+ # <% form_for(@post) do |f| %>
+ # ...

+ # <% form_for(@post, :url => super_post_path(@post)) do |f| %>

+ #
+ # === Customized form builders

# You can also build forms using a customized FormBuilder class. Subclass FormBuilder and override or define some more helpers,
# then use your custom builder. For example, let's say you made a helper to automatically add labels to form inputs.
