Missing Block

[nhocki]

Hello, I get a Missing Block error when I try to use nested_form_for instead of form_for

<% nested_form_for @project, :html => { :multipart => true } do |f| %>

The most wired thing is that it happens when I try to submit something that is not valid and not when I first render the "new" action.

Ok, I "found" the problem but I have no idea how to solve it:

I have a select list inside my nested model. So the form has "f.select ..." but when I edit my object, it won't get selected in the one that it was stored. So I just added a
for c in competences
fields_for :competences, c do |builder|
render partial
end
end

And there is where the missing block error appears.

Any help?
Thanks

Just had to use the f.object method to get what I wanted...

Can you elaborate on your solution? I'm having the same problem.
Thanks.

Ok, what I have is this:
#_form.html.erb
<% f.fields_for :webToolUrls do |builder| %>
<%= render 'webToolUrl_fields', :f => builder %>
<% end %>

  #_webToolUrl_fields.html.erb
  <% field_set_tag "Herramienta  Web 2.0", :class => "formFieldSet" do %> <br/>
     # Some other fields here ...
     <%= f.select :webTool_id, options_from_collection_for_select(WebTool.all, :id, :name, f.object.webTool_id) %> <br />  # notice the f.object.webTool_id
  <% end %>

I hope that helps
