I resolved that problem.
I done somethig like so to update each column:
def update_multiple
@postis = Posti.find(params[:posti_ids])
@postis.each do |posti|
posti.update_column(:stato, params[:posti])
end
redirect_to prenotazione_path(params[:spectacle_id])
end
<%= form_for :posti, :url => update_multiple_path, :html => { :method =>
:put } do |f| %>
<%= hidden_field_tag "spectacle_id", params[:spectacle_id] %>
<strong>Posti scelti:</strong>
<ul>
<% for posti in @postis %>
<li>
<%=h posti.numero %>
<%= hidden_field_tag "posti_ids[]", posti.id %>
</li>
<% end %>
</ul>
<p>
<%= f.hidden_field :stato, :value => "checked" %>
</p>
<p><%= f.submit "PRENOTA" %></p>
<% end %>
It works very well and i am so very happy. Thank you Colin for helps. I
will very well a tutorial when i will finish all my esams at university.
Ruby on Rails is the best :)
