Yii 1.1: Using SQLite and CDbMessageSource as a module

8 followers

There are scenarios when you work with DVCS (like Mercurial or Git) and CDbMessageSource. To my experience keeping the development database and production database in sync can be very time consuming. Plus, when working in a team, you never know when the database was updated.

In this wiki, I show you an alternative approach to this problem. By putting the CDbMessageSource in a separate module, firstly we can have a cleaner logic. By using a sqlite file only for the translation database, secondly version control systems can track changes to this (binaray) file. And thirdly, another advantage comes in by simply copying the file from the live server back to the development server. (I always had a hard time logging on to the live system, only to export the two CDbMessageSource tables and then to import them back to the local db.)

Before continuing please ensure:

  • You have created a yii webapp
  • You can work with GiiModule
  • Your webserver supports SQLite
  • You have a SQLite Manager (such as the Firefox-Plugin SQLite Manager ready working

Mercurial download

Since this is no real extension and nevertheless I provide a lot of code, feel free to go to my public repository and hg clone https://bitbucket.org/pheadeaux/yii-i18n-sqlite-module-demo (Bitbucket site).

Create a new i18n module using Gii

With GiiModule create a new module under protected\modules\i18n which generates:

modules\i18n\I18nModule.php
modules\i18n\components
modules\i18n\controllers\DefaultController.php
modules\i18n\messages
modules\i18n\models
modules\i18n\views\default\index.php
modules\i18n\views\layouts

Delete the folder modules\i18n\messages. Create a new folder modules\i18n\data.

With the following edit modules\i18n\I18nModule.php to have a lookup for the category names to be used.

<?php
class I18nModule extends CWebModule {
// leave the rest untouched …
    /**
     * @return array of allowed category Names
     */
    public static function CategoryList() {
        // modify to match app requirements
        return array(
            'App' => 'App',
            'Error' => 'Error',
            'Hint' => 'Hint',
            'EMail' => 'EMail',
            'Pdf' => 'Pdf'
        );
    }
}

Edit the protected\config\main.php

To actually use a SQLite database separate from the normal db-connection, update the protected\config\main.php. Register the new created module, set up a SQLite connection and tell the CDbMessageSource to use the SQLite-file.

<?php
return array(
    //  ......
    // user language (for Locale)
    'language' => 'de',
    //language for messages and views
    'sourceLanguage' => 'en_us',
    // charset to use
    'charset' => 'utf-8',
    // application modules
    'modules' => array(
        'i18n',
    ),
    //  ......
    // application components
    'components' => array(
        // used for i18n-module
        // uncommented line: extension=php_pdo_sqlite.dll in file php.ini and resart apache to make sure correct driver is loaded
        // for TurnkeyLAMP intall do: apt-get install php5-sqlite
        // make shure to set sqlite-FOLDER to access 755 !
        'i18n_db' => array(
            'class' => 'CDbConnection',
            'connectionString' => 'sqlite:' . dirname(__FILE__) . '/../modules/i18n/data/i18n.sqlite',
        ),
        'i18n' => array(
            'class' => 'CDbMessageSource',
            'connectionID' => 'i18n_db',
            'sourceMessageTable' => 'yii_i18n_source_messages', // will not use Yii Core framework/i18n/CdbMessageSource.php public case sensitive attributes values.
            'translatedMessageTable' => 'yii_i18n_messages', // will not use Yii Core framework/i18n/CdbMessageSource.php public case sensitive attributes values.
        ),
    ),
    // application-level parameters that can be accessed
    // using Yii::app()->params['paramName']
    'params' => array(
        // ......
        'supportedLanguages' => array('de' => 'Deutsch', 'en' => 'English'),
    ),
);

Create the i18n.sqlite-file

Use your favorite SQLite Manager to create a SQLite file under modules\i18n\data\i18n.sqlite. The filename of course is completely arbitrary. But be sure to update the samples given here, if you change this name. Init the db with the following which is adapted from the CDbMessageSource API:

CREATE TABLE "yii_i18n_source_messages" (
    "id" INTEGER NOT NULL PRIMARY KEY AUTOINCREMENT,
    "category" varchar NOT NULL,
    "message" text
);
CREATE TABLE "yii_i18n_messages" (
  "id" INTEGER NOT NULL,
  "language" varchar NOT NULL,
  "translation" text,
  PRIMARY KEY ("id","language")
)

Note: this code works with SQLite only and all relations have to be handled by the PHP code.

Creating two Models using SqliteActiveRecords

Now we have to create the obligatory model-classes for modules\i18n\models\SourceMessage.php and modules\i18n\models\Message.php. But since we want to use the i18n.sqlite-file, both classes have to use a different database-connection than the rest of the application. Thus, we create a third file called modules\i18n\components\SqliteActiveRecord.php. I did not implement the later all by myself. At the time writing I could not find the correct reference.

