Ruby on Rails 6 加载模块

Question

I would like to know what is the right way to use a class with namespace in rails 6. I have the follow, but it isn't working and I'm receiving the error:

"Uninitialized constant ProductsController::Operations Did you mean? ProductsController::Options"

#app/operations/create.rb
module Operations
  class Create
    def self.foo
      ...
    end
  end
end

#app/controllers/products_controller.rb

class ProductsController < ApplicationController
  def create
    Operations::Create.foo
  end
end

Can you help me please?

Answer 1

Your module should be inside of any folder. For example app/services/operations/create.rb (any name will work) with the same content you have:

module Operations
  class Create
    def self.foo
      ...
    end
  end
end

and call it Operations::Create.foo .

Also make sure you restart spring with spring stop .
