I am new to mongodb. I am working on Zend framework. My zend application is currently connected to mysql. I want to connect it with mongodb. I have successfully created a mongodb database and a collection. Now I need to link it with my application? Any help will be appreciated.
/*return array(
'db' => array(
'driver' => 'Pdo',
'dsn' => 'mysql:dbname=zf2;host=localhost',
'driver_options' => array(
PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\''
),
),
'service_manager' => array(
'factories' => array(
'Zend\Db\Adapter\Adapter'
=> 'Zend\Db\Adapter\AdapterServiceFactory',
),
),
);

use Mongo;
use Zend\Session\SaveHandler\MongoDB;
use Zend\Session\SaveHandler\MongoDBOptions;
use Zend\Session\SessionManager;
$mongo = new Mongo();
$options = new MongoDBOptions(array(
'database' => 'posts',
'collection' => 'posts',
));
$saveHandler = new MongoDB($mongo, $options);
$manager = new SessionManager();
$manager->setSaveHandler($saveHandler);
While creating a mongo client in your app, provide the hostname and port.
That's all you need to connect to mongo :)
That is my local.php config:
'db' => array(
'driver' => 'pdo_mysql',
'dns' => 'mysql:dbname=xxxx;host=localhost;',
'username' => 'xxxx',
'password' => 'xxxx',
'port' => 3306,
'charset' => 'UTF8',
'driver_options' => array(
PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\''
),
),
'service_manager' => array(
'factories' => array(
'Zend\Db\Adapter\Adapter' => 'Zend\Db\Adapter\AdapterServiceFactory',
)
)
And that is my authentication code:
$authAdapter = new AuthAdapter($sm->get('Zend\Db\Adapter\Adapter'));
$authAdapter->setTableName('users')
->setIdentityColumn('username')
->setCredentialColumn('password')
->setCredentialTreatment("SHA2(CONCAT({$salt}, ?, salt), '512') AND active = 1");
$authAdapter->setIdentity($formData['username'])
->setCredential($formData['username']);
But when I try to submit login form, zend framework throw this errors:
File: /var/www/app/vendor/zendframework/zend-authentication/src/Adapter/DbTable/AbstractAdapter.php:331
Message: The supplied parameters to DbTable failed to produce a valid sql statement, please check table and column names for validity.
File: /var/www/html/bookingSystemRewrite/vendor/zendframework/zend-db/src/Adapter/Driver/Pdo/Statement.php:244
Message:Statement could not be executed (3D000 - 1046 - No database selected)
File:/var/www/html/bookingSystemRewrite/vendor/zendframework/zend-db/src/Adapter/Driver/Pdo/Statement.php:239
Message:SQLSTATE[3D000]: Invalid catalog name: 1046 No database selected
When I debug Pdo Driver Adapter I found where is my problem.
The first problem was in that order:
'dns' => 'mysql:dbname=xxxx;host=localhost;'
it must be so :
'dsn' => 'mysql:dbname=xxxx;host=localhost;'
And the second problem was in that order:
->setCredentialTreatment("SHA2(CONCAT({$salt}, ?, salt), '512') AND active = 1");
it must be so:
->setCredentialTreatment("SHA2(CONCAT('{$salt}', ?, salt), '512') AND active = 1");
I'm sorry I'm completely new to Zend Framework 2 with some tutorials I'm trying to connect my DB connection as follows,
Created a file in
xampp\htdocs\articlemanager\application\configs\autoload\global.php
Inserted the following Zend DB connection code to global.php
<?php
return array(
'service_manager' => array(
'factories' => array(
'Zend\Db\Adapter\Adapter' => 'Zend\Db\Adapter\AdapterServiceFactory',
),
'aliases' => array(
'db' => 'Zend\Db\Adapter\Adapter',
),
),
'db' => array(
'driver' => 'PDO_MYSQL',
'dsn' => 'mysql:dbname=articlemanager;host=localhost',
'username' => 'root',
'password' => '',
'driver_options' => array(
PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\''
),
),
);
and In the Indexcontroller (\xampp\htdocs\articlemanager\application\controllers\IndexController.php) tested adding $this->db = $this->getServiceLocator()->get('db'); in the indexAction as follows
public function indexAction()
{
$this->db = $this->getServiceLocator()->get('db');
}
When I refresh page it display as
An error occurred
Application error
Can I know what I missed here?
