お部屋を登録したホストに宿泊料金の80%が自動で支払われるように設定します。
これにはStripeコネクトというサービスを使いますが、プランに「スタンダード」と「エクスプレス」があります。
「エクスプレス」の方がホストの登録や設定が楽なので「エクスプレス」で実装していきます。


「テスト環境のクライアント ID」の取得方法は下記の手順でお願いします。

  # just :email. You can configure it to use [:username, :subdomain], so for 
  # authenticating a user, both parameters are required. Remember that those 
  # parameters are used only when authenticating and not when retrieving from

  # For API-only applications to support authentication "out-of-the-box", you will likely want to

  # using other algorithms, it sets how many times you want the password to be hashed. 
  # The number of stretches used for generating the hashed password are stored 
  # with the hashed password. This allows you to change the stretches without 
  # invalidating existing passwords. 
  # 
  # Limiting the stretches to just one in testing will increase the performance of 
  # your test suite dramatically. However, it is STRONGLY RECOMMENDED to not use 
  # a value less than 10 in other environments. Note that, for bcrypt (the default

  # able to access the website for two days without confirming their account, 
  # access will be blocked just in the third day.

  # config.reset_password_keys = [:email] 
  # Time interval you can reset your password with a reset password key.

  # change their passwords.

  # When set to false, does not sign a user in automatically after their password is 
  # reset. Defaults to true, so a user is signed in automatically after a reset. 
  # config.sign_in_after_reset_password = true 
  # ==> Configuration for :encryptable 
  # Allow you to use another hashing or encryption algorithm besides bcrypt (default). 
  # You can use :sha1, :sha512 or algorithms from others authentication tools as 
  # :clearance_sha1, :authlogic_sha512 (then you should set stretches above to 20 
  # for default behavior) and :restful_authentication_sha1 (then you should set 
  # stretches to 10, and copy REST_AUTH_SITE_KEY to pepper). 
  # 
  # Require the `devise-encryptable` gem when using anything other than bcrypt 
  # config.encryptor = :sha512 
  # ==> Scopes configuration 
  # Turn scoped views on. Before rendering "sessions/new", it will first check for 
  # "users/sessions/new". It's turned off by default because it's slower if you 
  # are using only default views.

  # devise role declared in your routes (usually :user). 
  # config.default_scope = :user 
  # Set this configuration to false if you want /users/sign_out to sign out 
  # only the current scope. By default, Devise signs out all scopes. 
  # config.sign_out_all_scopes = true 
  # ==> Navigation configuration 
  # Lists the formats that should be treated as navigational. Formats like 
  # :html, should redirect to the sign in page when the user does not have 
  # access, but formats like :xml or :json, should return 401. 
  # 
  # If you have any extra navigational formats, like :iphone or :mobile, you 
  # should add them to the navigational formats lists.

  # up on your models and hooks. 
  # config.omniauth :github, 'APP_ID', 'APP_SECRET', scope: 'user,public_repo' 
  # ==> Warden configuration 
  # If you want to use other strategies, that are not supported by Devise, or 
  # change the failure app, you can configure them inside the config.warden block. 
  # 
  # config.warden do |manager| 
  #   manager.intercept_401 = false 
  #   manager.default_strategies(scope: :user).unshift :some_external_strategy 
  # end 
  # ==> Mountable engine configurations 
  # When using Devise inside an engine, let's call it `MyEngine`, and this engine 
  # is mountable, there are some extra configurations to be taken into account. 
  # The following options are available, assuming the engine is mounted as: 
  # 
  #     mount MyEngine, at: '/my_engine' 
  # 
  # The router that invoked `devise_for`, in the example above, would be: 
  # config.router_name = :my_engine 
  # 
  # When using OmniAuth, Devise cannot automatically set OmniAuth path, 
  # so you need to do it manually. For the users scope, it would be: 
  # config.omniauth_path_prefix = '/my_engine/users/auth' 
  # ==> Turbolinks configuration 
  # If your app is using Turbolinks, Turbolinks::Controller needs to be included to make redirection work correctly: 
  # 
  # ActiveSupport.on_load(:devise_failure_app) do 
  #   include Turbolinks::Controller 
  # end 
  # ==> Configuration for :registerable 
  # When set to false, does not sign a user in automatically after their password is 
  # changed. Defaults to true, so a user is signed in automatically after changing a password. 
  # config.sign_in_after_change_password = true
