And with form_for rails works out for you whether the form's action
should be the url for saving or updating the form etc.
It's true that
<%= start_form_tag ({:action => "at"}, {:method => "post"}) %>
<%= end_form_tag %>
is not very different from
<form action = "/look/at" method = "post"
</form>
but
<% form_for @person do |f| %>
<%= f.label :name %>: <%= f.text_field :name%>
<% end %>
is less cumbersome than the alternative.
