cache issue with attr_accessor field

rubyonrails-talk

Hi,

I've got a model with the following attribute added:

   attr_accessor :level

which does not exist in the database. After putting instances of this model in the cache (using Rails.cache.fetch('foo') { Category.all } ), when I retrieve it back from the cache, then trying to access .level gives:

  undefined method `level' for #<Category:0x34d50a0>

I'm simply using the memorystore. In script/console it works fine, just not when in script/server. Anybody knows what's happening here?

Best regards, Jimmy

I suspect rails' automatic reloading is tripping you up here. If it works when you enable class caching (in development.rb) then it's definitely the automatic reloading.
