I achieved this globally by overriding the following :

module ActionController
module RecordIdentifier
private
def model_name_from_record_or_class(record_or_class)
(record_or_class.is_a?(Class) ? record_or_class.base_class : record_or_class.class.base_class).model_name
end
end
end

The same can be achieved only for specific STI cases with :

@subclassRecord.becomes(BaseClassName)

This saves having extra routes to trawl through and so forth.

Another thank you – I ran into the same situation converting an old app, and you saved me a lot of time!

Javix: The primary reason I do things this way is because, for most purposes, I don’t want to distinguish the different types of tasks in the controller. They’re nearly identical and I want to use the same code. The whole point of the exercise is that ActionItems, WorkOrders etc. all use the same controller action and views so I don’t have to write them twice.

For the few things that need to be different — for example, ProblemReports have one fewer column in the table view than AIs or WOs — I can have my views or controllers check @task.type. For example, in app/views/tasks/show.html.erb I might have this line:

< %- unless @task.type == 'problem_report' %>


< %= h @task.some_field_that_problem_reports_dont_use %>

< % end %>

One more question, – how to distinguish actionitems from others (work_orders, problems_reports) in your controller (new, create, edit, update) and how to create the views? Should I create a seperate folder for every subclass with coresponding views (new, edit, etc.) ?Thanks.

Thanks for this one. Exact same situation for me. Knew there had to be something better than what I was originally up to.