To wrap things up, here are the three files:

modules\i18n\components\SqliteActiveRecord.php:

<?php
abstract class SqliteActiveRecord extends CActiveRecord
{
    const BELONGS_TO='CBelongsToRelation';
    const HAS_ONE='CHasOneRelation';
    const HAS_MANY='CHasManyRelation';
    const MANY_MANY='CManyManyRelation';
    const STAT='CStatRelation';
 
    /**
     * @var CDbConnection the default database connection for all active record classes.
     * By default, this is the 'db' application component.
     * @see getDbConnection
     */
    public static $db;
 
    private static $_models=array();            // class name => model
 
    private $_md;                               // meta data
    private $_new=false;                        // whether this instance is new or not
    private $_attributes=array();               // attribute name => attribute value
    private $_related=array();                  // attribute name => related objects
    private $_c;                                // query criteria (used by finder only)
    private $_pk;                               // old primary key value
 
    /**
     * Returns the database connection used by active record.
     * By default, the "db" application component is used as the database connection.
     * You may override this method if you want to use a different database connection.
     * @return CDbConnection the database connection used by active record.
     */
    public function getDbConnection()
    {
        if(self::$db!==null)
            return self::$db;
        else
        {
 
            // Create CDbConnection and set properties
            self::$db = new CDbConnection();
            foreach(Yii::app()->i18n_db as $key => $value)
                self::$db->$key = $value;
 
            if(self::$db instanceof CDbConnection)
            {
                self::$db->setActive(true);
                return self::$db;
            }
            else
                throw new CDbException(Yii::t('yii','Active Record requires a "db" CDbConnection application component.'));
        }
    }
}
?>

The defaultController.php

To manipulate the database records, we now create the needed actions. Since the modules\i18n\Controller\defaultController.php created by Gii is nearly empty, we have to put in some logic which is again merely the same as Gii would produce with any other Controller. For the sake of demonstration, firstly come the untouched default actions:

<?php
class DefaultController extends Controller {
 
    /**
     * @return array action filters
     */
    public function filters() {
        return array(
            'accessControl', // perform access control for CRUD operations
        );
    }
 
    /**
     * Specifies the access control rules.
     * This method is used by the 'accessControl' filter.
     * @return array access control rules
     */
    public function accessRules() {
        return array(
            array('allow', // allow authenticated user to perform 'create' and 'update' actions
                'actions' => array('index', 'view', 'create', 'update', 'delete'),
                'users' => array('@'),
            ),
            array('deny', // deny all users
                'users' => array('*'),
            ),
        );
    }
 
    /**
     * Displays a particular model.
     * @param integer $id the ID of the model to be displayed
     */
    public function actionView($id) {
        $this->render('view', array(
            'model' => $this->loadModel($id),
        ));
    }
 
    /**
     * Manages all models.
     */
    public function actionIndex() {
        $this->layout = '//layouts/column2';
        $model = new SourceMessage('search');
        $model->unsetAttributes();  // clear any default values
        if (isset($_GET['SourceMessage']))
            $model->attributes = $_GET['SourceMessage'];
 
        $this->render('admin', array(
            'model' => $model,
        ));
    }
 
    /**
     * Returns the data model based on the primary key given in the GET variable.
     * If the data model is not found, an HTTP exception will be raised.
     * @param integer the ID of the model to be loaded
     */
    public function loadModel($id) {
        $model = SourceMessage::model()->findByPk($id);
        if ($model === null)
            throw new CHttpException(404, 'The requested page does not exist.');
        return $model;
    }
    // default actions so far
}

And here is the modified logic we have to have a closer look at. Basically the complexity stems from the multiple model Validation form. Please refer to the wiki #19 How to use a single form to collect data for two or more models? to have a better insight on this topic.

// here come the modified actions
 
    /**
     * Creates a new model.
     * If creation is successful, the browser will be redirected to the 'view' page.
     */
    public function actionCreate() {
        $model = new SourceMessage;
        $messages = array();
        // create a Form for each language
        foreach (Message::LanguageList() as $lang => $language) {
            $messages[$lang] = new Message('create');
        }
        if (isset($_POST['SourceMessage']) && isset($_POST['Message'])) {
            $model->attributes = $_POST['SourceMessage'];

                foreach ($messages as $i => $item) {
                    if (isset($_POST['Message'][$i]))
                        $item->attributes = $_POST['Message'][$i];

                    $item->language = $i;
                    $valid = $item->validate() && $valid;
                }
                if ($valid) {
                    foreach ($messages as $item)
                        $item->save();

    public function actionUpdate($id) {
        $model = $this->loadModel($id);
        $items = array();
        foreach (Message::LanguageList() as $lang => $language) {
            $_message = $model->Messages(array('condition' => "language=\"{$lang}\""));
            if (!empty($_message))
                $items[$lang] = $_message[0];
            else {
                $items[$lang] = new Message('create');
                $items[$lang]->id = $model->id;
                $items[$lang]->language = $lang;
            }
        }

                }

As you can see, we create, update and delete SourceMessage and Message together. If you find a more elegant way to create and update these models – let me know.

