I’m trying to show a navigation bar if the user is signed in.

In my application.html.erb I have the line
<% if signed_in? %> – which is causing the error:

NoMethodError in Static_pages#home

undefined method '[]' for nil:NilClass

Extracted source (around line #16):

13:   </head>
14:   <body>
15: 
16:     <% if signed_in? %>
17:      <div class="navbar navbar-fixed-top">
18:       <div class="navbar-inner">
19:         <div class="container">`

Here is my SessionsHelper:

def sign_in(user)
    cookies.permanent[:remember_token] = user.remember_token
    self.current_user = user
end

def signed_in?
    !current_user.nil?
end

def current_user=(user)
    @current_user = user
end

def current_user
    puts 'current_user called'
    @current_user ||= User.find_by_remember_token(cookies.permanent[:remember_token])
end

def sign_out
    self.current_user = nil
    cookies.delete(:remember_token)
end

My ApplicationController:

class ApplicationController < ActionController::Base
  protect_from_forgery
  include SessionsHelper
end

I can’t seem to figure out why !current_user.nil? is breaking the page. When I comment out !current_user.nil? in the signed_in? method can get called without breaking the page. But I obviously don’t get the signed_in value I was hoping for.

    exception was raised here: cookies.permanent[:remember_token]

    so, cookies.permanent is nil

    —- EDITED

    got it,

    use cookies.permanent[:remember_token] = only for writing, but read it as cookies[:remember_token]
