當我單擊我的 cms 中的帖子塊時，出現(xiàn)錯誤。這是 PostsController.php 的代碼<?phpnamespace App\Http\Controllers\Blog;use App\Http\Controllers\Controller;use App\Post;use Illuminate\Http\Request;use App\Tag;use App\Category;class PostsController extends Controller{    public function show(Post $post) {        return view('blog.show')->with('post', $post);    }    public function category(Category $category) {        return view('blog.category')        ->with('category', $category)        ->with('posts', $category->post()->searched()->simplePaginate(3))        ->with('categories', Category::all())        ->with('tags', Tag::all());    }    public function tag(Tag $tag) {        return view('blog.tag')        ->with('tag', $tag)        ->with('categories', Category::all())        ->with('tags', Tag::all())        ->with('posts', $tag->posts()->searched()->simplePaginate(3));    }}這是 Post.php 模型的代碼    <?phpnamespace App;use Illuminate\Database\Eloquent\Model;use Illuminate\Database\Eloquent\SoftDeletes;use Illuminate\Support\Facades\Storage;use App\Category;class Post extends Model{    use SoftDeletes;    protected $fillable = [        'title', 'description', 'content', 'image', 'published_at', 'category_id', 'user_id',    ];/** * Delete post image from storage * HHE * @return void */    public function deleteImage() {       Storage::delete($this->image);    }    public function category() {        return $this->belongsTo(Category::class);    }    public function tag() {        return $this->belongsToMany(Tag::class);    }    /**     *     * @return bool     */    public function hasTag($tagId) {        return in_array($tagId, $this->tags->pluck('id')->toArray());    }    public function user() {        return $this->belongsTo(User::class);    }    public function scopeSearched($query) {        $search = request()->query('search');        if (!$search) {            return $query;        }        return $query->where('title', 'LIKE', "%{$search}%");    }}