Also I would like to know My Zend Library is in the \xampp\php\Zend and My global.php file in the xampp\htdocs\articlemanager\application\configs\autoload\global.php is it OK?
Why are you using an Alias on 'Db' ?
Try this, your driver name is different from mine.
In addition, please move your username and password to local.php.. so they do not persist in Git projects
global.php
<?php
return array(
'db' => array(
'driver' => 'Pdo',
'dsn' => 'mysql:dbname=articlemanager;host=localhost',
'driver_options' => array(
PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\''
),
),
'service_manager' => array(
'factories' => array(
'Zend\Db\Adapter\Adapter' => 'Zend\Db\Adapter\AdapterServiceFactory',
),
),
);
local.php example
<?php
return array(
'db' => array(
'username' => 'DB_USERNAME',
'password' => 'DB_PASSWORD',
),
);
database connection problems can be a number of different issues that are not necessarily obvious from looking at the creds / db config info.
have you taken a look at any logs? my application has several different logs setup - PHP error, access log, mysql error log, etc. - depending on your application, you may not have this many as discretely defined, but checking any logs you do have will give you a whole lot more information than just "An error has occurred" :)
I am taking the Zend Framework 2 Skeleton tutorial but have elected to use the mysql database in my container at my.phpcloud.com.
In the global.php file I have:
return array(
'db' => array(
'driver' => 'Pdo',
'dsn' => 'mysql:dbname=mycontainer;host=mycontainer-db.my.phpcloud.com',
'driver_options' => array(
PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\''
),
),
'service_manager' => array(
'factories' => array(
'Zend\Db\Adapter\Adapter'
=> 'Zend\Db\Adapter\AdapterServiceFactory',
),
),
);
In my local.php file I have:
return array(
'db' => array(
'username' => 'mycontainer',
'password' => 'mypassword',
),
);
I receive no errors, even if I purposely put in incorrect credentials. My view loads properly...except that there are no records. I've verified that the table exists and it is named correctly. I've verified that the table contains records.
If I return the Controller to call an array for the view, rather than a populated ViewModel, it loads the view with errors, as expected, since the AlbumTable does not load. In other words, the View is being routed correctly. It just seems like the database is returning no results. I've copied and pasted everything to the correct files and triple checked it all. I completed this tutorial locally with Zend Server and MySql and it runs perfectly. It's just the PHPCloud, which issues no errors, that seems to be returning no records from its database, whether I purposely introduce bad credentials or not.
Thanks for any assistance in advance.
Try something like this:
$dsn = sprintf(
'mysql:dbname=%s;host=%s',
get_cfg_var('zend_developer_cloud.db.name'),
get_cfg_var('zend_developer_cloud.db.host')
);
return array(
'db' => array(
'driver' => 'pdo',
'dsn' => $dsn,
'username' => 'mycontainer',
'password' => 'mypassword',
),
);
I have a Yii project with a main.php config file and dev.php config file which "inherits" from it. The files are as follows:
main.php:
<?php
// uncomment the following to define a path alias
// Yii::setPathOfAlias('local','path/to/local-folder');
// This is the main Web application configuration. Any writable
// CWebApplication properties can be configured here.
