I have this weird crash and trying for few hours to solve with no success, check everywhere on the internet and didn't find a solution.
I am running Eloquent (without laravel). I have two servers (frontend and backend). The DB is in the backend server.
I am running the exact same code to connect to the database using laravel from both servers. From the backend server everything works. In the frontend server, I get mixed result. Out of 9 tables:
three works, and I am able to retrieve the data.
three return [items:protected] => Array (), while table has data to return.
three cause fatal error SQLSTATE[42S02]: Base table or view not found Table doesn't exist
from #1 I understand that this is not related to issue with database user/password.
for #2, I checked the queries using getQueryLog(), and I run the queries in phpmyadmin, and they work.
from what I observed so far, all the tables that cause #3 are all InnoDB. Why my other tables are MyIsam I don't know.
And the exact same code works in the backend server, so it is not an issue with tables names are in singular or some other code related issue.
backend server is php 5.5.9, eloquent 5.4.45
frontend server is php 5.6.32, eloquent 5.4.36
Any idea what to do about #2 (return data empty) and #3 (php fatal error)?
Ok, found this crazy bug(s).
First, I found out that we had an old version of the database on the frontend server. It was not supposed to be there, so I didn't even think about it as a possibility.
In addition, there was a problem in the code:
$dbhost = __MYSQLDB_HOST__;
$dbuser = 'xxxxx';
$dbpass = 'xxxxx';
$dbname = 'xxxxx';
$capsule = new Capsule;
$capsule->addConnection(array(
'driver' => 'mysql',
'host' => 'localhost', // <= this is the problem!!!
'database' => $dbname,
'username' => $dbuser,
'password' => $dbpass,
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => ''
));
As you can see, when connecting to the database it used localhost instead of the $dbhost variable which contained the remote database host on the backend server.

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.
this is my logstash.conf config

the error is

Not sure if you find this useful but we experienced the same issue in two different scenarios and resolved it, which I would like to share with you,
client was not able to resolve the Primary Server address due to network related issues in docker files, it was resulting to this error, the mongodb server was up and running but the client was not able to resolve the address so the error was thrown.
mongodb was restarted (or for some reason connection was lost) and when mongodb was back online, the mongoid client (ruby) was not able to re-connect again, the solution was to restart the client as well, to establish the connection again. After investigation, I would say most likely it was a version incompatibility of the driver and mongodb server.
In general, we were not able to find a permanent solution for it and it appears to be an issue with mongodb drivers, but one thing for sure, please check the compatibility of mongodb driver and the server.
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
I'm trying to set a read/write connection in Laravel 4.2.6 and I cannot perform INSERT, but I can do UPDATE and DELETE transactions. The message that I get is:
SQLSTATE[25006]: Read only sql transaction: 7 ERROR: cannot execute INSERT in a read-only transaction
The configuration of the database is:
'connections' => [
'pgsql' => [
'read' => [
'host' => '192.168.22.10'
],
'write' => [
'host' => '192.168.33.10'
],
'driver' => 'pgsql',
'database' => 'simpo',
'username' => 'postgres',
'password' => 'xxx',
'charset' => 'utf8',
'prefix' => '',
'schema' => 'public',
],
]
I'm using Postgres 9.3 with 2 server (Virtual machines). The replication works fine and is a simple binary or "Hot Standby" replication (Master/Slave), where the stand by machine can only make read operation.
EDIT:
I tested using query builder and the INSERT works fine, but with Eloquent fails.
I'm thinking that maybe is a BUG with the connection in the Eloquent model but the unusual thing is that the only INSERT operation fails and not the UPDATE OR DELETE, so that make me think that is some operation that only happen when a INSERT is perform (Maybe with the ID that is generated?)
EDIT 2:
I finally noticed the problem. The error happens when Laravel try to insert and fetch the Id of the row. The problem happen because the framework call a 'select' method but this select execute and "INSERT ... returning 'ID'", so if the machine can only execute SELECT transaction fails because this SELECT come with a INSERT.
I make a pull request where I check if the select method start with a 'insert' operation, and depending of that get the correct connection
https://github.com/laravel/framework/pull/4914
The Bug was finally fixed and I believe that should not be problems since version 4.2.9. Checkout the same link of the pull request.
I just started to learn about ZF and Firebird because of a project I am assigned to. I have been trying to make the connection between both for several days now, but I haven't succeed yet.
I tried ZF with PDO_Mysql and it works just fine as it does Firebird connection with PHP (out of ZF), but when I try to make the connection with the Firebird adapter in ZF it keeps displaying all kinds of errors.
So, just to check. To make the connection in ZF with Firebird it should be done with the the adapter (Firebird.php) which I have configure in application.ini? I have something like this in the application.ini:
**resources.db.adapter = "Firebird"
resources.db.params.host = "localhost"
resources.db.params.dbname = "C:/wamp/www/WebTH/application/data/THDATA.gdb"
resources.db.params.username = "sysdba"
resources.db.params.password = "masterkey"**
Resulting error: ...Firebird.php): failed to open stream: No such file or directory in ...\Loader.php
I have also seen that a function needs to be added in the Bootstrap.php. If I add the function initDb in the bootstrap.php like this:
**protected function _initDb()
{
$this->bootstrap('config');
$config = $this->getResource('config');
$db = Zend_Db::factory('Firebird', array(
'host' => $config->Database->Server,
'username' => $config->Database->Username,
'password' => $config->Database->Password,
'dbname' => $config->Database->DBName,
'adapterNamespace' => 'ZendX_Db_Adapter'
));
return $db;
}**
I get the error: ...Uncaught exception 'Zend_Application_Bootstrap_Exception' with message 'Resource matching "config" not found' in ...\BootstrapAbstract.php
I would like to know what do I really need to do in order to make the connection work. Sorry if this is too obvious, but I haven't been able to find a basic connection case specific for Zend Framework and Firebird, therefore I am not really sure on what I should do and where I should go.
[Disclosure: I've never used the Firebird db.]
As you are probably aware, the Firebird adapter does not ship as part of the core ZF1 package. Looks like you can pull it from extras under the ZendX prefix:
http://framework.zend.com/svn/framework/extras/trunk/library/ZendX/Db/Adapter/
Drop the Firebird.php and Firebird/ files into a directory library/ZendX/Db/Adapter/.
If your application.ini uses the resources.db.* keys, then there is no need for an _initDb() method in your Bootstrap class. Just make sure that you include the adapterNamespace key in there, as well:
resources.db.params.adapterNamespace = "ZendX_Db_Adapter_"
You might also need to add the ZendX prefix to your autoloader namespaces:
autoloaderNamespaces[] = "ZendX_"
Not tested, but something like this should work.
