I have this form:
<%= simple_form_for(@student) do |f| %>
<%= f.input :first_name, label: "Nombre" %>
<%= f.input :hours_studying, as: :select, collection: [1, 2],
prompt: 'Horas' %>
<%= f.input :library_id, as: :select, collection: @libraries %>
<div class="text-center">
<%= f.button :submit, "Regístrame!", class: "btn button rounded-pill
p-3 my-4 fs-18 shadow" %>
</div>
<% end %>
Libraries have a country and a city, how could I add two fields to the form to check the country and the city and filter the libraries accordingly?
