What is the Rails3 equivalent for start_form_tag?

Newbie here ... I'm just worried that, clearly, an old rail book.

To create the form, they have the following code:

<%= start_form_tag(:action => 'create')%>

        <%= text_field(:album, :title) %><br />
        <%= text_field(:album, :artist) %><br />
        <%= text_field(:album, :genre) %><br />
        <%= datetime_select(:album, :release_date) %><br />

        <%= submit_tag("Create") %>

    <%= end_form_tag %>

What is the correct Rails3 syntax for this code?

Thank.

Quite a lot has changed since Rails 1, and I was really impressed by the people who are willing to spend time to sit down with Rails 3 and learn the differences (1). The community should welcome them and RTFM's are not helping. Here I think I can help.

I would write this in Rails 3:

<%= form_for(@album) do |f| %>
  <p>
    <%= f.label :title %>
    <%= f.text_field :title %>
  </p>

  <p>
    <%= f.label :artist %>
    <%= f.text_field :artist %>
  </p>

  <p>
    <%= f.label :genre %>
    <%= f.text_field :genre %>
  </p>

  <p>
    <%= f.label :release_date %>
    <%= f.datetime_select :release_date %>
  </p>

  <%= f.submit %>
<% end %>

Woah, so many changes! Where to begin? Top line, of course!
