Laravel - Where on relation from different database - php

Question

I am trying to apply where condition on joined table, but I'm getting this error:
SQLSTATE[42S02]: Base table or view not found: 1146 Table 'cts.plant' doesn't exist (SQL: select * from tbl_complaint where exists (select * from tbl_plant where tbl_complaint.made_in_plant = tbl_plant.plant_id and sap_code = 99999) order by created desc limit 50 offset 0)
My model classes looks something like this:
Main Model
class Complaint extends Model {
protected $connection= 'first';
protected $table = 'complaint';
protected $primaryKey = 'complaint_id';
public function customerPlant() {
return $this->hasOne(Plant::class, 'plant_id', 'customer_plant_id')
->select('plant_id', 'sap_code', 'plant_name');
}
}
Connected Model
class Plant extends Model {
protected $connection= 'second';
protected $table = 'plant';
protected $primaryKey = 'plant_id';
public function getKeyName() {
return 'plant_id';
}
}
Data retrieval:
$query = Complaint::with([
'madeInPlantId']
$query = Complaint::whereHas('madeInPlant', function($query){
$query->where('sap_code','=','99999');
});
$query->get();
I think that problem is I'm not specifying that connected table is in another database.

Answer 1

if your tables are on the same server but different databases, you can do this.
class Complaint extends Model {
protected $table = 'cts.complaint';
protected $primaryKey = 'complaint_id';
public function customerPlant(){
return $this->hasOne(Plant::class, 'plant_id', 'customer_plant_id')
->select('plant_id', 'sap_code', 'plant_name');
}
}
class Plant extends Model{
protected $table = 'otherdatabase.plant';
protected $primaryKey = 'plant_id';
public function getKeyName() {
return 'plant_id';
}
}
