namespaces - rails nested object form and namespaced controller -

i have nested object this:

class work < activerecord::base   belongs_to :issue   belongs_to :author   has_many :pages, :class_name => 'work'   accepts_nested_attributes_for :pages, :allow_destroy => true end  class page < activerecord::base   belongs_to :work end 

and have form create/edit work, fields nested page object. followed this post setting things up, i'm using helper form creates new page when start out.

module adminhelper    def make_work(work)     returning(work) |w|       w.pages.build if w.pages.empty?     end   end  end 

then, in form partial have:

- form_for make_work(@work) |f|   ...   - f.fields_for :page |page_f|     = page_f.label :text     %br     = page_f.text_area :text    %p     = f.submit "submit" 

that displays fields page, when it's submitted looks create action in works controller. create action in admin works controller (namespaced), breaks.

i try namespaced object, if way doesn't know pages:

- form_for make_work([:admin, @work]) |f|   ... 

how use namespace nested object form has pages method, posts namespaced admin/works controller?

i think should have:

fields_for :pages |page_f|                 ^ 

also check in generated html if submit path form correct. in case should like:

/admin/works/3 

edit:

example fields_for:

<% form_for @person |person_f| %>   <% person_f.fields_for :emails |email_f| %>      <%= email_f.text_field :address %>   <% end %> <% end %> 

and relationship like:

class person   has_many :emails end 

make sure didn't iterate on pages this:

<% @work.pages.each |page| %> ...   <% fields_for :page |p| %> ...
