Rails 4 Creating Scopes with Application Level Variables

Question

It's possible that I was never doing this properly, but it was working in Rails 3, and now that .scoped is gone it no longer works.

Essentially I have a field in the User table who's value is used to filter almost all other data in the app. In Rails 3 I was using current_user.field_name in the ApplicationController and created methods that used .scoped that were in turn used as before_filter in controllers.

Now that .scoped is gone I need a solution and it probably makes sense to figure out the right way to do this.

To summarize what I need to do:

I need to get a value based on a field for the currently logged in user and then filter a bunch of models based on that value. Is this possible and what is the proper way to do it?

Answer 1

You can use

.where(nil) 

as replacement
