Cake php 中的 ownsTo

我遵循 CakePHP 命名约定，

我需要建立“多对一”-$belongsTo 关联 Citie to Countrie ------- 意思是很多城市属于一个国家

这是Citie模型

class Citie extends AppModel
{
    var $name = 'Citie';
    var $belongsTo = array(
        'Countrie' => array(
            'className' => 'Countrie',
            'foreignKey' => 'countrie_id'
        )
    ); 
}

你可以看到这个链接返回结果时没有关联数据 DisplayCity

这是乡村模型

class Countrie extends AppModel 
{
    var $name = 'Countrie';
}

在这里你可以看到我遵循命名约定。显示所有国家/地区

原文

I'm following CakePHP naming convention

I need to make "many to one"-$belongsTo association
Citie to Countrie ------- meaning Many Cities belong to a Country

This is the Citie Model

class Citie extends AppModel
{
    var $name = 'Citie';
    var $belongsTo = array(
        'Countrie' => array(
            'className' => 'Countrie',
            'foreignKey' => 'countrie_id'
        )
    ); 
}

You can see that there are no association data when result is returned on this link
DisplayCity

This is the Countrie Model

class Countrie extends AppModel 
{
    var $name = 'Countrie';
}

Here you can see that I follow the naming convention. Display all countries

如果您遵守惯例
所以你必须有城市表的城市模型，国家表的国家模型，外键将是country_id

<?php
class City extends AppModel {
    var $name = 'City';
    var $belongsTo = array(
        'Country' => array(
            'className' => 'Country',
            'foreignKey' => 'country_id',
        )
    );
}
?>

和

<?php
class Country extends AppModel {
    var $name = 'Country';
    var $hasMany = array(
        'City' => array(
            'className' => 'City',
            'foreignKey' => 'country_id',
        )
    );

}
?>

if you are following the convention
so you must have City model for cities table, Country model for countries table and the foreignKey will be country_id

<?php
class City extends AppModel {
    var $name = 'City';
    var $belongsTo = array(
        'Country' => array(
            'className' => 'Country',
            'foreignKey' => 'country_id',
        )
    );
}
?>

and

<?php
class Country extends AppModel {
    var $name = 'Country';
    var $hasMany = array(
        'City' => array(
            'className' => 'City',
            'foreignKey' => 'country_id',
        )
    );

}
?>
