Hello,  
I am using RJS and Edge Rails and I was wondering if the page object  
should  
be available in helpers also.

For example if I have a helper function

def update\_flash\_messages  
page.replace\_html ‘flash\_messages’, (show\_flash\_messages :textilize  
=\> true)  
page.visual\_effect ‘flash\_messages’, :appear  
end

and then in my RJS files I call  
update\_flash\_messages

But right now the above code _doesn’t work_, rather I have to pass the  
page  
object as shown below:

def update\_flash\_messages(page)  
page.replace\_html ‘flash\_messages’, (show\_flash\_messages :textilize  
=\> true)  
page.visual\_effect ‘flash\_messages’, :appear  
end

and RJS file  
update\_flash\_messages page

Notice the passing of `page’ object. Will it not be convenient if Rails  
does  
it automatically.  
Or am I missing something?

## Thanks.

Sure can, on the latest code in trunk, but you have to call them on  
the page object:

class RjsController  
def rjs  
render :update do |page|  
page.update\_flash\_messages  
end  
end  
end

module RjsHelper  
def update\_flash\_messages  
page.replace\_html ‘flash\_messages’, (show\_flash\_messages :textilize  
=\> true)  
page.visual\_effect ‘flash\_messages’, :appear  
end  
end
