How to join two tables using models in cakephp - cakephp

Question

I just created 2 models UsersModel and UserpicsModel and try to get both records but it is returning Error: Call to a member function find() on a non-object.
//UsersModel.php
class Users extends AppModel
{
public $hasMany = array(
'Userpics' => array(
'className' => 'Userpics'
)
);
}
//UserpicsMdoel.php
class Userpics extends AppModel
{
public $belongsTo = array(
'Users' => array(
'className' => 'Users',
'foreignKey' => 'uid'
)
);
}
//RecipesController.php
class RecipesController extends AppController {
public $uses =array('Users','Userpics');
public function view() {
$users = $this->Users->Userpics->find('all');
print('<pre>');
print_r($users);
print('<pre>');
exit;
}
}

Answer 1

first: you are not following cake conventions: models should be singular and not plural.
But the actual problem here is that the model files names are wrong: if you still want to use your conventions then the name for the Users model should be Users.php and not UsersModel.php
the same for Userpics
read this useful answer about how to debug this kind of error.
But if you decide to use the cake naming conventions (and I strongly suggest you to do so) consider doing the following:
//User.php (table users)
class User extends AppModel
{
....
}
//UserPic.php (table user_pics)
class UserPic extends AppModel
{
....
}
//RecipesController.php
class RecipesController extends AppController {
public $uses =array('User','UserPic');
public function view() {
$users = $this->User->UserPic->find('all');
print('<pre>');
print_r($users);
print('<pre>');
exit;
}
}

Answer 2

//UsersModel.php
class Users extends AppModel
{
public $hasMany = array(
'Userpics' => array(
'className' => 'Userpics',
'foreignKey' => 'uid'
)
);
}
