Instance Method Details

#following ⇒ Object

Public: Returns a collection with all the entities this user is following.

This can’t be done as with a ‘has_many :following, through: :following_follows` since it’s a polymorphic relation and Rails doesn’t know how to load it. With this implementation we only query the database once for each kind of following.

Returns an Array of Decidim::Followable
