Awesome! You have no idea how much your video content has come to my rescue! Your explanation of active storage with Amazon S3 was top-notch and incredibly helpful. Thank you so much!

When I click EDIT, the previously save image goes away. How can I prevent this from being removed?

[@LibertarianSeeker]

Great series! Thanks so much!

And about variants URL? Can I create a variant versions in this setup? How can I offer a s3 direct link for variants?

Hello and thanks for the video! Question: Where all the other files of your database are stored. Like the text of the posts not only the images or users data?

[@GorailsTV]

Depends on your database but they will always store it on disk in the databases data directory.

[@paulthemrgreen]

So, do you need another s3 bucket for example users credentials or they stored in a postgres database?

[@paulthemrgreen]

Hey go rails! I have a question If I use action text for some blog post. Since these blog posts are not many can instead of uploading files in Amazon s3, I can store them in my app? Thanks!!

[@GorailsTV]

You can use the file store but your hosting service would need persistent disk storage in production. So a place like Heroku wouldn't work because they run everything in containers but a hosting service like Hatchbox.io that we run does support persistent disk storage.

This was what i was looking for, thank you! I’m using rails as a backend and returning a link to my images to render in my react app. What’s the correct way to get the s3 url? I originally used rails_blob_path when everything was local, but I believe object.image.url is the way to get the s3 link. But I saw someone say that the predecessor to this, object.image.service_url was frowned upon. Is that still the case?

Hi! I am really enjoying your series so far. When I upload an image while editing a blog post, the image shows. When I update the blog post, the image doesn't show. Looking into the console, I am getting the following error" "ActiveStorage::Representations::RedirectController#show wrong number of arguments(given 1, expected 0) ". I made sure I had vips installed and tried installing different versions of image_processing (where the error comes from) and nothing has worked so far. Any help would be appreciated and thanks!

[@GorailsTV]

That's a good question. Share the full stacktrace if you get a chance.

If my app is to have users, and users uploading images under their account AND only owner of images can access/view the images - Will the ACL be disalbed?

[@GorailsTV]

Leave them as private.

My god it’s Litteraly a hell storm just to connect the app to the damn bucket so frustrating

[@GorailsTV]

Good old Amazon for you!

[@Mw-od6sd]

Hey I actually went through it slowly and finally got my rails app connected to the bucket . THANK YOU !

[@Mw-od6sd]

But I need your help really badly I am having serious trouble now

[@Mw-od6sd]

I tried sending the urls back to the frontend . And it’s not recognizing them and it’s crashing on frontend. I used rails_blob_path , rails_blob_url and more with disposition: “attached” Only sending the service url works but then it won’t download when plugged into the href (I have download attribute in href tag ) HELP PLEASE !!!
