When I created a user my page, the user editing function of devise became strange.

Overview

In the app that implemented the user management function using devise, the edit page disappeared when I created my page.

environment

Rails 6.0.0 Ruby 2.6.5

Cause

The user edit page was not displayed as intended due to the order in which the routes were displayed. The URI of My Page is ʻusers / (user.id), and the edit page is set to ʻusers / edit.

When I checked params, it said " id "=>" edit ", It seems that the cause was that I was trying to display my page by misunderstanding edit as user.id for some reason.

Error statement

ActiveRecord::RecordNotFound in UsersController#show
Couldn't find User with 'id'=edit

The routing looks like this

routes.rb

Rails.application.routes.draw do
  resources :users, only: :show
  devise_for :users, controllers: {
    registrations: 'users/registrations'
  }
end

Only the relevant part

                                 user GET    /users/:id(.:format)                                                                     users#show

                                      POST   /users(.:format)                                                                         users/registrations#create

solution

Changed the order of routing. All I had to do was put resources: users, only:: show underdevise_for: users, controllers: {registrations:'users / registrations'}so that the edit page takes precedence.

routes.rb

Rails.application.routes.draw do
  devise_for :users, controllers: {
    registrations: 'users/registrations'
  }
  resources :users, only: :show # devise_Changed to be described under for
end

                     new_user_session GET    /users/sign_in(.:format)                                                                 devise/sessions#new
                         user_session POST   /users/sign_in(.:format)                                                                 devise/sessions#create
                 destroy_user_session DELETE /users/sign_out(.:format)                                                                devise/sessions#destroy
                    new_user_password GET    /users/password/new(.:format)                                                            devise/passwords#new
                   edit_user_password GET    /users/password/edit(.:format)                                                           devise/passwords#edit
                        user_password PATCH  /users/password(.:format)                                                                devise/passwords#update
                                      PUT    /users/password(.:format)                                                                devise/passwords#update
                                      POST   /users/password(.:format)                                                                devise/passwords#create
             cancel_user_registration GET    /users/cancel(.:format)                                                                  users/registrations#cancel
                new_user_registration GET    /users/sign_up(.:format)                                                                 users/registrations#new
#Edit page takes precedence
               edit_user_registration GET    /users/edit(.:format)                                                                    users/registrations#edit
                    user_registration PATCH  /users(.:format)                                                                         users/registrations#update
                                      PUT    /users(.:format)                                                                         users/registrations#update
                                      DELETE /users(.:format)                                                                         users/registrations#destroy
                                      POST   /users(.:format)                                                                         users/registrations#create
#My page is listed here
                                 user GET    /users/:id(.:format)                                                                     users#show

Summary

Not limited to routing, program processing is executed from above, so it is better to implement with that in mind. I think it's okay if you understand routing well, but I wrote it because there was no article even if I looked it up.
