Laravel-[PDOException] SQLSTATE [42S02]：找不到基本表或视图：1146表'ip.priorities'不存在

Question

您好，我尝试使用Laravel 5.1迁移名为ideas_roles_users的表，但收到错误

[PDOException] SQLSTATE [42S02]：找不到基表或视图：1146表'ip.priorities'不存在。

Laravel我真的很陌生，希望有人能帮助我。 如您所见，我试图使一个表成多对多，并且错误来自类CreateIdeasRolesUsersTable 。 谢谢。

<?

class CreateIdeasRolesUsersTable extends Migration

{
    public function up()
    {
Schema::create('ideas_roles_users', function (Blueprint $table) {
            $table->integer('id_ideas')->unsigned();
            $table->integer('id_roles')->unsigned();
            $table->integer('id_users')->unsigned();

            $table->primary(['id_ideas', 'id_roles', 'id_users']);


            $table->timestamps();

        });

        Schema::table('priorities', function($table) {
          $table->foreign('id_ideas')->references('id')->on('ideas');
          $table->foreign('id_roles')->references('id')->on('roles');
          $table->foreign('id_users')->references('id')->on('users');
       });


    }
    public function down()
    {
        Schema::drop('ideas_roles_users');
    }
}

            $table->string('descripcion');
            $table->timestamps();

use Illuminate\Database\Migrations\Migration;

class CreateRolesTable extends Migration

    /**

     * @return void

        Schema::create('roles', function (Blueprint $table) {
            $table->increments('id');
            $table->string('nombre');
            $table->longText('descripcion');
            $table->timestamps();
        });
    }

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

Answer 1

问题是你的代码： Schema::table('priorities', function($table)它应该是。 Schema::create()不是Schema::table()因为你试图创建一个表。 Schema::table()如果要修改表，通常使用Schema::table() 。

Answer 2

发现错误。 问题是我有'Schema::table('priorities', function($table)'而不是'Schema::table('ideas_roles_users', function($table)'因为我的表名是'ideas_roles_users'。我不好，谢谢
