protocol Ecto.Queryable not implemented for

Question

I'm trying to implement Guardian into my API and perform a login through it to get JWT back. The tutorial I'm looking at is here. The problem is implementing the login using a User Model similar to what they're using in the example. The Model code looks like:

defmodule PushflightServer.User do
  use PushflightServer.Web, :model

use Ecto.Repo
import Ecto.Query
  alias PushflightServer.Repo

  schema "users" do
    field :name, :string
    field :email, :string
    field :encrypted_password, :string
    field :password, :string, virtual: true
    field :verify_token, :string
    field :verify_date, Ecto.DateTime

    timestamps
  end

  def from_email(nil), do: { :error, :not_found }
  def from_email(email) do
    IO.write("Before email")
    IO.inspect(email)
    Repo.one(User, email: email)
  end

If I call the from_email either from within Phoenix or straight in iex -S mix, I get the following error:

user = PushflightServer.User.from_email("[email protected]")

** (Protocol.UndefinedError) protocol Ecto.Queryable not implemented for User, the given module does not exist (ecto) lib/ecto/queryable.ex:33: Ecto.Queryable.Atom.to_query/1 (ecto) lib/ecto/repo/queryable.ex:90: Ecto.Repo.Queryable.execute/5 (ecto) lib/ecto/repo/queryable.ex:15: Ecto.Repo.Queryable.all/4 (ecto) lib/ecto/repo/queryable.ex:44: Ecto.Repo.Queryable.one/4

I must be missing something simple, but I haven't been able to find any documentation about why this is happening. The insert of the data using the Repo worked fine. Any ideas?

Answer 1

You need to fully namespace User as PushflightServer.User or you can use the shortcut __MODULE__

Answer 2

you should reference the modules with namespaces

  def from_email(email) do
    PushflightServer.one(PushflightServer.User, email: email)
  end
