Same here.... I'm not sure on why... but there are a lot of unanswered
Anyway. About your question.
If you have the "has_many" relationship in place, you can access the
collection of associated objects, as simple as this:
@collection = object.child_object
In theory, you can even use paginate... but I hasn't done that.. I just
In the controller:
@persona = Persona.find(params[:id], :include => [:contribuyentes])
@contribuyentes_asoc = @persona.contribuyentes.find(:all,:order =>
redirect_to :action => 'index'
And in the view:
<table celpadding="5" cellspacing="0">
<% par_impar = 1
for contribuyente in @contribuyentes_asoc
par_impar = 1 - par_impar %>
<tr valign="top" class="ListLine<%= par_impar %>">
<td><%= h contribuyente.nombre %></td>
<td><%= h contribuyente.rif %></td>
<td class="ListActions"><%= link_to 'Ver detalles', :controller =>
'contribuyentes', :action => 'mostrar', :id => contribuyente %></td>
<% end %>
