如何在CakePHP 3.x中为子控制器配置路由？ [英] how to configure routes for child controllers in CakePHP 3.x?

问题描述

1. 报告有许多 ReportInstances


2. ReportInstances 属于报告

$ b b

我想要有 / reports /：report-id / instances 指向操作 index_by_report_id ReportInstancesController.php

如何配置 routes.php 因此？

我试过嵌套资源如下所示：
http：/ /book.cakephp.org/3.0/en/development/routing.html#creating-nested-resource-routes

这是我的路线

  $ routes-> resources（'Reports'，[
'map'=> [
'standard '=> [
'action'=>'standard'，
'method'=>'GET'，
] 
] 
] 
 
 $ routes-> resources（'Reports'，function（$ routes）{
 $ routes-> resources（'ReportInstances'）; 
}）; 
  

当我做 / reports / 1 / instances ，它去到ReportsController寻找操作1。

请指教。

解决方案

在 routes.php

中执行此操作

  $ routes-> resources（'Parents'，function（$ routes）{
 $ routes-> resources（'Children'）; 
}）; 
 
 $ routes-> resources（'Children'）; 
  

在 ChildrenController.php ，

  protected function _prepareConditions（）{
 $ parentId = isset（$ this-> request-> params ['parent_id' ]）？ $ this-> request-> params ['parent_id']：null; 
 
 if（$ parentId == null）{
 return []; 
} 
 
 return [
'Children.parent_id'=> $ parentId 
]; 
} 
 
 public function index（）
 {
 $ conditions = $ this-> _prepareConditions（）; 
 
 $ this-> paginate = [
'contains'=> ['Parents']，
'conditions'=> $ conditions 
]; 
 // ...等等
  

您将能够执行以下操作：

1. / parents / 1 / children


2. /parents/1/children.json


3. / children


4. /children.json

>为什么这样工作？

http://book.cakephp.org/3.0/en/development/routing.html#creating-nested-resource-routes

告诉我们基本上从请求参数中检索父标识符。

它没有明确说明的是，路由

为什么你仍然拥有这些功能？

这允许/ children和/children.json在需要的时候也可以工作。

添加？

我没有尝试过，但我没有预见到任何问题

1. / parents / 1 / children / add


2. / parents / 1 / children / add.json


3. / children / add


4. /children/add.json

1. Reports has many ReportInstances
2. ReportInstances belongs to Reports

I would like to have the url /reports/:report-id/instances to point to the action index_by_report_id inside ReportInstancesController.php

How do I configure the routes.php accordingly?

UPDATE:

I tried nested resources as described here: http://book.cakephp.org/3.0/en/development/routing.html#creating-nested-resource-routes

Here are my routes

$routes->resources('Reports', [
    'map' => [
        'standard' => [
            'action' => 'standard',
            'method' => 'GET',
        ]
    ]
]);

$routes->resources('Reports', function ($routes) {
    $routes->resources('ReportInstances');
});

When I do a /reports/1/instances, it goes to ReportsController looking for action 1.

Please advise.

解决方案

Do this in your routes.php

$routes->resources('Parents', function ($routes) {
    $routes->resources('Children');
});

$routes->resources('Children');

In ChildrenController.php,

protected function _prepareConditions() {
    $parentId = isset($this->request->params['parent_id']) ? $this->request->params['parent_id'] : null;

    if ($parentId == null) {
        return [];
    }

    return [
        'Children.parent_id' => $parentId
    ];
}

public function index()
{
    $conditions = $this->_prepareConditions();

    $this->paginate = [
        'contain' => ['Parents'],
        'conditions' => $conditions
    ];
  // ... and so on

You will be able to do the following:

1. /parents/1/children
2. /parents/1/children.json
3. /children
4. /children.json

Why this works?

http://book.cakephp.org/3.0/en/development/routing.html#creating-nested-resource-routes

tells us that basically to basically retrieve the parent id from the request params.

What it does not say explicitly is that, the routes will then reuse the basic 5 functions: index, add, view, delete, edit even when you nest them under a parent url.

Why do you still have a separate resources route for the Children?

This allows the /children and /children.json to work if you need them as well.

What about add?

I haven't tried that but I do not foresee any issues with using that as

1. /parents/1/children/add
2. /parents/1/children/add.json
3. /children/add
4. /children/add.json
