Ruby S3 URL helper


(Arran Scott) #1

Is there a way to get the URL on the Ruby side for the files uploaded to S3?

I have a partial that I’m pulling in with ajax that loops through a load of filenames, something like the following.

filenames.each do |filename|
  <%= image_tag filename %>
end

The filename is an image that will show in a slideshow/carousel, these images are uploaded to S3 and I want to get the full path to each image on S3.

I’ve traced this through and have seen how this is done on the front-end in the Ember app but I specifically want to get this on the Ruby side.

Cheers

How are you generating filenames?


(Arran Scott) #3

filenames is a table, belonging to User.

The filenames table stores filenames for images uploaded to a users slideshow.

I’ve managed to solve this by adding an upload_id column to my table, and when creating the upload with Upload.create_for I set the upload_id manually in the filenames table. This way I can find the upload using the Upload.find_by method and get the URL for the upload.

Seems to work ok, happy to be told if there will be an issue doing it this way.

That’s the way to go :thumbsup:
