How to sign_in user after devise email confirmation in Rails

Question

I am trying from last 7 hours to auto signin the user after email confirmation but when I click the confirmation link then it says "Your email address has been successfully confirmed." but not sign in the user. I have written this code in my confirmations controller and route

devise_for :users, controllers: {confirmations: 'users/confirmations'}

class ConfirmationsController < Devise::ConfirmationsController
  #private
  def after_confirmation_path_for(resource_name, resource)
    sign_in(resource)
    render plain: "here"
    redirect_to "/admins/view_account", notice: "User deleted."
  end
end

Any help would be highly appreciated Thanks.

Answer 1

Notice that automatically sign in after e-mail confirmation used to be Devise's default behavior and was then changed (after 3.1 ) due to security measures as you can see more here and here .

If you still want to do it, depending on the Devise's version make sure to set the line below on the config/initializers/devise.rb file within your project:

config.allow_insecure_sign_in_after_confirmation=true

If you are using latest Devise version, you may have to instead of that, extend the default controller with this code on app/controllers/users/confirmations_controller.rb as a replacement of what you have mentioned above for controller code ( please mind the namespaces and path mentioned ):

class Users::ConfirmationsController < Devise::ConfirmationsController
  def show
    super do |resource|
      sign_in(resource) if resource.errors.empty?
    end
  end
end

And make sure the code you pasted in the beginning of the question belongs in config/routes.rb :

devise_for :users, controllers: { confirmations: 'users/confirmations' }

Hope it helps!

I have solved it myself.

routes should be like this

 devise_for :users, controllers: {confirmations: 'confirmations'} do
    #put "confirm_user", to: "confirmations#confirm_user"
    get "confirmation", to: "confirmations#after_confirmation_path_for"
  end

Controller is like this

class ConfirmationsController < Devise::ConfirmationsController
  #private
   def after_confirmation_path_for(resource_name, resource)
    sign_in(resource)
    #render plain: "here"
    #redirect_to "/admins/"
   end

  def show
    self.resource = resource_class.confirm_by_token(params[:confirmation_token])

    if resource.errors.empty?
      set_flash_message(:notice, :confirmed) if is_flashing_format?
      sign_in(resource) # <= THIS LINE ADDED
      redirect_to "/your path/"
    else
      respond_with_navigational(resource.errors, :status => :unprocessable_entity){ render :new }
    end
  end


end
