Builder.php行2405中的BadMethodCallException
Builder.php行2405中的BadMethodCallException
提问于 2018-06-01 05:06:42
我是Laravel的新手，我正在尝试创建一个基本的博客，用户可以在其中喜欢一篇文章。然而，我得到了以下错误：
BadMethodCallException第2405行:调用未定义的方法Builder.php \数据库\查询\生成器：：likes()
下面是正在使用的代码：
PostController.php
class PostController extends Controller
{
public function getIndex()
{
$posts = Post::orderBy('created_at', 'desc')->paginate(2);
return view('blog.index', ['posts' => $posts]);
}
public function getAdminIndex()
{
$posts = Post::all();
return view('admin.index', ['posts' => $posts]);
}
public function getPost($id)
{
$post = Post::find($id);
return view('blog.post', ['post' => $post]);
}
public function getLikePost($id)
{
$post = Post::find($id);
$like = new Like();
$post->likes()->save($like);
return redirect()->back();
}
}Post.php
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Post extends Model
{
protected $fillable = ['title', 'content'];
public function likes()
{
return $this->hasMany('App\Like');
}
}Like.php
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Like extends Model
{
public function post()
{
return $this->belongsTo('App\Post');
}
}post.blade.php
@extends('layouts.master')
@section('content')
<div class="row">
<div class="col-md-12">
<p class="quote">{{ $post-> title}}</p>
</div>
</div>
<div class="row">
<div class="col-md-12">
<p>{{ count($post->likes) }} Likes | <a href="{{ route('blog.post.like', [ 'id' => $post->id ]) }}">Like</a></p>
</div>
</div>
<div class="row">
<div class="col-md-12">
<p>{{ $post->content }}</p>
</div>
</div>
@endsectionroutes.php
Route::get('/', [
'uses' => 'PostController@getIndex',
'as' => 'blog.index'
]);
Route::get('post/{id}', [
'uses' => 'PostController@getPost',
'as' => 'blog.post'
]);
Route::get('post/{id}/like', [
'uses' => 'PostController@getLikePost',
'as' => 'blog.post.like'
]);
Route::get('about', function () {
return view('other.about');
})->name('other.about');
Route::get('Register', function () {
return view('auth.register');
})->name('auth.register');
Route::get('Login', function () {
return view('auth.login');
})->name('auth.login');我看不出问题出在likes方法中，也看不出在控制器中。由于Cloud 9 IDE的限制，我只能使用Laravel 5.2。
dd的输出($post)：

我不确定您的likes表字段是什么？
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Like extends Model
{
$fillable = ['post_id', 'user_id']; //YOU HAVE TO REPLACE THIS WITH YOUR FIELDS NAME
public function post()
{
return $this->belongsTo('App\Post');
}
}然后您的post控制器如下所示：
class PostController extends Controller
public function getLikePost($id)
{
$post = Post::find($id);
$like = new Like(['user_id' => Auth::user()->id]);
$post->likes()->save($like);
return redirect()->back();
}

在程序中创建了多对多关系后，问题以某种方式自行解决了。
希望我有更多的细节，但我不知道这是怎么发生的。
非常感谢你的帮助。
