设计抛出一个我不明白的问题。

使用更好的错误 gem；这是它被捕获的地方:

在 constantize(gem) activesupport-3.2.12/lib/active_support/inflector/methods.rb 中阻止

  225         names = camel_cased_word.split('::')
  226         names.shift if names.empty? || names.first.empty?
  227 
  228         constant = Object
  229         names.each do |name|
  230           constant = constant.const_defined?(name, false) ? 
                  constant.const_get(name) : constant.const_missing(name)
  231         end
  232         constant
  233       end
  234     end

Local Variables:
name      [17]
camel_cased_word [17]
names    [[17]]
constant Object

有任何想法吗？哪些进一步的信息会有用？

这是跟踪末尾的一大块:
