本文实例讲述了YII Framework框架使用YIIC快速创建YII应用之migrate用法。分享给大家供大家参考,具体如下:
yii migrate

/* /www/yii_dev/yii/framework# php yiic migrate help Error: Unknown action: help USAGE yiic migrate [action] [parameter] DESCRIPTION This command provides support for database migrations. The optional \'action\' parameter specifies which specific migration task to perform. It can take these values: up, down, to, create, history, new, mark. If the \'action\' parameter is not given, it defaults to \'up\'. Each action takes different parameters. Their usage can be found in the following examples. EXAMPLES * yiic migrate Applies ALL new migrations. This is equivalent to \'yiic migrate to\'. * yiic migrate create create_user_table Creates a new migration named \'create_user_table\'. * yiic migrate up 3 Applies the next 3 new migrations. * yiic migrate down Reverts the last applied migration. * yiic migrate down 3 Reverts the last 3 applied migrations. * yiic migrate to 101129_185401 Migrates up or down to version 101129_185401. * yiic migrate mark 101129_185401 Modifies the migration history up or down to version 101129_185401. No actual migration will be performed. * yiic migrate history Shows all previously applied migration information. * yiic migrate history 10 Shows the last 10 applied migrations. * yiic migrate new Shows all new migrations. * yiic migrate new 10 Shows the next 10 migrations that have not been applied. */
在我们开发程序的过程中,数据库的结构也是不断调整的。我们的开发中要保证代码和数据库库的同步。因为我们的应用离不开数据库。例如: 在开发过程中,我们经常需要增加一个新的表,或者我们后期投入运营的产品,可能需要为某一列添加索引。我们必须保持数据结构和代码的一致性。如果代码和数据库不同步,可能整个系统将无法正常运行。出于这个原因。yii提供了一个数据库迁移工具,可以保持代码和数据库是同步。方便数据库的回滚和更新。
功能正如描述。主要提供了数据库迁移功能。
命令格式
yiic migrate [action] [parameter]
action参数用来制定执行哪一个迁移任务。可以一使用
up, down, to, create, history, new, mark.这些命令
如果没有action参数,默认为up
parameter根据action的不同而有所变化。
上述例子中给出了说明。
官方也给出了详细的例子。
http://www.yiiframework.com/doc/guide/1.1/zh_cn/database.migration#creating-migrations
这里不再详细累述。用到的时候参考使用就可以了。
补充:yii2.0使用migrate创建后台登陆
重新创建一张数据表来完成后台登陆验证
为了大家看得明白,直接贴代码
一、使用Migration创建表admin
console\\migrations\\m130524_201442_init.php
use yii\\db\\Schema; use yii\\db\\Migration; class m130524_201442_init extends Migration { const TBL_NAME = \'{{%admin}}\'; public function safeUp() { $tableOptions = null; if ($this->db->driverName === \'mysql\') { // http://stackoverflow.com/questions/766809/whats-the-difference-between-utf8-general-ci-and-utf8-unicode-ci $tableOptions = \'CHARACTER SET utf8 COLLATE utf8_unicode_ci ENGINE=InnoDB\'; } $this->createTable(self::TBL_NAME, [ \'id\' => Schema::TYPE_PK, \'username\' => Schema::TYPE_STRING . \' NOT NULL\', \'auth_key\' => Schema::TYPE_STRING . \'(32) NOT NULL\', \'password_hash\' => Schema::TYPE_STRING . \' NOT NULL\', //密码 \'password_reset_token\' => Schema::TYPE_STRING, \'email\' => Schema::TYPE_STRING . \' NOT NULL\', \'role\' => Schema::TYPE_SMALLINT . \' NOT NULL DEFAULT 10\', \'status\' => Schema::TYPE_SMALLINT . \' NOT NULL DEFAULT 10\', \'created_at\' => Schema::TYPE_INTEGER . \' NOT NULL\', \'updated_at\' => Schema::TYPE_INTEGER . \' NOT NULL\', ], $tableOptions); $this->createIndex(\'username\', self::TBL_NAME, [\'username\'],true); $this->createIndex(\'email\', self::TBL_NAME, [\'email\'],true); } public function safeDown() { $this->dropTable(self::TBL_NAME); } }
使用命令行来创建admin数据库
1、win7下使用命令:
在项目根目下,右键选择User composer here(前提是安装了全局的composer),
yii migrate
即创建数据表 admin成功
2、linux下命令一样(此处略)
二、使用gii创建模型
此处略,很简单的步聚。
注:把admin模型创在 backend/models下面 (放哪里看个人喜好)
代码如下
namespace backend\\models; use Yii; use yii\\base\\NotSupportedException; use yii\\behaviors\\TimestampBehavior; use yii\\db\\ActiveRecord; use yii\\web\\IdentityInterface; /** * This is the model class for table \"{{%admin}}\". * * @property integer $id * @property string $username * @property string $auth_key * @property string $password_hash * @property string $password_reset_token * @property string $email * @property integer $role * @property integer $status * @property integer $created_at * @property integer $updated_at */ class AgAdmin extends ActiveRecord implements IdentityInterface { const STATUS_DELETED = 0; const STATUS_ACTIVE = 10; const ROLE_USER = 10; const AUTH_KEY = \'123456\'; /** * @inheritdoc */ public static function tableName() { return \'{{%admin}}\'; } /** * @inheritdoc */ public function behaviors() { return [ TimestampBehavior::className(), ]; } /** * @inheritdoc */ public function rules() { return [ [[\'username\', \'email\',], \'required\'], [[\'username\', \'email\'], \'string\', \'max\' => 255], [[\'username\'], \'unique\'], [[\'username\'], \'match\', \'pattern\'=>\'/^[a-z]\\w*$/i\'], [[\'email\'], \'unique\'], [[\'email\'], \'email\'], [\'status\', \'default\', \'value\' => self::STATUS_ACTIVE], [\'status\', \'in\', \'range\' => [self::STATUS_ACTIVE, self::STATUS_DELETED]], [\'role\', \'default\', \'value\' => self::ROLE_USER], [\'auth_key\', \'default\', \'value\' => self::AUTH_KEY], [\'role\', \'in\', \'range\' => [self::ROLE_USER]], ]; } /** * @inheritdoc */ public static function findIdentity($id) { return static::findOne([\'id\' => $id, \'status\' => self::STATUS_ACTIVE]); } /** * @inheritdoc */ public static function findIdentityByAccessToken($token, $type = null) { return static::findOne([\'access_token\' => $token]); //throw new NotSupportedException(\'\"findIdentityByAccessToken\" is not implemented.\'); } /** * Finds user by username * * @param string $username * @return static|null */ public static function findByUsername($username) { return static::findOne([\'username\' => $username, \'status\' => self::STATUS_ACTIVE]); } /** * Finds user by password reset token * * @param string $token password reset token * @return static|null */ public static function findByPasswordResetToken($token) { if (!static::isPasswordResetTokenValid($token)) { return null; } return static::findOne([ \'password_reset_token\' => $token, \'status\' => self::STATUS_ACTIVE, ]); } /** * Finds out if password reset token is valid * * @param string $token password reset token * @return boolean */ public static function isPasswordResetTokenValid($token) { if (empty($token)) { return false; } $expire = Yii::$app->params[\'user.passwordResetTokenExpire\']; $parts = explode(\'_\', $token); $timestamp = (int) end($parts); return $timestamp + $expire >= time(); } /** * @inheritdoc */ public function getId() { return $this->getPrimaryKey(); } /** * @inheritdoc */ public function getAuthKey() { return $this->auth_key; } /** * @inheritdoc */ public function validateAuthKey($authKey) { return $this->getAuthKey() === $authKey; } /** * Validates password * * @param string $password password to validate * @return boolean if password provided is valid for current user */ public function validatePassword($password) { return Yii::$app->security->validatePassword($password, $this->password_hash); } /** * Generates password hash from password and sets it to the model * * @param string $password */ public function setPassword($password) { $this->password_hash = Yii::$app->security->generatePasswordHash($password); } /** * Generates \"remember me\" authentication key */ public function generateAuthKey() { $this->auth_key = Yii::$app->security->generateRandomString(); } /** * Generates new password reset token */ public function generatePasswordResetToken() { $this->password_reset_token = Yii::$app->security->generateRandomString() . \'_\' . time(); } /** * Removes password reset token */ public function removePasswordResetToken() { $this->password_reset_token = null; } }
三、使用migrate 为后如初使化一个登陆帐号
1、console\\controllers创建InitController.php
/** * * @author chan <maclechan@qq.com> */ namespace console\\controllers; use backend\\models\\Admin ; class InitController extends \\yii\\console\\Controller { /** * Create init user */ public function actionAdmin() { echo \"创建一个新用户 ...\\n\"; // 提示当前操作 $username = $this->prompt(\'User Name:\'); // 接收用户名 $email = $this->prompt(\'Email:\'); // 接收Email $password = $this->prompt(\'Password:\'); // 接收密码 $model = new AgAdmin(); // 创建一个新用户 $model->username = $username; // 完成赋值 $model->email = $email; $model->password = $password; if (!$model->save()) // 保存新的用户 { foreach ($model->getErrors() as $error) // 如果保存失败,说明有错误,那就输出错误信息。 { foreach ($error as $e) { echo \"$e\\n\"; } } return 1; // 命令行返回1表示有异常 } return 0; // 返回0表示一切OK } }
2、使用命令:
在项目根目下,右键选择User composer here(前提是安装了全局的composer),
yii init/admin
到此,打开数据表看下,己经有了数据。
四、后台登陆验证
1、backend\\controllers\\SiteController.php 里actionLogin方法不用变
2、把common\\models\\LoginForm.php复制到backend\\models只要把LoginForm.php里面的方法getUser()修改一个单词即可,如下
public function getUser() { if ($this->_user === false) { $this->_user = Admin::findByUsername($this->username); } return $this->_user; }
3、backend\\config\\main.php 只要修改
\'user\' => [ \'identityClass\' => \'backend\\models\\Admin\', \'enableAutoLogin\' => true, ],
此外,在作修改时,请注意下命令空不要搞乱了。
到此,结束。
