. As it is introduced by the user, it is sanitized before saving in the database.
A given user cannot have two folders with the same title. Folders with the same title are allowed as long as they belong to different users.
The subscriptions_updated_at attribute is the date/time at which a feed in the folder was last changed. Events that update this attribute are:
- unsubscribing from a feed in the folder - changing the unread entries count for a feed in the folder - changing the title of a feed in the folder - changing the URL of a feed in the folder - moving a feed into or out of the folder
