/*/www/yii_dev/yii/framework# php yiic migrate helpError: Unknown action: helpUSAGE 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 migrateApplies ALL new migrations. This is equivalent to "yiic migrate to".* yiic migrate create create_user_tableCreates a new migration named "create_user_table".* yiic migrate up 3Applies the next 3 new migrations.* yiic migrate downReverts the last applied migration.* yiic migrate down 3Reverts the last 3 applied migrations.* yiic migrate to 101129_185401Migrates up or down to version 101129_185401.* yiic migrate mark 101129_185401Modifies the migration history up or down to version 101129_185401.No actual migration will be performed.* yiic migrate historyShows all previously applied migration information.* yiic migrate history 10Shows the last 10 applied migrations.* yiic migrate newShows all new migrations.* yiic migrate new 10Shows 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
consolemigrationsm130524_201442_init.php
use yiidbSchema;use yiidbMigration;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 backendmodels;use Yii;use yiiaseNotSupportedException;use yiiehaviorsTimestampBehavior;use yiidbActiveRecord;use yiiwebIdentityInterface;/** * 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、consolecontrollers创建InitController.php
/** * * @author chan <maclechan@qq.com> */namespace consolecontrollers;use backendmodelsAdmin ;class InitController extends yiiconsoleController{/** * Create init user */public function actionAdmin(){echo "创建一个新用户 ...
"; // 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
";}}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、backendcontrollersSiteController.php 里actionLogin方法不用变
2、把commonmodelsLoginForm.php复制到backendmodels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、backendconfigmain.php 只要修改
"user" => ["identityClass" => "backendmodelsAdmin","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。
