Question

我有一个模型组合，我在其中定义了连接，如

public $belongsTo = array(
        'Category' => array(
            'className' => 'Category',
            'foreignKey' => 'category_id',
            'conditions' => '',
            'fields' => '',
            'order' => ''
        )
    );

现在当我在控制器中使用代码时：

$this->Portfolio->recursive = 0;
        $this->paginate = array(
            'fields' => array('Portfolio.id', 'Portfolio.application_name','Portfolio.category_id','Portfolio.description','Portfolio.screenshots','Portfolio.icon','Portfolio.bg_color_code','Portfolio.created','Category.title','Category.id'),
            'limit' => 10,
            'order' => array(
                'Portfolio.id' => 'asc'
            )
        );

所以它在我的窗口7工作正常，但它在linux服务器上给我错误，如：

Database Error

Error: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'Category.title' in 'field list'

SQL Query: SELECT `Portfolio`.`id`, `Portfolio`.`application_name`, `Portfolio`.`category_id`, `Portfolio`.`description`, `Portfolio`.`screenshots`, `Portfolio`.`icon`, `Portfolio`.`bg_color_code`, `Portfolio`.`created`, `Category`.`title`, `Category`.`id` FROM `portfolios` AS `Portfolio` WHERE 1 = 1 ORDER BY `Portfolio`.`id` asc LIMIT 10

Notice: If you want to customize this error message, create app/View/Errors/pdo_error.ctp

我的类别模型包含

var $hasMany = array(
        'Portfolio' => array(
            'className' => 'Portfolio',
            'foreignKey' => 'category_id',
        )

    );

我的桌子

CREATE TABLE IF NOT EXISTS `categories` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `title` varchar(255) NOT NULL,
  `parent_id` int(11) NOT NULL DEFAULT '0',
  `status` enum('1','2') NOT NULL COMMENT '''1''=active,''2''=inactive',
  PRIMARY KEY (`id`)
)

我已经在调试结果中测试了它的显示

            10APP/Model\category.php
    plugins

这意味着它没有加载模型。

请帮帮我......

Answer 1

在我看来，您的数据库出了问题，而不是Linux。您的数据库是否正确链接？

$this->Portfolio->recursive = 0;
$this->paginate = array(
    'fields' => array('Portfolio.id', 'Portfolio.application_name','Portfolio.category_id','Portfolio.description','Portfolio.screenshots','Portfolio.icon','Portfolio.bg_color_code','Portfolio.created','Category.id'),
    'limit' => 10,
    'order' => array(
        'Portfolio.id' => 'asc'
    )
);`

Linux区分大小写

在Windows安装的包含文件中不正常地显示这些文件：

7APP/Model\portfolio.php
...
10APP/Model\category.php

这些文件是错误的 - 所以在linux上它们不包含在内，而你的模型将是AppModel个实例。

这将是问题的直接原因，因为没有加载模型文件，也不会有模型关联。

要解决问题，只需确保所有文件都遵循惯例 - 这意味着：

APP/Model/portfolio.php -> APP/Model/Portfolio.php
APP/Model/category.php -> APP/Model/Category.php

文件名和其他约定在the documentation中得到了支持。

Cakephp加入不在linux上工作
