Rails 4.0.0.beta1で使わない方がよさそうなDBのカラム名

> [【Rails3】カラム名に使ってはいけない予約語を調べる - ふわふわRuby on Rails](http://d.hatena.ne.jp/zucay/20110120/1295490314)

を参考にして、空のモデルを作ってメソッド名を書きだす

```hoge.rb
class Hoge < ActiveRecord::Base
end
```

```
% rails c
Loading development environment (Rails 4.0.0.beta1)

> hoge = Hoge.new
=> #<Hoge id: nil, created_at: nil, updated_at: nil>

> open('methods.txt', 'w'){ |file|
>   file.print(hoge.methods.join("\n"))
> }
=> nil
```

# 雑感
- rails4では`type`は使っても大丈夫そう。
- `quoted_id`知らなかった。文字通り`"1"`とか`"NULL"`とか`"`で括られたidが返ってくる
