Localization plugin function in viewer issue

Hello, dudes:     My app utilises "Localization" plugin, and in the view, I added a link as follow: <%= link_to _ 'Sign up', :controller => 'account', :action => 'signup' %>

    _ 'Sign up' , this part, it does translate the words "sign up" into what I want, but the link function works incorrectly, if I check the source, it is "<a href="/tasks">注册</a> ", it should be like <a href="/account/signup">注册</a>, seems like the options "controller" & "action" didnt works in link_to ??

    Anybody knows what to do?

Thanks! Myst

Hi, I solved this , using _('Sign up'), rather than _ 'Sign up'
