How to save entities across two databases in Laravel (Backpack) - php

Question

I am new with Laravel and of course also with backpack.
I am using laravel 7.x and backpack 4.1 with both MySql and MongoDb.
The situation I am facing is that I have a company model with some attributes which are in MySql (both save and update working great with for the attributes stored in MySql) and other attributes that should be stored in MongoDb.
I have a CompanyPropertyCollection model for the attributes which I want to be stored in MongoDb
All these company will have a variable number of other arbitrary properties, which I want to save in mongo.
These properties may be simple scalar values or more complex values too (think arrays of objects), hence the idea to save them in mongo.
MySql Company table:
My question is the following:
What is the best practice to save attributes of an entity in two distinct databases from BackPack? I override the CreateOperation, UpdateOperation with the store() and update() functions something like this:
Company model:
class Company extends Model
{
use \Backpack\CRUD\app\Models\Traits\CrudTrait;
use SoftDeletes;
use HybridRelations;
protected $connection = 'mysql';
/**
* The attributes that are mass assignable.
*
* #var array
*/
protected $fillable = [
'name',
'company_type',
'is_active',
'package_id',
'certification_id',
];
/**
* The attributes that should be cast to native types.
*
* #var array
*/
protected $casts = [
'id' => 'integer',
'is_active' => 'boolean',
'package_id' => 'integer',
'certification_id' => 'integer',
];
/**
* #return \Illuminate\Database\Eloquent\Relations\BelongsToMany
*/
public function users()
{
return $this->belongsToMany(\App\Models\User::class);
}
/**
* #return \Illuminate\Database\Eloquent\Relations\BelongsTo
*/
public function package()
{
return $this->belongsTo(\App\Models\Package::class);
}
public function certification()
{
return $this->hasMany(\App\Models\Certification::class);
}
public function properties()
{
return $this->hasOne(\App\Models\CompanyPropertyCollection::class);
}
}
CompanyPropertyCollection model:
class CompanyPropertyCollection extends Model
{
use SoftDeletes;
protected $connection = 'mongodb';
/**
* The attributes that are mass assignable.
*
* #var array
*/
protected $fillable = [
//'company_id',
'email',
'big_news_id',
'phone.number',
'phone.country_prefix',
'phone.area_prefix',
'phone.postfix',
'year_of_foundation',
'nr_of_employees',
'nr_of_branches',
'company_size',
'subtitle',
'homepage',
'country_code',
'city',
'street',
'post_code',
'uid_nr',
'registration_nr',
'total_sales_area',
'total_annual_bisuness_volume',
'short_portrait',
'long_portrait',
'embedded_video',
'certificates',
'gallery',
];
/**
* The attributes that should be cast to native types.
*
* #var array
*/
protected $casts = [
'id' => 'integer',
'gallery' => 'array',
];
public function company()
{
return $this->belongsTo(\App\Models\Company::class);
}
}
CompanyCrudController :
public function update()
{
//$this->update( $company->properties);
$response = $this->traitUpdate();
// do something after save
//use registered observer
return $response;
}
Currently I am trying to use a CompanyObserver and on saving to store the data for mongo from the Request.
class CompanyObserver {
public function saving(Company $company)
{
//dd(request()->request);
$request = request()->request;
dd($company->properties());
//save to MongoDb
dd('saving methond on the observer');
}
}

If you need to perform some action after saving a model, like saving some user data in another db with a different type. You can override the model's save method.
Inside your model, add a method like the below
public function save(array $options = array())
{
if (parent::save($options)) {
// Model has been saved in mysql, now save in mongoDB
}
}
