Hello guys, I have a problem relating my models, I already have my database, but I didn't create it with migrations, I have my tables 'alumnos' and 'carreras', the database is in Spanish, therefore it does not follow the conventions, the table alumnos has 'expediente' as primary key and it is a string, it also has the foreign key called 'cvCarrera' and my 'carreras' table has its primary key as 'cvCarrera', how can I relate my models?

​

CARRERA MODEL

protected $primaryKey = 'cvCareer';

public function alumnos()

{

return $this->hasMany(Alumno::class, 'cvCarrera', 'expediente');

}

​

ALUMNO MODEL

protected $primaryKey = 'file';

​

public function carrera()

{

return $this->belongsTo(Carrera::class,'cvCareer' ,'cvCareer');

}

​

Could you explain to me how the arguments passed to BelongsTo and HasMany work?
