Here to share my solution:
Got it working without hardcoding of any controller/model names, hence
should be easily deployable to any other controller
I have put the following into my Contractversion controller:
def conditions_for_collection
# we need to remove the text "version" from the end of the
controller name to get the originating controller
source_controller =
self.controller_name.camelize[0..self.controller_name.length-8]
c = eval(source_controller.to_s
+
".find_by_id
(active_scaffold_constraints[active_scaffold_constraints.keys[0]])")
# Could also use params[:controller].camelize to get the
controller name, but I am not sure whether that covers all cases
return [eval(self.controller_name.camelize.to_s
+".table_name").to_s+".version <> ?", c.version] unless c.nil?
return ""
end
I am not sure whether this is the most elegant way, recommendations of
simplifying this are most welcome.
