Rails 6 - Issue with nested resources in a namespace - ruby-on-rails

Question

So I am trying to nest resources under a namespace, however when i try to navigate to the UserProfile new page I am hitting the following error:
ActionController::RoutingError at /users/xxxxxx/user_profiles/new
uninitialized constant AccountManagementPages::UserProfilesController
Did you mean? AccountManagementPages::UsersController
This is how the resources are set up in my routes.rb file
constraints(AccountManagement) do
namespace :account_management_pages, path: '' do
root to: 'users#new', as: :registration
resources :users, except: %w[index], path_names: { new: 'register' } do
resources :user_profiles
end
end
end
my file structure for both my controller and views are configured correctly (at least I thought they were).
And here is how my views are nested.
This is how I have my user_profiles_controller configured:
module AccountManagementPages
module Users
class UserProfilesController < ApplicationController
def show; end
def new; end
def edit; end
def create; end
def update; end
end
end
end
and my model associations (don't think this is overly relevant here but just incase it is.)
class User < ApplicationRecord
has_one :user_profile, dependent: :destroy
end
class UserProfile < ApplicationRecord
belongs_to :user
end
any help here would be greatly appreciated. Not sure why I am hitting this error?
Thanks in advance.

If you do rails routes, you'll get (amongst other things):
Prefix Verb URI Pattern Controller#Action
account_management_pages_registration GET / account_management_pages/users#new
account_management_pages_user_user_profiles GET /users/:user_id/user_profiles(.:format) account_management_pages/user_profiles#index
POST /users/:user_id/user_profiles(.:format) account_management_pages/user_profiles#create
new_account_management_pages_user_user_profile GET /users/:user_id/user_profiles/register(.:format) account_management_pages/user_profiles#new
edit_account_management_pages_user_user_profile GET /users/:user_id/user_profiles/:id/edit(.:format) account_management_pages/user_profiles#edit
account_management_pages_user_user_profile GET /users/:user_id/user_profiles/:id(.:format) account_management_pages/user_profiles#show
PATCH /users/:user_id/user_profiles/:id(.:format) account_management_pages/user_profiles#update
PUT /users/:user_id/user_profiles/:id(.:format) account_management_pages/user_profiles#update
DELETE /users/:user_id/user_profiles/:id(.:format) account_management_pages/user_profiles#destroy
account_management_pages_users POST /users(.:format) account_management_pages/users#create
new_account_management_pages_user GET /users/register(.:format) account_management_pages/users#new
edit_account_management_pages_user GET /users/:id/edit(.:format) account_management_pages/users#edit
account_management_pages_user GET /users/:id(.:format) account_management_pages/users#show
PATCH /users/:id(.:format) account_management_pages/users#update
PUT /users/:id(.:format) account_management_pages/users#update
DELETE /users/:id(.:format) account_management_pages/users#destroy
As you can see, user_profiles is not nested under the users namespace. Rails, therefore, is expecting:
module AccountManagementPages
class UserProfilesController < ApplicationController
...
end
end
If you do:
constraints(AccountManagement) do
namespace :account_management_pages, path: '' do
root to: 'users#new', as: :registration
resources :users, except: %w[index], path_names: { new: 'register' } do
scope module: :users do
resources :user_profiles
end
end
end
end
...and then rails routes, you get (amongst other things):
Prefix Verb URI Pattern Controller#Action
account_management_pages_registration GET / account_management_pages/users#new
account_management_pages_user_user_profiles GET /users/:user_id/user_profiles(.:format) account_management_pages/users/user_profiles#index
POST /users/:user_id/user_profiles(.:format) account_management_pages/users/user_profiles#create
new_account_management_pages_user_user_profile GET /users/:user_id/user_profiles/register(.:format) account_management_pages/users/user_profiles#new
edit_account_management_pages_user_user_profile GET /users/:user_id/user_profiles/:id/edit(.:format) account_management_pages/users/user_profiles#edit
account_management_pages_user_user_profile GET /users/:user_id/user_profiles/:id(.:format) account_management_pages/users/user_profiles#show
PATCH /users/:user_id/user_profiles/:id(.:format) account_management_pages/users/user_profiles#update
PUT /users/:user_id/user_profiles/:id(.:format) account_management_pages/users/user_profiles#update
DELETE /users/:user_id/user_profiles/:id(.:format) account_management_pages/users/user_profiles#destroy
account_management_pages_users POST /users(.:format) account_management_pages/users#create
new_account_management_pages_user GET /users/register(.:format) account_management_pages/users#new
edit_account_management_pages_user GET /users/:id/edit(.:format) account_management_pages/users#edit
account_management_pages_user GET /users/:id(.:format) account_management_pages/users#show
PATCH /users/:id(.:format) account_management_pages/users#update
PUT /users/:id(.:format) account_management_pages/users#update
DELETE /users/:id(.:format) account_management_pages/users#destroy
...and user_profiles will be nested under users. And you should be able to use:
module AccountManagementPages
module Users
class UserProfilesController < ApplicationController
...
end
end
end
