Ruby TinyInt（1）？

Question

我有一個用狀態標誌（這是一個tinyint（1））定義的mysql表。 但是，當我嘗試檢查值是真還是假時，我似乎得出了錯誤的結果。也就是說，它不會看到該值作爲一個合法的真或價值，而是測試的，如果它不是「無」或類似的 - 因此我的「似乎沒有工作」

results.each_hash do |row| 
# What I tried 

# (a) 
if row['status'] 
    # do something - doesn't seem to work 
end 

# (b) 
if row['status'].to_i == 1 
    # this seems correct 
end 

# (c) 
if row['status'] == false 
    # doesn't seem to work 
end 
end 

什麼是正確的方法檢查這個值（tinyint（1）），因爲它應該是Ruby中的TrueClass或FalseClass;然而（c）本身不起作用。

這是我所使用的參考 - 我假定這應該在導軌和紅寶石本身適用（除非ActiveRecord的做的工作） - http://www.orthogonalthought.com/blog/index.php/2007/06/mysql-and-ruby-on-rails-datatypes/

從active_record-3.2.13，abstract_mysql_adapter.rb代碼行96：

# By default, the MysqlAdapter will consider all columns of type <tt>tinyint(1)</tt> 
    # as boolean. If you wish to disable this emulation (which was the default 
    # behavior in versions 0.13.1 and earlier) you can add the following line 
    # to your application.rb file: 
    # 
    # ActiveRecord::ConnectionAdapters::Mysql[2]Adapter.emulate_booleans = false
