I’m trying to set up my RESTful controllers to allow public reading of  
data  
only when they are requesting XML. I’m using acts\_as\_authenticated for  
my  
authentication, and am basically trying to do something like this:

class MyController \< AC  
before\_filter :login\_required do |controller|  
true if controller.params[:format] == ‘xml’  
end

def index  
@models = Model.find(:all)

```
respond_to do |wants|
  wants.html { render :nothing => true }
  wants.js { render :partial => 'index' }
  wants.xml { render :xml => @models.to_xml }
end

```

end  
end

Should I just make the whole action public or is there a proper way of  
doing  
this?

Thanks

Jason
