方法paginate不存在

Question

当我做:

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

它有效,但我只需要拥有用户的锦标赛.

所以我这样做:

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

我在用户模型中有一个hasMany Relationship

我得到了这个消息

Method paginate does not exist.

我该如何解决？它似乎并不复杂,但我做不到!

第二个查询的结果:Auth :: user() - >锦标赛

Collection {#385 ?
#items: array:1 [?
0 => Tournament {#386 ?
  #table: "tournament"
  +timestamps: true
  #fillable: array:17 [?]
  #dates: array:2 [?]
  #connection: null
  #primaryKey: "id"

Answer 1

在你的问题中,你paginate()很可能会调用一个集合.

在有效的答案中,你正在呼唤paginate()一位雄辩的建设者.

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正在回复你正在呼唤的雄辩的建设者paginate.

这应该会给你相同的结果:

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