I'm using memcached to cache many AR model objects. I've often wondered if the object's associations are also stored in the memcached during marshaling. Does the act of marshaling an object automatically trigger association loads in the same way that simply referring to an association triggers a load? That would be bad if your objects had many large associations that you didn't want to be stored. Or are only previously-loaded associations marshaled?
If you are using CachedModel only, then no, it takes care of associations not being saved.
But if you are manually marshalling data then yes.
Avoid this by only saving attributes_before_typecast or better yet, only store an integer reference to your object and fetch it with a db query (memcached) on page reload.