return array(
'basePath' => dirname( __FILE__ ) . DIRECTORY_SEPARATOR . '..',
'name' => 'FeedStreem',
// preloading 'log' component
'preload' => array( 'log' ),
// autoloading model and component classes
'import' => array(
'application.models.*',
'application.components.*',
'application.controllers.*',
),
// application components
'components' => array(
'db' => array(
'connectionString' => 'mysql:host=remote.host.com;dbname=dbnamehere',
'emulatePrepare' => true,
'username' => 'username',
'password' => 'password',
'charset' => 'utf8',
/*'enableProfiling' => true*/
),
'user' => array(
// enable cookie-based authentication
'allowAutoLogin' => true,
),
'authManager' => array(
'class' => 'CDbAuthManager',
'connectionID' => 'db'
),
'urlManager' => array(
// omitted
),
'errorHandler' => array(
// use 'site/error' action to display errors
'errorAction' => 'site/error',
),
'log' => array(
'class' => 'CLogRouter',
'routes' => array(
array(
'class' => 'CFileLogRoute',
'levels' => 'trace, info, error, warning',
),
),
),
),
// application-level parameters that can be accessed
// using Yii::app()->params['paramName']
'params' => array(
// this is used in contact page
'adminEmail' => 'webmaster#example.com',
),
);
dev.php:
<?php
return CMap::mergeArray(
require(dirname( __FILE__ ) . '/main.php'),
array(
'modules' => array(
'gii' => array(
'class' => 'system.gii.GiiModule',
'password' => 'SECRET',
// If removed, Gii defaults to localhost only. Edit carefully to taste.
'ipFilters' => array( '127.0.0.1', '::1' ),
),
),
'components' => array(
'db' => array(
'connectionString' => 'mysql:host=localhost;dbname=dbname2',
'emulatePrepare' => true,
'username' => 'username2',
'password' => 'password2',
'charset' => 'utf8',
),
'log' => array(
'class' => 'CLogRouter',
'routes' => array(
array(
'class' => 'CFileLogRoute',
'levels' => 'trace, info, error, warning',
),
// uncomment the following to show log messages on web pages
array(
'class' => 'CWebLogRoute',
),
),
),
),
)
);
However, when I use dev.php locally, I get the following error:
Warning: PDO::__construct() [pdo.--construct]: [2002] No connection could be made because the target machine actively (trying to connect via tcp://remote.host.com:3306) in C:\web_workspace\lib\yii\framework\db\CDbConnection.php on line 405
Which tells me the dev.php did not overwrite that 'db' config option. How can I make a config file that inherits from main.php but can overwrite options when I merge it?
As far as i see from source code it should overwrite your config:
public static function mergeArray($a,$b)
{
foreach($b as $k=>$v)
{
if(is_integer($k))
isset($a[$k]) ? $a[]=$v : $a[$k]=$v;
else if(is_array($v) && isset($a[$k]) && is_array($a[$k]))
$a[$k]=self::mergeArray($a[$k],$v);
else
$a[$k]=$v;
}
return $a;
}
Source: http://code.google.com/p/yii/source/browse/tags/1.1.8/framework/collections/CMap.php
Also official documentation says so:
If each array has an element with the same string key value, the latter will overwrite the former (different from array_merge_recursive).
Source: http://www.yiiframework.com/doc/api/1.1/CMap#mergeArray-detail
Try to determine the problem via print_r the result array and look at it inner structure. I think the problem is here.
If your project involves (or will involve) more than 1 developer, server, or customized deployment/test you have to watch out for VCS problems. For us we found it best to import a separate db.php file in config/main.php:
'db'=>require(dirname(__FILE__).'/db.php'),
The db.php file is a copy of (or symbolic link to) either db-test.php or db-deploy.php and is ignored by our VCS, while the various db-*.php files created for individual users continue to be tracked by the VCS:
bzr add protected/config/db-*.php
bzr ignore protected/config/db.php
This allows individual developers to run the system on their home machine connected to localhost databases while maintaining the deployed system's link to the central db.
I apologize if Yii has evolved much since I tested it out, but as I recall, you need to kind of work around this issue. Here is a link which outlines a few methods of doing so. It may be worth checking around to see if things have improved.
Blog article on environment dependent configuration
If you work with a dev, staging, and production environment which are all separate and maintained via git/svn/something else, I find it's easiest to ignore certain config files with frameworks that ignore environment settings. You have to make changes manually across these files at times, but this isn't a hardship as config files tend to remain similar once an app or website is established. This way you can tailor your settings for your environment for better debugging and testing on dev/staging, and otherwise better performance and no debugging on production.
How are you determining which config file to use? With a switch statement like Steve linked to?
I use an if statement in my index.php to decide which config file to use based on the server environment (as mentioned in the article Steve linked). It seems to work fine for me.
Also remember that if you are running a console application, you need to tell it to use the right conig file in protected/yiic.php also (just like in index.php).
Another thing that may be happening is CMap::mergeArray might not be merging like you want. Again, it works for me, but perhaps when the arrays are merged it is overwriting the wrong DB config string (it's choosing the wrong one)?
One way to fix this would be to NOT have the DB creds in the main.php config file, and just have them in each inheriting file. So you will need an inheriting file for each environment, and no environment will run directly off of the main.php file. This way when the arrays are merged you will always have the right DB connection string.
Good luck!
I have 2 configuration files (development and production). May be you can try my configuration.
main.php
return array(
'name' => 'My Application',
'language' => 'id',
'charset' => 'utf-8',
'basePath'=>dirname(__FILE__).DIRECTORY_SEPARATOR.'..',
// gii module
'modules' => array(
'gii' => array(
'class' => 'system.gii.GiiModule',
'password' => 'admin'
),
),
// autoloading model and component classes
'import'=>array(
'application.models.*',
'application.components.*',
),
// preloading 'log' component
'preload' => array('log'),
'defaultController' => 'site',
// application components
'components' => array(
'user' => array(
// enable cookie-based authentication
'allowAutoLogin' => true,
'loginUrl' => array('user/login'),
),
'errorHandler' => array(
// use 'site/error' action to display errors
'errorAction' => 'site/error',
),
),
// application-level parameters that can be accessed
// using Yii::app()->params['paramName']
'params'=>require('params.php'),
);
you can customize how to show the error log for your development and production server
development.php // you can customize the packages imported for development and production
return CMap::mergeArray(
array(
'components'=>array(
'db'=>array(
'connectionString' => 'mysql:host=localhost;dbname=mydb',
'emulatePrepare' => true,
'username' => 'root',
'password' => '',
'charset' => 'utf8',
'tablePrefix' => '',
),
'log' => array(
'class' => 'CLogRouter',
'routes' => array(
array(
'class' => 'CFileLogRoute',
'levels' => 'error, warning',
),
array(
'class' => 'CWebLogRoute',
),
array(
'class' => 'CDbLogRoute',
'levels' => 'trace, info, warning, error',
'connectionID' => 'db',
'autoCreateLogTable' => true,
),
),
),
),
),
require('main.php')
);
production.php
return CMap::mergeArray(
array(
'components'=>array(
'db'=>array(
'connectionString' => 'mysql:host=myserver.com;dbname=mydb',
'emulatePrepare' => true,
'username' => 'root',
'password' => 'mypassword',
'charset' => 'utf8',
'tablePrefix' => '',
),
'log' => array(
'class' => 'CLogRouter',
'routes' => array(
array(
'class' => 'CFileLogRoute',
'levels' => 'error, warning',
),
array(
'class' => 'CDbLogRoute',
'levels' => 'trace, info, warning, error',
'connectionID' => 'db',
'autoCreateLogTable' => true,
),
),
),
),
),
require('main.php')
);
just run the development or production configuration rather than main config
My problem was I was actually loading "index.php" when I wanted "index-dev.php".
My .htaccess redirect wasn't working for "localhost/" but it was working for "localhost/page".
I've got it working now by typing "localhost/index-dev.php
If you're using Yii you can also use the CMap::mergeArray function which does what the longer version of the accepted answer does already.
The last part of my index file looks like this:
$configMain = require_once(dirname(__FILE__).DIRECTORY_SEPARATOR.'protected'.DIRECTORY_SEPARATOR.'config'.DIRECTORY_SEPARATOR.'main.php');
$configServer = require_once( dirname( __FILE__ ).DIRECTORY_SEPARATOR.'protected'.DIRECTORY_SEPARATOR.'config'.DIRECTORY_SEPARATOR.'main' . $env . '.php' );
require_once($yii);
$config = CMap::mergeArray( $configMain, $configServer );
// Set Path alias for all javascript scripts
Yii::setPathOfAlias('js', dirname($_SERVER['SCRIPT_NAME']).DIRECTORY_SEPARATOR."js/");
Yii::createWebApplication($config)->run();
The part left out is at the top where I determine if I'm local or on the server.
