Update from 1.0 to 1.1
======================

This document details the changes made to Doctrine 1.1 to make it easier for you
to upgrade your projects to use this version.

Doctrine Record
---------------

isValid() & isModified() Optional Deep Parameter
------------------------------------------------

When you use the `Doctrine_Record::isValid()` and `Doctrine_Record::isModified()`
methods you can optionally pass a `$deep` argument with a value of true so that
Doctrine will check any references that exist. So if a reference record is
invalid or modified then the parent object will return as such.

Here is an example using `isModified()`:

    [php]
    $user = new TUser();
    $mail = new Email();
    $mail->address = 'test';
    $user->emails[] = $mail;

    // Returns true because the referenced email model is modified
    $modified = $user->isModified(true);

Here is an example using `isValid()`:

    [php]
    $user = new User();
    $mail = new Email();

    $user->name = 'floriank';
    $user->emails[] = $mail;

    // Returns false because the referenced Email object does not have an address set
    $valid = $user->isValid(true);

[r5098](http://trac.doctrine-project.org/changeset/5098) - Added ability to 
define custom accessors/mutators for a Doctrine record

    [php]
    public function setTableDefinition()
    {
        $this->hasColumn('username', 'string');
    }

    public function setUp()
    {
        $this->hasAccessor('username', 'customUsernameAccessor');
        $this->hasMutator('username', 'customUsernameMutator');
    }

    public function customUsernameAccessor()
    {
        return $this->_get('username');
    }

    public function customUsernameMutator($value)
    {
        $this->_set('username', $value);
    }

[r5236](http://trac.doctrine-project.org/changeset/5236) - Added ability to 
alias record listeners

    [php]
    $this->addListener(new My_Listener_FooListener($this->_options), 'FooListener');

No aliasing and no options usage:

    [yml]
    Foo:
      columns:
        bar: string(50)
      listeners: [My_Listener_FooListener]

No aliasing and using options

    [yml]
    Foo:
      columns:
        bar: string(50)
      listeners:
        My_Listener_FooListener:
          useOptions: true

Using alias definition

    [yml]
    Foo:
      columns:
        bar: string(50)
      listeners:
        FooListener:
          class: My_Listener_FooListener
          useOptions: true 

[r5236](http://trac.doctrine-project.org/changeset/5236) - Added ability to 
enable/disable record listeners

Possibility to remove all listeners of all record listeners

    [php]
    Doctrine::getTable('Foo')->getRecordListener()->setOption('disabled', true);

Possibility to remove some listeners of all record listeners

    [php]
    Doctrine::getTable('Foo')->getRecordListener()->setOption('disabled', 
      array('preSerialize', 'postHydrate'));

Possibility to remove all listeners of a single record listener

    [php]
    Doctrine::getTable('Foo')->getRecordListener()->get('FooListener')
      ->setOption('disabled', true);

Possibility to remove some listeners of a single record listener

    [php]
    Doctrine::getTable('Foo')->getRecordListener()->get('FooListener')
      ->setOption('disabled', array('preSave', 'postInsert'));

[r5241](http://trac.doctrine-project.org/changeset/5240) - Added ability to 
work with mapped values as if they were part of the record. It is useful to 
store transient data into record (this data is not persisted to database).

    [php]
    class Foo extends Doctrine_Record {
        public function setTableDefinition() {
            $this->mapValue('name');
        }

        // ...
    }

    $foo = new Foo();

    $foo->name = 'guilhermeblanco';
    echo $foo->name; // prints: guilhermeblanco

[r5014](http://trac.doctrine-project.org/changeset/5014) - Added support for 
`FROM User u WHERE u.id IN ?` in the Doctrine_Query api.

    [php]
    $q = Doctrine_Query::create()
      ->from('User u')
      ->where('u.id IN ?', array(1, 2, 3));
    $users = $q->execute();

[r5019](http://trac.doctrine-project.org/changeset/5019) - `unlink()` and 
`link()` have been changed to not delete references until `save()` is called 
on the object. Also, fixed synchronizeWithArray() to synchronize many to many 
relationships.

