Usage

Present attributes using the API in the example below. It can also generate a standard label value pair given an attribute name using the attribute method. Arbitrary strings can also be presented using the string method.

Here is a complete example using all possible options.

<ul class="list-unstyled">
  <%= attributes_for @company do |b| %>
    <li><%= b.attribute :name, icon: 'building-o' %></li>
    <li><%= b.phone :phone %></li>
    <li><%= b.phone :fax, icon: 'fax' %></li>
    <li><%= b.email :email %></li>
    <li><%= b.email :support_email %></li>
    <li><%= b.url :website, id: :site %></li>
    <li>
      <%= b.attribute(:user, icon: 'user') do %>
        <%= link_to @company.user_name, url_for(@company.user) %>
      <% end %>
    </li>
    <li><%= b.duration :duration %></li>
    <li><%= b.boolean :active %></li>
    <li><%= b.date :due_on %></li>
    <li><%= b.datetime :created_at, format: :long %></li>
    <li>
      <%= b.string "Label" do %>
        Content
      <% end %>
    </li>
  <% end %>
</ul>

Passing :label_html or :value_html to #attribute adds the given options to the label and value wrapper tags.

<ul class="list-unstyled">
  <%= attributes_for @product, defaults: { label_html: { class: 'label' } } do |b|
    <li><%= b.attribute :price, icon: 'money', value_html: { class: 'pull-right' } %></li>
  <% end %>
</ul>

Passing :defaults to attributes_for gives the option to all attributes. This option you can typically use when you want add styling to the label of each attribute.

<ul class="list-unstyled">
  <%= attributes_for @company, defaults: { label_html: { class: 'label' } } do |b| %>
    <li><%= b.attribute :name, icon: 'building-o' %></li>
  <% end %>
</ul>

attributes_for wraps labels and values in span tags by default. Passing :wrappers to attributes_for gives you the option to change the wrapper.

<ul class="list-unstyled">
  <%= attributes_for @company, wrappers: { label: 'strong' } do |b| %>
    <li><%= b.attribute :name, icon: 'building-o' %></li>
  <% end %>
</ul>

Passing :empty to attributes_for overrides the default empty value.

<dl>
  <%= attributes_for @company, wrappers: { label: 'dt', value: 'dd' }, empty: '-' do |b| %>
    <%= b.attribute :fax %>
  <% end %>
</dl>
