LoadError (Unable to autoload constant Api::V1::UsersController)

Question

I'm using Rails 5 and I'm getting this error when calling a method in my Api. The thing is, the error only happens sometimes.

LoadError (Unable to autoload constant Api::V1::UsersController, expected /home/user/projects/project-name/app/controllers/api/v1/users_controller.rb to define it):

Relevant part of routes.rb:

Rails.application.routes.draw do
    namespace :api do
        namespace :v1 do
            resources :users
        end
    end
end

Relevant part of the controller:

class Api::V1::UsersController < ApplicationController

I'm clueless of whats wrong, google a lot but couldn't find a solution.

Answer 1

Have you tried adding to the top of your controller module Api module V1 class className < ApplicationController ....

end end end

This should follow your directory structure.
