cakephp hasone and belongs join not working - php

Question

I have two tables:
users contains (id, name, email) id is the primary key.
users_details contains (user_id, address, city, postcode) user_id is the foreign key to user table.
The users.id=users_details.user_id.
I wrote user model like this in User.php
class User extends AppModel {
public $name = 'User';
public $displayField = 'name';
public $primaryKey = 'id';
var $belongsTo = 'UsersDetail';
public $hasone = array(
'UsersDetail' => array(
'className' => 'UsersDetail',
'conditions' => '',
'fields' => '',
'foreignKey' => 'id',
'order' => '',
'dependent' => true
)
);
}
I wrote the usersdetail model in UsersDetail.php
class UsersDetail extends AppModel {
public $name = 'UsersDetail';
public $displayField = 'name';
public $belongsTo = array( 'User' =>
array( 'className' => 'User','foreignKey' => 'user_id') );
public $hasone = array(
'User' => array(
'className' => 'User',
'conditions' => '',
'fields' => '',
'foreignKey' => 'id',
'order' => '',
'dependent' => true
));
}
I want to get the data from table using the join with condition. The users.id=users_details.user_id.

Answer 1

You have declared two relationships for each model association, when you should only have one going each way.
Like so:
In the userDetail Model:
public $hasMany = array(
'User' => array(
'className' => 'User',
'foreignKey' => 'user_id'
)
);
And consequently, in the User Model:
public $belongsTo = array(
'UserDetail' => array(
'className' => 'UserDetail',
'foreignKey' => 'user_id',
'conditions' => '',
'fields' => '',
'order' => ''
)
);
Check out the documentation for more details.

Answer 2

user has (id, name, email) id is the primary key.
users_details has(user_id, address, city, postcode) user_id is the foreign key to user table. Means.
Point to remember:
one to one relation - hasOne - A user table has one users_detail.
belongto - A userdetails table belongs to User table.
So, the relation between the two tables is hasone and belongsto.
find the right code below.
User model:
public $hasOne = array('UsersDetail' => array(
'className' => 'UsersDetail',
'foreignKey' => 'user_id')
);
UsersDetail model
public $belongsTo = array('User' => array(
'className' => 'Users',
'foreignKey' => 'id',
'conditions' => '',
'fields' => '',
'order' => '')
);
which provide the join precisely. You can add the conditions, order in collections.
The output query
SELECT `User`.`id`, `User`.`first_name`, `User`.`last_name`, `User`.`email`, `User`.`mobile`, `User`.`pswd`, `UsersDetail`.`user_id`, `UsersDetail`.`address`, `UsersDetail`.`city`, `UsersDetail`.`state`, `UsersDetail`.`postcode`, `UsersDetail`.`dob`, `UsersDetail`.`photo` FROM `cakedemo`.`users` AS `User` LEFT JOIN `cakedemo`.`users_details` AS `UsersDetail` ON (`UsersDetail`.`user_id` = `User`.`id`) WHERE 1 = 1
