Hello All-

I’ve been using the memcache session store sucessfully since rails  
2.0, but after starting a new app with v 2.1 I’m getting the following  
error at each page request:

mem\_cache\_store.rb:54:in `initialize’

This is happening with both 2.1 and edge. Any pointers? Any updated  
howtos out there?

thanks

FYI, my memcache settings started as this

development:  
memcache\_options = {  
:compression =\> false,  
:debug =\> false,  
:namespace =\> “app-dcru-#{RAILS\_ENV}”,  
:readonly =\> false,  
:urlencode =\> false  
}  
memcache\_servers = [‘localhost:11211’]

config.action\_controller.fragment\_cache\_store = :mem\_cache\_store,  
memcache\_servers, memcache\_options

cache\_params = \*([memcache\_servers, memcache\_options].flatten)  
CACHE = MemCache.new \*cache\_params  
ActionController::CgiRequest::DEFAULT\_SESSION\_OPTIONS.merge!({ ‘cache’  
=\> CACHE })  
config.action\_controller.session\_store = :mem\_cache\_store

then I whittled them down to this:  
config.action\_controller.session\_store = :mem\_cache\_store

neither work with \>= rails 2.1

Hi,  
I have the same problem. try to comment these lines in your  
config/environment.rb:  
config.action\_controller.session = {  
:session\_key =\> ‘\_app\_session’,  
:secret =\> ‘a\_long\_hash\_key’  
}

That’s work for me !  
And I used rails v 2.1
