CakePHP find() conditions for association entries - php

Question

I have following command, getting me entries from my DB with associated hasMany entries:
$teasers = $this->Teaser->find('all', array(
'conditions' => array(
'Teaser.published' => 1
),
));
Now also the posts entries will be fetched, due the hasMany relation.
The output looks like this:
array(
0 => array(
'Teaser' => array(
'id' => '1',
'user_id' => '63',
'token' => '56d455bc20cfb56d455bc20d08',
// this goes on
),
'Post' => array(
0 => array(
'id' => '1',
'teaser_id' => '1',
'title' => 'blabla',
'text' => 'blabla',
'published' => 1,
// this goes on
)
)
)
)
Now my question is, how can I include something in the conditions, to filter also the Post-entries?
When I enter it like this, I get an error:
$teasers = $this->Teaser->find('all', array(
'conditions' => array(
'Teaser.published' => 1,
'Post.published' => 1
)
));

Answer 1

The reason you're getting an error is that your relationship is a hasMany so when Cake does the contain it is actually doing more than one query for your find. As a result you can't specify 'Post.published' => 1 in the conditions as the Post alias won't exist in the primary query (the one retrieving your teasers).
Instead you need to pass the extra condition as part of the contain:-
$teasers = $this->Teaser->find('all', [
'contain' => [
'Post' => [
'conditions' => [
'Post.published' => 1
]
]
],
'conditions' => [
'Teaser.published' => 1,
]
]);
This will let Cake know the conditions you want to use when building the query for the posts.

Answer 2

You should read the documentation for containable and retrieving data. These are basics.
$teasers = $this->Teaser->find('all', array(
'contain' => [
'Post' => [
'conditions' => [
'published' => 1
]
]
],
'conditions' => array(
'Teaser.published' => 1,
)
));

Answer 3

You can write condition in your model Teaser.php like
public $hasMany = array(
'Post' => array(
'className' => 'Post',
'conditions' => array('Post.published' => 1)
)
);
