SQLSTATE[42804] 尝试 heroku 运行 php artisan migrate 时出错

SQLSTATE[42804] Error when trying to heroku run php artisan migrate

我一直在尝试从 AWS Cloud9 heroku run php artisan migrate,但没有成功。我该如何解决这个问题?如果有人能帮助我,我将不胜感激。非常感谢!


我收到三个错误,都是在说

SQLSTATE[42804]: Datatype mismatch: 7 ERROR:  column "administered" cannot be cast automatically to type smallint                            
  HINT:  You might need to specify "USING administered::smallint"

问题迁移文件如下:

<?php

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

class ChangeFilariasisMedicationsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::table('filariasis_medications', function (Blueprint $table) {
            $table->dropColumn('administered');            
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::table('filariasis_medications', function (Blueprint $table) {
            $table->smallInteger ('administered');
        });
    }
}

这是相关模型。

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

 // 追加
use App\AdministeredDate;
use App\User;
use Illuminate\Notifications\Notifiable; 
use App\Notifications\ReminderMail; 

class FilariasisMedication extends Model
{
    protected $fillable = [
      'start_date',
      'number_of_times',
      'counter',
      'administered'
    ];
    
    protected $dates = [
      'start_date',  
    ];
    
    use Notifiable;

  
    /**
     * この投薬スケジュールを所有するユーザ(Userモデルとの関係を定義)
     */
    public function medication_user()
    {
      return $this->belongsTo(User::class);
    }
    
    /**
     * この投薬スケジュールに属する投薬確定日(AdministeredDateモデルとの関係を定義)
     */
    public function administered_date()
    {
      return $this->hasMany(AdministeredDate::class);
    }
    
}

您在迁移中的括号前放置了 space,请将其删除。

来自 $table->smallInteger ('administered');

$table->smallInteger('administered');
