You may recall from Section 442 that Ruby lets you add methods to any class, even built-in ones In that section, we added a palindrome method to the String class (and discovered as a result that "deified" is a palindrome), and we also saw how Rails adds a blank method to class Object (so that ""blank , " "blank , and nilblank are all true) The cookie code in Listing 912 (which internally sets a cookie that expires 20yearsfrom_now) shows yet another example of this practice, through one of Rails time helpers, which are methods added to Fixnum (the base class for numbers):

These are useful for upload validations, making it easy to restrict, say, image uploads to 5megabytes Though it must be used with caution, the flexibility to add methods to built-in classes allows for extraordinarily natural additions to plain Ruby Indeed, much of the elegance of Rails ultimately derives from the malleability of the underlying Ruby language
UPCA Drawer In Java

Unfortunately, using the user id in this manner is insecure for the same reason discussed in Box 92: a malicious user could simulate a cookie with the given id, thereby allowing access to any user in the system The traditional solution before Rails 3 was to create a secure remember token associated with the User model to be used in place of the user id (see, eg, the Rails 23 version of Rails Tutorial ) This pattern became so common that Rails 3 now implements it for us using cookiespermanentsigned:

The assignment value on the right-hand side is an array consisting of a unique identifier (ie, the user s id) and a secure value used to create a digital signature to prevent the kind of attacks described in Section 72 In particular, since we went to the trouble of creating a secure salt in Section 723, we can re-use that value here to sign the remember token Under the hood, using permanent causes Rails to set the expiration to 20yearsfrom_now, and signed makes the cookie secure, so that the user s id is never exposed in the browser (We ll see how to retrieve the user using the remember token in Section 933) The code above shows the importance of using new_record in Listing 710 to save the salt only upon user creation Otherwise, the salt would change each time the user was saved, preventing the retrieval of the session s user in Section 933

In this section, we ll learn how to get and set the session s current user Let s look again at the sign_in function to see where we are:

The purpose of this line is to create current_user, accessible in both controllers and views, which will allow constructions such as

<%= current_username %>
redirect_to current_user
The principal goal of this section is to define current_user To describe the behavior of the remaining signin machinery, we ll first fill in the test for signing a user in (Listing 913)
Listing 913 Filling in the test for signing the user in
spec/controllers/sessions_controller_specrb
describe SessionsController do describe "POST 'create'" do
describe "with valid email and password" do
9: Sign In, Sign Out
before(:each) do @user = Factory(:user) @attr = { :email => @useremail, :password => @userpassword } end it "should sign the user in" do post :create, :session => @attr controllercurrent_usershould == @user controllershould be_signed_in end it "should redirect to the user show page" do post :create, :session => @attr responseshould redirect_to(user_path(@user)) end end end end
The new test uses the controller variable (which is available inside Rails tests) to check that the current_user variable is set to the signed-in user, and that the user is signed in:
it "should sign the user in" do post :create, :session => @attr controllercurrent_usershould == @user controllershould be_signed_in end
The second line may be a little confusing at this point, but you can guess based on the RSpec convention for boolean methods that
