Hi guys,

I need to translate the strftime into chinese.

I found a tutorial (ref:  
[Out of Computer: 讓Ruby on Rails顯示中文日期](http://out-of-pc.blogspot.com/2008/01/ruby-on-rails.html))  
`
require ‘date’
Date::ABBR_DAYNAMES.replace %w(日 一 二 三 四 五 六)
Date::DAYNAMES.replace %w(星期日 星期一 星期二 星期三 星期四 星期五 星期六)
Date::ABBR_MONTHNAMES.replace %w(nil 1月 2月 3月 4月 5月 6月 7月 8月 9月 10月 11月
12月)
Date::MONTHNAMES.replace %w(nil 一月 二月 三月 四月 五月 六月 七月 八月 九月 十月 十一月 十二月)
`

It asked us to update the environment.rb.

However, I found “replace can’t modify frozen array” error when I  
restart the server.

I don’t know whether this way to update the frozen array is correct? Is  
there any better solution?

My Rails is “2.0.2”.

Thanks much  
Arthur

well…

1.Date::ABBR\_DAYNAMES is a const var, you can do force-assignment:  
Date::ABBR\_DAYNAMES=%w[日 一 二 三 四 五 六]  
just ignore the warnings.

2.Date::ABBR\_DAYNAMES is a frezon object, you do some hacking to  
unfreeze  
it:

`

require ‘dl/struct’

module Internal
extend DL::Importable

typealias “VALUE”,nil,nil,nil,“unsigned long”
typealias “ID”,nil,nil,nil,“unsigned long”

Basic=[“long flags”,“VALUE klass”]
RBasic=struct Basic
RObject=struct(Basic+[“st_table *iv_tbl”])

FL_FREEZE=1<<10
end

class Object
def immediate?

```
[Fixnum,Symbol,NilClass,TrueClass,FalseClass].any?{ |klass| 

```

klass
===self}
19. end
20.
21. def unfreeze
22. return self if immediate?
23. Internal::RObject.new(DL::PtrData.new(self.object_id *
2)).flags&= ~
Internal::FL_FREEZE
24. self
25. end
26.
27. end
28.
29. Date::ABBR_DAYNAMES.unfreeze
30. Date::ABBR_DAYNAMES.replace…
`

But… I think it’s much easizer \*changing you local(set it to  
zh\_CN.utf-8)  
\*to make strftime return chinese.
