Devise添加电子邮件确认的问题

如何解决Devise添加电子邮件确认的问题

我想使用Devise在我的Rails应用程序中添加电子邮件确认。我收到此错误消息：

“ Devise :: RegistrationsController＃create中的NoMethodError MailForm :: Base：Class的未定义方法`confirmation_instructions'

schema.rb

create_table "users",force: :cascade do |t|
    t.string "email",default: "",null: false
    t.string "encrypted_password",null: false
    t.string "reset_password_token"
    t.datetime "reset_password_sent_at"
    t.datetime "remember_created_at"
    t.datetime "created_at",null: false
    t.datetime "updated_at",null: false
    t.string "username"
    t.string "first_name"
    t.string "last_name"
    t.float "latitude"
    t.float "longitude"
    t.boolean "admin",default: false
    t.string "confirmation_token"
    t.datetime "confirmed_at"
    t.datetime "confirmation_sent_at"
    t.string "unconfirmed_email"
    t.index ["email"],name: "index_users_on_email",unique: true
    t.index ["reset_password_token"],name: "index_users_on_reset_password_token",unique: true
  end

user.rb

class User < ApplicationRecord

  devise :database_authenticatable,:registerable,:recoverable,:rememberable,:validatable,:confirmable
end

routes.rb

Rails.application.routes.draw do
  devise_for :users

  resources :users do
    member do
      get :confirm_email
    end
  end

devise.rb

Devise.setup do |config|
config.mailer_sender = '[e-mail]'

  #mail_form
  config.mailer = 'MailForm::Base'
end

development.rb

  config.action_mailer.default_url_options = { host: "https://myapp.com" }
  config.action_mailer.perform_deliveries = true
  config.action_mailer.raise_delivery_errors = true
  config.action_mailer.delivery_method = :smtp
  config.action_mailer.smtp_settings = {
    address: 'smtp.gmail.com',port: 587,domain: 'gmail.com',authentication: 'plain',enable_starttls_auto: true,user_name: ENV['GMAIL_EMAIL'],password: ENV['GMAIL_PASSWORD']
  }

production.rb

config.action_mailer_default_url_options = { host: 'https://myapp.com' }
  Rails.application.routes.default_url_options[:host] = 'https://myapp.com'
  config.action_mailer.delivery_method = :smtp
  config.action_mailer.perform_deliveries = true
  config.action_mailer.raise_delivery_errors = false
  config.action_mailer.default charset: 'utf-8'
  config.action_mailer.smtp_settings = {
    address: 'smtp.gmail.com',password: ENV['GMAIL_PASSWORD']
  }

这是因为mail_form gem用于联系表格吗？我应该创建RegistrationController吗？有人能猜出这里的主要问题吗？

解决方法

confirmation_instructions是在Devise mailer

上定义的方法

尝试在 devise.rb

中更改邮件程序配置

Devise.setup do |config|
  config.mailer_sender = '[e-mail]'
  config.mailer = 'Devise::Mailer'
end
