这是关于拉拉维尔的。 我想在注释变量中获取post_id并将其存储到 PHPMyAdmin，但我找不到正确的代码。
当我在 CommentsController 中键入 $comment->post_id = Posting：：id((; 时，它产生了错误。 它显示"调用未定义的方法App\Models\Posting：：id((">
我在评论控制器中的代码：
<?php
namespace AppHttpControllers;
use IlluminateHttpRequest;
use AppModelsComment;
use AppModelsPosting;
use IlluminateSupportFacadesAuth;
class CommentsController extends Controller
{
/**
* Display a listing of the resource.
*
* @return IlluminateHttpResponse
*/
public function index()
{
//
}
/**
* Show the form for creating a new resource.
*
* @return IlluminateHttpResponse
*/
public function create()
{
return view('comments.create');
}
/**
* Store a newly created resource in storage.
*
* @param IlluminateHttpRequest $request
* @return IlluminateHttpResponse
*/
public function store(Request $request)
{
//if user did not fill the form properly
//error messages will popup
$this->validate($request, [
'comment' => 'required',
]);
//if user filled the form properly
//store the form
$comment = new Comment();
//to store user_id
$comment->user_id = Auth::id();
//to store post_id
//-----------------------------------------------------
//Here is the problem I have right now.
//I could not find proper code to store post_id in comment variable here.
//-----------------------------------------------------
h1$comment->post_id = ;
//to store posting
$comment->comment = $request->input('comment');
//save all user input
$comment->save();
dd($request);
}
/**
* Display the specified resource.
*
* @param int $id
* @return IlluminateHttpResponse
*/
public function show($id)
{
//
}
/**
* Show the form for editing the specified resource.
*
* @param int $id
* @return IlluminateHttpResponse
*/
public function edit($id)
{
//
}
/**
* Update the specified resource in storage.
*
* @param IlluminateHttpRequest $request
* @param int $id
* @return IlluminateHttpResponse
*/
public function update(Request $request, $id)
{
//
}
/**
* Remove the specified resource from storage.
*
* @param int $id
* @return IlluminateHttpResponse
*/
public function destroy($id)
{
//
}
}
我在PostingsController中的代码：
<?php
namespace AppHttpControllers;
use IlluminateHttpRequest;
use AppModelsposting;
use AppUser;
use IlluminateSupportFacadesAuth;
class PostingsController extends Controller
{
public function __construct()
{
$this->middleware('auth');
}
/**
* Display a listing of the resource.
*
* @return IlluminateHttpResponse
*/
public function index()
{
//this is how to get all posting, but this shows only all posting
// $postings = Posting::all();
// $postings->load('user');
//this is how to get all posting with created_at and descending order.
$postings = Posting::orderBy('created_at', 'desc')->get();
//should be function name
$postings->load('user');
return view('index')->with('postings', $postings);
}
/**
* Show the form for creating a new resource.
*
* @return IlluminateHttpResponse
*/
public function create()
{
return view('create');
}
/**
* Store a newly created resource in storage.
*
* @param IlluminateHttpRequest $request
* @return IlluminateHttpResponse
*/
public function store(Request $request)
{
//if user did not fill the form properly
//error messages will popup
$this->validate($request, [
'posting' => 'required',
]);
//if user filled the form properly
//store the form
$posting = new Posting();
//for connecting both user and posting
$posting->user_id = Auth::id();
//to store posting
$posting->post = $request->input('posting');
//save all user input
$posting->save();
return redirect()->to('/home')->with('success', 'Posting created successfully!');
}
/**
* Display the specified resource.
*
* @param int $id
* @return IlluminateHttpResponse
*/
public function show($id)
{
$posting = Posting::find($id);
return view('show')->with('posting', $posting);
}
/**
* Show the form for editing the specified resource.
*
* @param int $id
* @return IlluminateHttpResponse
*/
public function edit($id)
{
//this is the way how to find posting of authenticated user
$posting = Posting::find($id);
return view('edit')->with('posting', $posting);
}
/**
* Update the specified resource in storage.
*
* @param IlluminateHttpRequest $request
* @param int $id
* @return IlluminateHttpResponse
*/
public function update(Request $request, $id)
{
//if user did not fill the form properly
//error messages will popup
$this->validate($request, [
'posting' => 'required',
]);
//if user filled the form properly
//store the form
$posting = Posting::find($id);
//to store posting
$posting->post = $request->input('posting');
//save all user input
$posting->save();
return redirect()->to('/home')->with('success', 'Posting edited successfully!');
}
/**

*
* @param int $id
* @return IlluminateHttpResponse
*/
public function destroy($id)
{
$posting = Posting::find($id);
$posting->delete();
return redirect()->to('/home')->with('success', 'Posting deleted successfully');
}
}
如果需要更多信息，我会更新。提前谢谢你。
---附加信息--- 这是注释模型：
<?php
namespace AppModels;
use IlluminateDatabaseEloquentModel;
class Comment extends Model
{
//comments has only one post
public function post(){
return $this->belongsTo(AppPost::class, 'post_id');
}
}
这是后期模型：
<?php
namespace AppModels;
use IlluminateDatabaseEloquentModel;
class Posting extends Model
{
// For declaring postings has only one user in the model of users:
public function user(){
return $this->belongsTo(AppUser::class, 'user_id');
}
// Posting has many comments
public function comments(){
return $this->HasMany(AppComment::class,'post_id');
}
}
这是路由列表：
<?php
/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/
//when users hit my website, go to welcome.blade.php
Route::get('/', 'PostingsController@index');
//Auth::routes() is a helper class that helps you generate all the routes required for user authentication.
Auth::routes();
Route::resource('postings','PostingsController');
Route::resource('comments', 'CommentsController');
//Route::get('address_name', 'NameController');
//sometimes we deal with another one where I wrote 'HomeController@index'
Route::get('/home', 'HomeController@index')->name('home');

您需要在请求中传递post_id，然后：
内部注释创建/更新视图：
<input type="hidden" name="post_id" id="post_id" value="{{ $post->id }}" />
内部评论控制器：
//..
$comment->post_id = $request->input('post_id');
//..
