Question

我正在为ex_admin实施身份验证，是否应该为登录页面做自己的自定义UI？

我使用以下视图进行工作

<h2>Login Page</h2>
  <%= form_for @changeset, @action, fn f -> %>    
    <div class="form-group">
      <%= label f, :username, class: "control-label" %>
      <%= text_input f, :email, class: "form-control" %>
      <%= error_tag f, :email %>
    </div>
    <div class="form-group">
      <%= label f, :password, class: "control-label" %>
      <%= password_input f, :password, class: "form-control" %>
      <%= error_tag f, :password %>
    </div>
    <div class="form-group">
      <%= submit "Submit", class: "btn btn-primary" %>
    </div>
  <% end %>

我的控制器看起来像这样

defmodule CanvasPostWeb.SessionController do
    use CanvasPostWeb, :controller
    alias CanvasPostWeb.Router.Helpers
    alias CanvasPost.Auth
    alias CanvasPost.Auth.Verify

    def current_user(conn) do
        Auth.Guardian.Plug.current_resource(conn)
    end

    def index(conn, params) do
        changeset = Auth.change_user(%Auth.User{})
        maybe_user = Guardian.Plug.current_resource(conn)
        conn
          |> render("session.html", changeset: changeset, action: session_path(conn, :login))
    end

    def login(conn, %{"user" => %{"email" => email, "password" => password}}) do
        Verify.authenticate_user(email, password)
          |> login_reply(conn)
      end

    defp login_reply({:error, error}, conn) do
        conn
        |> put_flash(:error, error)
        |> redirect(to: "/")
      end

      defp login_reply({:ok, user}, conn) do
        conn
        |> put_flash(:success, "Welcome back!")
        |> Auth.Guardian.Plug.sign_in(user)
        |> redirect(to: "/admin")
    end

    def logout(conn, _) do
        conn
        |> Auth.Guardian.Plug.sign_out
        |> put_flash(:info, "You have been logged out")
        |> redirect(to: session_path(conn, :index))
      end
  end

添加exadmin auth实现时，哪种身份验证工作正常

defimpl ExAdmin.Authentication, for: Plug.Conn do
  alias CanvasPostWeb.Router.Helpers
  alias CanvasPost.ExAdmin.Auth


  def use_authentication?(_), do: true
  def current_user(conn), do: CanvasPostWeb.SessionController.current_user(conn)
  def current_user_name(conn), do: CanvasPostWeb.SessionController.current_user(conn).email
  def session_path(conn, action), do: Helpers.session_path(conn, :index)
  def session_path(conn, :destroy), do: Helpers.session_path(conn, :delete, 0)

end

但这是使用ex_admin实现身份验证的正确方法。在Wiki中链接的contacts_demo中，还有一个自定义UI登录页面。但是当我查看css文件时，我看到它们包含登录表单的样式。在ex_admin中没有用于身份验证的UI是否正确？
