Caching a model ????

Hi,

I am using memcahced_client for caching. I also have cached_model installed as a gem install. I have a user object that in turn has a hasmany relationship to a reviews model.

So, once user logs in, i have soemthing like

@reviews = @user_profile.reviews

and reviews has been defined as follows in the user_profile model

# Reviews   has_many :reviews, :class_name => "UserReviews", :foreign_key => :user_id, :limit => 1000, :order => :review_date

I then try to cache the @reviews using

Cache.put key,@reviews.

Next i try to retreive it using

Cache.get key

Here is my code for that. begin         @reviews = Cache.get @user_profile.user_id.to_s+'_reviews'       rescue         @reviews = nil       end       if @reviews == nil         @reviews = @user_profile.reviews         Cache.put @user_profile.user_id.to_s+'_reviews', @reviews       end

Neither the put nor the get seem to be working. I think it has something to do with the marshalling. Can anyone help?

Thanks in advance Deepa.
