My tests indicate that, when running in development mode, Rails removes
‘association’ methods (e.g. a method created for has_many) after the
processing of a request completes. I assume they are removed from the
class object for the given instance object.
For example, my code is as follows:
class Picklist < ActiveRecord::Base
class ListItems < ActiveRecord::Base
I also have a singleton factory class called ‘PicklistFactory’ which
allows me to:
This returns me an object of class Picklist.
The idea is that the factory object is created once only and will
return Picklist objects on-demand. The create method checks if an
object exists and if so returns it, otherwise creates an object
containing all available Picklist objects in the database.
I observe that the factory object and its referenced Picklist objects
‘stay around’ between HTTP requests but the association method
list_items is not available for subsequent requests and throws an
I’d like to understand why the association method disappears and
whether this would be the case in production (require-mode).
Any pointers/thoughts appreciated.
