That's in master branch, but old syntax (without prefix) is supported (with a
deprecation warning).
I think you could get links with set_link method in the controller too. Posted
model mustn't be full, there is no formulation association or method. Does it
exist some formulation association? Then try to call clear_link
Why do you get admin/detail_weeding_select? Are you loading that controller?
Admin::DetailFungicideController configuration won't be used when you load
another controller, helper only will be used if you have helper :all in
application controller.
