I am using rjs to perform ajax deletes on objects within an array @instructions. The objects within the array @instructions vary
depending on some other logic in my controller and is not dependent on
direct correlations within the database. In other words, when I
update the partial with:
The @instructions cannot just be populated by active record
correlations such as: @day.instructions.
The logic used in the controller to populate the @instructions
variable is expensive and I would prefer not to go through the logic
again if possible. What is the best option for this situation, would
using some caching method be best, or is there a way to store the @instructions variable in a flash or params or something?

Probably the best way would be to cache the whole HTML
partial using Rails’ partial-cache capability. You would
use a custom cache key that’s built on the set of controller
parameters that influence the contents of the @instructions
collection.
