And then how can use the id in my methode?

I'am sorry I have forgotten some code :
in the controller : @defautrec= Defaut.all

In the view
<% @defautrec.each do |n| %>
<tr>
<td><%= n.nomdefaut.nom_defaut%></td>
<td><%= n.repere%></td>
<td><%= link_to controller: "pages", action: "ajouter" do%><button,
class="btn btn-mini btn-success">Ajouter</button><%end%>
</td>
</tr>
<% end %>

I want a button which call a methode in my controller so I think your
right I should replace link_to by button_to.
