🚀 AJAX Remote Form Submission​

Use Rails UJS or Fetch API to submit forms asynchronously, then render JSON or partials for seamless updates. Mark your form with remote: true and handle responses in .js.erb templates.

<!-- app/views/comments/_form.html.erb -->
<%= form_with(model: [ @post, @comment ], remote: true) do |f| %>
  <%= f.text_area :body %>
  <%= f.submit 'Post' %>
<% end %>
// app/views/comments/create.js.erb
<% if @comment.persisted? %>
  $("#comments").append("<%= j render @comment %>");
  $("#new_comment")[0].reset();
<% else %>
  $("#comment_errors").html("<%= j @comment.errors.full_messages.join(', ') %>");
<% end %>
