Support images with query strings on them about imgix-rb HOT 6 CLOSED

sure... we are doing that too. Ideally this code would be smart enough that we wouldn't have to though!

from imgix-rb.

We have this same setup with cloudfront. You could probably do something like this... Check if the string contains more than one '?'. If it does replace any following with '&'

@benhutton what are you doing to work around this? I'm having trouble using a cache busting timestamp

from imgix-rb.

@axelson I've moved away from timestamps to asset fingerprinting based based on an md5 hash of the file contents. So, your filename looks like filename-hash.ext. Here's an actual URL we're using: https://dg.imgix.net/waiting-for-god-to-text-back-vrcfown9-en/landscape/waiting-for-god-to-text-back-vrcfown9-1d26513c3498499dd96683b1dd770609.jpg

Ah, ok. That's a bit harder for us since our server never touches the files, they go straight to s3. As far as I can tell it is actually impossible to use query parameters to bust Imgix's cache. At least I only need this as a temporary transition and Imgix's url purging endpoint seems to be working well.

For anyone who might still be wondering about this issue/finding this over a year later, there are a few things I want to mention.
Although this might not have been the case when this issue was originally opened, in this project's latest release you can add the cache busting parameter in the following way:

client.path("/path/to/image.jpg").to_url({t:12345567})
# .../path/to/image.jpg?ixlib=rb-3.0.0&t=12345567

path() should only be passed the image path (everything before ?) while to_url() can be used to append any number of query parameters. This would avoid the double ? scenario, which can cause unexpected behavior on the imgix backend. Again, this behavior might not have always been the case. I also want to note that sometime in the future we will implement better path validation to avoid these types of scenarios.

Closing this issue now, but feel free to comment back with any questions.
