配置rails使用中文

before_filter :configure_charsets

def configure_charsets
@response.headers["Content-Type"] ="text/html; charset=utf-8"
# Set connection charset. MySQL 4.0 doesn’t support this so it
# will throw an error, MySQL 4.1 needs this
suppress(ActiveRecord::StatementInvalid) do
ActiveRecord::Base.connection.execute 'SET NAMES UTF8'
end
end

将以上内容添加到Application.rb中即可。
