-<h1>Creating Active Record Classes</h1>

-

-<p>

-We need to create two <a href="http://www.pradosoft.com/demos/quickstart/?page=Database.ActiveRecord">Active Record</a> classes, <tt>UserRecord</tt> and <tt>PostRecord</tt>, to represent data records in the <tt>users</tt> and <tt>posts</tt> tables, respectively. Active Record classes must extend from the base class <tt>ActiveRecord</tt>, and must define property names that matches with the field names of the corresponding table.

-</p>

-

-<p>

-To better organize our directories, we create a new directory <tt>protected/database</tt> to hold the class files. We also modify our application configuration by inserting the following lines. It is equivalent to adding the directory <tt>protected/database</tt> to PHP include_path, which allows us to use the classes without explicitly including them.

-</p>

-

-<com:TTextHighlighter CssClass="source" Language="xml">

-<paths>

-  <using namespace="Application.database.*" />

-</paths>

-</com:TTextHighlighter>

-

-<p>

-Instead of writing the classes manually, we will use the <a href="http://www.pradosoft.com/demos/quickstart/?page=GettingStarted.CommandLine">PRADO command line tool</a> again to generate the classes for us.

-</p>

-

-<p>

-Under the <tt>blog</tt> directory, run the following command to enter into the interactive mode of the command line tool:

-</p>

-

-<com:TTextHighlighter CssClass="source cli" Language="text">

-php path/to/prado-cli.php shell .

-</com:TTextHighlighter>

-

-<p>

-We should see

-</p>

-

-<com:TTextHighlighter CssClass="source cli" Language="text">

-Command line tools for Prado 3.1.0.

-** Loaded PRADO appplication in directory "protected".

-(c) 2006, Jan Kneschke <jan@kneschke.de>

-

->> use '?' to open the inline help

-

->>

-</com:TTextHighlighter>

-

-<p>

-At the prompt, enter the following two commands to create <tt>UserRecord</tt> and <tt>PostRecord</tt> classes:

-</p>

-

-<com:TTextHighlighter CssClass="source cli" Language="text">

->> generate users Application.database.UserRecord

-

->> generate posts Application.database.PostRecord

-</com:TTextHighlighter>

-

-<p>

-Here we used the <a href="http://www.pradosoft.com/demos/quickstart/?page=Fundamentals.Components">namespace format</a> again to specify the classes to be created. The path <tt>Application.database.UserRecord</tt> indicates that we want the <tt>UserRecord</tt> class file to be <tt>protected/database/UserRecord.php</tt>.

-</p>

-

-<p>

-We should see the following directory structure with two new files under <tt>protected/database</tt>:

-</p>

-

-<img src="<%~ directories2.gif %>" class="output" />

-

-<p>

-If we check the <tt>PostRecord</tt> class file, we should see the following content.

-</p>

-

-<com:TTextHighlighter CssClass="source" Language="php">

-class PostRecord extends TActiveRecord

-{

-    const TABLE='posts';

-    public $post_id;

-    public $author_id;

-    public $create_time;

-    public $title;

-    public $content;

-    public $status;

-

-    public static function finder($className=__CLASS__)

-    {

-        return parent::finder($className);

-    }

-}

-</com:TTextHighlighter>

-

-<p>

-As we see, for each field in the <tt>posts</tt> table, the class has a corresponding data member. The constant <tt>TABLE</tt> specifies the table name for the <tt>PostRecord</tt>. The static method <tt>finder()</tt> allows us to perform query and retrieve post data in terms of <tt>PostRecord</tt> objects.

-</p>

-

-<p>

-We can use the command line tool to do some testing with our newly created Active Record classes. Still in the interactive mode of the command line tool, we enter a PHP statement and should see the following. Interested readers may try some other PHP statements, such as <tt>UserRecord::finder()->findAll()</tt>.

-</p>

-

-<com:TTextHighlighter CssClass="source cli" Language="text">

->> PostRecord::finder()->findAll()

-array

-(

-    [0] => PostRecord#1

-    (

-        [post_id] => '1'

-        [author_id] => 'admin'

-        [create_time] => '1175708482'

-        [title] => 'first post'

-        [content] => 'this is my first post'

-        [status] => '0'

-        [TActiveRecord:_readOnly] => false

-        [TActiveRecord:_connection] => null

-        [TComponent:_e] => array()

-<h1>Relationship Between Posts and Users</h1>

-<p>

-Recall that there was a foreign key relationship between the <tt>users</tt> and <tt>posts</tt> table. The entity-relationship diagram is shown below for convienence.

