Download the PHP package akrabat/akrabat_db_schema_manager without Composer

Akrabat ZF library

See Akrabat_Db_Schema_Manager: Zend Framework database migrations for full details. This code is licensed under the New-BSD license.

Akrabat_Db_Schema_Manager is a tool for use with ZF1. If you need a standalone tool, then have a look at South for the Winter.

ZF1:

To get the Zend_Tool provider working:

1. Place a copy of ZF1 in /usr/local/include/zf1/, so that the Zend folder is in zf1/library/Zend

2. Update your ~/.bash_profile to set up an alias to the zf.sh script

   alias zf='export ZF_CONFIG_FILE=~/.zf.ini; /usr/local/include/zf1/bin/zf.sh'

   Restart your terminal or source ~/.bash_profile

3. If you haven't already done so, setup the storage directory and config file:

   zf --setup storage-directory
   zf --setup config-file

4. Place a copy of the Akrabat Tools in /usr/local/include/Akrabat:

   cd /usr/local/include
   git clone http://github.com/akrabat/Akrabat.git

5. Edit the created ~/.zf.ini. Change path so that it includes ZF1 and Akrabat/library, allow for auotoloading Akrabat and set up the provider:

   php.include_path = "/usr/local/include/zf1/library:/usr/local/include/Akrabat/library/"
   autoloadernamespaces.0 = "Akrabat_"
   basicloader.classes.0 = "Akrabat_Tool_DatabaseSchemaProvider"

6. zf should provide a help screen with the DatabaseSchema provider at the bottom.

Akrabat_Db_Schema_Manager

1. Create scripts/migrations folder in your ZF application

2. Create migration files within migrations with the file name format of nnn-Xxxx.php. e.g. 001-Users.php where:
   nnn => any number. The lower numbered files are executed first
   Xxx => any name. This is the class name within the file.

   In up(), database changes are applied, in down(), changes are reverted. If changes cannot be reverted, then down() should throw a Akrabat_Db_Schema_Exception.

3. Create a class in your migrations file. Example for 001-Users.php:

   class Users extends Akrabat_Db_Schema_AbstractChange 
   {
       function up()
       {
           $tableName = $this->_tablePrefix . 'users';
           $sql = "
               CREATE TABLE IF NOT EXISTS $tableName (
                 id int(11) NOT NULL AUTO_INCREMENT,
                 username varchar(50) NOT NULL,
                 password varchar(75) NOT NULL,
                 roles varchar(200) NOT NULL DEFAULT 'user',
                 PRIMARY KEY (id)
               ) ENGINE=InnoDB DEFAULT CHARSET=utf8;";
           $this->_db->query($sql);
   
           $data = array();
           $data['username'] = 'admin';
           $data['password'] = sha1('password');
           $data['roles'] = 'user,admin';
           $this->_db->insert($tableName, $data);
       }
   
       function down()
       {
           $tableName = $this->_tablePrefix . 'users';
           $sql= "DROP TABLE IF EXISTS $tableName";
           $this->_db->query($sql);
       }
   
   }

4. If you want a table prefix, add this to your application.ini:

   resources.db.table_prefix = "prefix"

Phing Task

1. Define the phing task in the build.xml

   <taskdef name="dbmigration" classname="phing.tasks.PhingAkrabatDbSchemaManager" />

2. Setup a phing target with the database options in the build.xml

   <target name="database-migration">
       <dbmigration adapter="mysqli" host="${db.host}" dbname="${db.name}" username="${db.user}" password="${db.pass}" />
   </target>

3. Run phing using the command line, by phing database-migration
