exfile.url and exfile.path links resolve in "file not found" [phoenix 1.3]

[Schultzer]

Hi I'm trying to use Exfile to serve some images in a phoenix project, but I'm heading some serious head blocks that i'm not sure how to solve. the path I'm getting for exfile.url or exfile.path serve me a link to a file not found

I'm seeding the file to the database like shown in #33 the db is MySQL

so my setup is as following:

defmodule Myapp.Repo.Migrations.CreateCities do
  use Ecto.Migration

  def change do
    create table(:cities) do
      add :name,                   :string, null: false
      add :country,                :string, size: 2, null: false
      add :image,                  :string

      timestamps()
    end
  end
end

defmodule Myapp.Web.City do
  use Ecto.Schema
  import Ecto.Changeset

  schema "cities" do
    field :name,                   :string, null: false
    field :country,                :string, size: 2, null: false
    field :image,                  Exfile.Ecto.File

    timestamps()
  end

  @required_fields ~w(name country image)

  def changeset(city, params \\ %{}) do
    city
    |> cast(params, @required_fields)
    |> validate_required([:name, :country])
  end

defmodule Myapp.Web.Router do
  use NomadRentalPhx.Web, :router

  forward "/attachments", Exfile.Router
...
end

config :exfile, Exfile,
secret: "secret string to generate the token used to authenticate requests",
backends: %{
  "store" => {Exfile.Backend.FileSystem,
    directory: Path.expand("priv/static/store/#{System.system_time}")
  },
  "cache" => {Exfile.Backend.FileSystem,
    directory: Path.expand("priv/static/cache/#{System.system_time}")
  }
}

defmodule Myapp.Web do
  def view do
    quote do
       import Exfile.Phoenix.Helpers
    end
  end
end

image: %Exfile.File{backend: %Exfile.Backend{backend_mod: Exfile.Backend.FileSystem,
    backend_name: "store",
    directory: "path/myapp/priv/static/store/1493794933541734000",
    hasher: Exfile.Hasher.Random, max_size: -1, meta: %{ttl: :infinity},
    postprocessors: [], preprocessors: []},

   id: "59b376925ac84cb5832c683b7fd1fcaa03f990fffea1a0d24dd9ab49dcbb",
   meta: %{}},
