Ruby TinyInt（1）？

Question

我有一个用状态标志（这是一个tinyint（1））定义的mysql表。 但是，当我尝试检查值是真还是假时，我似乎得出了错误的结果。也就是说，它不会看到该值作为一个合法的真或价值，而是测试的，如果它不是“无”或类似的 - 因此我的“似乎没有工作”

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 

什么是正确的方法检查这个值（tinyint（1）），因为它应该是Ruby中的TrueClass或FalseClass;然而（c）本身不起作用。

这是我所使用的参考 - 我假定这应该在导轨和红宝石本身适用（除非ActiveRecord的做的工作） - http://www.orthogonalthought.com/blog/index.php/2007/06/mysql-and-ruby-on-rails-datatypes/

从active_record-3.2.13，abstract_mysql_adapter.rb代码行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
