I'm trying to find out whether a particular layout file exists at runtime. I need to potentially change the layout depending on which "site" a customer is visiting. I can do this by calling a method in the controller to determine the layout similar to:
def customer_layout
if @site_id.nil?
return "customer_standard"
else
return "customer_site_" + @site_id.to_s
end
end
I need to determine if a particular site does indeed have a custom layout, if not then fall back to the standard one. So I need to see if "customer_site_123.rhtml" actually exists in the layout directory. The problem is I don't want to hard code absolute paths that are certain to change on deployment.
Is there a way to determine what the current layout directory is so I can use that to try and find the file?
Eventually this will apply to css and image folders so any pointer there will help too.
Thanks,
Gary.