-</p>

-

-<img src="<%~ ER.gif %>" class="output" />

-

-<p>

-From the entity-relationship diagram above, we see that the <tt>posts</tt> table contains a field named <tt>author_id</tt>. This <tt>author_id</tt> field is a foreign key to the reference table <tt>users</tt>. In particular, the values in the  <tt>author_id</tt> field should be of that from the <tt>users</tt> table's <tt>username</tt> field. One of the consequence of this relationship, thinking in terms of objects, is that each "post" belongs to an "author" and one "author" may have many "posts".

-</p>

-

-<p>

-We can model the relationship between <tt>posts</tt> and <tt>users</tt> table in Active Record by modifying the <tt>PostRecord</tt> and <tt>UserRecord</tt> classes as follows.

-</p>

-

-<com:TTextHighlighter CssClass="source" Language="php">

-class PostRecord extends TActiveRecord

-{

-    //... properties and methods as before

-

-    public $author; //holds an UserRecord

-

-    public static $RELATIONS=array

-    (

-        'author' => array(self::BELONGS_TO, 'UserRecord'),

-    );

-}

-</com:TTextHighlighter>

-

-<p>

-The static <tt>$RELATIONS</tt> property of <tt>PostRecord</tt> defines that the property <tt>$author</tt> belongs to an <tt>UserRecord</tt>. In <tt>array(self::BELONGS_TO, 'UserRecord')</tt>, the first element defines the relationship type, in this case <tt>self::BELONGS_TO</tt>. The second element is the name of related record, in this case an <tt>UserRecord</tt>. The <tt>UserRecord</tt> is defined similarly below, the difference is that, the user record has many <tt>PostRecord</tt>s.

-</p>

-

-<com:TTextHighlighter CssClass="source" Language="php">

-class UserRecord extends TActiveRecord

-{

-    //... properties and methods as before

-

-    public $posts=array(); //holds an array of PostRecord

-

-    public static $RELATIONS=array

-    (

-        'posts' => array(self::HAS_MANY, 'PostRecord'),

-    );

-}

-</com:TTextHighlighter>

-

-<p>

-An array of <tt>UserRecord</tt> with and its corresponding posts may be fetched as follows.

-</p>

-

-<com:TTextHighlighter CssClass="source" Language="php">

-$users = UserRecord::finder()->withPosts()->findAll();

-</com:TTextHighlighter>

-

-<com:TipBox>

-The method <tt>withXXX()</tt> (where XXX is the relationship property name, in this case, <tt>Posts</tt>) fetches the corresponding <tt>PostRecords</tt> using a second query (not by using a join). The <tt>withXXX()</tt> method accepts the same arguments as other finder methods of TActiveRecord, e.g. <tt>withPosts('status = ?', 0)</tt>.

+
+<p>
+Instead of writing the classes manually, we will use the <a href="?page=GettingStarted.Wsat">PRADO Web Site Administration Tool</a> to generate the classes for us.
+So we need to modify again our application configuration in the services section like follows:
+</p>
+
+ <p class="block-content">
+<com:TTextHighlighter CssClass="source" Language="xml">
+<services> 
+    ...

+</com:TTextHighlighter>
+</p>
+
+<p class="block-content">
+        Then you are ready to go to: http://localhost/yoursite/index.php?wsat=TWsatLogin where you should see
+        the following page:
+</p>
+<img src="<%~wsat_login.png%>" style="width: 700px;" />
+<p class="block-content">
+    In the text field you need to type the password previosly specified in the service inclusion. This 
+    is part of a basic security system to avoid undesirable persons to use this tool.
+</p>
+
+ <p class="block-content">
+        In order to generate AR classes you need to go to: http://localhost/divermania/index.php?wsat=TWsatGenerateAR 
+        by clicking the proper links in the welcome page. Then you should see the following page:        
+</p>
+<img src="<%~blog_wsat_generate_ar.png%>" style="width: 700px;" />
+
+<p>
+    In the <tt>Output Folder</tt> field we used the <a href="http://www.pradosoft.com/demos/quickstart/?page=Fundamentals.Components">namespace format</a> again, the path <tt>Application.database</tt> indicates that we want to put our class's files in the <tt>protected/database/</tt> folder.
+    The <tt>*</tt> in the <tt>Table Name</tt> field means that we want to generate all AR classes, you can specify a table name instead if you want to generate just a specific AR class.
+</p>
+
+<p>
+Afterward we should see the following directory structure with two new files under <tt>protected/database</tt>:
+</p>
+
+<img src="<%~ directories2.gif %>" class="output" />
+

+    );
+
