Can I get the name of the current controller in the view

Question

Is there a way to figure out what the current controller is from within the view   For an example of why I would want to know this  if several controllers share the same layout  I may have a part in the layout ERB file where I want to highlight the current page s menu item based on the controller   Maybe that is a bad approach  If so  what is the more preferred way to do this   I m interested to know about getting the name of the current controller either way  though    Obviously I could put something like  controller name    users  in each controller  but that seems like the sort of thing Rails would ve already done behind the scenes  So I m just wondering if there s a built-in way

Use controller controller name In the Rails Guides  it says   The params hash will always contain the  controller and  action keys  but you should use the methods controller name and action name instead to access these values  ActionController Parameters So let s say you have a CSS class active   that should be inserted in any link whose page is currently open  maybe so that you can style differently    If you have a static pages controller with an about action  you can then highlight the link like so in your view   lt li gt     lt a class  button  lt   if controller controller name     quot static pages quot   amp  amp  controller action name     quot about quot    gt active lt  end  gt   href  quot  about quot  gt        About Us    lt  a gt   lt  li gt
