Hey, could you add some information:

• are the references to the images disappearing from code or is the image file not served?
• are you using a CDN or reverse proxy (cloudflare or anything)?
• are the images still reachable via direct link?
• are you using any local webserver to reverse proxy such as nginx?

Image is not being served and appears as a broken link.

.url generates
https://hostname/rails/active_storage/disk/##REF##

url_for generates

https://hostname/rails/active_storage/representations/redirect/##REF##

Storage is local to the server using the Disk service.

No proxies are involved. Web server is Apache2/Passenger

The proposed fix (#403) only fixes it when ActiveStorage uses the "local" backend. Most stores use some kind of object storage, like S3, so we need a different fix.

This is an interesting issue, because the usual solution is for the store operator to configure ActiveStorage to generate public URLs, but this is a very common stumbling block. Moving the caching to avoid caching the images is probably a good solution.

@jarednorman can you elaborate what you mean by moving?

@jarednorman Out of interest why would you not want to use the url_for helper? https://guides.rubyonrails.org/active_storage_overview.html#serving-files suggests this is the correct way to handle them.

@magpieuk Oh, I was mistaken about how that worked. That is probably the right solution. My mistake.
