Question

每当我尝试将数据库迁移到Laravel时，我都会遇到此问题。

我尝试了几种选择，但似乎都不起作用。预先感谢！

用户表：

Schema::create('users', function (Blueprint $table) {
        $table->bigIncrements('id');
        $table->string('name');
        $table->string('avatar',100)->nullable();
        $table->string('country',100)->nullable();
        $table->string('email')->unique();
        $table->timestamp('email_verified_at')->nullable();
        $table->string('password');
        $table->unsignedBigInteger('product_id')->unsigned();
        $table->foreign('product_id')->references('id')->on('products');
        $table->rememberToken();
        $table->timestamps();
    });
}

创建产品表：

enter code here:

 Schema::create('products', function (Blueprint $table) {
        $table->bigIncrements('id');
        $table->string('name', 100);
        $table->decimal('price', 8, 2);
        $table->string('image', 100);
        $table->unsignedBigInteger('user_id')->unsigned();
        $table->foreign('user_id')->references('id')->on('users');
        $table->timestamps();
    });
}

将类别ID添加到圆柱产品：

enter code here:
Schema::table('products', function (Blueprint $table) {
      $table->unsignedBigInteger('category_id')->nullable();
      $table->foreign('category_id')->references('id')->on('categories');
    });
}

兴趣表：

enter code here:
  Schema::create('interests', function (Blueprint $table) {
        $table->bigIncrements('id');
        $table->string('name',100)->nullable();
        $table->timestamps();
    });
}

品牌表：

enter code here:
     Schema::create('brands', function (Blueprint $table) {
        $table->bigIncrements('id');
        $table->string('name')->nullable();
        $table->timestamps();
    });
}

在产品表中添加品牌ID：

enter code here:
   Schema::table('products', function (Blueprint $table) {
      $table->unsignedBigInteger('brand_id')->nullable();
      $table->foreign('brand_id')->references('id')->on('brands');
    });
}

创建类别兴趣：

enter code here:
     Schema::table('products', function (Blueprint $table) {
      $table->unsignedBigInteger('brand_id')->nullable();
      $table->foreign('brand_id')->references('id')->on('brands');
    });
}

2 在此处输入代码：

PDOStatement :: execute（） /Users/Ezequiel/Desktop/dandelion/vendor/laravel/framework/src/Illuminate/Database/Connection.php:458

PDOException：:(“” SQLSTATE [HY000]：一般错误：1005无法创建表`蒲公英`
