    copied!<p>I've posted a question relating to this before but it was unclear. I've simplified the code so I can copy it here and have it be as straightforward as possible. I'm still not sure what the best way to debug this may be but here it goes:</p> <p>My 'new' action (could be any really) for a resource (again, can be any):</p> <pre><code>def new RDF::RDFa::Reader.open("http://www.tripadvisor.com/Hotel_Review-g186525-d280839-Reviews-Gerald_s_Place-Edinburgh_Scotland.html") do |r| r.each_statement do |statement| Rails.logger.debug(statement) end end respond_to do |format| format.html { }# new.html.haml format.json { render json: @base_item } format.js end end </code></pre> <p>The page renders fine and the RDF code is run successfully, however, when I refresh the page or try to access anything else, I get the following (substitude 'base_item' with whatever resource I'm trying to access, they all fail with this error):</p> <pre><code>ActionController::RoutingError (private method `redefine_method' called for #&lt;Class:0x000001058527c0&gt;): app/models/base_item.rb:3:in `&lt;class:BaseItem&gt;' app/models/base_item.rb:2:in `&lt;top (required)&gt;' app/controllers/base_items_controller.rb:3:in `&lt;top (required)&gt;' </code></pre> <p>I'm wondering if this is something specific to the rdf gem (which uses nokogiri) or if it is a general routing issue but haven't found a way to test that.</p> <p>Any help appreciated.</p> <p>EDIT: It seems it has to do with the r.each_statement line as if I take that out, things keep working..</p> <p>UPDATE: I haven't been able to reproduce this outside of Rails but I've narrowed it down to an issue with ActiveRecord. I've set up a sample app at <a href="https://github.com/slamorsi/rdfTest" rel="nofollow">https://github.com/slamorsi/rdfTest</a></p> <p>There are two models, Test and TestChild. The error is reproducible if Test and TestChild are related - right now Test has a has_many relationship with TestChild. The root of the app goes to test#index which has sample RDF/RDFa code. If you load the page once then refresh, you'll see the 'redefine method called...' error. If there's no relationship between the models or if no RDF/RDFa statements.each code is executed, everything works fine. I don't know what could possibly cause this.</p>
