I'm seeing the example that the docs gives:
$robotPart = RobotsParts::findFirst(1);
// RobotsParts model has a n-1 (belongsTo)
// relationship to RobotsParts then
$robot = $robotPart->robots;I want to do the same, but with groups and grades. So it will be:
$group = Group::findFirst();
$grade = $group->grade;But it isn't working. What I'm doing wrong? I didn't understand it well?
Can you show us how you've definied the relationship against both models? Are you using namespaces? Are you using aliases for the column/property names?
No namespaces, aliases, or else. Only the models (Curso = Grade, Grupo = Group). 1-n relation (grade has many groups):
<?php
use Phalcon\Mvc\Model;
class Curso extends Model
{
public function initialize()
{
$this->hasMany('id', 'Grupo', 'curso_id');
}
}<?php
use Phalcon\Mvc\Model;
class Grupo extends Model
{
public function initialize()
{
$this->belongsTo('curso_id', 'Curso', 'id');
}
}It must work:
$grupo = Grupo::findFirst();
$curso = $grupo->curso; // returns an instance of Curso or falseCould you var_dump($curso); please?
Sorry for the waiting. I always do first a vardump to new things like this, and before I asked here it gives me NULL.
I get, from the DB, each row from each table. But when I try to get a Grade from a Group, it doesn't work.
I just can't... I just can't continuing living in this world.
The error was that the models didn't uploaded correctly by the time I tried it (don't know why)...
I don't want to live anymore...
