Ok, I've followed this cast
http://railscasts.com/episodes/197-nested-model-form-part-2
but I get an error when I try to add the link to "add fields" (remove
works as expected) this is the error
NoMethodError in Projects#new
Showing /home/angelo/nestattr/app/views/projects/_form.html.erb
where line #24 raised:
undefined method `klass' for nil:NilClass
Extracted source (around line #24):
21: <%= render "task", :f => t %>
22: <% end %>
23: <p>
24: <%= link_to_add_fields "Add task", f, :task %>
25: </p>
26: <div class="actions">
27: <%= f.submit %>
Currently I'm using rails 3.0.9, so maybe something has changed since
then, please, tell me what's wrong
