I've installed ancestry with bundler on a rails 2.3.8 project and I get NameError: undefined local variable or method `has_ancestry' for #Class:0x007f90d3ba2398 Any ideas on why that might happen ?
I assume you have got this working by now. I hit this same error using bundler and rails 3.2.2 . I restarted my server and the error went away...
I do have it working but I don't remember what the solution was... thanks tho
