1.記述変更 config\initializers\devise.rb(28行目)
ご自分のアドレスを入れて下さい。

2.記述変更 config\initializers\devise.rb(161行目)
tureをfalseに変更します。
config.reconfirmable = false



config\initializers\devise.rb
 
# frozen_string_literal: true 
# Assuming you have not yet modified this file, each configuration option below 
# is set to its default value. Note that some are commented out while others 
# are not: uncommented lines are intended to protect your configuration from 
# breaking changes in upgrades (i.e., in the event that future versions of 
# Devise change the default values for those options). 
# 
# Use this hook to configure devise mailer, warden hooks and so forth. 
# Many of these configuration options can be set straight in your model. 
Devise.setup do |config| 
  # The secret key used by Devise. Devise uses this key to generate 
  # random tokens. Changing this key will render invalid all existing 
  # confirmation, reset password and unlock tokens in the database.

  # by default. You can change it below and use your own secret key. 
  # config.secret_key = '021fcdf799403ffc608a9db54959edb40479b73c6bf88d3395059250137a06c6f9589a55af498f56fe2f9946dcf35ada8ae506f1fc14ad4316bcc3018e69a374'

  # Configure the parent class to the devise controllers. 
  # config.parent_controller = 'DeviseController' 
  # ==> Mailer Configuration

  # Load and configure the ORM. Supports :active_record (default) and 
  # :mongoid (bson_ext recommended) by default. Other ORMs may be 
  # available as additional gems. 
  require 'devise/orm/active_record' 
  # ==> Configuration for any authentication mechanism 
  # Configure which keys are used when authenticating a user. The default is 
  # 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 
  # session. If you need permissions, you should implement that in a before filter. 
  # You can also supply a hash where the value is a boolean determining whether 
  # or not authentication should be aborted when the value is not present. 
  # config.authentication_keys = [:email] 
  # Configure parameters from the request object used for authentication. Each entry 
  # given should be a request method and it will automatically be passed to the 
  # find_for_authentication method and considered in your model lookup. For instance, 
  # if you set :request_keys to [:subdomain], :subdomain will be used on authentication. 
  # The same considerations mentioned for authentication_keys also apply to request_keys. 
  # config.request_keys = [] 
  # Configure which authentication keys should be case-insensitive. 
  # These keys will be downcased upon creating or modifying a user and when used 
  # to authenticate or find a user. Default is :email. 
  config.case_insensitive_keys = [:email] 
  # Configure which authentication keys should have whitespace stripped. 
  # These keys will have whitespace before and after removed upon creating or 
  # modifying a user and when used to authenticate or find a user. Default is :email. 
  config.strip_whitespace_keys = [:email] 
  # Tell if authentication through request.params is enabled. True by default. 
  # It can be set to an array that will enable params authentication only for the 
  # given strategies, for example, `config.params_authenticatable = [:database]` will 
  # enable it only for database (email + password) authentication.

  # It can be set to an array that will enable http authentication only for the 
  # given strategies, for example, `config.http_authenticatable = [:database]` will 
  # enable it only for database authentication. 
  # For API-only applications to support authentication "out-of-the-box", you will likely want to 
  # enable this with :database unless you are using a custom strategy. 
  # The supported strategies are: 
  # :database      = Support basic authentication with authentication key + password 
  # config.http_authenticatable = false 
  # If 401 status code should be returned for AJAX requests. True by default.

  # to behave the same regardless if the e-mail provided was right or wrong. 
  # Does not affect registerable. 
  # config.paranoid = true 
  # By default Devise will store the user in session. You can skip storage for 
  # particular strategies by setting this option. 
  # Notice that if you are skipping storage for all authentication paths, you 
  # may want to disable generating routes to Devise's sessions controller by 
  # passing skip: :sessions to `devise_for` in your config/routes.rb 
  config.skip_session_storage = [:http_auth] 
  # By default, Devise cleans up the CSRF token on authentication to 
  # avoid CSRF token fixation attacks. This means that, when using AJAX 
  # requests for sign in and sign up, you need to get a new CSRF token 
  # from the server. You can disable this option at your own risk. 
  # config.clean_up_csrf_token_on_authentication = true 
  # When false, Devise will not attempt to reload routes on eager load. 
  # This can reduce the time taken to boot the app but if your application 
  # requires the Devise mappings to be loaded during boot time the application 
  # won't boot properly. 
  # config.reload_routes = true 
  # ==> Configuration for :database_authenticatable 
  # For bcrypt, this is the cost for hashing the password and defaults to 12. If 
  # 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 
  # algorithm), the cost increases exponentially with the number of stretches (e.g. 
  # a value of 20 is already extremely slow: approx. 60 seconds for 1 calculation). 
  config.stretches = Rails.env.test? ? 1 : 12

