CakePHP调用未定义的方法stdClass:：read（）错误,php,cakephp,Php,Cakephp,我是CakePHP新手，我仍然在学习基础知识，通过在一个实时项目中工作，并在必要时从CakePHP文档中获得帮助。目前，我遇到了以下问题：我最近更改了数据库表名和结构，因此我被迫更改视图、控制器和模型名。更改名称后，无论何时运行index.ctp页面，都会出现以下错误： Fatal error: Call to undefined method stdClass::read() in C:\wamp\www\sdb\app\controllers \home_loan_distributions

我是CakePHP新手，我仍然在学习基础知识，通过在一个实时项目中工作，并在必要时从CakePHP文档中获得帮助。目前，我遇到了以下问题：我最近更改了数据库表名和结构，因此我被迫更改视图、控制器和模型名。更改名称后，无论何时运行index.ctp页面，都会出现以下错误：

Fatal error: Call to undefined method stdClass::read() in C:\wamp\www\sdb\app\controllers
\home_loan_distributions_details_controller.php on line 32

以前，我的视图文件夹名为

home\u loan\u distributions

，现在它被重命名为

home\u loan\u distributions\u details

我以前的控制器名称是

home\u loan\u distributions\u controller.php

，当前名称是

home\u loan\u distributions\u details\u controller.php

。代码：

class HomeLoanDistributionsDetailsController extends AppController {

        var $name = 'HomeLoanDistributionsDetails';

        function index() {
            $user = $this->Session->read('User');
            $user_role = $user['User']['user_role_id'];
            $actions = $this->Session->read('actions');
            $display_actions = array();

            foreach ($actions as $action) {
                array_push($display_actions, $action['pm_controller_actions']['name']);
            }
            $this->set('display_actions', $display_actions);
            $this->set('user_role', $user_role);


            $branch_id = 18;
            $this->set('branch_id', $branch_id);
            $conditions = array('branch_id' => $branch_id);


            $this->set('HomeLoanDistributionsDetails', $this->paginate($conditions));
            $this->HomeLoanDistributionDetail->Branch->recursive = 0;
            $this->set('BranchDetailInformation', $this->HomeLoanDistributionDetail->Branch->read(array('Branch.id', 'Branch.name', 'RegionalOffice.name', 'DistrictOffice.name', 'SubDistrictOffice.name', 'ClusterOffice.name'), $branch_id));
        }

class HomeLoanDistributionDetail extends AppModel {

    var $name = 'HomeLoanDistributionDetail';
    var $actsAs = array('Logable' => array(
            'userModel' => 'User',
            'userKey' => 'user_id',
            'change' => 'list', // options are 'list' or 'full'
            'description_ids' => TRUE // options are TRUE or FALSE
    ));
    var $validate = array(
        'entry_date' => array(
            'rule' => 'date',
            'message' => 'Enter a valid date',
            'allowEmpty' => true
        ),
        'branch_id' => array('numeric'),
        'customer_id' => array('numeric'),
        'loan_amount' => array('numeric'),
        'service_charge' => array('numeric'),
        'security' => array('numeric'),

    );

    //The Associations below have been created with all possible keys, those that are not needed can be removed
    var $belongsTo = array(
        'Branch' => array(
            'className' => 'Branch',
            'foreignKey' => 'branch_id',
            'conditions' => '',
            'fields' => 'id,name',
            'order' => ''
        )
    );

    function paginate($conditions, $fields, $order, $limit, $page = 1, $recursive = null, $extra = array()) {

      $recursive = 0;

      $group = $fields = array('branch_id', 'entry_date');
      $order = array('entry_date DESC');
      $limit = 4;
      $this->paginateCount($conditions);
      return $this->find('all', compact('conditions', 'fields', 'order', 'limit', 'recursive', 'group'));
      }

      function paginateCount($conditions = null, $recursive = 0, $extra = array()) {

      $recursive = 0;
      $group = $fields = array('branch_id', 'entry_date');
      $order = array('entry_date DESC');
      $results = $this->find('all', compact('conditions', 'fields', 'order', 'limit', 'page', 'recursive', 'group'));
      return count($results);
      }


}

我的模型以前名为

home\u loan\u distribution.php

，现在名为

home\u loan\u distribution\u detail.php

。代码：

class HomeLoanDistributionsDetailsController extends AppController {

        var $name = 'HomeLoanDistributionsDetails';

        function index() {
            $user = $this->Session->read('User');
            $user_role = $user['User']['user_role_id'];
            $actions = $this->Session->read('actions');
            $display_actions = array();

            foreach ($actions as $action) {
                array_push($display_actions, $action['pm_controller_actions']['name']);
            }
            $this->set('display_actions', $display_actions);
            $this->set('user_role', $user_role);


            $branch_id = 18;
            $this->set('branch_id', $branch_id);
            $conditions = array('branch_id' => $branch_id);


