28. Managing table relationships using Zend_Db http://kb.vteamslabs.com

29. 1. Defining Relationship Between Database Tables • In this case, we will take example of a simple CMS. • Have two tables page & node. • A page can have multiple nodes. • A Page can be parent to another page. http://kb.vteamslabs.com

30. 2. Creating Models for Tables http://kb.vteamslabs.com

31. 3. Defining Relationships for Models • Since pages table has a One-to-many Relationship with the content_nodestable, we need to do the following: • Model_Page: Tell Zend_Db_Table that the pages table is dependent on the content_nodes table. • Model_ContentNode: Tell Zend_Db_Table that the content_nodes table is related to the pages table, by doing the following: • Setting the related columns. • Adding reference table class (Model_Page). • Setting the referenced table columns. http://kb.vteamslabs.com

32. 4. ContentNode to Page Relationship • Add the following code to the application/models/ContentNode.php: http://kb.vteamslabs.com

33. 5. Page to Page Relationship • Add the following code to the application/models/Page.php: http://kb.vteamslabs.com

34. 6. Fetching Dependent Rows http://kb.vteamslabs.com

35. 7. Fetching Parent Rows http://kb.vteamslabs.com

36. HANDLING SECURITY IN ZEND FRAMEWORK http://kb.vteamslabs.com

37. Security in Zend Framework is done through: • Zend_Authsolely concerned with authenticating (and persisting) the application users. • Zend_Acl handles resources, roles (user roles), and which roles can access which resources. http://kb.vteamslabs.com

38. 1. Managing Users • Normally we have two user types in a CMS: • Users: These are registered users who don’t have admin privileges. • Administrators: These are the site managers who can access any area of the CMS. Fields for Users Table: • `id` • `username` • `password` • `first_name` • `last_name` • `role` http://kb.vteamslabs.com

39. 2. Creating User Model Class http://kb.vteamslabs.com

40. User Authentication using Zend_Auth http://kb.vteamslabs.com

41. LIST OF AVAILABLE ZEND_AUTH ADAPTERS • Some of the common Zend_Authadapters are: • Database table authentication. • Digest authentication. • LDAP authentication. • Open ID. Here, we will use Zend_Auth_Adapter_DbTable. http://kb.vteamslabs.com
