Algolia Search tagging based on Rails associations, how to update tags when association is created/destroyed?

I have a simple algolia setup with a few models and each model has a few attributes, ex:

class User < ActiveRecord::Base
  include AlgoliaSearch

  algoliasearch do
    attributes :id, :name

    add_attribute :_tags    
  end

  def _tags
    users = []

    self.connections.each do |connection|
      users.push('user_' + connection.user_id.to_s)      
    end

    users
  end
end

The setup above easily allows me to restrict search results on a per user basis so that the user only sees the records that they have permission to see if they are associated/related in the Rails app.

However, when the Connection model is created or destroyed, the User model is unaware and thus affects the search results negatively.

How can I add an ActiveRecord callback to the Connection model and update the _tags key on the record accordingly so that the _tags is updated to include or exclude (based on create or destroy)?

tldr: _tags on a record in Algolia has the value ['user_1', 'user_2'] determined by associations in Rails. The association between the record in Algolia and user_2 is removed from the DB in Rails, how can I remove user_2 from the array of tags on the record in Algolia?

There is a pending issue on GitHub about that: detecting changes in the underlying associations.

In the meantime, you could force the indexing of the User object in an after_save callback of the Connection object:

class User
  algoliasearch do 
  # [...]
  end
end


class Connection
  after_save :reindex_user
  belongs_to :user

  private
  def reindex_user
   self.user.reindex!
  end
end
