Greetings. Apologies if I missed something like this in the archives or
internet, but I''m having namespace issues using Ferret with Rails, but
this looks to be an issue with any library and Rails. Specifically, I have a
model class "Weight" in my application and Ferret also has a class
"Weight" in it (Ferret::Search::Weight). My app runs perfectly fine
until it first executes "require ''ferret''". At that
point, my definition of the class "Weight" disappears and I get
"uninitialized constant Weight" errors. I went through my Ferret gem
and changed the Ferret::Search::Weight class to Ferret::Search::FWeight, and all
works now.
Has anyone else come across an issue of a library trampling namespace? I have
tried putting the indexing code in a number of places within my app, and
"load"ing Ferret rather then "require"ing it, but loading
tends to fail to load Ferret.
It seems that Rails is taking the application namespace, and applying it within
all of the libraries. I believe this because after changing
Ferret::Search::Weight to Ferret::Search::FWeight, there still is a
Ferret::Search::Weight class, but it matches my model Weight < ActiveRecord
class, and there are Weight classes that match mine in all areas of the Ferret
library:
irb> Ferret::Search::FWeight
=> Ferret::Search::FWeight
irb> Ferret::Search::Weight
=> Weight
irb> Ferret::Search::Weight == Weight
=> true
irb> Ferret::Weight == Weight
=> true
irb> Ferret::Utils::Weight == Weight
=> true
irb> Ferret::Utils::Weight == Ferret::Search::FWeight
=> false
Thanks for any insight. I am a Ruby and Rails nuby and am using Win32
(temporarilly), Ruby 1.8.2, Ferret 0.3.2, and Rails 1.0.0.
