    <p>I implemented a shopping cart into my app.</p> <p>In my <code>ApplicationController.rb</code>, I have this:</p> <pre><code>before_filter :initialize_cart def initialize_cart if session[:cart_id] @cart = Cart.find(session[:cart_id]) else @cart = Cart.create session[:cart_id] = @cart.id end end </code></pre> <p>I am using Devise, and have enabled <code>:timeoutable</code>.</p> <p>These are the configs in my <code>config/initializers/devise.rb</code>:</p> <pre><code> # ==&gt; Configuration for :timeoutable # The time you want to timeout the user session without activity. After this # time the user will be asked for credentials again. Default is 30 minutes. config.timeout_in = 30.minutes # If true, expires auth token on session timeout. config.expire_auth_token_on_timeout = true </code></pre> <p>The issue is that I occasionally want to sweep old carts. As it stands right now, once a cart hasn't been accessed in a while it gets deleted.</p> <p>However, when the user tries to login - if they haven't cleared cookies in a while - they get this error:</p> <pre><code>ActiveRecord::RecordNotFound at / Couldn't find Cart with id=51 </code></pre> <p>I checked the session object for a timestamp of creation or update and it doesn't have one - so I can't check the state of the session and delete the session if it is past 30 minutes or whatever.</p> <p>This is what the session object looks like:</p> <pre><code>&gt;&gt; session =&gt; {"session_id"=&gt;"57bkhjadksjfhaksjdhfca", "cart_id"=&gt;51, "_csrf_token"=&gt;"3823j42&amp;*&amp;@#lkjM+wKkagdabskdjfhba="} </code></pre> <p>How do I either check to see the if the session is recent (say the user - both logged in and non-logged in - has done something in the last hour) and then destroy it if it isn't?</p> <p>Or how do I fix this issue in any other way?</p>

    1. COmaybe add your own `modified` param to the cart when it's created and then see when it was last modified (created or updated)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
