Question

这是我第一次使用ActiveAdmin gem时，我有一个示例应用程序只包含User表（它现在只是一个注册登录注册系统），安装ActiveAdmin gem首先我将它添加到我的gemfile

source 'https://rubygems.org'
ruby "2.5.1"

    gem 'rails',        '5.1.4'
    gem 'activeadmin', '~> 1.3'
    gem 'devise', '~> 4.4', '>= 4.4.3'
    gem 'bootstrap-sass', '3.3.7'
    gem 'bcrypt',       '3.1.12'
    gem 'faker',          '1.7.3'
    gem 'puma',         '3.9.1'
    gem 'sass-rails',   '5.0.6'
    gem 'uglifier',     '3.2.0'
    gem 'coffee-rails', '4.2.2'
    gem 'jquery-rails', '4.3.1'
    gem 'turbolinks',   '5.0.1'
    gem 'jbuilder',     '2.7.0'
    gem 'carrierwave', '~> 0.11.2'

    group :development, :test do
      gem 'sqlite3', '1.3.13'
      gem 'byebug',  '9.0.6', platform: :mri
    end

    group :development do
      gem 'web-console',           '3.5.1'
      gem 'listen',                '3.1.5'
      gem 'spring',                '2.0.2'
      gem 'spring-watcher-listen', '2.0.1'
    end

    group :test do
      gem 'rails-controller-testing', '1.0.2'
      gem 'minitest',                 '5.10.3'
      gem 'minitest-reporters',       '1.1.14'
      gem 'guard',                    '2.13.0'
      gem 'guard-minitest',           '2.4.4'
    end

    group :production do
      gem 'pg', '0.18.4'
    end

    # Windows does not include zoneinfo files, so bundle the tzinfo-data gem
    gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]

然后我跑了

rails g active_admin:install

安装活动管理员，然后我运行迁移更改

rails db:migrate

现在我在运行时遇到错误

rails db:seed

错误是

rails aborted!
SyntaxError: /home/elta3lab/Rails/amazon/db/seeds.rb:25: syntax error, unexpected end-of-input, expecting keyword_end
...ord') if Rails.env.development?
...                               ^

知道这是我的db / seeds.rb文件的内容

User.create!(name:  "Ahmed Mohamed Fouad",
             email: "ahmedfouad@gmail.com",
             password:              "12345678",
             password_confirmation: "12345678",
             activated: true,
             activated_at: Time.zone.now)

User.create!(name:  "Ahmed Fouad",
             email: "elta3lab@gmail.com",
             password:              "12345678",
             password_confirmation: "12345678",
             activated: true,
             activated_at: Time.zone.now)

99.times do |n|
  name  = Faker::Name.name
  email = "example-#{n+1}@railstutorial.org"
  password = "password"
  User.create!(name:  name,
               email: email,
               password:              password,
               password_confirmation: password,
               activated: true,
               activated_at: Time.zone.now)
endAdminUser.create!(email: 'admin@example.com', password: 'password', password_confirmation: 'password') if Rails.env.development?

我觉得这是一个非常简单的问题，但我搜索的时间太长而一无所获。

试试这个，看起来只是围绕最后end，

的不平衡语法

User.create!(name:  "Ahmed Mohamed Fouad",
             email: "ahmedfouad@gmail.com",
             password:              "12345678",
             password_confirmation: "12345678",
             activated: true,
             activated_at: Time.zone.now)

User.create!(name:  "Ahmed Fouad",
             email: "elta3lab@gmail.com",
             password:              "12345678",
             password_confirmation: "12345678",
             activated: true,
             activated_at: Time.zone.now)

99.times do |n|
  name  = Faker::Name.name
  email = "example-#{n+1}@railstutorial.org"
  password = "password"
  User.create!(name:  name,
               email: email,
               password:              password,
               password_confirmation: password,
               activated: true,
               activated_at: Time.zone.now)
end
AdminUser.create!(email: 'admin@example.com', password: 'password', password_confirmation: 'password') if Rails.env.development?

运行错误＆＃34; rails db：seed＆＃34;安装ActiveAdmin gem并运行＆＃34; rails g active_admin：install＆＃34;和＆＃34; rails db：migrate＆＃34;
