由于我是西班牙人,我用西班牙语写了收入和支出的控制者和模型.而其余的都是英语.
我手动重命名和更改了路由,控制器,迁移甚至模型.
当我运行PHP artisan migration:reset时,这是我的错误.
Undefined table: 7 ERROR: relation “expenses” does not exist (sql: alter table “expenses” drop column “location_id”)**
我使用psgql和laravel 5.3
这是我的代码:
<?PHP
namespace App;
use Illuminate\Database\Eloquent\Model;
class Expense extends Model
{
protected $fillable = ['id', 'description', 'quantity'];
public function locations()
{
return $this->hasMany('App\Location');
}
public function icons()
{
return $this->hasMany('App\Icon');
}
public function types()
{
return $this->hasMany('App\Type');
}
public function stores()
{
return $this->hasMany('App\Store');
}
}
移民:
<?PHP
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateExpensesTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('expenses', function (Blueprint $table) {
$table->increments('id');
$table->float('quantity');
$table->string('description');
$table->integer('location_id')->unsigned();
$table->integer('icon_id')->unsigned();
$table->integer('type_id')->unsigned();
$table->integer('store_id')->unsigned();
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::dropIfExists('expenses');
}
}
位置迁移:
<?PHP
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateLocationsTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('locations', function (Blueprint $table) {
$table->increments('id');
$table->string('address');
$table->float('lat');
$table->float('long');
$table->integer('store_id')->unsigned();
$table->timestamps();
$table->foreign('store_id')->references('id')->on('stores')->onDelete('cascade');
});
Schema::table('expenses', function (Blueprint $table) {
$table->foreign('location_id')->references('id')->on('locations')->onDelete('cascade');
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::table('expenses', function (Blueprint $table) {
$table->dropColumn('location_id');
});
Schema::dropIfExists('locations');
}
}
模型:
<?PHP
namespace App;
use Illuminate\Database\Eloquent\Model;
class Location extends Model
{
protected $fillable = ['id', 'address', 'lat', 'long'];
public function expenses()
{
return $this->belongsTo('App\Expense');
}
public function stores()
{
return $this->hasOne('App\Store');
}
}
希望您能够帮助我.
解决方法:
当它说
relation "expenses" does not exist
通常发生在必须在迁移之前删除您的费用表时:重置将回滚CreateLocationsTable.
检查迁移的执行顺序.
当您尝试重置时,要立即进行修复,请打开数据库,手动删除所有表,然后再次执行迁移.
