wie kann ich einstellen, dass session-setup, wenn ich test-phoenix-Aktion, die brauchen user_id in der session?

Habe ich eine Prüfung, die müssen user_id Sitzung vor der Prüfung, weil diese Aktion kennen müssen, um current_user.

setup do
  %User{
    id: 123456,
    username: "lcp",
    email: "[email protected]",
    password: Comeonin.Bcrypt.hashpwsalt("password")
  } |> Repo.insert

  {:ok, user: Repo.get(User, 123456) }
end

test "POST /posts", context do
  # conn = conn()
  #      |> put_session(:user_id, context[:user].id)
  #      |> post("/posts", %{ post: %{ title: "title", body: "body" } })

  # assert get_flash(conn, :info) == "Post created successfully."

  # updated to => 
  conn = conn()
        |> Map.put(:secret_key_base, String.duplicate("abcdefgh", 8))
        |> Plug.Session.call(@session)
        |> Plug.Conn.fetch_session
        |> put_session(:user_id, context[:user].id)
        |> post("/posts", %{ post: %{ title: "title", body: "body" } })

  assert get_flash(conn, :info) == "Post created successfully."
end

Ich versuchte diesen code, aber es sagt, dass session not fetched, call fetch_session/2.

web/Controller/controller_helper.ex

defmodule SimpleBlog.ControllerHelpers do    
  alias Phoenix.Controller
  alias Plug.Conn
  alias SimpleBlog.Router.Helpers

  def authenticate(conn, _) do
    case Conn.get_session(conn, :user_id) do
      nil ->
        unauthorized(conn)
      user_id ->
        case SimpleBlog.Repo.get(SimpleBlog.User, user_id) do
          {:ok, user} ->
            Conn.assign(conn, :current_user, user)
          nil ->
            unauthorized(conn)
        end
    end
  end

  def unauthorized(conn) do
    conn
      |> Controller.put_flash(:error, "You must be logged in")
      |> Controller.redirect(to: Helpers.session_path(conn, :new))
      |> Conn.halt
  end
end

Aktualisiert

Bekomme ich null, wenn ich user_id aus der session durch Conn.get_session(conn, :user_id).

Hier ist die post controller
web/Controller/post_controller.ex

defmodule SimpleBlog.PostController do
  use SimpleBlog.Web, :controller
  import SimpleBlog.ControllerHelpers

  alias SimpleBlog.Post

  plug :authenticate when not action in [:new]

  def create(conn, %{ "post" => post_params }) do
    changeset = Post.changeset(%Post{}, post_params)

    case Repo.insert(changeset) do
      {:ok, _post} ->
        conn
          |> put_flash(:info, "Post created successfully.")
          |> redirect(to: post_path(conn, :new))
      {:error, changeset} ->
        render(conn, "new.html", changeset: changeset)
    end
  end
end

Es ist meine test-Datei.

defmodule SimpleBlog.PostControllerTest do
  use SimpleBlog.ConnCase
  alias SimpleBlog.Repo
  alias SimpleBlog.User

  @session Plug.Session.init(
    store: :cookie,
    key: "_app",
    encryption_salt: "yadayada",
    signing_salt: "yadayada"
  )

  setup do
    %User{
      id: 123456,
      username: "lcp",
      email: "[email protected]",
      password: Comeonin.Bcrypt.hashpwsalt("password")
    } |> Repo.insert

    {:ok, user: Repo.get(User, 123456) }
  end


  @tag timeout: 900000
  test "POST /posts", context do
    conn = conn()
            |> Map.put(:secret_key_base, String.duplicate("abcdefgh", 8))
            |> Plug.Session.call(@session)
            |> Plug.Conn.fetch_session
            |> put_session(:user_id, context[:user].id)
            |> post("/posts", %{ post: %{ title: "title", body: "body" } })

    assert get_flash(conn, :info) == "Post created successfully."
  end
end

lib/simple_blog/Stecker/authentifiziert.ex

Definiere ich ein Plugin authentifiziert

defmodule SimpleBlog.Plugs.Authenticated do
  import Plug.Conn
  alias Phoenix.Controller
  alias SimpleBlog.Router.Helpers
  alias SimpleBlog.User

  def init(options) do
    options
  end

  def call(conn, _) do
    case conn |> current_user_id do
      nil ->
        conn
          |> Controller.put_flash(:error, "You must be logged in")
          |> Controller.redirect(to: Helpers.session_path(conn, :new))
          |> halt
      current_user_id ->
        conn |> assign(:current_user, SimpleBlog.Repo.get(User, current_user_id))
    end
  end

  defp current_user_id(conn) do
    case Mix.env do
      :test ->
        conn.private[:authenticated_current_user_id]
      _ ->
        conn |> fetch_session |> get_session(:current_user_id)
    end
  end
end

in meinem test

conn = conn()
        |> put_private(:authenticated_current_user_id, context[:user].id)
        |> post("/posts", %{ post: %{ title: "title", body: "body" } })

assert get_flash(conn, :info) == "Post created successfully."

nun, der test ist bestanden.
