CakePHP是否将所有INT字段视为连接表的ID？

我正在尝试保存用户，他们的 Profiles 和一些标签，我的连接表链接配置文件和标签不断搞砸 .

配置文件模型称为“讲师”，标记模型称为“主题” . 教师有一个电话号码和一个邮政编码，由于某种原因，CakePHP认为这些是在我的连接表中创建条目时应该使用的字段 .

My Join table always comes out as:

id | instructor_id | subject_id |
1  | 90210         | 1          | // thinks that the zip code is an instructor_id
2  | 1112223333    | 1          | // thinks that the phone number is an instructor_id
3  | 1             | 1          | // thinks that user_id is an instructor_id
4  | 1             | 1          | // the actual instructor_id, this one's correct
5  | 90210         | 2          |
6  | 1112223333    | 2          |
3  | 1             | 2          |
4  | 1             | 2          |

My Models:

class Instructor extends AppModel
{
    var $name = 'Instructor';
    var $belongsTo = array('User', 'State');
    var $hasAndBelongsToMany = array(
        'Subject' => array(
            'className'                 => 'Subject',
            'joinTable'                 => 'instructors_subjects',
            'foreignKey'                => 'instructor_id',
            'associationForeignKey'     => 'subject_id',
            'unique'                    => true,
            'conditions'                => '',

            'finderQuery'               => '',
            'deleteQuery'               => '',
            'insertQuery'               => ''
        )   
    );
}

class Subject extends AppModel
{
    var $name = 'Subject';
    var $hasAndBelongsToMany = array(
        'Instructor' => array(
            'className'                 => 'Instructor',
            'joinTable'                 => 'instructors_subjects',
            'foreignKey'                => 'subject_id',
            'associationForeignKey'     => 'instructor_id',

            'limit'                     => '',
            'offset'                    => '',
            'finderQuery'               => '',

            'insertQuery'               => ''
        )   
    );
}

My Model Associations:

User hasOne Instructor
Instructor belongsTo User
Instructor hasAndBelongsToMany Subject
Subject hasAndBelongsToMany Instructor

My form data looks like:

Array
(
    [User] => Array
        (
            [username] => MrInstructor
            [password] => cddb06c93c72f34eb9408610529a34645c29c55d
            [group_id] => 2
        )

    [Instructor] => Array
        (
            [name] => Jimmy Bob
            [email] => jbob@gmail.com
            [phone] => 1112223333
            [city] => Beverly Hills
            [zip_code] => 90210
            [states] => 5
            [website] => www.jimmybobbaseballschool.com
            [description] => Jimmy Bob is an instructor.
            [user_id] => 1
            [id] => 1
        )

    [Subject] => Array
        (
            [name] => hitting, pitching
        )

)

My function for processing the form looks like:

function instructor_register()
    {
        $this->set('groups', $this->User->Group->find('list'));
        $this->set('states', $this->User->Instructor->State->find('list'));

        if (!empty($this->data)) {
            // Set the group to Instructor
            $this->data['User']['group_id'] = 2;

            // Save the user data
            $user = $this->User->save($this->data, true, array(
                'username',
                'password',
                'group_id'
            ));

            // If the user was saved, save the instructor's info
            if (!empty($user)) {
                $this->data['Instructor']['user_id'] = $this->User->id;
                $instructor = $this->User->Instructor->save($this->data, true, array(
                    'user_id',
                    'name',
                    'email',
                    'phone',
                    'city',
                    'zip_code',
                    'state_id',
                    'website',
                    'description'
                ));

                // If the instructor was saved, save the rest
                if(!empty($instructor)) {
                    $instructorId = $this->User->Instructor->id;
                    $this->data['Instructor']['id'] = $instructorId;

                    // Save each subject seperately
                    $subjects = explode(",", $this->data['Subject']['name']);
                    foreach ($subjects as $_subject) {
                        // Get the correct subject format
                        $_subject = strtolower(trim($_subject));

                        $this->User->Instructor->Subject->create($this->data);

                        $this->User->Instructor->Subject->set(array(
                            'name' => $_subject
                        ));

                        $this->User->Instructor->Subject->save();

                        echo ' ';
                        print_r($this->data);
                        echo ' ';
                    }
                }
            }
        }
    }