    [php]
    // Does not link until save()
    $user = Doctrine::getTable('User')->find(1);
    $user->link('Groups', array(1, 2, 3));
    $user->save();

    // Third argument will force it to save instantly
    $user = Doctrine::getTable('User')->find(1);
    $user->link('Groups', array(1, 2, 3), true);

    $user = Doctrine::getTable('User')->find(1);
    $userArray = array('Group' => array(1, 2, 3));

    $user->synchronizeWithArray($userArray);
    $user->save();

You can also use the same structure with the `fromArray()` function:

    [php]
    $user->fromArray($userArray);
    $user->save();

[r5034](http://trac.doctrine-project.org/changeset/5034) - You can now retrieve 
the old values of records through the getModified() function. By default it 
returns an array of fieldName => newValue but if you specify getModified(true) 
it will return the old values.

    [php]
    $users = Doctrine::getTable('User')->findAll();
    $user = $users->getFirst();
    $user->name = 'zYne-';
    
    $oldValues = $user->getModified(true);
    /*
    array(
      'name' => 'zYne',
    )
    */
    
    $newValues = $user->getModified(false);
    /*
    array(
      'name' => 'zYne-',
    )
    */

[r5035](http://trac.doctrine-project.org/changeset/5035) - Added ability to use 
custom setters with fromArray()

    [php]
    public function setTableDefinition()
    {
        $this->hasColumn('password');
    }

    public function setEncryptedPassword($password)
    {
        return $this->_set('password', md5($password));
    }

    $user->fromArray(array('encrypted_password' => 'changeme'));

Will invoke the custom setter setEncryptedPassword()

Default Options
---------------

[r5027](http://trac.doctrine-project.org/changeset/5039) - Added support for 
setting default charset and collate for tables.

Set globally on a Doctrine_Manager instance.

    [php]
    $manager->setCollate('utf8_unicode_ci');
    $manager->setCharset('utf8');

The same can be set on the Doctrine_Connection and Doctrine_Record levels.

    [php]
    $connection->setCollate('utf8_unicode_ci');
    $connection->setCharset('utf8');

    public function setTableDefinition()
    {
      $this->setCollate('utf8_unicode_ci');
      $this->setCharset('utf8');
    }

[r5030](http://trac.doctrine-project.org/changeset/5039) - Added support for 
setting default options for columns and auto added identifier columns.

The following is now possible on Doctrine_Manager, Doctrine_Connection and 
Doctrine_Record.

    [php]
    $manager->setAttribute(Doctrine::ATTR_DEFAULT_COLUMN_OPTIONS, 
      array('type' => 'string', 'length' => 255, 'notnull' => true));

You can also customize the values that make up the auto added identifier column as well.

    [php]
    // %s in the name is replaced with the table name.
    $manager->setAttribute(Doctrine::ATTR_DEFAULT_IDENTIFIER_OPTIONS, 
      array('name' => '%s_id', 'type' => 'string', 'length' => 16));

[r5079](http://trac.doctrine-project.org/changeset/5079) - Added ability to 
retrieve the modified properties from the last transaction with the 
Doctrine_Record::getLastModified() method

    [php]
    $user = new User();
    $user->username = 'jwage';
    print_r($user->getModified()); // array('username' => 'jwage')
    $user->save();

    // getModified() returns the current modified properties and in this case 
    // now no propeties are modified.
    print_r($user->getModified()); // array()

    // you can retrieve the last modified properties like the following
    print_r($user->getLastModified()); // array('username' => 'jwage')

Doctrine Query
--------------

[r5031](http://trac.doctrine-project.org/changeset/5031) - A query can now be 
transformed from an update() or delete() to a select() or any combination. Run a 
query once to update a field then turn it to a select and execute it.

