I'm trying to display a form on the screen. But I keep getting this error when I try to start the server. `locations_controller.ex ==
** (CompileError) web/controllers/locations_controller.ex:5: Locations.__struct__/1 is undefined, cannot expand struct Locations`. BTW I'm new to elixir so I'm probably doing something really obvious wrong.

Here is my code:

locations.controller.ex
-----------------------

```
 def new(conn, _params) do
    changeset = Locations.changeset(%Locations{})

    render conn, "new.html", changeset: changeset
  end

  def create(conn, %{"locations" => %{ "start" => start, "end" => finish }}) do
    changeset = %AwesomeLunch.Locations{start: start, end: finish}
    Repo.insert(changeset)

    redirect conn, to: locations_path(conn, :index)
  end

```

VIEW
----

```html
<h1>Hey There</h1>

<%= form_for @changeset, locations_path(@conn, :create), fn f -> %>

  <label>
    Start: <%= text_input f, :start %>
  </label>

  <label>
    End: <%= text_input f, :end %>
  </label>

  <%= submit "Pick An Awesome Lunch" %>

<% end %>

```

model
-----

```html
    defmodule AwesomeLunch.Locations do
  use AwesomeLunch.Web, :model

  use Ecto.Schema
  import Ecto.Changeset

  schema "locations" do
    field :start
    field :end
  end

  def changeset(struct, params \\ %{}) do
    struct
    |> cast(params, [:start, :end])
    |> validate_required([:start, :end])
  end
end

```

Like I said I'm getting this error:

```html
    locations_controller.ex ==
** (CompileError) web/controllers/locations_controller.ex:5: Locations.__struct__/1 is undefined, cannot expand struct Locations

```
