PHP YII Framework框架使用YIIC快速創建YII應用之migrate用法實例詳解
本文實例講述了YII Framework框架使用YIIC快速創建YII應用之migrate用法。分享給大家供大家參考，具體如下：yii migrate查看幫助/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 html' target='_blank'>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.在我們開發程序的過程中，數據庫的結構也是不斷調整的。我們的開發中要保證代碼和數據庫庫的同步。因為我們的應用離不開數據庫。例如: 在開發過程中，我們經常需要增加一個新的表，或者我們后期投入運營的產品，可能需要為某一列添加索引。我們必須保持數據結構和代碼的一致性。如果代碼和數據庫不同步，可能整個系統將無法正常運行。出于這個原因。yii提供了一個數據庫遷移工具，可以保持代碼和數據庫是同步。方便數據庫的回滾和更新。功能正如描述。主要提供了數據庫遷移功能。命令格式yiic migrate [action] [parameter]action參數用來制定執行哪一個遷移任務?？梢砸皇褂胾p, down, to, create, history, new, mark.這些命令如果沒有action參數，默認為upparameter根據action的不同而有所變化。上述例子中給出了說明。官方也給出了詳細的例子。http://www.yiiframework.com/doc/guide/1.1/zh_cn/database.migration#creating-migrations這里不再詳細累述。用到的時候參考使用就可以了。補充：yii2.0使用migrate創建后臺登陸重新創建一張數據表來完成后臺登陸驗證為了大家看得明白，直接貼代碼一、使用Migration創建表adminconsole/migrations/m130524_201442_init.phpuse 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', //密碼 '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);使用命令行來創建admin數據庫1、win7下使用命令：在項目根目下，右鍵選擇User composer here(前提是安裝了全局的composer)，
yii migrate即創建數據表 admin成功2、linux下命令一樣（此處略）二、使用gii創建模型此處略，很簡單的步聚。注：把admin模型創在 backend/models下面（放哪里看個人喜好）
代碼如下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 $updated_atclass AgAdmin extends ActiveRecord implements IdentityInterface const STATUS_DELETED = 0; const STATUS_ACTIVE = 10; const ROLE_USER = 10; const AUTH_KEY = '123456'; * @inheritdoc public static function tableName() return '{{%admin}}'; * @inheritdoc public function behaviors() return [ TimestampBehavior::className(), * @inheritdoc public function rules() return [ [['username', 'email',], 'required'], [['username', 'email'], 'string', 'max' = 255], [['username'], 'unique'], [['username'], 'match', 'pattern'= '/^[a-z]/w*$/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 為后如初使化一個登陸帳號1、console/controllers創建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 "創建一個新用戶 .../n"; // 提示當前操作 $username = $this- prompt('User Name:'); // 接收用戶名 $email = $this- prompt('Email:'); // 接收Email $password = $this- prompt('Password:'); // 接收密碼 $model = new AgAdmin(); // 創建一個新用戶 $model- username = $username; // 完成賦值 $model- email = $email; $model- password = $password; if (!$model- save()) // 保存新的用戶 foreach ($model- getErrors() as $error) // 如果保存失敗，說明有錯誤，那就輸出錯誤信息。 foreach ($error as $e) echo "$e/n"; return 1; // 命令行返回1表示有異常 return 0; // 返回0表示一切OK2、使用命令：在項目根目下，右鍵選擇User composer here(前提是安裝了全局的composer)，
yii init/admin到此，打開數據表看下，己經有了數據。四、后臺登陸驗證1、backend/controllers/SiteController.php 里actionLogin方法不用變2、把common/models/LoginForm.php復制到backend/models只要把LoginForm.php里面的方法getUser()修改一個單詞即可，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，在作修改時，請注意下命令空不要搞亂了。到此，結束。更多關于Yii相關內容感興趣的讀者可查看本站專題：《Yii框架入門及常用技巧總結》、《php優秀開發框架總結》、《smarty模板入門基礎教程》、《php日期與時間用法總結》、《php面向對象程序設計入門教程》、《php字符串(string)用法總結》、《php+mysql數據庫操作入門教程》及《php常見數據庫操作技巧匯總》希望本文所述對大家基于Yii框架的PHP程序設計有所幫助。PHP教程
