  gonzalezarthur Why does the model name Tueet (class Tueet < ApplicationRecord) have the file name tweet.rb (# models/tweet.rb)?

Some refactoring

class VotesController < ApplicationController
  ...
  def show
    @comment = Comment.find(params[:comment_id])
    @vote = Vote.find_or_create_by(user: current_user, comment: @comment)

    @vote.voted(params[:choice])
  end

class Vote < ApplicationRecord
  ...
  def voted(choice)
    return unless choice.in?(Vote::choices.keys)

    case choice
    when 'up_vote'
      up_vote? ? cancel! : up_vote!
    when 'down_vote'
      down_vote? ? cancel! : down_vote!
    end
  end

Fixed

• bugs in the Votes model (has_many :votes, dependent: :destroy move to User model ).

Added new feature:

• The title of the vote button changes depending on user actions: up_vote(down_vote) -> undo_vote -> up_vote(down_vote). Title change usually only for current users (Stimulus controller);
• Unauthenticated users cannot vote on a comment (Stimulus controller );
• The user who voted will receive a flash message with information;
• Added the ability for the author of a comment to delete it (Stimulus controller);
• Hotwire flash messages (lTailwind style);
• Autohide and manual closing of Hotwire flash messages (Bootstrap JS and Stimulus controller);
• Comments counter that changes dynamically after adding/removing objects (broadcasts html).
• Counter votes, rewritten only on broadcasts HTML parts;
• Small refactoring code
