Question

Why isn't the composite_primary_keys gem for Rails working?

Answer 1

+1 A:

Did you add require 'composite_primary_keys' to the bottom of your environment.rb file as described here?

Okay, this clearly is the problem. Thanks. I'm still a bit new to Rails. I'm getting some errors when requiring this, but I'll figure it out and mark this as the answer if it solves the problem I described.

What kind of errors are you getting now?

http://stackoverflow.com/questions/2389129/why-am-i-getting-an-error-when-requiring-this-gem-in-environment-rb I think my rails install is jacked up or something. I'll try to fix this and let you know what happens.

Now I get this when running script/server: Library/Ruby/Site/1.8/rubygems.rb:220:in `activate': undefined method `map' for nil:NilClass (NoMethodError)

Okay, I fixed this by reverting and patching in changes. Yay. Now I get this with the require /Library/Ruby/Site/1.8/rubygems.rb:220:in `activate': You have a nil object when you didn't expect it! (NoMethodError) (AFTER end) and /Library/Ruby/Site/1.8/rubygems.rb:220:in `activate': undefined method `map' for nil:NilClass (NoMethodError) (BEFORE end).

YAY! I got it working! I had two versions of rake installed, so I uninstalled both, installed 1.1.0, reinstalled rails, and the require call in environment.rb works now! YAY!

Chad Johnson 2010-03-05 20:08:23

Very glad to hear that it worked. That is definitely a specific issue that I would not have been able to figure out through SO. Good job :)
