Using Barcode printer for Java Control to generate, create bar code image in Java applications.
In this chapter, we ve effectively finished the User model, so we re now fully prepared to sign up new users and to let them sign in securely with an email/password combination Moreover, we have a nice first cut of the user profile page, so after signing in users will have a place to go

Drawing GTIN - 12 In Java
Using Barcode maker for Java Control to generate, create UPCA image in Java applications.
Before moving on, we should close the Git loop opened in the introduction to 6 by making a final commit to the modeling-users branch and then merging into master26 First, verify that we are on the modeling-users branch:
ISBN - 13 Generator In Java
Using Barcode encoder for Java Control to generate, create Bookland EAN image in Java applications.
$ git branch master * modeling-users
GS1 - 13 Scanner In VS .NET
Using Barcode scanner for .NET Control to read, scan read, scan image in .NET framework applications.
As noted in Section 135, the asterisk here identifies the present branch, so we are indeed ready to commit and merge:27
Recognizing Data Matrix In .NET Framework

Using Barcode drawer for ASP.NET Control to generate, create UPC-A Supplement 2 image in ASP.NET applications.
26 Ordinarily, I recommend making more frequent, smaller commits, but frequent Git commits throughout the tutorial would be hard to maintain and would break up the flow of the discussion 27 If you re not on the right branch, run git checkout modeling-users before proceeding

742 Heroku Deploy
Data Matrix 2d Barcode Drawer In .NET
Using Barcode printer for ASP.NET Control to generate, create ECC200 image in ASP.NET applications.
If you ve deployed your sample application to Heroku, you can push it up at this point:
Code 128A Drawer In C#.NET
Using Barcode generation for VS .NET Control to generate, create Code 128 Code Set A image in .NET framework applications.
$ git push heroku
Then migrate the database on the remote server using the heroku command:
$ heroku rake db:migrate
Now if you want to create a sample user on Heroku, you can use the Heroku console:
$ heroku console >> Usercreate(:name => "Example User", :email => "user@examplecom", > :password => "foobar", :password_confirmation => "foobar")
75 Exercises
1 Copy each of the variants of the authenticate method from Listing 727 through Listing 731 into your User model, and verify that they are correct by running your test suite 2 The final authenticate example (Listing 731) is particularly challenging Experiment with the console to see if you can understand how it works 3 How could you get the Gravatar helper gravatar_for to work if our User model used email_address instead of email to represent email addresses
Listing 727 The authenticate method with User in place of self
def Userauthenticate(email, submitted_password) user = find_by_email(email) return nil if usernil return user if userhas_password (submitted_password) end
Exercises
Listing 728 The authenticate method with an explicit third return
def selfauthenticate(email, submitted_password) user = find_by_email(email) return nil if usernil return user if userhas_password (submitted_password) return nil end
Listing 729 The authenticate method using an if statement
def selfauthenticate(email, submitted_password) user = find_by_email(email) if usernil nil elsif userhas_password (submitted_password) user else nil end end
Listing 730 The authenticate method using an if statement and an implicit return
def selfauthenticate(email, submitted_password) user = find_by_email(email) if usernil nil elsif userhas_password (submitted_password) user end end
Listing 731 The authenticate method using the ternary operator
def selfauthenticate(email, submitted_password) user = find_by_email(email) user && userhas_password (submitted_password) user : nil end

Sign Up
Now that we have a working User model, it s time to add an ability few websites can live with out: letting users sign up for the site thus fulfilling the promise implicit in Section 53, User signup: A first step We ll use an HTML form to submit user signup information to our application in Section 81, which will then be used to create a new user and save its attributes to the database in Section 83 As usual, we ll write tests as we develop, and in Section 84 we ll use RSpec s support for web navigation syntax to write succinct and expressive integration tests Since we ll be creating a new user in this chapter, you might want to reset the database to clear out any users created at the console (eg, in Section 732), so that your results will match those shown in the tutorial You can do this as follows:
