I installed Yii 2 advanced template. "yii migrate" command in CMD works perfectly with the default MySQL database, it populates the database with the tables migration and user as expected (see step 3 explained here: https://github.com/yiisoft/yii2-app-advanced/blob/master/docs/guide/start-installation.md)
But "yii migrate" doesn't work with the postgresql database. It produces following error message:
What's wrong, or what is missing? Data tables can be read by the Yii 2 framework if I create them manually (already tested), but migrate command doesn't want to work.
The required pdo extensions for postgresql are out-commented in the php.ini file. The web page requirements.php shows "passed" (no errors or warnings) for PDO PostgreSQL extension.
My db connection configuration in common/config/main-local.php:
'components' => [
'db' => [
'class' => 'yii\db\Connection',
'tablePrefix' => 'tbl_',
'dsn' => 'pgsql:host=localhost;port=5432;dbname=mytestdb',
'username' => 'postgres',
'password' => 'tuparnix',
'charset' => 'utf8',
// see: http://stackoverflow.com/questions/26436024/how-to-set-default-schema-in-yii2
'schemaMap' => [
'pgsql'=> [
'class'=>'yii\db\pgsql\Schema',
'defaultSchema' => 'public' //specify your schema here
],
], // PostgreSQL
],
Your command line php and your web server php is a different php.
You need to out-comment your postgres driver in command-line php.ini.
Please run these in command line for more info (I'm not sure what is windows version of these command, please chk)
which php
php -i
I have the same problem in Windows but not Linux. Perhaps, that come from driver php_pdo_pgsql + libpq.dll.
Which version you have in your phpinfo (), Postgresql 8.3.3 (windows) or 9.2.1 (linux) that would not be compatible. Looking from this side.
What is the server you are using on Windows? (xampp, easyphp, WampServer) and what version of php (5.4, 5.5, 5.6 ...).

I am using the Slim 4 framework along with Jenssegers MongoDB library and Capsule (Illuminate\Database from Laravel). I have got the MongoDB extension installed on my Linux server and everything seems ok connection wise, but I cannot seem to insert data into the database or get anything from it. I have tried with the query builder and Eloquent. My code with query builder example is below.
use Illuminate\Database\Capsule\Manager as Capsule;
$capsule = new Capsule;
$capsule->getDatabaseManager()->extend('mongodb', function($config, $name) {
$config['name'] = $name;
return new \Jenssegers\Mongodb\Connection($config);
});
$capsule->addConnection([
'host' => '127.0.0.1',
'port' => 27017,
'database' => 'testing',
'username' => '',
'password' => '',
], 'mongodb');
// Set the event dispatcher used by Eloquent models... (optional)
use Illuminate\Events\Dispatcher;
use Illuminate\Container\Container;
$capsule->setEventDispatcher(new Dispatcher(new Container));
// Make this Capsule instance available globally via static methods... (optional)
$capsule->setAsGlobal();
// Setup the Eloquent ORM... (optional; unless you've used setEventDispatcher())
$capsule->bootEloquent();
$capsule->connection('mongodb')->collection('testing')->insert([
'test1'=>'hello',
'test2'=>'world',
]);
The database and collection exist as I can see them in Compass. Can anyone see where I'm going wrong with the code or is it a configuration issue?
There were two problems, one was the driver missing as you point out, but the other was the fact my PHP is running in Linux using Vagrant and it was pointing to localhost, but the MongoDB server is running on the Windows machine and not Linux. Thanks.
Steps to install laravel/scout on Lumen framework (there are some additional steps that you need to do to make it work with lumen opposed to Laravel)
First install laravel
composer require laravel/scout
Register the service provider in the bootstrap/app.php in the provider section
$app->register(Laravel\Scout\ScoutServiceProvider::class);
Copy the configuration file (you may be able to do it with composer php artisan vendor:publish --provider="Laravel\Scout\ScoutServiceProvider" , I wasn't)
cp vendor/laravel/scout/config/scout.php config/scout.php
Ask lumen to load the configuration file, adding this line to boostrap/app.php
$app->configure('scout');
Install laravel mysql mysql driver
composer require yab/laravel-scout-mysql-driver
Change the driver setting in config/scout.php
'driver' => env('SCOUT_DRIVER', 'mysql'),
Append this to config/scout.php
'mysql' => [
'mode' => 'NATURAL_LANGUAGE',
'model_directories' => [app_path()],
'min_search_length' => 0,
'min_fulltext_search_length' => 4,
'min_fulltext_search_fallback' => 'LIKE',
'query_expansion' => false
]
run the scout index if plan to use in NATURAL_LANGUAGE or BOOLEAN
php artisan scout:mysql-index
Use like this
Model::search(searchString)->get();
You can also add other conditions
Model::search(searchString)->where(...)->get()
According to the above answer,this line:
'driver' => env('SCOUT_DRIVER', 'mysql'),
cause an error which was "Driver [mysql] not supported".
For solving the problem use "database" instead of "mysql" as a driver.
Is it somehow possible to include the mongodb connection settings into a lumen framework. As from what I saw the config/database.php is loaded internally in the lumen package. Is there a way to extend it somehow to include the mongodb connection settings?
We're actually using Lumen, Laravel, Mongo, and MySQL in one giant project so I can help you through this one. Assuming you want to use MongoDB with eloquent instead of with the raw MongoClient. You can find the library I'm using from jenssegers here.
Install MongoDB Extension
Firstly you'll need to install the dependencies for PHP to interact with mongo. The specifics for installing the mongo extension can be found on the PHP documentation.
After that you'll have to edit the php.ini files for the platforms (apache/cli/nginx) to load the extension. I added the following before Module Settings
extension=mongo.so
It goes without saying you need to restart apache/nginx after changing the configuration.
Configuring Lumen
In your root lumen folder you can add it to your requirements with the following command.
composer require jenssegers/mongodb
From there you'll need to also load the MongodbServiceProvider before Facades or Eloquent is initialized.
$app->register(Jenssegers\Mongodb\MongodbServiceProvider::class);
$app->withFacades();
$app->withEloquent();
For simplicity of organizing configuration I also created a config folder and a database.php config file. Since Lumen doesn't try to autoload or search this directory we have to tell it to load this config. I put the following line right before the loading the application routes.
$app->configure('database');
In database.php the mongodb driver requires a specific structure. I've included mysql in here as I use both, but if you're using mongo exclusively you can change default to mongodb and remove the mysql config.
return [
'default' => 'mysql',
'connections' => [
'mysql' => [
'driver' => 'mysql',
'host' => env('DB_HOST', 'localhost'),
'database' => env('DB_DATABASE', ''),
'username' => env('DB_USERNAME', ''),
'password' => env('DB_PASSWORD', ''),
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => false,
],
'mongodb' => array(
'driver' => 'mongodb',
'host' => env('MONGODB_HOST', 'localhost'),
'port' => env('MONGODB_PORT', 27017),
'username' => env('MONGODB_USERNAME', ''),
'password' => env('MONGODB_PASSWORD', ''),
'database' => env('MONGODB_DATABASE', ''),
'options' => array(
'db' => env('MONGODB_AUTHDATABASE', '') //Sets the auth DB
)
),
],
];
With the configuration out of the way you can now create a model, as of writing this to create a model for mongo (check the github page) you can use the following as a base. You can ignore the $connection variable if mongo is your default driver.
<?php
namespace App;
use Jenssegers\Mongodb\Model as Eloquent;
class Example extends Eloquent
{
protected $connection = 'mongodb';
protected $collection = 'example';
protected $primaryKey = '_id';
}
There you go, you should be able to interact with mongo normally, for the specifics of the driver check out the github page for documentation on it.
If this answer helped you could you mark it as the answer?
2016 (Update)
There is now a simple Doctrine MongoDB ODM Provider for the Lumen PHP framework.
composer require nordsoftware/lumen-doctrine-mongodb-odm

