Edge Rails now comes with a helper for creating form labels, so in your views, instead of doing this:

<% form_for(:user, @user, :url => user_path(@user)) do |f| -%>
<label for="user_login">Login</label>
<%= f.text_field :login %>

where the <label> is given a for attribute of user_login (since the convention for form input ids is {MODEL_NAME}_{ATTRIBUTE_NAME}), you can instead now do:

<%= label(:user, :login) %>

Quite a bit neater. Makes it easier to explain to beginners how they should use <label>s appropriately since the syntax is similar to the other form helpers. Now give your <label>s proper for attributes if you're not doing so already.

This makes plugins like this form label helper plugin obsolete.
