Base table or view not found: 1146 Table Laravel 5.7

问题

Im getting this error when I try to save data to mysql using Laravel 5, other forms and save() methods work fine but this one:

SQLSTATE[42S02]: Base table or view not found: 1146 Table 'datatest.about_category' doesn't exist (SQL: insert into about_category (about_id, category_id) values (11, 4))

Here is my Controller store method:

public function store(AboutRequest $request)
{
    $about = new About();
    $about->title = $request->title;
    $about->body = $request->body;
    $about->save();
    $about->categories()->attach(request('category'));
    return redirect(route('abouts.create'));
}

And here is my model:

About.php

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class About extends Model
{
    public  $table = "abouts";
    public function categories()
    {
        return $this->belongsToMany(Category::class);
    }
}

Category .php

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Category extends Model
{
    protected $table = "categories";

    public  $fillable = ['id' , 'name'];

    public function abouts(){
        return $this->belongsToMany(About::class);
    }
}

For abouts table

public function up()
{
    Schema::create('abouts', function (Blueprint $table) {
        $table->increments('id');
        $table->string('title');
        $table->text('body');
        $table->timestamps();
    });
}

For categories table

public function up()
{
    Schema::create('categories', function (Blueprint $table) {
        $table->increments('id');
        $table->string('name');
        $table->timestamps();
    });
}

回答1:

Your many-to-many relationship requires three tables: abouts, categories, and about_category. You haven't created the about_category table:

Schema::create('about_category', function (Blueprint $table) {
    $table->integer('about_id')->unsigned();
    $table->integer('category_id')->unsigned();

    $table->foreign('about_id')->references('id')->on('abouts');
    $table->foreign('category_id')->references('id')->on('categories');
});
