Defined in:

Overview

Outputs a simple <label> with a <input type="file"> wrapped in the standard <li> wrapper. This is the default input choice for objects with attributes that appear to be for file uploads, by detecting some common method names used by popular file upload libraries such as Paperclip and CarrierWave. You can add to or alter these method names through the file_methods config, but can be applied to any input with :as => :file.

Don't forget to set the multipart attribute in your <form> tag!

Examples:

Full form context and output

<%= semantic_form_for(@user, :html => { :multipart => true }) do |f| %>
  <%= f.inputs do %>
    <%= f.input :avatar, :as => :file %>
  <% end %>
<% end %>

<form...>
  <fieldset>
    <ol>
      <li class="file">
        <label for="user_avatar">Avatar</label>
        <input type="file" id="user_avatar" name="user[avatar]">
      </li>
    </ol>
  </fieldset>
</form>
