codeigniter - 迁移和 CodeIgniter

Question

我有一个简单的问题。我想开始使用 CodeIgniter 迁移。但是我的配置文件夹中没有 migrations.php 文件，就像文档中所说的那样。另外，我是否需要在应用程序文件夹级别手动创建迁移文件夹？

Answer 1

奇怪的是，您的application/config/migration.php文件未包含在下载中，但是...即使配置文件不存在，迁移库仍将（或应该）在您的 CodeIgnitersystem/libraries文件夹中。

migration.php作为默认配置文件的一部分，有三个配置变量：

/*
|--------------------------------------------------------------------------
| Enable/Disable Migrations
|--------------------------------------------------------------------------
|
| Migrations are disabled by default but should be enabled 
| whenever you intend to do a schema migration.
|
*/
$config['migration_enabled'] = FALSE;


/*
|--------------------------------------------------------------------------
| Migrations version
|--------------------------------------------------------------------------
|
| This is used to set migration version that the file system should be on.
| If you run $this->migration->latest() this is the version that schema will
| be upgraded / downgraded to.
|
*/
$config['migration_version'] = 0;


/*
|--------------------------------------------------------------------------
| Migrations Path
|--------------------------------------------------------------------------
|
| Path to your migrations folder.
| Typically, it will be within your application path.
| Also, writing permission is required within the migrations path.
|

$config['migration_path'] = APPPATH . 'migrations/';
