Problems with activerecord associations between tables

Hi all, i'm developing an application with 40 tables that they have relations between them, in my products_list when i render the results in my view everything worked fine but from one day i i get an error: NoMethodError in Admin/product#products_list

Showing app/views/admin/product/products_list.rhtml where line #35 raised:

undefined method `re_products_type' for #<ReproductsSubtype: 0xb731b624>

Extracted source (around line #35):

32: <% for item in @products %> 33: <tr class="listLine<%= cycle(1,0) %>"> 34: <td><%= item.id %></td> 35: <td><%= item.re_products_subtype.re_products_type.type_name %></

is strange because never happened since a month that i have started working on this application but if i restart apache everything is ok but after 5 minutes i get the same error again. I'm the only developer that work on this...this thing is driving me crazy. Any solutions or ideas please? thanks in advance and sorry about my english!

Does this only happen in development mode?

Yes i'm in development mode, i figured out doing as showen below>

ReProductsType.find_by_id(item.re_products_subtype.re_products_type_id).type_name but i prefer as before...

My models: class ReProductsSubtype < ActiveRecord::Base         belongs_to :re_products_type end

class ReProductsType < ActiveRecord::Base         has_one :re_products_subtype end

I can do an explicit sql query to have better performace, but i would like to understand whyt this happen! Thanks to all

I've seen some funkiness due to the autoloading stuff. major culprits include using require to require things that could be autoloaded
