Question

我使用他们的cleardb mysql add on在heroku上托管了一个简单的rails应用程序。我在本地开发mysql。我在heroku上的生产数据库中播种数据时遇到问题。

我的种子数据在db / seeds.rb中看起来像这样。该应用程序正在使用faker和制作宝石。我有一个用户模型和一个人模型。

Fabricator(:user) do 
  first_name { Faker::Name.first_name }
  last_name { Faker::Name.last_name }
  birthday { Faker::Date.backward(14000) }
  phone_number { Faker::PhoneNumber.phone_number }
  street { Faker::Address.street_address }
  city { Faker::Address.city }
  state { Faker::Address.state_abbr }
  zip_code { Faker::Address.zip }
  education { "Bachelor" }
  image { File.open("app/assets/images/helloworld.jpg")}
end 

Fabricator(:person) do 
  full_name { Faker::Name.name }
  email { Faker::Internet.email }
  image { File.open("app/assets/images/puppy.jpg")}
  friend_test { 0 }
  user
end 

#40.times { Fabricate(:user)} #comment this out because running the below command will generate user already
40.times { Fabricate(:person)}

Person.create(full_name: "Ben Franklin", email: "ben@gmail.com", friend_test: 0, image: File.open("app/assets/images/puppy.jpg"), user_id: 1)
Person.create(full_name: "George Washington", email: "george@gmail.com", friend_test: 0, image: File.open("app/assets/images/puppy.jpg"), user_id: 1)
Person.create(full_name: "John Adam", email: "john@gmail.com", friend_test: 0, image: File.open("app/assets/images/puppy.jpg"), user_id: 1)


Person.create(full_name: "Barack Obama", email: "barack@gmail.com", friend_test: 0, image: File.open("app/assets/images/puppy.jpg"), user_id: 2)
Person.create(full_name: "John Kennedy", email: "john@gmail.com", friend_test: 0, image: File.open("app/assets/images/puppy.jpg"), user_id: 2)
Person.create(full_name: "Andrew Jackson", email: "andrew@gmail.com", friend_test: 0, image: File.open("app/assets/images/puppy.jpg"), user_id: 2)


Person.create(full_name: "Jimmy Carter", email: "jimmy@gmail.com", friend_test: 0, image: File.open("app/assets/images/puppy.jpg"), user_id: 3)
Person.create(full_name: "Gerald Ford", email: "gerald@gmail.com", friend_test: 0, image: File.open("app/assets/images/puppy.jpg"), user_id: 3)
Person.create(full_name: "Richard Nixon", email: "richard@gmail.com", friend_test: 0, image: File.open("app/assets/images/puppy.jpg"), user_id: 3)

最初我认为它没有正确播种，因为我没有正确清除数据库（因为heroku不能很好地使用mysql）。我完成了所有这些步骤，并且我认为我缩小了播种动作的问题。

heroku run rake db:drop
heroku run rake db:create
heroku run rake db:migrate 
heroku run rake db:setup
heroku run rake db:seed #problem

当我跑

时

heroku run rails console

并执行User.all

创建种子数据User_id = 1然后跳转到User_id = 11然后User_id = 21.这与Person模型相同。这是非常奇怪的，因为本地我在本地运行这些命令时，我只会得到1到40的用户ID，并且从1到40的person_id也是如此。我的本地数据库很好。我在视图中有逻辑，它取决于记录逐一进行，而不是随机进行。

是的我在本地和生产中使用mysql，这是我的database.yml文件

development:
  adapter: mysql2
  encoding: utf8
  database: mini_facebook_development
  pool: 5
  username: root
  password:
  socket: /tmp/mysql.sock

staging:
  adapter: mysql2
  encoding: utf8
  database: mini_facebook_staging
  pool: 5
  username: root
  password:
  socket: /tmp/mysql.sock

test:
  adapter: mysql2
  encoding: utf8
  database: mini_facebook_test
  pool: 5
  username: root
  password:
  socket: /tmp/mysql.sock

并且是

gem 'mysql2', '~> 0.3.17'

我没有在这里设置生产。我正在使用heroku配置和heroku文档，无论如何都会生成database.yml。
