Where to place the class describing the exception?

Question

Ruby on Rails

Hello. Where should exception classes be placed in Ruby on Rails? Interested in which directory / file. Is it possible to create a separate file for the code of classes describing exceptions?

Answer 1

There is no standard.
This is how they do it in rails, for example:
https://github.com/rails/rails/blob/master/activer...
If there are few errors, I would first add them to the initializers. If there is a lot, then I would have already added an additional directory to autoload (app/errors/) and divided it by namespaces
