This plugin has become indispensable to me. The mass data import with MySQL's ON DUPLICATE KEY UPDATE syntax has hit a huge sweet spot in performance/maintainability for me. Also, the extensions to Rails 1.2 hash conditions (ie. field suffixes like gt contains starts_with and like) make it possible to do a lot of tricky condition merges that would only be possible using with_scope if I was still using traditional rails conditions in array form. Zach has also been tremendously responsive to feedback and future ideas. I encourage everyone to get behind this project. Some of it should definitely be in core.

This is so good that it really should be merged with rails itself...

I just want to use "to_csv" using "ar-extensions," but I have not been successful so far. What I did was:
1. gem install 'ar-extension'
2. ruby script/console
3. require 'ar-extensions'
4. a = User.find :first
5. a.to_csv
NoMethodError: undefined method `to_csv' for #<User:0x48bb86c>
```
    from c:/ruby/lib/ruby/gems/1.8/gems/activerecord-1.15.5/lib/active_record/base.rb:1863:in `method_missing'
    from (irb):19
    from :0
```
What should I do?
