我有这个模板

  <%= form_for @changeset, bid_path(@conn, :update, 1), [method: :put], fn f -> %>
    <% 
      require IEx
      IEx.pry
    %>
<%= if @changeset.action do %>
  <div class="alert alert-danger">
    <p>Oops, something went wrong! Please check the errors below.</p>
  </div>
<% end %>

如何在IEx控制台中显示@changeset？当我试图这样做时,会出现错误:

pry(5)> @changeset
** (ArgumentError) cannot invoke @/1 outside module
    (elixir) lib/kernel.ex:3960: Kernel.assert_module_scope/3
