How to make a link to bulk change columns in rails?

Question

Ruby on Rails

Hello everyone, there are notifications for users

<div class="notification">
  <h4>Уведомления</h4>
<% @activities.each do |activity| %>
    <ul>
    	<li>
    <%= render "activities/#{activity.trackable_type.underscore}/#{activity.action}", activity: activity %>
    	</li>
    </ul>
<% end %>
<%= link_to "отменить всё как прочитано"%>
</div>

It is necessary that when you click on "cancel everything as read", the read columns from false to true in the Activity base go to the database, please tell me how to do this?

Answer 1

1. we collect all id of these events into one array, for example activities[]
2. we send it via ajax serialize
3. we get this array in the controller

activities = Activity.find(params[:activities])
activities.each do |activity|
  activity.mark_as_read!
end
