Question

我想为公司创建类别，但出现此错误： SQLSTATE [HY000]：常规错误：1005无法创建表sanat。#sql-53e_e7d（错误号：150“外键约束格式不正确”）（SQL：更改表company_category添加约束company_category_company_id_foreign外键（company_id）引用删除级联上的companies（id）

这是我的类别迁移代码：

public function up()
{
    Schema::create('categories', function (Blueprint $table) {
        $table->increments('id')->unsigned();
        $table->string('name');
        $table->string('slug');
        $table->string('description')->nullable();
        $table->string('type');
        $table->string('imageUrl')->nullable();
        $table->timestamps();
    });
    Schema::create('article_category', function (Blueprint $table) {
        $table->integer('article_id')->unsigned();
        $table->foreign('article_id')->references('id')->on('articles')->onDelete('cascade');
        $table->integer('category_id')->unsigned();
        $table->foreign('category_id')->references('id')->on('categories')->onDelete('cascade');
        $table->primary(['article_id', 'category_id']);
    });
    Schema::create('company_category', function (Blueprint $table) {
        $table->integer('company_id')->unsigned();
        $table->foreign('company_id')->references('id')->on('companies')->onDelete('cascade');
        $table->integer('category_id')->unsigned();
        $table->foreign('category_id')->references('id')->on('categories')->onDelete('cascade');
        $table->primary(['company_id', 'category_id']);
    });

}

因此不会创建公司表和类别表。当我删除此内容时：

Schema::create('company_category', function (Blueprint $table) {
    $table->integer('company_id')->unsigned();
    $table->foreign('company_id')->references('id')->on('companies')->onDelete('cascade');
    $table->integer('category_id')->unsigned();
    $table->foreign('category_id')->references('id')->on('categories')->onDelete('cascade');
    $table->primary(['company_id', 'category_id']);
});

php artisan migration工作正常。问题出在哪里

这是我的公司迁移：

Schema::create('companies', function (Blueprint $table) {
    $table->increments('id')->unsigned();
    $table->integer('user_id')->unsigned();
    $table->foreign('user_id')->references('id')->on('users')->onDelete('cascade');
    $table->boolean('active')->default(false);
    $table->string('name');
    $table->string('email')->unique();
    $table->string('slug');
    $table->text('aboutUs');
    $table->integer('tell');
    $table->string('address');
    $table->string('tag');
    $table->string('logoUrl');
    $table->string('slideUrl')->unique();
    $table->string('facebookUrl');
    $table->string('instagramUrl');
    $table->string('telegramUrl');
    $table->string('whatsAppUrl');
    $table->string('websiteUrl');
    $table->timestamps();
});

Laravel PHP工匠迁移有错误150
