I18n is not working

[ericcong]

I edit the locale file as
http://guides.rubyonrails.org/i18n.html#translations-for-active-record-models
says, but table headers are still not translated

Can you try in your rails console something like this:

YourModel.human_attribute_name(:your_attribute)

and make sure what it translates correctly?

I tried in the console and it's working correctly, but in the view it doesn't.
I also double checked I18n.locale in the view, the locale is correct.
It's so weird.
