Overview

TODO:

Rename/Alias to NumberInput

Outputs a simple ‘<label>` with a HTML5 `<input type=“number”>` wrapped in the standard `<li>` wrapper. This is the default input choice for all database columns of the type `:float` and `:decimal`, as well as `:integer` columns that aren’t used for ‘belongs_to` associations, but can be applied to any text-like input with `:as => :number`.

Examples:

Full form context and output

<%= semantic_form_for(@user) do |f| %>
  <%= f.inputs do %>
    <%= f.input :shoe_size, :as => :number %>
  <% end %>
<% end %>

<form...>
  <fieldset>
    <ol>
      <li class="numeric">
        <label for="user_shoe_size">Shoe size</label>
        <input type="number" id="user_shoe_size" name="user[shoe_size]">
      </li>
    </ol>
  </fieldset>
</form>

Default HTML5 min/max/step attributes are detected from the numericality validations

class Person < ActiveRecord::Base
  validates_numericality_of :age, 
    :less_than => 100, 
    :greater_than => 17, 
    :only_integer => true
end

<%= f.input :age, :as => :number %>

<li class="numeric">
  <label for="persom_age">Age</label>
  <input type="number" id="person_age" name="person[age]" min="18" max="99" step="1">
</li>

Pass attributes down to the ‘<input>` tag

<%= f.input :shoe_size, :as => :number, :input_html => { :min => 3, :max => 15, :step => 1, :class => "special" } %>
