Model tries to use different table name in production than in development

I have a model called User. I have pluralize_table_names set to false so the table User uses is user. (That's kind of a mouthful!)

Interestingly, my model behaves correctly in development but in production User tries to use a table called users which doesn't exist. All my other models use their singular table names. Look at this:

$ rails console
Loading development environment (Rails 3.0.3)
irb(main):001:0> Client.table_name
=> "client"
irb(main):002:0> Appointment.table_name
=> "appointment"
irb(main):003:0> User.table_name
=> "user"
irb(main):004:0> 
$ rails console production
Loading production environment (Rails 3.0.3)
irb(main):001:0>开发者_如何学C Client.table_name
=> "client"
irb(main):002:0> Appointment.table_name
=> "appointment"
irb(main):003:0> User.table_name
=> "users"
irb(main):004:0>

As you can see, everything's fine except User in production. What gives?

Edit: here's the model code in production:

class User < ActiveRecord::Base
  acts_as_authentic
end

And in development:

class User < ActiveRecord::Base
  acts_as_authentic
end

Same exact thing. I even pointed my production instance at the same database as development and the problem persists. I started having these problems when I started using Authlogic, so I'm starting to suspect that the development environment somehow knows about some Authlogic stuff that the production environment doesn't.

Update: I tried to kill as many moving parts as possible. I set both my production environment and my development environment to point at the dev database. That didn't change anything. I changed my production environment to be a dev one and it started working. I changed my dev environment to a production one and it stopped working. This tells me there's something about the change from dev to production that makes it stop working. I have no idea what, though.

I figured it out. I ended up keeping the singular user table name in the database, but in my model, I did this:

class User < ActiveRecord::Base
  set_table_name "user"
  acts_as_authentic
end

The directives have to be in that order or else it will not work! I don't know why that's the case (actually, if I think about it a little bit, it makes sense) and I don't know why I decided to try to switch the order but I'm glad I did.
