Overview

Outputs a simple <label> with a HTML5 <input type="datetime-local"> (or <input type="datetime">) wrapped in the standard <li> wrapper. This is an alternative to :date_select for :date, :time, :datetime database columns. You can use this input with :as => :datetime_picker.

Please note: Formtastic only provides suitable markup for a date picker, but does not supply any additional CSS or Javascript to render calendar-style date pickers. Browsers that support this input type (such as Mobile Webkit and Opera on the desktop) will render a native widget. Browsers that don't will default to a plain text field<input type="text"> and can be poly-filled with some Javascript and a UI library of your choice.

Examples:

Full form context and output


<%= semantic_form_for(@post) do |f| %>
  <%= f.inputs do %>
    <%= f.input :publish_at, :as => :datetime_picker %>
  <% end %>
<% end %>

<form...>
  <fieldset>
    <ol>
      <li class="string">
        <label for="post_publish_at">First name</label>
        <input type="date" id="post_publish_at" name="post[publish_at]">
      </li>
    </ol>
  </fieldset>
</form>

Setting the size (defaults to 16 for YYYY-MM-DD HH:MM)

<%= f.input :publish_at, :as => :datetime_picker, :size => 20 %>
<%= f.input :publish_at, :as => :datetime_picker, :input_html => { :size => 20 } %>

Setting the maxlength (defaults to 16 for YYYY-MM-DD HH:MM)

<%= f.input :publish_at, :as => :datetime_picker, :maxlength => 20 %>
<%= f.input :publish_at, :as => :datetime_picker, :input_html => { :maxlength => 20 } %>

Setting the value (defaults to YYYY-MM-DD HH:MM for Date and Time objects, otherwise renders string)

<%= f.input :publish_at, :as => :datetime_picker, :input_html => { :value => "1970-01-01 00:00" } %>

Setting the step attribute (defaults to 1)

<%= f.input :publish_at, :as => :datetime_picker, :step => 60 %>
<%= f.input :publish_at, :as => :datetime_picker, :input_html => { :step => 60 } %>

Setting the step attribute with a macro

<%= f.input :publish_at, :as => :datetime_picker, :step => :second %>
<%= f.input :publish_at, :as => :datetime_picker, :step => :minute %>
<%= f.input :publish_at, :as => :datetime_picker, :step => :quarter_hour %>
<%= f.input :publish_at, :as => :datetime_picker, :step => :fifteen_minutes %>
<%= f.input :publish_at, :as => :datetime_picker, :step => :half_hour %>
<%= f.input :publish_at, :as => :datetime_picker, :step => :thirty_minutes %>
<%= f.input :publish_at, :as => :datetime_picker, :step => :hour %>
<%= f.input :publish_at, :as => :datetime_picker, :step => :sixty_minutes %>

Setting the min attribute

<%= f.input :publish_at, :as => :datetime_picker, :min => "2012-01-01 09:00" %>
<%= f.input :publish_at, :as => :datetime_picker, :input_html => { :min => "2012-01-01 09:00" } %>

Setting the max attribute

<%= f.input :publish_at, :as => :datetime_picker, :max => "2012-12-31 16:00" %>
<%= f.input :publish_at, :as => :datetime_picker, :input_html => { :max => "2012-12-31 16:00" } %>

Setting the placeholder attribute

<%= f.input :publish_at, :as => :datetime_picker, :placeholder => "YYYY-MM-DD HH:MM" %>
<%= f.input :publish_at, :as => :datetime_picker, :input_html => { :placeholder => "YYYY-MM-DD HH:MM" } %>

Using datetime (UTC) or datetime-local with :local (defaults to true, datetime-local input)

<%= f.input :publish_at, :as => :datetime_picker, :local => false %>
