Hello!
I have the next question.
There is part of code:
$result = $this->find('all', array(
'contain' => array(
'User' => array(
'fields' => 'id',
'conditions' => array(
'id' => $user_id
)
)
),
'fields' => 'url'
));
This find() called in method of Project model class and I want to
retrieve just projects where User.id equal some user id passed to my
method.
User HABTM Project and Project HABTM User.
But after executing I have the next:
app/views/projects/index.ctp (line 1)
Array
(
[0] => Array
(
[Project] => Array
(
[url] => http://purpled.biz
[id] => 1
)
[User] => Array
(
[0] => Array
(
[id] => 4
[ProjectsUser] => Array
(
[user_id] => 4
[project_id] => 1
[projects_users_role_id] => 0
)
)
)
)
[1] => Array
(
[Project] => Array
(
[url] => http://google.com
[id] => 2
)
[User] => Array
(
[0] => Array
(
[id] => 4
[ProjectsUser] => Array
(
[user_id] => 4
[project_id] => 2
[projects_users_role_id] => 0
)
)
)
)
[2] => Array
(
[Project] => Array
(
[url] => http://test.com
[id] => 3
)
[User] => Array
(
)
)
)
As you see there is the last array with empty [User] array, so how can
I exclude this empty array (whole [2] array I mean) without using
foreach/if blocks? I know that using bindModel will do all as well but
this is not for my question ;) So, how?
