You shouldn't have to repeat yourself when writing labels for things: currently you need to do:

  <% form_for(:post, ...) do |f| %>
    Title
    <%= f.text_field(:title) %>
    Body
    <%= f.text_area(:body) %>
  <% end %>

Whereas I'd rather not repeat myself over and over...

  <% form_for(:post, ...) do |f| %>
    <%= f.label(:title) %>
    <%= f.text_field(:title) %>
    <%= f.label(:body) %>
    <%= f.text_area(:body) %>
  <% end %>

This plugin lets you do this by adding a +label+ method to ActionView::Helpers::FormHelper. You can also use the +FormBuilder+ style as shown above. See the docs for that module for more details.

There is currently no advanced documentation for this plugin.
