Real-time Comments and Voting
:
Why re-render the entire comment template? The code can be simplified
Partial comment
#app/views/comments/_comment.html.erb
<%= content_tag :div, id: dom_id(comment), class: "card mb-3" do %>
<div class="card-body">
<h5 class="card-title"><%= comment.user.email %> said:</h5>
<p class="card-text"><%= comment.content %></p>
<p id='<%= dom_id(comment)%>_count'>
<%= comment.vote_count %>
</p>
<%= link_to "Up Vote", comment_votes_path(comment, choice: :up_vote, format: :turbo_stream), class: "card-link" %>
<%= link_to "Down Vote", comment_votes_path(comment, choice: :down_vote, format: :turbo_stream), class: "card-link" %>
</div>
<% end %>model Vote
# app/models/vote.rb
after_update_commit do
broadcast_update_to("comments", target: "#{dom_id(comment)}_count", html: comment.vote_count)
end
