一切正常在X天，但随机照片崩溃了...
在视图中，我显示这样的图像：
<%= link_to image_tag(f.image_2.variant(resize_to_fill: [30,30]),
:alt => 'x abc' + f.username.to_s, loading: "lazy" ),
f.image_2.variant(resize_to_limit: [800,600]),
:class=>'large_photo_box fancybox'
%>
class.rb：
has_one_attached :image_1
has_one_attached :image_2
has_one_attached :image_3
contuct.rb：
config.action_controller.perform_caching = true
config.action_controller.enable_fragment_cache_logging = true
config.cache_store = :file_store, "/tmp/my_cache"
config.public_file_server.headers = {
'Cache-Control' => "public, max-age=#{10.days.to_i}"
}
可行，但是... x天后，照片停止显示，没有照片放置了观众的图标。
当它起作用时：
- 当我在新选项卡中复制图像的URL时 -
- 当我打开Chrome开发工具（CTRL + Shift + J）和Reload Page时，图像显示 - 照片再次显示
发生了什么？这里有ROR程序员吗？ ;）
我没有计算几天，但也许问题在生产中。RB缓存？
找不到404的示例：

Everything works ok for X days but then, something crash for random photos ...
In VIEW I display images like this:
<%= link_to image_tag(f.image_2.variant(resize_to_fill: [30,30]),
:alt => 'x abc' + f.username.to_s, loading: "lazy" ),
f.image_2.variant(resize_to_limit: [800,600]),
:class=>'large_photo_box fancybox'
%>
Class has:
has_one_attached :image_1
has_one_attached :image_2
has_one_attached :image_3
Production.rb:
config.action_controller.perform_caching = true
config.action_controller.enable_fragment_cache_logging = true
config.cache_store = :file_store, "/tmp/my_cache"
config.public_file_server.headers = {
'Cache-Control' => "public, max-age=#{10.days.to_i}"
}
It works, but ... after X days the photo stops showing and the no photo icon for the viewer is placed.
When it works:
- when I copy URL for image in new tab - images display
- when I open chrome development tools ( CTRL + SHIFT + J ) and reload page - the photos display again
What is going on? is there any RoR programmer left in here? ;)
I do not calculate days but maybe problem is in production.rb cache ?

如果要为变体的永久性URL，请在
config> config/storage.yml中添加public：true。更多在这里
If you want permanent url for your variants, add
public: truefor your service inconfig/storage.yml.More here
我认为这是解决方案：
“要生成一个斑点的永久URL，您可以将斑点传递到 url_for 视图助手。这会生成一个带有blob的signed_id的URL，该URL被路由到Blob的RedirectController “
如果没有任何错误，将在几天内看到。
I think that this is solution:
"To generate a permanent URL for a blob, you can pass the blob to the url_for view helper. This generates a URL with the blob's signed_id that is routed to the blob's RedirectController"
Will see in few days if there isn't any errors.
