42. HW-part 1: Migration: Add another column called "credit_card" to the users table as following as part of ActiveRecord_Creation project. (Or you can create a new project and new database. I will call the new project as MyActiveRecord here.) The type of credit_card field is string. (4/21/09: done, HINT ON PAGE 76) OUTPUT: (in C:/cygwin/home/jasnow/RAILSPASSION/ActiveRecord_Creation)

    == 20090421162301 AddCreditCxard: migrated (0.1933s) ==========================
    
43. HW9-part 2: Validation: Add the following validation logic for the credit_card field.
    
1. It has to be unique.
2. User can enter the credit card format in the following format. The x has to be numeric value.
   
1. xxxx-xxxx-xxxx-xxxx (format #1)
   
2. xxxx xxxx xxxx xxxx (format #2)
   
3. xxxxxxxxxxxxxxxx (format #3) NOTE: 16 digits
   
44. HW9-part3: Callbacks: Use callbacks - before_save and before_create - to convert the format #1 and format #2 to format #3 meaning the actual table contains only format #3. (4/21/09: done, HINT ON PAGE 108) Loading development environment (Rails 2.1.0)

Week 6: Rails Passion Course - On My New Mac

1. Repeated Week 6 Homework (HW6) on my new White Mac Laptop.
2. (AL#1) Creating new project: studentapp in /Users/whitemac/NetBeansProjects directory using "Built-in JRuby 1.1.4" and "Glassfish V3".
   
3. Note the Mac experience is different from PC. Asked for Database Configurations/Accepted defaults/Continued.
   
4. Then went to "Install Rails" and I selected "Update JRuby OpenSSL Support" and it worked. Then I selected "Update Rails" (from 2.1.0) to 2.3.2.
5. Then I SKIPPED "Install Warbler" for now.
6. Selected "Finished" and it failed and asked for run "sudo gem update --system" so I did. After the "gem update" finished, I selected "OK" and it finished creating the Rails Project.
7. NOTE: Appears that MySQL is not installed on MAC, so going back to AL#0 to install MySQL on the MAC.
8. THURSDAY (Next Day): Found another article (http://sheldonconaty.com/?p=7) and followed it to use this article: http://www.hennessynet.com/blog/?p=40 about setting up .bash_profile and macports and mySQL.