            $this->set('HomeLoanDistributionsDetails', $this->paginate($conditions));
            $this->HomeLoanDistributionDetail->Branch->recursive = 0;
            $this->set('BranchDetailInformation', $this->HomeLoanDistributionDetail->Branch->read(array('Branch.id', 'Branch.name', 'RegionalOffice.name', 'DistrictOffice.name', 'SubDistrictOffice.name', 'ClusterOffice.name'), $branch_id));
        }

class HomeLoanDistributionDetail extends AppModel {

    var $name = 'HomeLoanDistributionDetail';
    var $actsAs = array('Logable' => array(
            'userModel' => 'User',
            'userKey' => 'user_id',
            'change' => 'list', // options are 'list' or 'full'
            'description_ids' => TRUE // options are TRUE or FALSE
    ));
    var $validate = array(
        'entry_date' => array(
            'rule' => 'date',
            'message' => 'Enter a valid date',
            'allowEmpty' => true
        ),
        'branch_id' => array('numeric'),
        'customer_id' => array('numeric'),
        'loan_amount' => array('numeric'),
        'service_charge' => array('numeric'),
        'security' => array('numeric'),
        'loan_taken_term' => array('numeric'),
        'purpose_id' => array('numeric'),
        'installment_amount' => array('numeric'),
        'installment_service_charge' => array('numeric'),
    );

    //The Associations below have been created with all possible keys, those that are not needed can be removed
    var $belongsTo = array(
        'Branch' => array(
            'className' => 'Branch',
            'foreignKey' => 'branch_id',
            'conditions' => '',
            'fields' => 'id,name',
            'order' => ''
        )
    );

    function paginate($conditions, $fields, $order, $limit, $page = 1, $recursive = null, $extra = array()) {

      $recursive = 0;

      $group = $fields = array('branch_id', 'entry_date');
      $order = array('entry_date DESC');
      $limit = 4;
      $this->paginateCount($conditions);
      return $this->find('all', compact('conditions', 'fields', 'order', 'limit', 'recursive', 'group'));
      }

      function paginateCount($conditions = null, $recursive = 0, $extra = array()) {

      $recursive = 0;
      $group = $fields = array('branch_id', 'entry_date');
      $order = array('entry_date DESC');
      $results = $this->find('all', compact('conditions', 'fields', 'order', 'limit', 'page', 'recursive', 'group'));
      return count($results);
      }


}

我的猜测是：可能是我在重命名所有东西时弄乱了命名约定。问题肯定在控制器的这一行内：

$this->set('BranchDetailInformation',
$this->HomeLoanDistributionDetail->Branch->read(array('Branch.id', 'Branch.name',
'RegionalOffice.name', 'DistrictOffice.name', 'SubDistrictOffice.name', 'ClusterOffice.name'),
$branch_id));

每当我注释掉这一行时，我就不再收到上面提到的错误消息并加载我的视图页面（尽管仍然缺少一些数据，因为我需要在视图中显示那些与分支相关的数据）我不知道我的问题到底是什么，但至少我知道它在哪里。我需要有人来确定它

我的CakePHP版本是1.2.5，PHP版本是-5.2

没有用于模型的函数

read

。如果要查找一些模型数据，请尝试-

$this->set('BranchDetailInformation', $this->HomeLoanDistributionDetail->Branch->find('all', $consitions);

$conditions

将是您想要提供的所有需求的数组。有关更多信息，请参阅。

显然，问题似乎与我的模型中使用的

分支数组的'className'=>'Branch'
元素有关，因为stdClass:：read（）
方法与类而不是模型相关。但我发现问题出在别处。这个错误是问题的一部分，但它本身并不是真正的问题
今天早上我发现我的模型名是HomeLoanDistributionDetail
，但我的表名是home\u loan\u distributions\u details
（因为其他人更改了表名）。CakePHP约定要求对应的表名为复数，模型类名为单数且大小写一致
引述:
模型类名称是单数的和CamelCased的。Person、BigPerson和ReallyBigPerson都是常规模型名称的示例
与CakePHP模型对应的表名是复数和下划线。上述模型的基础表分别是people、big_people和really_big_people
考虑到上述约定，我只需将模型类名从HomeLoandDistributionDetail
重命名为HomeLoandDistributionDetail
，以便与表名home\u loan\u distributions\u details
匹配。此外，我必须将模型文件名从home\u loan\u distribution\u detail.php
更改为home\u loan\u distributions\u detail.php

这样做之后，我停止了获取错误，并成功地从表中检索数据并查看它。
$this->HomeLoanDistributionDetail->Branch
我认为Branch
在这里被标识为一个类，而不是一个模型。也许这就是为什么我可以使用read（）
方法？类似的代码存在于项目的其他部分，我见过他们这样写，而且这些代码工作得很好<代码>分支机构
我想这里不是一个模型。你能添加那个代码吗<代码>分支

是模型的一个实例。您还定义了关系<代码>读取是一种

会话

组件而非模型的方法。
