Rails，活动存储，尝试附加照片时出现错误消息

Question

我正在尝试将照片直接附加到 seed.rb 中的实例。但我不认为这是问题所在，因为它在控制台中也不起作用。当我运行 rails db:seed 我收到此错误消息： Errno::ENOENT: No such file or directory @ rb_sysopen - ../app/assets/images/image.jpg

这是我的模型：

class Restaurant < ApplicationRecord
  restaurant_types = ["chinese", "italian", "japanese", "french", "belgian"]
  has_one_attached :photo
  has_many :reviews, dependent: :destroy
  validates :name, :address, :category, :phone_number, presence: true
  validates :category, inclusion: { in: restaurant_types, message: "%{value} is not a valid size" }
end

这是我的种子文件：

require 'open-uri'
require "faker"
puts "deleting all restaurants and reviews"

Review.delete_all
Restaurant.delete_all

puts Restaurant.count
puts Review.count

puts "creating new restaurants"

20.times do
  name = Faker::Restaurant.name
  address = Faker::Address.community
  phone = Faker::PhoneNumber.cell_phone
  category = ["chinese", "italian", "japanese", "french", "belgian"].sample
  restaurant = Restaurant.create(name: name, address: address, phone_number: phone, category: category)
  restaurant.photo.attach(io: File.open('../app/assets/images/image.jpg'), filename: 'image')
end

而且我还在我的 config/application.rb 文件中包含了 require "active_storage/engine"。

这是我的应用程序文件夹以及我的 seed.rb 和 image.jpg 文件所在的位置。显然 link?

有问题

有人知道我做错了什么吗？谢谢！

Answer 1

您需要通过Rails.root

获取您的应用程序的路径

在你的种子文件中更改为这个并尝试

restaurant.photo.attach(io: File.open(Rails.root.join("app", "assets", "images", "image.jpg")), filename: 'image.jpg')

您也可以将其存储在变量中

file_path = Rails.root.join("app", "assets", "images", "image.jpg")
restaurant.photo.attach(io: File.open(filepath), filename: 'image.jpg')

此外，添加文件存在的条件

File.exist? file_path
