    <p>I have currently set my app so that on successful sign in the app redirects the user to their profile at <code>localhost:3000/users/id</code> however if I am the first user <code>id =&gt; 1</code> and type <code>users/2</code> I have full access to this profile. I have been trying to find how to stop this using devise. I'm pretty new to rails so I'm sure I'm missing something simple, I have used the <code>before_filter :authenticate_user!</code> but this is obviously just checking if a user is signed in, but doesn't limit access to other users' profiles. I have read a bit on CanCan but this seems a bit overkill for what I am trying to achieve. Any pointers much appreciated. </p> <p>users_controller.rb</p> <pre><code>class UsersController &lt; ApplicationController before_filter :authenticate_user! before_filter :user_authorization def index @users = User.all end def show @user = User.find(current_user[:id]) end private def user_authorization redirect_to(root_url) unless current_user.id == params[:id] end end </code></pre> <p>This is being reported from the server:</p> <pre><code>Started GET "/users/2" for 127.0.0.1 at 2012-06-24 13:00:38 +0200 Processing by UsersController#show as HTML Parameters: {"id"=&gt;"2"} User Load (0.1ms) SELECT "users".* FROM "users" WHERE "users"."id" = 2 LIMIT 1 User Load (0.2ms) SELECT "users".* FROM "users" WHERE "users"."id" = ?

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.
