Hi all, I have another problem that I fight with for some time and I could not understand where is the problem. Probably the problem is that I am quite “green” in RR 🙂 I am trying to make the Demo Application that comes with Ferret to work but I guess something with my environment is not OK. I will do apreciate any help.

Dimitar, it appears you added Acts\_as\_ferret to your environment.rb file. you shouldn’t need that if you are using the latest version. The gem/plugin does that kind of magic for you. get rid of it and see if it works. ---

Did you actually install the plugin to vendor/plugins/acts\_as\_ferret ? The demo app doesn’t run out of the box. I used to use svn:externals for this but since the move to git this step is necessary.

Hi, Yes, this was the problem. I have forgotten to install the plugin to the demo application. Do appreciate your help. Dimitar P.S Actually the application manage to start, but does not work … for now 🙂
