    <p>I have implemented a facebook connect for my application. So when a user logs in I wish to store his facebook id in the session and use it across multiple controllers and views. I tried implementing this . I also referred to several similar questions answered in stackoverflow . However something seems wrong. I set the facebook id in the session in the UserController . I am not able to access it in the EventsController.</p> <p>The flow is : When the user logins in for the first time . The fbinsertupdate is called. And then the page redirects to events#index page.</p> <pre><code>class User &lt; ActiveRecord::Base def self.current=(u) @current_user = u end def self.current @current_user end end class ApplicationController &lt; ActionController::Base protect_from_forgery # Finds the User with the ID stored in the session with the key # :fb_user_id def current_user User.current ||= session[:fb_user_id] &amp;&amp; User.find(session[:fb_user_id]) end end class UsersController &lt; ApplicationController def fbinsertupdate #Facebook connect. Insert new user or update existing user @user = User.find_or_create_by_fbid(params[:fbid]) @user.update_attributes(params[:user]) session[:fb_user_id] = @user.fbid # storing the facebook id in the session render :nothing =&gt; true end end class EventsController &lt; ApplicationController def index @events = Event.all @current_user= User.current logger.debug "The current user is "+@current_user.name # This fails . Says the class in nil respond_to do |format| format.html # index.html.erb format.xml { render :xml =&gt; @events } end end end </code></pre>

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.
