Extended Migration Command

This extension is an enhanced version of the Yii Database Migration Tool that adds module support and many more usefull features. If there is anything you would like to have added, or you found a bug please report it on github or contact me via email.

Features

  • Module-Support (migrations are distributed in a seperate folder for every module) so you can...
  • ...enable and disable Modules
  • ...add new module by migrating it up
  • ...remove a module by running its migrations down
  • ...select the modules you want to run migrations for in every run
  • ...declare Module-dependencies (coming soon)
  • ...different migration templates depending on modules (coming soon)

Resources

Requirements

  • Yii 1.1.6 or above (MigrateCommand was introduced in this version) if you copy MigrateCommand and CDbMigration you should be able to use this extension with any yii version.

Installation

  • Extract the release file under protected/extensions.
  • Add the following to your config file for yiic command:
'commandMap' => array(
        'migrate' => array(
            // alias of the path where you extracted the zip file
            'class' => 'application.extensions.yiiext.commands.migrate.EMigrateCommand',
            // this is the path where you want your core application migrations to be created
            'migrationPath' => 'application.db.migrations',
            // the name of the table created in your database to save versioning information
            'migrationTable' => 'tbl_migration',
	        // the application migrations are in a pseudo-module called "core" by default
            'applicationModuleName' => 'core',
	        // define all available modules
	        'modulePaths' => array(
		        'admin'      => 'application.modules.admin.db.migrations',
		        'user'       => 'application.modules.user.db.migrations',
		        'yourModule' => 'application.any.other.path.possible',
		        // ...
	        ),
	        // here you can configrue which modules should be active, you can disable a module by adding its name to this array
	        'disabledModules' => array(
	            'admin', 'anOtherModule', // ...
	        ),
	        // the name of the application component that should be used to connect to the database
            'connectionID'=>'db',
            // alias of the template file used to create new migrations
            'templateFile'=>'application.db.migration_template',
        ),
    ),

Please note: if you already used MigrateCommand before, make sure to add the module column to your migrationTable:

[sql]
 ALTER TABLE `tbl_migration` ADD COLUMN `module` varchar(32) DEFAULT NULL;
 UPDATE `tbl_migration` SET module='core';

Usage

General Usage

You can run yiic migrate help to see all parameters and a short example on how to use them.

The basics are explained in the Definitive Guide to Yii. Read them first if you haven't used database migration before. The usage of Extended Migration Command is not much different from the native one. The only command that is different is create where you have to additionally specify the modulename:

   yiic migrate create modulename create_user_table

This creates a new migration named 'create_user_table' in module 'modulename'. The native usage

   yiic migrate create create_user_table

creates a new migration named 'create_user_table' in the application(core).

--module Parameter

In all other commands (up, down, history, new, to and mark) you can use the parameter --module=<modulenames> where <modulenames> can be a comma seperated list of module names or a single module name. This parameter will limit the current command to affect only the specified modules. Some Examples:

   yiic migrate new --module=core

This will show you all new migrations for module core and

   yiic migrate up 5 --module=core,user

will migrate up the next 5 new migrations in modules core and user. If there are new migrations in other modules they will be ignored.

   yiic migrate history --module=core,user

will show you which migrations have been applied for modules core and user in the past. If you do not specify a module the command behaves like the native one but does the migration for all modules.

add a module

Simply enable it in your config and run yiic migrate up --module=yourModule.

remove a module

Run yiic migrate to m000000_000000 --module=yourModule. For this to work all your migrations must have the down()-method implemented correctly.
