Let's think about what the call to to_json on the Hash is doing...
Each key/value pair will be sent the message to_json. I assume the Hash
takes care of providing the JSON representation of the more basic types
like String, Fixnum, etc. But, what about when to_json gets sent to the
user object.
Given that Item has_one :user then likely User has_many :items. The item
your working with may be contained within an array of user, if user's
to_json includes items. This might explain how you end up with a "stack
level too deep."
Since I don't know how your User model is behaving I can't say for sure
that is the problem, but it is something to consider.
