创建类别并重定向到category.index后，在laravel中找不到基表或视图

我在创建目录时遇到问题。 在我将类别关系更改为多对多之前，我没有问题

当我发布新类别，然后将其重定向到类别列表页面时，我收到以下错误：

<?php

namespace App\Models;

use Cviebrock\EloquentSluggable\Sluggable;
use Illuminate\Database\Eloquent\Model;

class Category extends Model
{
    use Sluggable;
    protected $fillable = [
        'name','slug'
    ];

    public function post()
    {
        return $this->belongsToMany(Post::class);
    }

    /**
     * Return the sluggable configuration array for this model.
     *
     * @return array
     */
    public function sluggable(): array
    {
        return [
            'slug' => [
                'source' => 'name'
            ]
        ];
    }
}

SQLSTATE[42S02]：未找到基表或视图：1146表“myblog.category_post”不存在（SQL:选择

posts

*，

category\u post

类别id作为

pivot\u类别id

，

category\u post

作为

pivot\u post id

来自

内部连接

category\u post

在

posts

上其中

category\u post

category\u id

=1）（视图：C:\Users\M0RT3Z4\Desktop\MyBlog\resources\views\admin\category\index.blade.php）

但是类别插入到数据库中。如果记录插入到类别表中，类别列表将不显示，并且我将得到错误

发布模型： 名称空间应用程序\模型

使用Cviebrock\EloquentSluggable\Sluggable； 使用Illumb\Database\Elount\Model

class Post extends Model
{
    use Sluggable;
    protected $fillable = [
        'title', 'body', 'views', 'category_id', 'user_id'
    ];

    public function comment()
    {
        $this->hasMany(Comment::class);
    }

    public function category()
    {
        return $this->belongsToMany(Category::class);
    }

    public function tags()
    {
        return $this->belongsToMany(Tag::class);
    }

    /**
     * Return the sluggable configuration array for this model.
     *
     * @return array
     */
    public function sluggable(): array
    {
        return [
            'slug' => [
                'source' => 'title'
            ]
        ];
    }

    public function hastags($id)
    {
        return in_array($id, $this->tags()->pluck('id')->toArray());
    }

    public function hascategories($id)
    {
        return in_array($id,$this->category()->pluck('id')->toArray());
    }
}

类别模型：

<?php

namespace App\Models;

use Cviebrock\EloquentSluggable\Sluggable;
use Illuminate\Database\Eloquent\Model;

class Category extends Model
{
    use Sluggable;
    protected $fillable = [
        'name','slug'
    ];

    public function post()
    {
        return $this->belongsToMany(Post::class);
    }

    /**
     * Return the sluggable configuration array for this model.
     *
     * @return array
     */
    public function sluggable(): array
    {
        return [
            'slug' => [
                'source' => 'name'
            ]
        ];
    }
}

您应该使用迁移命名约定的最佳实践来避免此问题

将
create_post_category
重命名为
category_post
（按字母顺序）

或者您可以在
$this->belongToMany（Category:：class，'Category_post'）
中指定透视表和键的其他参数
我已经更新了答案以包含透视表，请尝试它，如果它不起作用，请确保运行
php artisan migrate
