laravel-5.1 - 分页方法不存在

Question

当我这样做时:

    $tournaments =  Tournament::paginate(Config::get('constants.PAGINATION'));

它有效，但我只需要拥有用户的锦标赛。

我也是这样的:

    $tournaments = Auth::user()->tournaments;
    $tournaments->paginate(Config::get('constants.PAGINATION'));

我在用户模型中有一个 hasMany 关系

我收到这条消息

Method paginate does not exist.

我该如何解决？看起来并不复杂，但我做不到!

第二个查询的结果:Auth::user()->tournaments

Collection {#385 ▼
#items: array:1 [▼
0 => Tournament {#386 ▼
  #table: "tournament"
  +timestamps: true
  #fillable: array:17 [▶]
  #dates: array:2 [▶]
  #connection: null
  #primaryKey: "id"
  #perPage: 15
  +incrementing: true
  #attributes: array:16 [▶]
  #original: array:16 [▶]
  #relations: []
  #hidden: []
  #visible: []
  #appends: []
  #guarded: array:1 [▶]
  #dateFormat: null
  #casts: []
  #touches: []
  #observables: []
  #with: []
  #morphClass: null
  +exists: true
  +wasRecentlyCreated: false
}
]  
}

Answer 1

在您的问题中，您很可能在集合上调用 paginate()。

在有效的答案中，您是在 Eloquent 构建器上调用 paginate()。

Auth::user()->tournaments; // dynamic property for relationship, probably a collection

Auth::user()->tournaments(); // relation type object (eloquent builder)

你的答案:

$tournaments = Tournament::where('user_id',Auth::user()->id)
    ->paginate(Config::get('constants.PAGINATION'));

where 正在返回您调用 paginate 的 eloquent 构建器。

这应该会给你相同的结果:

$tournaments = Auth::user()->tournaments()->paginate(...);