    [php]
    $q = Doctrine_Query::create()
        ->update('User u')
        ->set('u.password', '?', 'newpassword')
        ->where('u.username = ?', 'jwage');
    $q->execute();

    // Change it to a select query
    $q->select();
    $user = $q->fetchOne();

[r5018](http://trac.doctrine-project.org/changeset/5018) - Added 
`Doctrine::ATTR_AUTO_FREE_QUERY_OBJECTS` for auto freeing query objects after 
execution 

    [php]
    $manager->setAttribute('auto_free_query_objects');
    $q = Doctrine_Query::create()
      ->from('User u')
    $users = $q->execute(); // $q->free() is triggered

[r5121](http://trac.doctrine-project.org/changeset/5121) - Added new 
Doctrine_Query_Abstract::getFlattenedParams() to replace 
Doctrine_Query_Abstract::getParams() and Doctrine_Query_Abstract::getParams() 
now returns the raw unmodified array of query parameters.

Doctrine Collection
-------------------

[r5032](http://trac.doctrine-project.org/changeset/5032) - You can now convert 
a Doctrine_Collection in to a key value array made up of the values from the two 
specified columns.

    [php]
    $q = Doctrine_Query::create()
        ->from('User u');
    $users = $q->execute();

    $array = $users->toKeyValueArray('id', 'name');
    print_r($array);

    /*
    array(
      4 => 'zYne',
      5 => 'Arnold Schwarzenegger',
      6 => 'Michael Caine',
      7 => 'Takeshi Kitano',
      8 => 'Sylvester Stallone',
      9 => 'Kurt Russell',
      10 => 'Jean Reno',
      11 => 'Edward Furlong',
    )
    */

Doctrine Validation
-------------------

[r5033](http://trac.doctrine-project.org/changeset/5033) - You can now specify a 
unique validator on a set of fields. The argument of the unique() function can 
either be an array of fields or an argument for each field.

    [php]
    public function setTableDefinition()
    {
        $this->hasColumn('username', 'string', 255);
        $this->hasColumn('email_address', 'string', 255);

        $this->unique('username', 'email_address');
    }

Registering Validators
----------------------

In Doctrine 1.1 you now have the ability to register custom validators so that 
Doctrine is aware of them. You can also get the allowed validators.

    [php]
    // Register a new validator
    $manager = Doctrine_Manager::getInstance();
    $manager->registerValidators('MyValidator');

    // Get array of validators
    $validators = $manager->getValidators();

E-Mail Validator
----------------

You now have the ability to configure the Email validator to not check the mx 
record of the e-mail address.

    [php]
    class User extends Doctrine_Record
    {
        public function setTableDefinition()
        {
            $this->hasColumn('username', 'string', 255);
            $this->hasColumn('password', 'string', 255);
            $this->hasColumn('email_address', 'string', 255, array('email' => array('check_mx' => false)));
        }
    }

Doctrine Hydration
------------------

[r5016](http://trac.doctrine-project.org/changeset/5016) - A performance change 
was made to the hydration process which should yield some improvements when 
hydrating large result sets.

Doctrine Schema Files
---------------------

You are now able to pass extra attributes through the YAML schema parser to 
store any custom column information and you have access to it through the 
Doctrine_Table.

    [yml]
    User:
      columns:
        username:
          type: string(255)
          extra:
            test: 123
        password:
          type: string(255)

You can now access the data with the following php code:

    [php]
    $username = Doctrine::getTable('User')->getDefinitionOf('username');
    echo $username['extra']['test']; // 123

Generated Models
----------------

Doctrine will now generate phpDoc property tags with the generated base classes.

