Category isn't getting related video blogs? - php

Question

I am trying to get category related video blogs by below code but i get nothing in var_dump? I want to get category related videos:
$category = VideoBlogCategoryModel::findFirst(1); // This returns category successfully and there are many video blogs having this category linked
var_dump($category->getVideoBlogs());exit;
VideoBlogModel.php
public function initialize(){
// Run base initialize code
parent::initialize();
// Configure Relation with VideoBlogCategoryModel
$this->belongsTo('category_id', VideoBlogCategoryModel::class, 'id', array(
'alias' => 'videoCategory',
'foreignKey' => true
));
}
public function getVideoCategory(){
return $this->videoCategory;
}
public function setVideoCategory($videoCategory){
$this->videoCategory = $videoCategory;
}
VideoBlogCategoryModel.php
public function initialize(){
// Run base initialize code
parent::initialize();
// Configure relation with VideoBlogModel
$this->hasMany('id', VideoBlogModel::class, 'category_id', array(
'alias' => 'videoBlogs',
'foreignKey' => true,
'cxAction' => static::ACTION_CASCADE_DELETE
));
}
public function getVideoBlogs(){
return $this->videoBlogs;
}
public function setVideoBlogs($videoBlogs){
$this->videoBlogs = $videoBlogs;
}
Let me know if anything else is required, I will share it.

Answer 1

In VideoBlogCategoryModel.php change
public function getVideoBlogs() {
return $this->videoBlogs;
}
to
public function getVideoBlogs() {
return $this->getRelated('videoBlogs');
}
Then try accessing it like:
$category = VideoBlogCategoryModel::findFirst(1);
$videos = $category->getVideoBlogs();
foreach( $videos as $video ) {
// access data here
var_dump($video->anyProperty()); // e.g $video->getId()
}

Answer 2

can you try it
$category = VideoBlogCategoryModel::findFirst(1);
$videos = $category->getVideoBlogs();
var_dump($videos->count());
var_dump($videos->toArray());
exit;
I think use var_dump for a Phalcon Collection Object is not a good idea, you can convert it to Array and Var_dump
Hope it can help you

Answer 3

Or try:
$categories = VideoBlogCategoryModel::findById($id);
