从Faker为存储在S3中的头像设定种子

Question

我正在开发一个Rails应用程序，我在S3中有一个用于活动存储的has_one_attached个人资料图片，当我为我的用户播种时，我想从Faker中为他们的头像图像播种数据。以下是种子代码：

20.times do
  Student.create(
      first_name: Faker::Name.first_name, 
      last_name: Faker::Name.last_name,
      phone_number: Faker::PhoneNumber.cell_phone,
      school_id: School.first.id,
      vehicle_make_model: Faker::Vehicle.make_and_model,
      vehicle_year: Faker::Vehicle.year,
      vehicle_color: Faker::Vehicle.color,
      email_address: Faker::Internet.email,
      password: "password", 
      email: Faker::Internet.email,
      profile_picture: Faker::Avatar.image
  ).save
end

这是用户的模型，也就是学生模型(这是正确设置的，并且在通过网站上传图像时有效)：

class Student < ApplicationRecord
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable, :trackable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :validatable
  belongs_to :school, optional: true
  has_many :offers
  has_many :comments
  has_many :cars
  has_one_attached :profile_picture
end

我以前已经播种了其余的数据，它工作得很好，但是一旦我集成了S3并尝试播种这些数据，它就不再对我起作用了。

尝试如下所示：

#seed_file
require 'open-uri'

def image_fetcher
    open(Faker::Avatar.image)
    rescue
    open("https://robohash.org/sitsequiquia.png?size=300x300&set=set1")
end

20.times do |n|
  s = Student.create(
     ...
     #remove profile_picture from here
  )

  s.profile_picture.attach({
     io: image_fetcher,
     filename: "#{n}_faker_image.jpg"
  })
end

更新：

require 'faker'
require 'open-uri'

def image_fetcher
  URI.open(Faker::Avatar.image)
  rescue
  URI.open("https://robohash.org/sitsequiquia.png?size=300x300&set=set1")
end
