How to use Exquisite selector? about amnesia

[cjimison]

This is kind of an old question but I figured I would give it a response just because I hit a similar issue.

Try changing it to

      existing_user = User.where(email == new_mail, select: id)
      existing_user  |> Amnesia.Selection.values

I think exquisite is doing some macro programming funness and gets confused when you try to pipe or do other operations besides just the "where" call.

For me it worked when I added require statement:

  require Amnesia
  require Database.User
  require Exquisite
