Custom Query in Cakephp 3.0? - php

Question

I want to make a custom query in Cakephp. I've been reading this: Query Builder
The problem that every example are like:
$query = $articles->find()
->where([
'author_id' => 3,
'OR' => [['view_count' => 2], ['view_count' => 3]],
]);
But in my PostController I have this:
public function view($id = null)
{
$post = $this->Posts->get($id, [
'contain' => ['Users']
]);
$this->set('post', $post);
$this->set('_serialize', ['post']);
}
I don't have anything with find(). And I don't know what is doing the last part of code
This is the query that I want to use:
public function index()
{
$query = $posts->find()->where([
'userfk' => 1
]);
}
But it isn't working, I don't know how to display the query result.
How can I have the code to working right?
Thanks!

Answer 1

If you want use Query Builder
http://book.cakephp.org/3.0/en/orm/query-builder.html
PostsController.php
public function index() {
$posts = $this -> Posts -> find() -> where(['userfk' => 1]);
$this -> set('post', $posts);
}
By the way, if the result get few $posts
Your set should be $this -> set('posts', $posts); and your view have
<?php foreach($posts as $post): ?>
<!-- your code -->
<?php endforeach; ?>
///////
EDIT
Adding Paginator option
PostsController.php
public function index() {
$this -> paginate['contain'] = ['Users'];
$this -> paginate['conditions'] = ['Posts.userfk' => 1];
$this -> set('posts' , $this -> paginate($this -> Posts));
}

Answer 2

public function index()
{
$query = $posts->find()->where([
'userfk' => 1
]);
//or you can use dynamic finders
$query = $posts->findByUserfk(1);
$this->set('post', $query);
}
in your view. print all result;
pr($post);
or you can use foreach to iterate the result
foreach($post as $i => $val) {
echo $val->userfk;
}

Answer 3

Load Model before use in function
Please use in controller
public function initialize() {
parent::initialize();
$this->loadModel('Posts');
}
Then Index function:-
public function index()
{
$posts = $this->Posts->find('all', ['conditions' => ['userfk' => 1]]);
$this->set('posts',$posts);
//pr($posts->toArray());// Print Posts array
}

I do not understand why do you pass $pots in( $query = $posts->find()).
public function index()
{
$posts = $this->Post->find('all', ['conditions' => ['userfk' => 1]]);
$this->set('post', $posts );
//print_r($posts);you can print array.
}
