我的意思是，我之前在数据库中创建了一些帖子，我可以很好地查看它们......但后来我遇到了问题..当我创建新帖子或更新现有记录（帖子）时，它失败了加载视图并抛出上述错误。
控制器：PostController.php
<?php
namespace App\Http\Controllers\User;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use App\Model\user\Post;
use App\Model\user\Tag;
use App\Model\user\Category;
class PostController extends Controller
{
public function post(Request $request, Post $slug)
{
$tags = Tag::all();
$posts = Post::all();
$categories = Category::all();
$nextPost = Post::where('id', Post::where('id', '>', $slug->id)->min('id'))->firstOrFail();
$previousPost = Post::where('id', Post::where('id', '<', $slug->id)->max('id'))->firstOrFail();
$relatedPosts = Post::where('category_id', $slug->category_id)->simplePaginate(3);
$latestNews = Post::orderBy('id', 'DESC')->get();
return view('posts.show', compact('tags', 'posts', 'categories', 'latestNews', 'previousPost', 'nextPost', 'relatedPosts'))->with('post', $slug);
}

答案 0 :(得分：0)
虽然子视图应该从父视图继承，但尝试将categories数组显式传递给_popular.blade.php：
@include('partials._popular', ['categories' => $categories'])
修改
如果将compact语句与with？
结合使用会发生什么$data = array_merge(
compact('tags', 'posts', 'categories', 'latestNews', 'previousPost', 'nextPost', 'relatedPosts'),
['post' => $slug]
);
return view('posts.show', $data);
