# My AvatarUploader # Override the storage directory: def storage_dir(_version, {_file, scope}) do "uploads/user/avatars/#{scope.id}" end # My User schema use Waffle.Ecto.Schema schema "users" do field :avatar, Allychat.Uploaders.AvatarUploader.Type field :email, :string field :password, :string, virtual: true, redact: true field :hashed_password, :string, redact: true field :confirmed_at, :naive_datetime timestamps() end def avatar_changeset(user, attrs) do user |> cast(attrs, [:avatar]) |> cast_attachments(attrs, [:avatar]) |> validate_required([:avatar]) end # My Accounts context def change_user_avatar(user, attrs \\ %{}) do User.avatar_changeset(user, attrs) end def update_user_avatar(user, attrs) do changeset = user |> User.avatar_changeset(attrs) Ecto.Multi.new() |> Ecto.Multi.update(:user, changeset) |> Repo.transaction() |> case do {:ok, %{user: user}} -> {:ok, user} {:error, :user, changeset, _} -> {:error, changeset} end end When I do this, it tells me that it can’t find id in nil. I tried a lot of options, also the one from waffle_ecto docs, and still couldn’t find an answer on how to upload an image to the storage_dir.
Does anyone know what I can do to fix this? I’m pretty new to Waffle
