如何从Rails Active Storage中的url附加图像

local:
  service: Disk
  root: <%= Rails.root.join("storage") %>

class Post < ApplicationRecord
  has_one_attached :image
end

post = Post.new
post.image.attach(io: File.open("path/to/your/image.jpg"), filename: "image.jpg", content_type: "image/jpeg")
post.save!

post = Post.last
image_url = post.image.url

<%= image_tag post.image.url %>

thumbnail_url = post.image.variant(resize_to_limit: [100, 100]).url