With the Module registered, the database initiated, the Controller and Models in place it’s time to get some output.

The view files

Now it’s time to implement the actual view files, allowing letting the logic do its part. Again, we only create the necessary files with mostly default content. Please feel free to add your shim to each of those files if needed.

modules\i18n\views\default_form.php
modules\i18n\views\default\admin.php
modules\i18n\views\default\create.php
modules\i18n\views\default\update.php

        ),
    ),
));
?>

I tried to melt it down to the only necessary code. But if you go over it, you should not see nothing new. Pretty much straight forward.

Working example

So how to use this setup? Answer: the same way as with CDbMessageSource. E.g. create a new entry called #home#, select the category App and past in some text for de and en. To display that text simply use:

<?php echo Yii::t('App', '#home#', array(), 'i18n');?>

Where i18n is the reference to our protected\config\main.php setup. Not the module name but the components\i18n array. To switch the language, simply switch the language settings in the protected\config\main.php - or use you favorite method (cf. Setting and maintaining the language in Application (i18n) ).

Going live and DVCS

Now that everything is set up there is only one thing to pay attention to: the file and folder access rights. Since the i18n.sqlite is buried deep in the application tree the folder protected\modules\i18n\data has to be chmod 755. That works fine until you firstly push and pull your DVCS.

Using hooks to chmod i18n.sqlite

To my experience with Mercurial, all file (and folder) permissions will be overwritten by the hg pull -u . Therefore, Mercurial has to be instructed with a hook to chmod i18n.sqlite to 755. After init, Mercurial created a subfolder called .hg. In this folder you create or update the .hg\hgrc-file (yes without file extension):

[hooks]
changegroup = .hg/hooks.sh

Now create the referenced bash script .hg/hooks.sh an put in there:

#!/bin/zsh
# set rw sqlite
chmod 755 ./protected/modules/i18n/data/*

thats all. Now mercurial will always chmod your sqlite folder and all files within. (Since I am only familiar with mercurial, it would be a great help, if someone could post the equivalent in Git.)

Discussion

It took me about three projects to come up with this solution. I am still not very comfortable with all the chmod and the "database lies within the modules-folder"-thing. But it is the idea of a module to be independent from the rest of the application. Thus, I can live with this exception.

Hopefully you get some good ideas from this wiki. If you find errors, mistakes or ever clever hints - please let me know. Thank you all for this great community. This article really comes from the urge to give something back, after finding so much good advice.

Works great

This is amazing. We used this and it worked just as expected.

Additionally we forced translation on the CDbMessageSource so that all the content is centralized in the database and in the views we only have codes to reference the translations or the messages.

Although we do not use mercurial, we use subversion and it works as expected. When we commit, the database goes as a file and therefore any other servers have the updated messages without the need of any migrations.

Thank you very much!

I'm goint to check this out...

Quite a good article, and something to mark down (which I have).

Using SQLite as the translation DB is a great idea. All you have to do when updating is copying the file to your server. Very nice!

This could be extended to include parametrization. You upload a new version of the software that includes new personalizations, new parameters, etc. You use the upgrade script on your dev machine. You do what you need to do as a dev. You make sure that the new parameters/personalizations are to your liking. You make sure nothing is broken.

Then you upload the updated software to the production server. This includes the standard parameters/personalizations/whatever defaults provided by your supplier... Then you upload your SQLite file containing YOUR values.

You are up and running.

FYI, I work for a software shop where "personalizations" are paramount to the user experience. We have hundreds (if not thousands) of them. If, for whatever reason, we mess with that, you can be sure that our help desk will be overloaded immediately.

A "very" good reason to use and extend the idea expressed in this article.

RE: about config

@rootbear I see that this can be confusing. I added a working example above.

To your question: the CDbMessageSource arraykey is completly arbitrary. You can name it as you wish. I prefer to keep it short. Thus, I called it the same as the model name.

hope that helps.

about config

excuse my dummy or i missed something?

why this:

'i18n' => array(
            'class' => 'CDbMessageSource',
            'connectionID' => 'i18n_db',
            'sourceMessageTable' => 'yii_i18n_source_messages',
            'translatedMessageTable' => 'yii_i18n_messages', 
        ),

not this?

'messages' => array(
            'class' => 'CDbMessageSource',
            'connectionID' => 'i18n_db',
            'sourceMessageTable' => 'yii_i18n_source_messages',
            'translatedMessageTable' => 'yii_i18n_messages', 
        ),
