How to store activity log in mongo db from laravel? - mysql

Question

I am using spatie/laravel-activitylog to log the activities and jenssegers/laravel-mongodb connect to a Mongo database. In user Model, the user data is storing into mysql and log data need to be stored in mongodb. I am getting "Call to a member function prepare() on null"
config/activitylog.php
` /*
* This is the database connection that will be used by the migration and
* the Activity model shipped with this package. In case it's not set
* Laravel's database.default will be used instead.
*/
'database_connection' => env('ACTIVITY_LOGGER_DB_CONNECTION'),`
database.php
`'mongodb' => [
'driver' => 'mongodb',
'host' => '127.0.0.1',
'port' => '27017',
'database' => 'test_log',
'username' => '',
'password' => '',
'options' => [
'database' => 'admin'
]
],`
.env
`ACTIVITY_LOGGER_DB_CONNECTION=mongodb`
App\Models\User.php
`<?php
namespace App\Models;
// use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Contracts\Auth\MustVerifyEmail;
use Spatie\Activitylog\LogOptions;
use Spatie\Activitylog\Traits\LogsActivity;
use Jenssegers\Mongodb\Auth\User as Authenticatable;
class User extends Authenticatable implements MustVerifyEmail
{
use LogsActivity;
/**
* The attributes that are mass assignable.
*
* #var array<int, string>
*/
protected $fillable = [];
/**
* The attributes that should be hidden for serialization.
*
* #var array<int, string>
*/
/**
* The attributes that should be cast.
*
* #var array<string, string>
*/
/**
* The attributes that should be mutated to dates.
*
* #var array
*/
public function getActivitylogOptions(): LogOptions
{
return LogOptions::defaults();
}
}
`
In user Model, the user data is storing into mysql and log data need to be stored in mongodb.

Answer 1

The error message "Call to a member function prepare() on null" usually occurs when the database connection is not properly configured or the database connection does not exist.
In this case, you have set the database connection for the activity logs in the config/activitylog.php and .env files. However, it seems that the database connection is not being used properly in the User model.
To resolve this issue, you need to ensure that the database connection defined in 'config/activitylog.php' is being passed to the User model when logging activities.
You can add the following code to your User model to explicitly set the database connection:
use Illuminate\Support\Facades\Config;
protected static $logConnection = 'mongodb';
public function getActivitylogOptions(): LogOptions
{
return LogOptions::defaults()->using(Config::get('activitylog.database_connection') ?: static::$logConnection);
}
This will make sure that the activity logs are stored in the MongoDB database defined in the mongodb connection in config/database.php.

Fixed the issue with the help of this tutorial:: https://nickdevs.wordpress.com/2022/05/17/laravel-laravel-activitylog-inegrate-activity-log-with-mongodb/
The issue was with Spatie-activity-log and Jenssegers MongoDB. Spatie-activity-log uses default Model. We need to overwrite the Spatie Activity Model for Jenssegers MongoDB.
Create Activity.php in App/Models. copy the existing code from Spatie\Activitylog\Models\Activity.php from vendor/spatie/laravel-activitylog/src/Models/Activity.php. Replace the lines listed below.
remove:
namespace Spatie\Activitylog\Models;
use Illuminate\Database\Eloquent\Model;
class Activity extends Model implements ActivityContract
add:
namespace App\Models;
use Jenssegers\Mongodb\Eloquent\Model as MongoDBModel;
class Activity extends MongoDBModel implements ActivityContract
