我正在做我的第一个项目，尝试使用 CakePHP。基本上我有一个网站，我希望用户能够搜索存储在 MySQL 数据库中的不同锻炼。

当用户输入搜索词时，我只想返回名称中包含搜索词的任何锻炼。最重要的是，我希望他们能够应用过滤器将搜索范围缩小到特定的肌肉群。

过滤器通过查询字符串传递给搜索操作，搜索词使用 post 方法传递。

首先，这是我现在关心的两个模型：

class Workout extends AppModel {
    public $name = 'Workout';
    public $hasAndBelongsToMany = array(
        'MuscleGroup' =>
            array(
                'className'              => 'MuscleGroup',
                'joinTable'              => 'workouts_muscle_groups',
                'foreignKey'             => 'workout_id',
                'associationForeignKey'  => 'muscle_group_id',
                'unique'                 => true,
                'conditions'             => '',
                'fields'                 => '',
                'order'                  => '',
                'limit'                  => '',
                'offset'                 => '',
                'finderQuery'            => '',
                'deleteQuery'            => '',
                'insertQuery'            => ''
            )
    );
}


class MuscleGroup extends AppModel {
    public $name = 'MuscleGroup';
    public $hasAndBelongsToMany = array(
        'Workout' =>
            array(
                'className'              => 'Workout',
                'joinTable'              => 'workouts_muscle_groups',
                'foreignKey'             => 'muscle_group_id',
                'associationForeignKey'  => 'workout_id',
                'unique'                 => true,
                'conditions'             => '',
                'fields'                 => '',
                'order'                  => '',
                'limit'                  => '',
                'offset'                 => '',
                'finderQuery'            => '',
                'deleteQuery'            => '',
                'insertQuery'            => ''
            )
    );
}

现在下面是我的 WorkoutsController 中的搜索操作：

function search() {
    $hasFilters = false;
    $filters = array(
        "abs" => false, 
        "back" => false, 
        "biceps" => false, 
        "chest" => false, 
        "forearms" => false, 
        "legs" => false, 
        "shoulders" => false, 
        "triceps" => false
    );

    if(isset($this->params['url']['abs']))
        if($this->params['url']['abs'] == "1")
            $filters['abs'] = $hasFilters = true;
    if(isset($this->params['url']['back']))
        if($this->params['url']['back'] == "1")
            $filters['back'] = $hasFilters = true;
    if(isset($this->params['url']['biceps']))
        if($this->params['url']['biceps'] == "1")
            $filters['biceps'] = $hasFilters = true;
    if(isset($this->params['url']['chest']))
        if($this->params['url']['chest'] == "1")
            $filters['chest'] = $hasFilters = true;
    if(isset($this->params['url']['forearms']))
        if($this->params['url']['forearms'] == "1")
            $filters['forearms'] = $hasFilters = true;
    if(isset($this->params['url']['legs']))
        if($this->params['url']['legs'] == "1")
            $filters['legs'] = $hasFilters = true;
    if(isset($this->params['url']['shoulders']))
        if($this->params['url']['shoulders'] == "1")
            $filters['shoulders'] = $hasFilters = true;
    if(isset($this->params['url']['triceps']))
        if($this->params['url']['triceps'] == "1")
            $filters['triceps'] = $hasFilters = true;


    $query = $this->request->data['search'];

    //insert code here to actually perform the search!     

}

我真的希望有一种简单的方法来做到这一点，但我整晚都在翻阅文档，似乎找不到任何相关的例子。在 EntityFramework 中，我可以简单地说：

List<Workout> results = context.Workouts.Where(w => w.Name.Contains(searchTerm) && w.MuscleGroups.Any(g => g.Id == mg_id)).ToList();

注意：不知道 C# 语法是否接近正确，但从模型中访问数据的便利性与我记忆中的接近。

我怎样才能从 CakePHP 获得等价物？

尝试使用 MuscleGroup ID 进行过滤，而不是使用它们的名称。无论如何，我想用户会从列表中选择它们。

然后，find()应该像这样工作：

$this->Workout->find(
    'all',
    array(
        'conditions' => array(
            'Workout.name LIKE' => '%'.$searchTerm.'%',
            // List of included MuscleGroups:
            'MuscleGroup.id' => array(1, 5, 9, 17)  
        )   
    )   
);

请注意，您需要注意相关的 MuscleGroup 是否包含在 Workout 查询中，可以通过设置$this->Workout->recursive = 1或（推荐）使用更灵活的 ContainableBehavior。
