Module: Toller::ScopeResolver

Defined in:
lib/toller/scope_resolver.rb

Overview

Shared lookup used by the type: :scope filter/sort handlers to confirm a resolved scope_name/field is actually declared on the model (a real scope, or a plain def self.foo), rather than a method inherited from ActiveRecord itself. Without this, a typo'd scope_name: that happens to collide with a built-in ActiveRecord class method (delete_all, where, sum, etc.) would silently public_send it with the raw request value instead of being treated as an unresolvable scope.
