LoadError (Expected model.rb to define Model)

Rails
1

Hello,

I’m having an error that occurs in production (on Dreamhost) but does
not occur in development on my local machine. The situation is that
there is a model (Article), and it uses act_as_ferret for search. The
error is as follows (where I say {full server path}, that’s not what
the error says, just my note):

LoadError (Expected {full server path}/article.rb to define Article):

For this app, Rails is frozen at 2.0.2. All gems are included in /
vendor. Any help would be most appreciated. Thanks.

This is the unfortunately vague error you can get when rails auto
loads a file for you and an error occurs loading that file (eg that
file tries to oad a gem and fails).
You might be able to get a more sensible error if you required the
file article.rb explicitly.

Yeah,
I normally go into script/console

and just call the class name “Article”
is usually quite verbose

Hello,

I am having the same problem with acts_as_ferret, did you find a
solution?

Thanks,
