CakePHP：绑定模型不工作 [英] CakePHP: Bind Model not working

问题描述

我有User HABTM专业。
在用户编辑中，有一个职业复选框的列表。
当我在用户模型中定义HABTM关系时工作。
但是因为这种关系正在中断其他函数，所以我将其删除并将其放在用户控制器中。

  $ this-> User-> bindModel（
 array（
'hasAndBelongsToMany'=> 
 array（
'Profession'=> 
 array（
'className '=>'职业'，
'joinTable'=>'professions_users'，
'foreignKey'=>'user_id'，
'associationForeignKey'=>'profession_id' 
'unique'=> true，
'conditions'=>''，
'fields'=>''，
'order'=> ，
'limit'=>''，
'offset'=> ''，
'finderQuery'=> ''，
'deleteQuery'=> ''，
'insertQuery'=> ''
）
）
）
）; 
  

绑定函数的返回值也为true。

现在当我调用$ this-> User-> saveAll（$ this-> data）时，不再在professions_users表中创建行。

$ <$> find 操作，然后恢复为默认关联。您可能认为 save 操作不会触发此操作，但如果您使用 Cake的计数缓存功能或具有 afterSave的行为

尝试通过 <$ c> false 作为 Model :: bindModel 调用的第二个参数。这将使您的即时绑定持续请求的持续时间。您可以通过调用 Model :: resetAssociations ，在 saveAll 完成后显式重置关联。

I have User HABTM Professions. In user edit, there is a list of checkboxes of professions. It was working when I defined the HABTM relationship in user model. But as that relationship was interrupting other functions I removed it and put this in user controller

$this->User->bindModel(
        array(
            'hasAndBelongsToMany' => 
            array(
                'Profession' =>
                    array(
                        'className'              => 'Profession',
                        'joinTable'              => 'professions_users',
                        'foreignKey'             => 'user_id',
                        'associationForeignKey'  => 'profession_id',
                        'unique'                 => true,
                        'conditions'             => '',
                        'fields'                 => '',
                        'order'                  => '',
                        'limit'                  => '',
                        'offset'                 => '',
                        'finderQuery'            => '',
                        'deleteQuery'            => '',
                        'insertQuery'            => ''
                    )
                )
            )
        );  

The return value of that binding function is also true.

Now when I call $this->User->saveAll($this->data), rows are not created in professions_users table anymore.

Any idea?

解决方案

The default behaviour of bindModel is to exist for one find operation, then revert to the default associations. You might think a save operation wouldn't trigger this, but if you use Cake's count-caching feature, or a Behaviour with an afterSave callback that performs a find, you might be wrong.

Try passing false as a second parameter of your Model::bindModel call. This will make your on-the-fly binding last the duration of the request. You can always explicitly reset the associations after your saveAll has completed by invoking Model::resetAssociations.
