Question

我是Yii Framwork的新手，我使用Multiple-database support in Yii中的步骤来连接不同的数据库，它对我帮助很大。

但是没有加载Css，当我打开index.php时，浏览器中会显示普通的HTML内容。

在更改模块中的GetDbConnection（）之后加载CSS需要进行哪些更改。

来自模特的Ad.php代码

<?php

class Ad extends MyActiveRecord
{
    public $password;
    public $repassword;

    public function getDbConnection()
    {
        return self::getCCDbConnection();
    }


    public static function model($className=__CLASS__)
    {
        return parent::model($className);
    }
    ....

}

先谢谢

这不能解决你的css问题，但是，这是在yii中使用多个dbs的正确方法。

这是在multiple db's中使用yii mvc的正确方法：

假设我有多个数据库，我用它来存储网址。

我不时需要更改数据库。

所以，我有使用gii生成的模型，最重要的是我有扩展和覆盖一些方法/函数的类。

UrlSlaveM扩展UrlSlave扩展CActiveRecord

默认情况下，UrlSlave我将连接到我的第一个数据库

我插入新数据时总是使用UrlSlaveM，以便我可以覆盖以下函数：

public function getDbConnection（）{ return Yii :: app（） - ＆gt; db1; }

这是一个完整的SlaveUrl模型：

<?php

/**
 * This is the model class for table "url".
 *
 * The followings are the available columns in table 'url':
 * @property string $id
 * @property integer $instance_id
 * @property integer $website_id
 * @property string $link
 * @property string $title
 * @property integer $created
 * @property integer $updated
 * @property integer $status
 */
class UrlSlave extends CActiveRecord {

    /**
     * Returns the static model of the specified AR class.
     * @param string $className active record class name.
     * @return UrlSlave the static model class
     */
    public static function model($className = __CLASS__) {
        return parent::model($className);
    }

    /**
     * @return CDbConnection database connection
     */
    public function getDbConnection() {
        return Yii::app()->db1;
    }

    /**
     * @return string the associated database table name
     */
    public function tableName() {
        return 'url';
    }

    /**
     * @return array validation rules for model attributes.
     */
    public function rules() {
        // NOTE: you should only define rules for those attributes that
        // will receive user inputs.
        return array(
            array('instance_id, website_id, link, title, created, updated, status', 'required'),
            array('instance_id, website_id, created, updated, status', 'numerical', 'integerOnly' => true),
            array('link, title', 'length', 'max' => 255),
            // The following rule is used by search().
            // Please remove those attributes that should not be searched.
            array('id, instance_id, website_id, link, title, created, updated, status', 'safe', 'on' => 'search'),
        );
    }

    /**
     * @return array relational rules.
     */
    public function relations() {
        // NOTE: you may need to adjust the relation name and the related
        // class name for the relations automatically generated below.
        return array(
        );
    }

    /**
     * @return array customized attribute labels (name=>label)
     */
    public function attributeLabels() {
        return array(
            'id' => 'ID',
            'instance_id' => 'Instance',
            'website_id' => 'Website',
            'link' => 'Link',
            'title' => 'Title',
            'created' => 'Created',
            'updated' => 'Updated',
            'status' => 'Status',
        );
    }

    /**
     * Retrieves a list of models based on the current search/filter conditions.
     * @return CActiveDataProvider the data provider that can return the models based on the search/filter conditions.
     */
    public function search() {
        // Warning: Please modify the following code to remove attributes that
        // should not be searched.

        $criteria = new CDbCriteria;

        $criteria->compare('id', $this->id, true);
        $criteria->compare('instance_id', $this->instance_id);
        $criteria->compare('website_id', $this->website_id);
        $criteria->compare('link', $this->link, true);
        $criteria->compare('title', $this->title, true);
        $criteria->compare('created', $this->created);
        $criteria->compare('updated', $this->updated);
        $criteria->compare('status', $this->status);

        return new CActiveDataProvider($this, array(
            'criteria' => $criteria,
        ));
    }

}

这是完整的UrlSlaveM模型：

<?php

class UrlSlaveM extends UrlSlave {

    const ACTIVE = 1;
    const INACTIVE = 0;
    const BANNED = -1;

    public static function model($className = __CLASS__) {
        return parent::model($className);
    }

    public function rules() {
        $parent_rules = parent::rules();
        $rules = array_merge(
                $parent_rules, array(
            array('link', 'unique'),
        ));
        return $rules;
    }

    public static $server_id = 1;
    public static $master_db;

    public function getDbConnection() {
        //echo __FUNCTION__;
        //die;
        //echo 111;
        self::$master_db = Yii::app()->{"db" . self::$server_id};
        if (self::$master_db instanceof CDbConnection) {
            self::$master_db->setActive(true);
            return self::$master_db;
        }
        else
            throw new CDbException(Yii::t('yii', 'Active Record requires a "db" CDbConnection application component.'));
    }

}

现在，通过将$server_id设置为1或2或3 ...您可以连接到另一个数据库

在添加数据之前，请将$server_id的值设置为UrlSlaveM::$server_id = 2;！

public static $server_id = 1;
    public static $master_db;

另外，在主配置文件中，设置如下：

'db' => array(
            'connectionString' => 'mysql:host=localhost;dbname=dvc',
            'emulatePrepare' => true,
            'username' => 'root',
            'password' => '',
            'charset' => 'utf8',
        ),
        'db2' => array(
            'connectionString' => 'mysql:host=localhost;dbname=dvc2',
            'username' => 'root',
            'password' => '',
            'charset' => 'utf8',
            'tablePrefix' => '',
            'class' => 'CDbConnection'          // DO NOT FORGET THIS!
        ),
        'db1' => array(
            'connectionString' => 'mysql:host=localhost;dbname=dvc1',
            'username' => 'root',
            'password' => '',
            'charset' => 'utf8',
            'tablePrefix' => '',
            'class' => 'CDbConnection'          // DO NOT FORGET THIS!
        ),

更改了Yii中的GetDbConnection（）后未加载Css
