我想在几个不同的表中获取数据库中的一些字段数据,并且在post模型中建立了表之间的关系,并且在ListingPageController中,我分配了post模型并创建了名为$ posts的变量以在list.blade.php页面中使用它当我尝试使用它时会给我这个错误,请帮助
以下代码是ListingPageController页面:
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Post;
class ListingPageController extends Controller
{
public function index(){
return view('front.listing');
}
public function listing($id){
$posts = Post::with(['comments','category','creator'])->where('status',1)->where('category_id',$id)->
orWhere('created_by',$id)->orderBy('id','DESC')->paginate(3);
return view('front.listing',compact('posts'));
}
}
下面的代码是listing.blade.php页面
@foreach($posts as $key=>$post)
@if($key === 0)
<div class="entity_wrapper">
<div class="entity_title header_purple">
<h1><a href="{{ url('/category') }}/{{ $post->category_id }}">{{ $post->category->name }}</a></h1>
</div>
<!-- entity_title -->
<div class="entity_thumb">
<img class="img-responsive" src="{{ asset('post') }}/{{ $post->main_image }} " alt="{{ $post->title }}">
</div>
<!-- entity_thumb -->
<div class="entity_title">
<a href="{{ url('/details') }}/{{ $post->slug }}" target="_blank"><h3> {{ $post->title }} </h3></a>
</div>
<!-- entity_title -->
<div class="entity_meta">
<a href="#">{{ date('F j- Y',strtotime($post->created_at)) }}</a> , by: <a href="{{ url('/author') }}/{{ $post->creator->id }}">{{ $post->creator->name }} </a>
</div>
<!-- entity_meta -->
<div class="entity_content">
{{ str_limit( $post->short_description,200,'...' ) }}
</div>
<!-- entity_content -->
<div class="entity_social">
