Listing comentarios
<% @comentarios.each do |comentario| %>
<=its says true for all, so the restaurant is nill but comentario.idresaturant show the correct value<td><%= link_to 'Show', comentario %></td>
<td><%= link_to 'Edit', edit_comentario_path(comentario) %></td>
<td><%= link_to 'Destroy', comentario, :confirm => 'Are you
sure?', :method => :delete %>
<% end %>| Restaurant | ||||||
|---|---|---|---|---|---|---|
| <%= comentario.comentario_%> | <%= comentario.estrellas %> | <%= comentario.usuario %> | <%= comentario.restaurant %> | <%= comentario.idrestaurant %> | <%= Comentario.reflections.keys %> | <%= comentario.restaurant.nill? %> |
<%= link_to ‘New Comentario’, new_comentario_path %>
here is the code http://pastie.org/1524215 well formated. the question
is that comentario.restaurant is nill, but its ok
comentario.idrestaurant cause it has the right value. what im doing
wrong? its suppose if i make @comentarios = Comentario.all, each
element in @comentarios has to be a instance of restaurant not?
