我有一个带有头像的员工模型。我可以将图像附加到头像,但每当我尝试显示图像时,
url_for(@employee.avatar)
产生死链接。我所看到的只是来自的价值alt来自标签的属性。我得到的图像标签如下
<img src="/rails/active_storage/blobs/eyJfcmFpbHMiOnsibWVzc2FnZSI6IkJBaHBDZz09IiwiZXhwIjpudWxsLCJwdXIiOiJibG9iX2lkIn19--4786aa4d9d82d8f8d572b857965088b20fcb2f49/Portrait.jpg"
alt="Thumbnail">
我知道图像已正确附加。当我调用以下命令时,我得到这个结果:
@employee.avatar
=> #<ActiveStorage::Attached::One:0x00007ff7e9ba41c0 @name="avatar",
@record=#<Employee id: 4, first_name: "Meda", last_name: "Burgdorf",
created_at: "2019-03-03 23:03:00", updated_at: "2019-03-03 23:17:56">,
@dependent=:purge_later>
as I can see the image in the storage directory
非常感谢您的帮助。谁能帮我显示保存的图像。
这是我的设置。
class Employee < ApplicationRecord
has_one_attached :avatar
...
end
我的 storage.yml 文件的内容
local:
service: Disk
root: <%= Rails.root.join("storage") %>
