500 error with nested scaffolds and ActionController::Caching::Sweeper #753

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Set up a caching sweeper (such as with acts_as_audited - though any caching 
sweeper on your scaffolded controllers should do)
2. enable caching (config.action_controller.perform_caching = true)
3. Configure scaffolding for 2 associated models so that you can trigger the 
nested action ( A has_many B) 
4. Navigate to the parent model scaffold in browser
5. click on association link for nested display

What is the expected output? What do you see instead?

Expected: Nested tabular display

Actual:
NoMethodError in Admin/partnersController#nested
undefined method `controller_name' for nil:NilClass

What version (or revision) of the product are you using?

Most recent master from github 
(http://github.com/activescaffold/active_scaffold/tree/8033adef7606a04d592607c3e
ad965e612119daf)

According those bug reports it's a rails/action_pack bug, or a misuse of 
cache_action
