#labeled_input(object_name, method, options = {}, &block) ⇒ Object

Returns a <div> containing a label, an input, and an option comment block, pre-styled in LRD style.

pass :label => false to suppress the label text. (A label tag is still emitted.) pass :required => true to dispay as a required field (class required set on both the div and the input) pass :text => “foo” to override the label text pass :divclass => ‘foo’ to add ‘foo’ to the CSS class of the <div> pass :comment => “text” to append a span.comment with text after the input pass :type => ‘password’ } to use a password_field instead of a text_field

(also supported: text, passsword, hidden, file, text_area, search, telephone, url
 email, range, submit)

Examples (in HAML):

- form_for(@user) do
  = f.labeled_input(:login)
# => <div class='labeled_input'>
# =>   <label for='user_login'>login</label>
# =>   <input type='text' name='user[login]' id='user_login' value="#{@user.login}" />
# => </div>
