Can't figure how to make this work with seeds.ex

[keslert]

I'm trying to populate my database with some fake data and I want it to point at a previously uploaded image, but I keep getting errors. What's the proper way to make this happen?

If you have an uploaded image on S3 which you want to reference directly, you should not use primary keys of the model to store the files, as these could change every time you seed. I would instead use a uuid as the filename / path.

Then, during the seed file, I would set the avatar attribute directly, rather than going through an upload process.

user = Repo.get! User, 1

user |> Ecto.Changeset.change(avatar: "ccfba165-aa01-4640-a2c7-a580a9a3bb4a.png?v=63620622730") |> Repo.update!

Did you find a different approach to take?

@stavro No such luck. I've just been skipping images for now. I tried your suggestion but I'm stil getting the following errors: https://gist.github.com/keslert/c93e46def689e79ca8d5.

I tried inserting the book by itself and then doing the update and it gives the same error. This is my BookImage implementation: https://gist.github.com/keslert/445671bf256622319f84

Sorry, try this:

book = Repo.get! Book, 1
book |> Ecto.Changeset.change(
  image: %{file_name: "tea_rex.jpeg", updated_at: Ecto.DateTime.utc}
) |> Repo.update!

Awesome, that did it. Thanks!