  # Send a notification email when the user's password is changed. 
  # config.send_password_change_notification = false 
  # ==> Configuration for :confirmable 
  # A period that the user is allowed to access the website even without 
  # confirming their account. For instance, if set to 2.days, the user will be 
  # able to access the website for two days without confirming their account, 
  # access will be blocked just in the third day. 
  # You can also set it to nil, which will allow the user to access the website 
  # without confirming their account. 
  # Default is 0.days, meaning the user cannot access the website without 
  # confirming their account. 
  # config.allow_unconfirmed_access_for = 2.days 
  # A period that the user is allowed to confirm their account before their 
  # token becomes invalid. For example, if set to 3.days, the user can confirm 
  # their account within 3 days after the mail was sent, but on the fourth day 
  # their account can't be confirmed with the token any more. 
  # Default is nil, meaning there is no restriction on how long a user can take 
  # before confirming their account. 
  # config.confirm_within = 3.days 
  # If true, requires any email changes to be confirmed (exactly the same way as 
  # initial account confirmation) to be applied. Requires additional unconfirmed_email 
  # db field (see migrations). Until confirmed, new email is stored in 
  # unconfirmed_email column, and copied to email column on successful confirmation. 
  config.reconfirmable = false 
  # Defines which key will be used when confirming an account 
  # config.confirmation_keys = [:email] 
  # ==> Configuration for :rememberable 
  # The time the user will be remembered without asking for credentials again. 
  # config.remember_for = 2.weeks 
  # Invalidates all the remember me tokens when the user signs out. 
  config.expire_all_remember_me_on_sign_out = true 
  # If true, extends the user's remember period when remembered via cookie. 
  # config.extend_remember_period = false 
  # Options to be passed to the created cookie. For instance, you can set 
  # secure: true in order to force SSL only cookies. 
  # config.rememberable_options = {} 
  # ==> Configuration for :validatable 
  # Range for password length. 
  config.password_length = 6..128 
  # Email regex used to validate email formats. It simply asserts that 
  # one (and only one) @ exists in the given string. This is mainly 
  # to give user feedback and not to assert the e-mail validity. 
  config.email_regexp = /\A[^@\s]+@[^@\s]+\z/ 
  # ==> Configuration for :timeoutable 
  # The time you want to timeout the user session without activity. After this 
  # time the user will be asked for credentials again. Default is 30 minutes. 
  # config.timeout_in = 30.minutes 
  # ==> Configuration for :lockable 
  # Defines which strategy will be used to lock an account. 
  # :failed_attempts = Locks an account after a number of failed attempts to sign in. 
  # :none            = No lock strategy. You should handle locking by yourself. 
  # config.lock_strategy = :failed_attempts 
  # Defines which key will be used when locking and unlocking an account 
  # config.unlock_keys = [:email] 
  # Defines which strategy will be used to unlock an account. 
  # :email = Sends an unlock link to the user email 
  # :time  = Re-enables login after a certain amount of time (see :unlock_in below) 
  # :both  = Enables both strategies 
  # :none  = No unlock strategy. You should handle unlocking by yourself. 
  # config.unlock_strategy = :both 
  # Number of authentication tries before locking an account if lock_strategy 
  # is failed attempts. 
  # config.maximum_attempts = 20 
  # Time interval to unlock the account if :time is enabled as unlock_strategy. 
  # config.unlock_in = 1.hour 
  # Warn on the last attempt before the account is locked. 
  # config.last_attempt_warning = true 
  # ==> Configuration for :recoverable 
  # 
  # Defines which key will be used when recovering the password for an account 
  # config.reset_password_keys = [:email] 
  # Time interval you can reset your password with a reset password key. 
  # Don't put a too small interval or your users won't have the time to 
  # change their passwords. 
  config.reset_password_within = 6.hours 
  # 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. 
  # config.scoped_views = false 
  # Configure the default scope given to Warden. By default it's the first 
  # 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. 
  # 
  # The "*/*" below is required to match Internet Explorer requests. 
  # config.navigational_formats = ['*/*', :html] 
  # The default HTTP method used to sign out a resource. Default is :delete. 
  config.sign_out_via = :delete 
  # ==> OmniAuth 
  # Add a new OmniAuth provider. Check the wiki for more information on setting 
  # 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 
end
