【问题描述】：

我正在通过他的种子文件填充一个 Rails 应用程序，并想为每个帐户附加一张图片，但它不起作用，我不知道为什么。

我阅读了 ActiveStorage 文档并尝试应用我在 Stackoverflow 上的两个不同答案中找到的解决方案，但无济于事，我可以

我收到以下错误：

> Clearing Database...
> Creating users...
rails aborted!
ActiveStorage::IntegrityError: ActiveStorage::IntegrityError
/mnt/c/Users/pedro/code/ruby-projects/tinder-clone/db/seeds.rb:20:in `block in <main>'
/mnt/c/Users/pedro/code/ruby-projects/tinder-clone/db/seeds.rb:12:in `times'
/mnt/c/Users/pedro/code/ruby-projects/tinder-clone/db/seeds.rb:12:in `<main>'

./bin/rails:3:in `load'
./bin/rails:3:in `<main>'
Tasks: TOP => db:seed

这是我的种子文件：

require 'faker'
require "open-uri"


puts "> Clearing Database..."
Account.destroy_all

puts "> Creating users..."

FILE = File.open('app/assets/images/portrait.jpg')

15.times do 
  account = Account.create(
    first_name: Faker::Name.first_name,
    last_name: Faker::Name.last_name,
    username: Faker::Games::Witcher.monster,
    email: Faker::Internet.email,
    password: "123456",
  )
  account.images.attach(io: FILE, filename: 'person.jpg', content_type: 'image/jpg')

end

puts "> Done!"

这是我的模型：

class Account < ApplicationRecord
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable, :trackable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :validatable

  has_many_attached :images

end

感谢您的帮助，谢谢！

【解决方案1】：

ActiveStorage::IntegrityError 在上传或下载的数据损坏时引发（与预先计算的校验和不匹配）。当您使用faker gem时，我建议您执行以下操作：


url = Faker::Avatar.image(slug: 'my-own-slug', size: '250x250')
filename = File.basename(URI.parse(url).path)
file = URI.open(url)

15.times do 
  account = Account.create(
    first_name: Faker::Name.first_name,
    last_name: Faker::Name.last_name,
    username: Faker::Games::Witcher.monster,
    email: Faker::Internet.email,
    password: "123456",
  )
  account.images.attach(io: file, filename: filename)
end
