Devise does not redirect to root after sign in-CodePudding

I have a rails app which uses devise, rails version 6.0.3.6. Until yesterday, when a user signed in, they got redirected to a user dashboard (as desired) which I declared as root in my routes.rb file.

This changed however when I added a new route for an API using a namespace. Now the user gets redirected to the page of the API (which is /api/v1/circles) after login and I want them to get redirected to the user dashboard again.

I tried several things I found on the web like

changing the order of routes in routes.rb
specify the root route in different ways or
define a redirect_after_sign_in method in application_controller.rb

I couldn't make it work. Why would devise not redirect to root anymore?

routes.rb:

Rails.application.routes.draw do
  devise_for :users
...
  root to: 'pages#user_dashboard'
...
resources :circles, only: [:create, :index, :show, :edit, :update, :destroy]
...
  namespace :api do
    namespace :v1 do
      get 'circles', to: 'circles#index'
    end
  end
end

rails routes:

...
          root GET    /                            pages#user_dashboard
...
api_v1_circles GET    /api/v1/circles(.:format)    api/v1/circles#index
...

Have you tried adding the following in your routes.rb file?

authenticated :user do
  root to: "pages#user_dashboard", as: :authenticated_root
end

CodePudding user response：

Someone else pointed me to this solution:

in application_controller.rb I added

def after_sign_in_path_for(resource)
  root_path
end
