    To display the errors in your view, you must look for any errors that have been generated in the object (eg @reunion) and, if so, display them in your view.

    For example, in your view new.html.erbyou could add the following code 1 :

    <% if @reunion.errors.any? %>
  <div>
    Se han encontrado los siguientes errores:
    <ul>
      <% @reunion.errors.full_messages.each do |message| %>
        <li><%= message %></li>
      <% end %>
    </ul>
  </div>
<% end %>

    You must define the place on the page where you want this message to be displayed (usually it is at the top of the form) and style it according to the design of your site.

    1 I'm assuming the object you want to create is called @reunion, but substitute the variable for whatever is defined in the createcontroller action.
