Hi @NobbZ, Thank you for your prompt response. I was able to validate this against a regex that checks for UUID v4 and I raised an appropriate error for invalid id’s.

I am a little confused with this binary_id type.
So what you are saying is that I need to do type validation before I can use it with Repo.get or any other action from Ecto or my application will blow up? Is that correct?

I like to use Ecto.UUID.cast(uuid) (rather than using regexes or whatever) to test if it’s a valid UUID before handing it to Repo.get or the like. If it’s not valid then I return an {:error, :invalid_uuid} tuple from the context function then decide how to surface it to the user (or Rollbar or whatever) in the caller. This way the app doesn’t “blow up” but you can gracefully handle it.

Yes and no… The result of the query depends on how your database handles invalid input. But I think most databases error out on invalid input. Passing an ill-formed UUID is like passing a string when an integer is expected.
