php - 如何生成嵌套资源的链接？

Question

我正在开发的 Laravel 应用程序有两个资源。

第二个资源的路由如下:

$ php artisan route:list | grep -i activity 

POST       | admin/procedure/{id}/activity                  | admin.procedure.{id}.activity.store   | (...)\ProcedureActivityController@store    
GET|HEAD   | admin/procedure/{id}/activity                  | admin.procedure.{id}.activity.index   | (...)\ProcedureActivityController@index    
GET|HEAD   | admin/procedure/{id}/activity/create           | admin.procedure.{id}.activity.create  | (...)\ProcedureActivityController@create   
GET|HEAD   | admin/procedure/{id}/activity/{activity}       | admin.procedure.{id}.activity.show    | (...)\ProcedureActivityController@show     
PUT|PATCH  | admin/procedure/{id}/activity/{activity}       | admin.procedure.{id}.activity.update  | (...)\ProcedureActivityController@update   
DELETE     | admin/procedure/{id}/activity/{activity}       | admin.procedure.{id}.activity.destroy | (...)\ProcedureActivityController@destroy  
GET|HEAD   | admin/procedure/{id}/activity/{activity}/edit  | admin.procedure.{id}.activity.edit    | (...)\ProcedureActivityController@edit     

我将此设置称为嵌套资源，因为事件是在过程下定义的。定义或路线如下所示:

Route::resource('procedure', 'ProcedureController');
Route::resource('procedure/{id}/activity', 'Admin\ProcedureActivityController');

我想为属于过程 3 的新事件生成 POST 操作的链接，就像使用 list-all-procedures 路由一样；

$ php artisan tinker
>>> route('admin.procedure.index')
=> "http://localhost/admin/procedure"

>>> route('admin.procedure.{id}.activity')
InvalidArgumentException with message 
        'Route [admin.procedure.{id}.activity] not defined.'

有没有办法使用标准助手和外观生成嵌套资源的链接？

Answer 1

您的嵌套资源的路由定义不太正确。

Route::resource('procedure/{id}/activity', 'Admin\ProcedureActivityController');

应该是:

Route::resource('procedure.activity', 'Admin\ProcedureActivityController');

此外，我不确定您如何在 URI 中获取 {id}，因为 ResourceRegistrar 将根据资源名称创建参数。基于您的第一个资源定义应为 {procedure} 的定义。

您最终应该为索引路由提供一个类似于 admin.procedure.activity.index 的路由名称。

route('admin.procedure.activity.index', ['procedure' => $id]);

Laravel 5.1 - Controllers - Restful - Nested Resources

Route::resource('photos.comments', 'PhotoCommentController');

This route will register a "nested" resource that may be accessed with URLs like the following: photos/{photos}/comments/{comments}.
