laravel 5 如何创建枢轴 table

Question

在应用解决方案后，我遵循了 http://four.laravel.com/docs/eloquent#many-to-many and I found the same problem in How is a pivot table created by laravel 中的所有内容，我得到了迁移文件并进行了更改

public function up()
    {
        Schema::table('Card_User', function (Blueprint $table) {
          $table->increments('id');
          $table->integer('Card_id');
          $table->integer('User_id');
          $table->integer('additional_var');
        });
    }

但是当我尝试 php artisan migrate:refresh 我总是得到

[Illuminate\Database\QueryException]                                            
  SQLSTATE[42S02]: Base table or view not found: 1146 Table 'db.Card_User' d  
  oesn't exist (SQL: alter table `Card_User` add `id` int unsigned not null auto  
  _increment primary key, add `Card_id` int not null, add `User_id` int not null  
  , add `additional_var` int not null)                                    



  [PDOException]                                                                  
  SQLSTATE[42S02]: Base table or view not found: 1146 Table 'waawia.Card_User' d  
  oesn't exist

After folowwing some other webpages i tried to :

php artisan migrate:install

Delete all the database tables manually and refresh the migration

Restarted php artisan serve and now it's closed

Some other things ...

But still have the same problem

Answer 1

如果您要创建 table，请更改

Schema::table('Card_User', function (Blueprint $table) {}

到

Schema::create('Card_User', function (Blueprint $table) {}

Schema::table() 用于更改现有的 table，而 Schema::create() 则按其含义执行。
