rails latest stable - Class:
ActiveSupport::ErrorReporter
add_middleware(middleware)public
Add a middleware to modify the error context before it is sent to subscribers.
Middleware is added to a stack of callables run on an error’s execution context before passing to subscribers. Allows creation of entries in error context that are shared by all subscribers.
A context middleware receives the same parameters as #report. It must return a hash - the middleware stack returns the hash after it has run through all middlewares. A middleware can mutate or replace the hash.
Rails.error.add_middleware(-> (error, context) { context.merge({ foo: :bar }) })
