Hi,

I have the simplest rails app:

my only controller says:

class MaxmindController \< ApplicationController  
@ip = request  
end

my index.rhtml in the views/maxmind folder says:

\<%= debug @ip %\>

the result of trying to view this in firefox is:

NameError in MaxmindController#index

undefined local variable or method `request’ for  
MaxmindController:Class

if I remove the one line from my controller and change my view code  
to:

\<%= debug request %\>

then i get my request object nicely displayed.

Why is request available only in the view and not in the controller?  
I’m running this locally under locomotive.

Thanks,

Gabor

Because you’re out of scope. @ip = request is in the class scope, and  
request is not available there.

Try using a before\_filter.

class MaxmindController \< ApplicationController  
before\_filter :get\_ip

protected  
def get\_ip  
@ip = request.remote\_ip  
end

end
