Here's the complete code in case anyone else arrives here with the
same problem.
No doubt hardened Rubyists will be able to tidy up my syntax, but this
is passing all my specs right now so I'm happy. :-)
# app/models/project.rb
acts_as_tree :order => "name"
# app/controllers/projects_controller.rb
def new
if params[:parent] == nil
@parent = 0
else
@parent = Project.find(params[:parent]).id
end
...
end
# app/views/projects/show.html.erb
<%= link_to("Create A Sub-Project",
{:controller=>"projects", :action=>"new", :parent => @project.id}) %>
# app/views/projects/new.html.erb
<% form_for(@project) do |f| %>
...
<%= f.hidden_field :parent_id, {:value => @parent} %>
...
<% end %>
