在app文件中的application.rb 文件中增加过滤方法，
before_filter :configure_charsets
def configure_charsets
# @headers["Content-Type"] = "text/html; charset=utf-8"
@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
