Hello one and all, I am trying to create a full stack app with react and phoenix from an article that uses phoenix 1.3 while I’m using the latest version 1.5.7. in the article, the models db access is used and version 1.5.7 no longer uses the models so my app gives me the following error when I send a get request from postman0

 function Repo.all/1 is undefined (module Repo is not available)

The controller file

defmodule PhxReactList7Web.BlogsController do

  use PhxReactList7Web, :controller

  alias PhxReactList7.Blogs

  def index(conn, _params) do

    blogs = Repo.all(Blogs)

    render conn, "index.json", blogs: blogs

  end

end

the repo file

defmodule PhxReactList7.Repo do

  use Ecto.Repo,

    otp_app: :phx_react_list_7,

    adapter: Ecto.Adapters.Postgres

end

the blogs file

defmodule PhxReactList7.Blogs do

  import Ecto.Query, warn: false

end
