回答1:

Bacause your route parameter is question_answer, so change the controller to :

public function edit(QuestionAnswer $question_answer)
{
   dd($question_answer);
}

Alternatively, you can specifically tell the resource what the route parameter should be named :

Route::resource('faq','QuestionAnswerController')
           ->parameters(['faq' => 'questionAnswer']);

Now you can access $questionAnswer as parameter :

public function edit(QuestionAnswer $questionAnswer)
{
   dd($questionAnswer);
}

The official documentation of Naming Resource Route Parameters will be found here

Laravel resource generate prams base on url example

Route::resource('faq','QuestionAnswerController');

// this will generate url like

Route::get('faq','QuestionAnswerController@index')->name('faq,index');
Route::post('faq','QuestionAnswerController@store')->name('faq,store');
Route::get('faq/{faq}','QuestionAnswerController@show')->name('faq,show');
Route::put('faq/{faq}','QuestionAnswerController@update')->name('faq,update');
Route::delete('faq/{faq}','QuestionAnswerController@destroy')->name('faq,destroy');

so here in controller you need to accept that faq like this

public function edit(QuestionAnswer $faq) // here $faq should match with route prams
{
        return $faq;
}

or you can change route url faq to questionAnswer then your old code will work
