Laravel多态关系:将模型传递给控制器 [英] Laravel polymorphic relations: Passing model to controller

问题描述

我想使用一个控制器来保存我对多个模型的注释.因此，我使用以下存储方法创建了CommentController:

I want to use a single controller to save my comments for multiple models. So I created the CommentController, with the following store method:

public function store(Teacher $teacher, Request $request)
    {    
        $input = $request->all();

        $comment = new Comment();

        $comment->user_id = Auth::user()->id;
        $comment->body = $input['body'];

        $teacher->comments()->save($comment);

        return redirect()->back();
    }

我认为，我有:

{!! Form::open([
    'route' => ['teachers.comments.store', $teacher->id]
]) !!}

这正在工作.如果我想使用相同的CommentController来存储学校的评论，应该如何修改控制器的存储方法?

This is working. If I want to use the same CommentController to store the comments for a school, how should I modify the store method of the controller?

推荐答案

我不确定这是否是Laravel召集，但我已经执行了以下操作:

Im not sure if this is the Laravel convension, but i have done the following:

制定路线:

Route::post('/Comment/{model}/{id}', [
    // etc
]);

然后在控制器中获取模型，并对照允许的模型数组进行检查，将id传递并附加:

Then in the controller get the model and check against an array of allowed models, pass the id through and attach:

public function store(Request $request, $model, $id) {
    $allowed = ['']; // list all models here

    if(!in_array($model, $allowed) {
        // return redirect back with error
    }

    $comment = new Comment();
    $comment->user_id = $request->user()->id;
    $comment->commentable_type = 'App\\Models\\'.$model;
    $comment->commentable_id = $id;
    $comment->body = $request->body;
    $comment->save();

    return redirect()->back();
}

就像我说的那样，最有可能实现更好的方法，但这就是我做到的方式.它使代码简短有趣，并检查模型是否可以发表评论.

Like I say, there is most likely a much better way to accomplish, but this is how I've done it. It keeps it short and sweet and checks if the model can take a comment.