Warning
jenssegers/mongodb is a Driver sitting on top of Illumante's Eloquent ORM.
Think of it: Eloquent ORM is primary made for SQL. And let's cut with the chase: The package is the reinvention of the wheel - as a side effect, major mongodb features are not supported. Besides that, the package is unstable and unmaintained.
Be aware, jenssegers/mongodb will vent your anger and frustration:
Just a change in #Sieabah user:
instead: extension=mongo.so
choose: extension=mongodb.so

What can be wrong?
I had the similar problem at CentOS release 6.4 with Zend and PHP 5.4. PDO appears in phpinfo() but mentioned error ("could not find driver") ocurred on all pages related with database. Php 5.4 had included packages php-common, etc. and previous pdo package was obtained from alterantive yum/rpm repository. Maybe your current PDO package also fails.
Finally, in my case the solution was to install other php-pdo package (php54w-pdo.x86_64).
#yum install php54w-pdo.x86_64
I supose that you should install php55w-pdo.x86_64
#yum install php55w-pdo.x86_64
Don't forget restart Apache!
I have tried to connect PostgreSQL with Yii but is is showing
CDbConnection failed to open the DB connection.
In log it is showing
error exception.CDbException

'connectionString' => 'pgsql:host=localhost;port=5432;dbname=postgres',
'username'=>'postgres',

),
Yii Database component is build on top of PHP PDO. So Here are list of posibilities to check
Check that PostgreSQL and PostgreSQL's PDO Extension is installed and working. Also that port is right one. You can test simple PHP Script to test.

Resolved issue...by adding
LoadFile "C:/wamp/bin/php/php5.3.5/libpq.dll"
to httpd.conf file. Now phpinfo() is showing pgsql PDO.
thanks...
if you work in ubuntu make sure that you have installed pgsql library
sudo apt-get install php-pgsql
sudo service apache2 restart
after make sure that in the console and main-local there are this array
'components' => [
'log' => [
'targets' => [
[
'class' => 'yii\log\FileTarget',
'levels' => ['error', 'warning'],
],
],
],
'db' => [

'dsn' => 'pgsql:host=localhost;port=5432;dbname=yourdb',
'username' => 'user',
'password' => 'pw',
'charset' => 'utf8',
],],
In my case, it was a case of enabling the php_pdo_pgsql extension in WAMP
for those struggling with the same issue i did the work around.
environment
Yii2
server:LAMP stack 7.1
problem Driver not found i.e the "requirements.php" shows warning
"PDO PostgreSQL extension Warning All DB-related classes Required for PostgreSQL database."
i noted that pdo_pgsql.so is not packaged together with bitnami so i search for it online or try locate if installed on any php versions in /usr/lib/php
copy that file to lampstack-7.1.10-1/php/lib/php/extensions.
now go to lampstack php.ini "lampstack-7.1.10-1/php/etc/php.ini"
now place this line "extension=pdo_pgsql.so" remove ; if commented out NB you can point to the absolute path "/usr/lib/php/pdo_pgsql.so" if it existed there
restart Lamp apache server
visit requirement.php and if you see ""PDO PostgreSQL extension Passed All DB-related classes Required for PostgreSQL database.""