    [yml]
    User:
      columns:
        username: string(255)
        password: string(255)

    Phonenumber:
      columns:
        user_id: integer
        phonenumber: string
      relations:
        User:
          foreignAlias: Phonenumbers

Generates the following User and Phonenumber class

    [php]
    /**
     * BaseUser
     * 
     * This class has been auto-generated by the Doctrine ORM Framework
     * 
     * @property string $username
     * @property string $password
     * @property Doctrine_Collection $Phonenumbers
     * 
     * @package    ##PACKAGE##
     * @subpackage ##SUBPACKAGE##
     * @author     ##NAME## <##EMAIL##>
     * @version    SVN: $Id: Builder.php 5270 2008-12-05 20:47:43Z jwage $
     */
    abstract class BaseUser extends Doctrine_Record
    {
      public function setTableDefinition()
      {
        $this->setTableName('user');
        $this->hasColumn('username', 'string', 255, array('type' => 'string', 'length' => '255'));
        $this->hasColumn('password', 'string', 255, array('type' => 'string', 'length' => '255'));
      }

      public function setUp()
      {
        $this->hasMany('Phonenumber as Phonenumbers', array('local' => 'id',
                                                            'foreign' => 'user_id'));
      }
    }

    /**
     * BasePhonenumber
     * 
     * This class has been auto-generated by the Doctrine ORM Framework
     * 
     * @property integer $user_id
     * @property string $phonenumber
     * @property User $User
     * 
     * @package    ##PACKAGE##
     * @subpackage ##SUBPACKAGE##
     * @author     ##NAME## <##EMAIL##>
     * @version    SVN: $Id: Builder.php 5270 2008-12-05 20:47:43Z jwage $
     */
    abstract class BasePhonenumber extends Doctrine_Record
    {
      public function setTableDefinition()
      {
        $this->setTableName('phonenumber');
        $this->hasColumn('user_id', 'integer', null, array('type' => 'integer'));
        $this->hasColumn('phonenumber', 'string', null, array('type' => 'string'));
      }

      public function setUp()
      {
        $this->hasOne('User', array('local' => 'user_id',
                                    'foreign' => 'id'));
      }
    }

Versionable Behavior
--------------------

[r5097](http://trac.doctrine-project.org/changeset/5097) - Added ability to 
disable automatic deleting of versions when a record is deleted

    [php]
    $this->actAs('Versionable', array('deleteVersions' => false));

And the yaml version:

    [yml]
    actAs:
      Versionable:
        deleteVersions: false

Migrations
----------

In Doctrine 1.1 we have made a few changes to migrations.

* Generated migration classes are prefixed with a timestamp instead of a 
incremented integer.
* Added possibility for automation of up/down methods.
* Re-ordered arguments for addColumn() so that type is first before length.
* Added `Doctrine_Migration_Diff` tool.
* Migration classes should now extend a class named `Doctrine_Migration_Base` instead of `Doctrine_Migration`.

Here is an example of how you can automate the opposite up or down of a migration
api method.

    [php]
    public function migrate($direction)
    {
      $this->column($direction, 'table_name', 'column_name', 'string', '255');
    }

The above example will create the column when $direction == up and will remove 
the column when $direction == down.

* Introduced new CLI task generate-migrations-diff for producing differences between your generated PHP models and your YAML schema files.

SoftDelete
----------

In Doctrine 1.1 the SoftDelete behavior was changed slightly to store a `deleted_at`
timestamp to indicate a deleted record rather than a `deleted` boolean flag.

We still kept the BC, so you're `deleted` boolean column will still be supported as 
long as you have defined in your schema:

Foo:
  actAs:
    SoftDelete:
      name: deleted
      type: boolean
  columns:
    bar: string

By doing that, you'll not need to update your existent database schema. Otherwise,
you will need to modify your existing database schema and rename the `deleted`
column to `deleted_at` and modify the type to be a timestamp.

Timestamps
----------

PostgreSQL now uses TIMESTAMPS with timezone by default for timestamps.
TIME defaults to TIME without timezone and TIMESTAMP to TIMESTAMP with timezone.
Time validation is now accepting time zones and milliseconds accordingly to the
ISO 8601.

Searchable
----------

You now have the ability to pass an array of options for the search analyzers. For example the Utf8 analyzer can accept an encoding option:

    [php]
    BlogPost:
      actAs:
        Searchable:
          analyzer: Doctrine_Search_Analyzer_Utf8
          analyzer_options:
            encoding: utf-8
      columns:
        title: string(255)
        body: clob
