Question

In my header, users can add an “item” via a form. I want this option to be available on each page, so I have in my header :

<%= form_for(@item) do |f| %>

           <div>
              <div class="title"><%= f.label :name, "Name" %></div>
              <div class="champ"><%= f.text_field :name %></div>
          </div>

          <div>
              <%= f.submit "add this item" %>
          </div>
<% end %>

But it forces me to add this in each controller :

def action
    @item = Item.new
end

How can I avoid it ? Using Application controller ?

Thanks !

Answer 1

Define a method in application controller and use before_filter.

class ApplicationController < ActionController::Base
  ..
  before_filter :initialize_item

  def initialize_item
    @item = Item.new
  end
end

initialize_item method will be executed on each request now.
