Laravel 8：delete() 不会从数据库中删除

Question

I'm working with Laravel 8 to develop my forum and I wanted to add some Like and Unlike functionality to question that have been asked by users.

So Like function works fine but for Unlike, I got some problem.

Here is the method for Unliking:

public function destroy(Question $id, Request $request)
    {
        $request->user()->likes()->where('question_id', $id)->delete();

        return back();
    }

And here is the form behind this:

<form action="{{ route('destroy.likes', $show->id) }}" method="POST">
   @csrf
   @method('DELETE')
   <button class="btn">
      <i class="fas fa-thumbs-down"></i>
   </button>
</form>

So the problem is it does not delete the data from table likes at the DB.

I tried dd($request->user()); and dd($id); , they both exists with correct data, but I don't know why delete() does not work properly.

So if you know how to solve this, please let me know, I would really appreciate any idea or suggestion from you guys...

Thanks in advance.

Answer 1

It looks like you are passing a Question object in your destroy method, and then passing the whole object in your where call.

Try changing your where call to where('question_id', $id->id) , keeping in mind that your variable name is also called id . It may pay to clarify your variable name to $question .

Answer 2

There is a problem with your query, when you get the records that you want to delete:

app/Http/routes.php

Route::get('delete-records','YourController@index');
Route::get('delete/{id}','YourController@destroy')->name('destroy.likes');

Your View:

<a href="{{ route('destroy.likes', ['id' => $show->id]) }}" title="@lang('')">
   Delete
</a>

Controller Destroy Method:

public function destroy($id){
  $question = Question::find($id);
  $question ->delete();
  return back;
}
