i am getting the following error message using the AAF gem version 0.4.4 in my rails app. undefined method `ferret\_rank=’ for #Page:0x246060c i"m using multi search but i have the same code working on another app, using the plugin. To me this method looks like it’s missing from the gem version, but is that possible? I have an index compiled, but this error appears whenever i search for something in the index. when i search for terms not in the index, it works as expected,… nothing is returned.

i am not using multi search, i meant to write i am using a shared index, but it only had ONE model in it for now. although that still doesn’t seem to make a difference. sorry for the confusion. ---

Did you manage to solve this issue. I have exactly the same error using the shared index in config/aaf.rb In the console I rebuilt the indexes for the relevant 3 models I am using. I do an example search in the console: results = ActsAsFerret.find(“pete\*”, ‘shared’) I get results back perfectly. When I do it in the application I get undefined method `ferret_rank=' for <2nd model in my list> /usr/local/lib/ruby/gems/1.8/gems/activerecord-2.3.4/lib/active_record/attribute_methods.rb:255:in`method\_missing’ /usr/local/lib/ruby/gems/1.8/gems/acts\_as\_ferret-0.4.4/lib/acts\_as\_ferret.rb:474:in `retrieve_records' /usr/local/lib/ruby/gems/1.8/gems/acts_as_ferret-0.4.4/lib/acts_as_ferret.rb:473:in`each’ /usr/local/lib/ruby/gems/1.8/gems/acts\_as\_ferret-0.4.4/lib/acts\_as\_ferret.rb:473:in `retrieve_records' /usr/local/lib/ruby/gems/1.8/gems/acts_as_ferret-0.4.4/lib/acts_as_ferret.rb:452:in`each’ /usr/local/lib/ruby/gems/1.8/gems/acts\_as\_ferret-0.4.4/lib/acts\_as\_ferret.rb:452:in `retrieve_records' /usr/local/lib/ruby/gems/1.8/gems/acts_as_ferret-0.4.4/lib/ferret_find_methods.rb:43:in`ar\_find’ /usr/local/lib/ruby/gems/1.8/gems/acts\_as\_ferret-0.4.4/lib/ferret\_find\_methods.rb:12:in `find_records' /usr/local/lib/ruby/gems/1.8/gems/acts_as_ferret-0.4.4/lib/acts_as_ferret.rb:343:in`find’ Can anyone help I am banging my head against a wall 🙂 Thanks in advance. ---

I spoke to Jens who was on vacation - thanks a lot mate, really appreciate your help. It appears that this happens when the model is not extended properly. Solutions: – Use the plugin rather than the gem. This fixed it for more straight away. – require config/aaf.rb in your environment.rb Hope this helps some one. ---

> 472 # set scores and rank 473 tmp\_result.each do |record| 474 record.ferret\_rank, record.ferret\_score = id\_array[record.id.to\_s] 475 end is where it breaks.
