[Rails] devise customization. How to change the redirect page after user registration and editing, and how to skip password input when editing

It is a memorandum of a fledgling engineer. This is the first post. Also, it is inefficient to check again when "How do you do that?" Someday, so I will leave it here. Please report any mistakes.

The default is the root path

In my environment, root redirects to the top page, so I want both to transition to the user's details screen. Preparations such as the introduction of devise will be omitted.

1. Creating a controller

$ rails g devise:controllers users

Of the several created controllers, the one I will use this time is registrations_controller.rb

Add here

controllers/users/registrations_controller.rb

class Users::RegistrationsController < Devise::RegistrationsController
  
  #Add the following
  protected

  def after_sign_up_path_for(resource)
    flash[:notice] = 'Completion of registration! You can register your profile image and self-introduction text from the edit button.'
    user_path(resource) #Specify the redirect destination path here
  end

  def after_update_path_for(resource)
    user_path(resource) #Specify the redirect destination path here
  end
end

Now the controller is ready

2. Edit routes.rb

To the created controller class Users::RegistrationsController < Devise::RegistrationsController As you can see, we created a new Users :: RegistrationsController that inherits the Devise :: RegistrationsController originally used in devise, so we will reflect the additional settings by writing here. be able to. (I didn't realize that it was inherited at all, and I was impatient to say, "Do I have to touch all the commented out new actions and update actions to make a new controller?", But it's okay as it is. was) However, since Users :: RegistrationsController cannot be used as it is, It is necessary to clearly describe and use the following.

routes.rb

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

Now you can use the controller you created. You should be redirected to the path you specified.

Setting to skip password input when editing

If it is the default, you will be prompted to enter the password you are setting even if you try to update it. Allows you to update without entering a password. As before, add the following to the controller.

controllers/users/registrations_controller.rb

  def update_resource(resource, params)
    resource.update_without_password(params)
  end

After that, it is ok if you delete the form part of current_password in view.
