“SQLSTATE[HY000]：一般错误：1366 整数值不正确：”

Question

我是 Laravel 的初学者，做回复功能。 如果您能修复此代码，我将不胜感激。

我收到了这个错误：

"SQLSTATE[HY000]: General error: 1366 Incorrect integer value: '<div>da</div>' for column 'content' at row 1 (SQL: insert into `replies` (`content`, `discussion_ ▶"

2019_07_26_035335_create_replies_table.php
这就是我的桌子的样子：

use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreateRepliesTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('replies', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->integer('user_id');
            $table->integer('discussion_id');
            $table->integer('content');
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('replies');
    }
}

Answer 1

您正在为内容列使用$table->integer('content'); 整数值。而不是使用整数值，而是使用 $table->text('content'); 作为内容。我觉得您将回复正文称为内容。
