ActionView::Helpers::FormHelper

I just learned you can provide Label text for fields in your locale files with #RubyOnRails. Huge time & key saver.

Returns a label tag tailored for labelling an input field for a specified attribute (identified by method ) on an object assigned to the template (identified by object ). The text of label will default to the attribute name unless a translation is found in the current I18n locale (through helpers.label.<modelname>.<attribute>) or you specify it explicitly. Additional options on the label tag can be passed as a hash with options . These options will be tagged onto the HTML as an HTML element attribute as in the example shown, except for the :value option, which is designed to target labels for #radio_button tags (where the value is used in the ID of the input tag).
