Rails, active storage, Error message when I try to attach a photo

Question

I am trying to attach a photo to instances in the seed.rb directly. But I don't think that is the issue, because it doesn't work in the console either. When I run rails db:seed I get this error message: Errno::ENOENT: No such file or directory @ rb_sysopen - ../app/assets/images/image.jpg

Here is my Model:

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

Here is my seed file:

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

And I also included require "active_storage/engine" in my config/application.rb file.

And here is my application folder and where both my seed.rb and image.jpg files are located. Apparently there is something wrong with the link?

Anyone knows what I am doing wrong? Thanks!

You need to get the path of your application by Rails.root

change to this in your seed file and try

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

You can store this in a variable also

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

Also, add a condition for file exist

File.exist? file_path
