broadcasts_to(stream, inserts_by: :append, target: broadcast_target_default, **rendering)

Configures the model to broadcast creates, updates, and destroys to a stream name derived at runtime by the stream symbol invocation. By default, the creates are appended to a dom id target name derived from the model’s plural name. The insertion can also be made to be a prepend by overwriting inserts_by and the target dom id overwritten by passing target. Examples:

class Message < ApplicationRecord
  belongs_to :board
  broadcasts_to :board
end

class Message < ApplicationRecord
  belongs_to :board
  broadcasts_to ->(message) { [ message.board, :messages ] }, inserts_by: :prepend, target: "board_messages"
end

class Message < ApplicationRecord
  belongs_to :board
  broadcasts_to ->(message) { [ message.board, :messages ] }, partial: "messages/custom_message"
end

Parameters

inserts_by key = :append
target key = broadcast_target_default
